A method of protecting employees from cave-ins, from material that could fall or roll from an excavation face or into an excavation, or from the collapse of adjacent structures. Protective systems include support systems, sloping and benching systems, shield systems, and other systems that provide the necessary protection.

4.6 Sloping
A method of protecting employees from cave-ins by forming sides of an excavation that are inclined away from the excavation so as to prevent cave-ins. The angle of incline required to prevent a cave-in varies with differences in such factors as the soil type, environmental conditions of exposure, and application of surcharge loads.

4.7 Support System
A structure such as underpinning, bracing, or shoring, which provides support to an adjacent structure, underground installation, or the sides of an excavation.

4.8 Trench
A narrow excavation made below the surface of the ground. In general the depth is greater than the width, but the width of a trench measured at the bottom is not greater than 15 feet. If forms or other structures are installed or constructed in an excavation so as to reduce the dimension measured from the forms or structure to the side of the excavation to 15 feet or less, the excavation is also considered to be a trench.

This safe work practice (SWP) provides contingency measures for spills and unintentional discharges from handling and transporting hazardous materials. Spill and discharge control practices should follow specific procedures to ensure the safety of responders and bystanders and to limit environmental impacts.

1.0 GENERAL PROCEDURES GENERAL PROCEDURES GENERAL PROCEDURES Immediate action should be taken to control and contain any spill following the general guidelines below:
· Unnecessary personnel should be kept away from the spill or discharge. · The hazardous area should be isolated.
· If the spill or discharge creates a hazardous situation or results in injury or an environmental release, the emergency procedures of the HASP should be implemented. Emergency response telephone numbers, designated contacts, and special reporting procedures are presented in the HASP. · Personnel should stay on the upwind side of the spill or discharge. · Entry into a confined space or low area where liquids or vapors may accumulate should be avoided.
· Sources of ignition should be eliminated if the spill or discharge involves combustible materials.
· Drains, manholes, waterways, sewers, and the like should be identified and covered or protected.
· The spill should be controlled or absorbed using appropriate media or devices. · When the spill or discharge is fully contained and under control, spill or discharge material should be collected.
· Following cleanup, the spill area should be evaluated by collecting soil samples and screening the area with air monitoring instruments.

This safe work practice (SWP) describes situations where heat stress is likely to occur and provides procedures for the prevention and treatment of heat-related injuries and illnesses.

Wearing personal protective equipment (PPE), especially during warm weather, puts employees at considerable risk of developing heat-related illness. Health effects from heat stress may range from transient heat fatigue or rashes to serious illness or death.

Many factors contribute to heat stress, including PPE, ambient temperature and humidity, workload, and the physical condition of the employee, as well as predisposing medical conditions.

However, the primary factors are elevated ambient temperatures in combination with fluid loss.

Because heat stress is one of the more common health concerns that may be encountered during field activities, employees must be familiar with the signs, symptoms, and various treatment methods of each form of heat stress. Heat stroke is the most serious heat-related illness—it is a threat to life and has a 20 percent mortality rate. Direct exposure to sun, poor air circulation, poor physical condition, and advanced age directly affect the tendency to heat stroke. Table 1 lists the most serious heat conditions, their causes, signs and symptoms, and treatment.

Training is an important component of heat stress prevention. Employees are instructed to recognize and treat heat-related illnesses during 8-hour health and safety refresher and first aid training courses. When working in hot environments, specific steps should be taken to lessen the chances of heat-related illnesses. These include the following:
• Ensuring that all employees drink plenty of fluids (Gatorade® or its equivalent) • Ensuring that frequent breaks are scheduled so overheating does not occur • Revising work schedules, when necessary, to take advantage of the cooler parts of the day (such as working from 5:00 a.m. to 11:00 a.m. and 6:00 p.m. to nightfall).

When PPE must be worn (especially Levels A and B), suggested guidelines relating to ambient temperature and maximum wearing time per excursion are as shown in Table 2. ~

To monitor the level of an employee’s heat stress, the following should be measured:
• Heart Rate: Count the radial (wrist) pulse during a 30-second period as early as possible in the rest period; if heart rate exceeds 110 beats per minute at the beginning of the rest period, shorten the next work cycle by one-third and keep the rest period the same.

If the heart rate still exceeds 110 beats per minute at the next period, shorten the following work cycle by one-third.
• Oral Temperature: Use a clinical thermometer (3 minutes under the tongue) to measure the oral temperature at the end of the work period. If oral temperature exceeds 99.6 °F (37.6 °C), shorten the next work cycle by one-third without changing the rest period. If oral temperature still exceeds 99.6 °F at the beginning of the next rest period, shorten the following work cycle by one-third. Do not permit a worker to wear impermeable PPE when his or her oral temperature exceeds 100.6 °F (38.1 °C).

Biological hazards, or “biohazards,” include plants, animals or their products, and parasitic or infectious agents that may present potential risks to worker health. This safe work practice (SWP) discusses procedures for working with biohazards, preventive guidelines, and first-aid procedures for the most common hazards field staff are likely to encounter. This SWP does not address biohazards such as those associated with medical waste. Procedures for working with this type of biohazard should be addressed in the site-specific health and safety plan (HASP), construction health and safety plan (C-HASP), job safety analyses (JSAs), activity hazard analyses (AHAs), or other health and safety project planning documents on a case-by-case basis.

During preparation for site work, the document preparer should consider which plants, animals, and other biological agents may be encountered; assess their potential risk to project personnel; and attach this SWP to the document if necessary. Office health and safety representatives should become familiar with biological hazards indigenous to the geographical area in which most of their office personnel work and assist in evaluating the risks to personnel on projects staffed from their offices. SWPs for insects, snakes, animals, plants, waterborne pathogens (giardia), and hantavirus are provided below.

1.0 INSECTS INSECTS INSECTS
SWPs for reducing the chance of insect bites or stings and for treating bites or stings are listed below.
· Workers should keep as much skin area covered as possible by wearing longsleeved shirts, long pants, and a hat. Pant legs should be tucked into socks or boots and shirts into pants. In addition, workers should wear light colored clothing.
· A proven insect repellent should be used on bare skin and clothing. · When possible, tall grasses and brush that could harbor ticks should be avoided. · Several times during the day and at the end of the work day, each worker should perform a check for evidence of imbedded ticks or previous bites. Particular attention should be paid to the scalp, neck, ankles, back of the legs, and waist. ~

Workers should never reach into spaces with unprotected arms.
· Workers should watch carefully for bees around open soft drinks or food. · If a worker is stung by a bee, the stinger should be carefully removed, if present.

The wound should be washed and a cold pack applied. Allergic reaction should be watched for and is evidenced by extreme swelling, redness, pain, or difficulty breathing.
· If a worker is stung or bit by a spider or scorpion, medical attention should be obtained immediately.

2.0 SNAKES
SWPs for encounters with snakes and for treating snakebites are listed below. · Workers should avoid walking in areas known to harbor snakes. Workers should be cautious when picking up or moving items that have been on the ground. · Workers should wear boots made of heavy material that protect the ankles and pants. Heavy work gloves should be worn for picking up items. · If one snake is encountered, others may be present. Workers should leave the area by retracing their steps.
· If a worker is bitten, the wound should be washed and the injured area immobilized and kept lower than the heart, if possible. Ice or a tourniquet should not be applied to a snake bite. The wound should not be cut. If medical care is more than 30 minutes away from a work site, a snakebite kit should be available on site and workers should know how to use it.

3.0 ANIMALS ANIMALS ANIMALS
SWPs for encounters with animals and for treating associated wounds are listed below. ~

· Workers should avoid animal droppings (including bird droppings). Pathogens, some of which can become airborne, may still be present in the droppings. · If a worker is bitten, he or she should get away from the animal to avoid further bites. Workers should not try to stop, hold, or catch the animal. · If the wound is minor, it should be washed with soap and water. Any bleeding should then be controlled, and an antibiotic ointment and dressing should be applied. All animal bite wounds should be watched for signs of infection. · If the wound is bleeding seriously, the bleeding should be controlled but the wound should not be cleaned. Medical assistance should be summoned immediately.
· If a rabid animal is suspected, immediate medical attention should be summoned. If possible, workers should try to remember what the rabid animal looked like and the area in which it was last seen. The animal should be reported by calling the local emergency number.

4.0 PLANTS
SWPs for plants are as follows:
· Workers should be aware of the types and appearances of poisonous plants in the work site area. Poison ivy, oak, and sumac are the most frequently encountered plants that can cause reaction from casual contact. If a worker is extremely sensitive to these plants, he or she should avoid the area entirely because airborne drift could be sufficient to cause a reaction. Other plants, such as fireweed, can cause painful, short-term irritation and should be avoided as well. Workers should avoid touching face and eye areas after contact with any suspicious plant.

Disposable outerwear should be used, if necessary, and workers should not touch the material with bare hands during removal if the outerwear may have contacted poisonous plants.
· If contact with a poisonous plant has occurred, the affected area should be immediately washed thoroughly with soap and water. If a rash or weeping sore has already begun to develop, a paste of baking soda and water should be applied to the area several times a day to reduce discomfort. Lotions such as Calamine or Caladryl should be applied to help soothe the area. If the condition gets worse and affects large areas of the body or the face, a doctor should be consulted.
· Bushy and wooded areas should be thoroughly checked for thorn-bearing trees, brush, and bramble. In some cases, impalement can cause severe pain or infection.

5.0 WATERBORNE PATHOGENS WATERBORNE PATHOGENS WATERBORNE PATHOGENS-GIARDIA GIARDIA GIARDIA Giardia is a waterborne pathogen consisting of a protoplasmic parasite of the mammalian digestive tract. Giardia is present worldwide, with the highest occurrence in areas with poor sanitation. In the United States, most reported cases are in mountainous regions where drinking water is obtained from streams and is unfiltered or untreated.

Giardia is contracted by ingesting water contaminated with giardia cysts in the dormant state.

Giardia parasites can only thrive in the digestive tracts of mammals. Dormant giardia organisms enter water through the feces of infected animals or humans. Giardia symptoms include severe diarrhea and upset stomach. Some people are asymptomatic but can transmit the disease to others. Medical treatment of giardia can be difficult and unpleasant; therefore, prevention is critical. Precautions for preventing exposure to giardia are listed below. · Workers should assume that all fresh water streams are infected with the giardia organism and not drink any untreated water.
· Team members collecting sediment and water samples from streams should wash their hands thoroughly with soap and water after collecting the samples. ~

Water should be treated for drinking or cooking with iodine or another recommended giardia treatment before use.

6.0 HANTAVIRUS HANTAVIRUS HANTAVIRUS
Hantavirus pulmonary syndrome (HPS) is a potentially fatal infection caused by a rodent-borne hantavirus. HPS begins with a brief illness most commonly characterized by fever, muscle pain, headache, coughing, and nausea or vomiting. Other early symptoms include chills, diarrhea, shortness of breath, abdominal pain, and dizziness. In the first identified cases of HPS, this stage of the infection lasted 2 to 5 days before victims were hospitalized. Typically, by the time of hospitalization, victims were found to have tachycardia (a heart rate of greater than 100 beats per minute) and tachypnea (a breathing rate of greater than 20 breaths per minute). Fever was also common. In most cases, death occurred within 2 to 16 days of the onset of symptoms, and victims exhibited pulmonary edema and severe hypotension.

Currently, experts believe that HPS is spread by the deer mouse (Peromyscus maniculatus).

Though the deer mouse has been found to be the primary host of hantavirus, several other rodent species have also tested positive for the virus. Pinon mice (Peromyscus truei), brush mice (Peromyscus boylii), and western chipmunks (Tamia spp.) are also likely to carry the virus.

Also, cases of HPS have been reported in areas of the United States where these particular rodents are not indigenous.

Infected rodents shed the virus in their urine, feces, and saliva. Humans can be exposed to the virus through (1) inhalation of suspended rodent excreta or dust particles containing rodent excreta, (2) introduction of rodent excreta into the eyes or broken skin, and (3) ingestion of food or water contaminated by rodent excreta. HPS has a reported mortality rate of 55 percent. Transmission of hantavirus from infected individuals to healthy persons has not been documented.

Prevention of HPS infection is essential because no known antidote and no specific treatment exists for treating HPS. Therefore, employees should practice risk reduction and control measures. Guidelines for workers in locations that may have rodent infestations or habitats are listed below.
· The best approach for HPS control and prevention is through environmental hygiene practices that deter rodents from colonizing the work environment. ~

The controlled version of this document can be found on the Tetra Tech Intranet. · Information about the symptoms of HPS and detailed guidance on preventive measures should be provided to all employees assigned to field activities. · Medical attention should be sought immediately for workers who develop a febrile or respiratory illness within 45 days of the last potential exposure to rodents. Attending physicians should be advised of each worker’s potential for occupational exposure to hantavirus. Physicians should contact local health authorities promptly if hantavirus-associated illness is suspected. A blood sample should be obtained from the affected worker and forwarded with the baseline serum sample through the state health department to the Centers for Disease Control and Prevention for hantavirus antibody testing. · Respiratory protective equipment should be worn when handling rodents, when removing rodents from traps, and when working in areas with evidence of rodent droppings or hair. Respiratory protective equipment should include, at a minimum, a half-face air-purifying respirator (APR) or powered APR equipped with a high-efficiency particulate air (HEPA) filter (P100). Full-face regulators may be needed under some circumstances. Respiratory protective equipment should be used in accordance with Occupational Safety and Health Administration regulations.
· Dermal protection should be worn when handling rodents or traps containing rodents, or if contact with contaminated surfaces could occur. Dermal protection should include rubber or plastic gloves that should be washed and disinfected before removal.
· A trap contaminated with rodent urine or feces or in which a rodent was captured should be disinfected with a commercial disinfectant or a 0.4 percent bleach solution. A dead rodent should be disposed of by placing the carcass in a plastic bag containing enough general-purpose household disinfectant to thoroughly wet the carcass. The bag should be sealed and disposed of by burning or by burying it in a 2- to 3-foot-deep hole. Local and state health departments can also provide appropriate disposal methods.

To prevent injuries and adverse health effects, the following general safe work practices (SWP) are to be followed when lifting and carrying while in an office or field environment. These SWPs establish a pattern of general precautions and measures for reducing risks associated with back injury and trauma associated with improper lifting and carrying of heavy objects. This list is not inclusive and may be amended as necessary.
· First, inspect the area where the load will be lifted, transported, and then deposited. Remove any obstacles that could present a tripping or other hazard. · Perform a "test lift" by slightly pushing or moving the object to gauge your ability to safely lift/move/deposit the item without injuring yourself. IF YOU ARE NOT CONFIDENT THAT YOU

CAN MOVE THE OBJECT WITHOUT INJYURING YOURSELF - THEN EITHER GET A MECHANICAL LIFTING AID OR GET HELP. DO NOT ATTEMPT TO MOVE THE OBJECT YOURSELF. · Get as close to the object as you can, and bend at the knees (not at the back). · Assure that can get a firm grasp on the object.
· Keeping the load as close to you body as possible, lift with your legs, and avoid turning or twisting while lifting, carrying, or depositing the load. · Carry the object in a manner that it does not obstruct your vision and so that you can maintain a clear line of sight of your path of travel and the area where you will set it down. · Set the object down using the same techniques as you did in lifting it (don't turn or twist, keep it close to your body, use your legs - not your back).

PREVENTION of SUN EXPOSURE

The online version of this document supersedes all other versions. Paper copies of this document are uncontrolled. The controlled version of this document can be found on the Tetra Tech Intranet.

By far, the most common cause of skin cancer is overexposure to the sun. Ninety percent of all skin cancers occur on parts of the body that not usually covered by clothing. People who sunburn easily, and those with fair skin and red or blond hair are more prone to develop skin cancer. The amount of time spent in the sun also affects a person's risk of skin cancer.

Premature aging of the skin also occurs with prolonged sun exposure. Tetra Tech encourages personnel to avoid prolonged exposure to the sun, and recommends the following:
• Sunburn can occur during any time of the year. To avoid sunburn, wear hats with wide brims.
• Use sunscreen with a Sun Protective Factor (SPF) rating of 15 or higher. • To prevent skin cancer:
o Cover up with a wide brimmed hat and a bandanna for your neck. Wear longsleeved shirts and pants which the sun cannot penetrate. o Use sunscreens to help prevent skin cancer as well as premature aging of your skin. Use a Sun Protective Factor (SPF) rating of 15 or higher. o Apply sunscreen at least an hour before going into the sun and again after swimming or perspiring a lot.
o Do not use indoor sun lamps, tanning salons/parlors, or tanning pills. • You can still get burned on a cloudy day. Try to stay out of the direct sun at midday, because sun rays are their strongest between 10 a.m. and 3 p.m. Beware of high altitudes - where there is less atmosphere to filter out the ultraviolet rays. Skiers should remember that snow reflects the sun's rays, too.
• Know your skin. Whatever your skin type, do a monthly self-examination of your skin to note any moles, blemishes or birthmarks. Check them once a month and if you notice any changes in size, shape or color, or if a sore does not heal, see your physician without delay.

Hazards that may be presented by underground utilities include explosion and fire, electrocution, toxic exposures, pathogens, and drowning.

5.2.1 Identifying and Locating Underground Utilities
The possibility of the existence of underground utilities must be evaluated as early as possible in the planning phase for any project which involves intrusive activities. The Project Safety Checklist or equivalent should be used for documentation of the identification of this potential hazard and the procedures to be followed to address them. The following sections describe various methods for identifying and locating utilities on a site. Plans should be verified during the readiness review.

The Ground Disturbance Permit (Excavations/Utility Locate) or equivalent must be completed before any activities meeting the definition of excavation are conducted. This document is intended to be used as a guide during the process of locating and marking utilities in the area and in the overall process of underground utilities management during the course of the project.

All underground utilities on a site involving excavation, must be located and identified before intrusive activities commence, by one or more of the following entities:
 The Utility Owner
 A Private or Public Utility Locating Service
 An Approved Tetra Tech Competent Person
These options are described in greater detail in the following Sub-Sections:

5.2.1.1 Pre-Planning and the Site Specific Health and Safety Plan The Site-Specific Health and Safety Plan developed for the project must:
 Identify the location and types of underground utilities that are believed to be present on the site.
 Reference this procedure and describe how it will be implemented on the project.  Contain an Activity Hazard Analysis in which the hazards associated with underground utilities are identified, as well as the measures used to control them. ~

These can usually be obtained via the Internet.
 Contain clear and concise procedures to be followed in the event that contact with underground utilities occurs.
 Address underground utilities and potential associated scenarios in the emergency response section.

5.2.1.2 “One-Call” Locating and Marking Services
Every state has utility marking service programs having various names such as “One-Call”, “DigSafe”, “Call-Before-You-Dig”, “Dig-Safely”, and many others. These services will identify the types and locations of any utility that may exist in an area to be excavated, as long as the property is in the public domain.

The appropriate One-Call service for the jurisdiction where the project is located must be contacted prior to beginning excavation work. The One-Call agency should be given as detailed a description of the property as possible; address, cross street, utility pole numbers, physical description, etc.

Notification to the One-Call service shall allow sufficient lead time for the agency to mark the utilities before excavation begins. The lead times vary, but range from two to ten days, depending on the state of jurisdiction.

A complete listing of One-Call agencies and telephone numbers for all states is available in the “Call-Before-You-Dig Call Center Directory”, which can be accessed online.

Once notified, the One-Call agency will provide the contractor with a unique “locate number” or “reference number”. This reference number must be kept in the project files by the Competent Person or designee. Additionally, the reference numbers have expiration dates, which may vary depending on the particular One-Call agency. The valid period of the locate number and required renew notification date shall be requested from the One-Call agency.

On a project with multiple contractors, each contractor must request a separate locate number.

Under no circumstances will any other contractor or entity be allowed to work under our locate number. Subcontractors to Tetra Tech may excavate under the locate number secured by Tetra ~

Tech, provided that they are excavating within the area which was previously white-lined by Tetra Tech and subsequently marked. However, the One-Call agency must be contacted and notified of this arrangement so that the subcontractor can be recorded as working under the existing locate number. If a Tetra Tech subcontractor will be excavating in an area not white-lined by Tetra Tech, then the Tetra Tech subcontractor must request a new locate.

The area where work is to be performed shall be white-lined by Tetra Tech personnel before the locating service goes to the site.

It is good practice to arrange a pre-excavation meeting at the project site with the personnel performing the utility location and marking. This meeting will facilitate communications, coordinate the marking with actual excavation, and assure identification of high-priority utilities.

The One-Call agency should provide the identities of the utility owners that will be notified of the locate request. This information shall be recorded on the Ground Disturbance Permit maintained in the project files. The contact person and phone number for each utility owner shall also be recorded.

The utility owners should provide a “positive response” relative to the locate request, which can consist of two types of action by the utility owner. The facility owner or operator is required to 1) mark it’s underground utilities with stakes, paint, or flags, or 2) notify the excavator that the utility owner/operator has no underground utilities in the area of the excavation.

The positive responses shall be recorded on the Ground Disturbance Permit and cross-checked with the list of utility owners that the One-Call agency stated that they would notify. If it is discovered that a utility owner has not provided a positive response, then the One-Call agency must be notified.

Excavation shall not be conducted until positive responses have been received from all utility owners identified by the One-Call agency as having underground utilities on the property.

Before beginning excavation, the excavator must verify that the location marked was correct, and the distinct, color-coded markings of all utility owners are present.

Examine the site to check for any visible signs of underground utilities that have not been located and marked such as pedestals, risers, meters, warning signs, manholes, pull boxes, valve boxes, ~

The markings placed by the utility owners must be documented by Tetra Tech using a still, digital, or video camera. The photo-documentation shall be maintained with the project files indefinitely.

The markings placed by the utility owners or marking services shall follow the American Public Works Association Uniform Color Code as described in ANSI Standard Z 535.1. This code appears below.

5.2.1.3 Private Utility Locating and Marking Services
As discussed, One-Call agencies arrange for the identification and marking of underground utilities only on public property, up to the point of contact with private property. In the event that excavation activities are to be conducted on non-public properties, the presence, location, depth, and orientation of all underground utilities within the white-lined area shall be ascertained through records review, including any site plot plans, utility layout plans, and as-built drawings available from the property owner, as well as through interviews with knowledgeable personnel associated with the property. Additionally, the information gathered from these sources shall be verified by physical detection methods (non-aggressive), performance of a geophysical survey, or by procuring ~

If any detection methods are to be self-performed, the requirements of 5.2.1.4 must be followed.

The above requirements are also intended to address the potential presence of unknown or undocumented underground utilities, therefore, the area to be excavated must also be evaluated by the PM to determine if the potential for unknown or undocumented underground utilities exist.

If the determination is made that the presence of these unknown or undocumented underground utilities is unlikely, then a variance should be requested to eliminate the requirement to identify them.

Variance to this requirement above must be approved by the PM and SSC.

5.2.1.4 Self-Performance of Utility Locating and Marking The techniques and instruments used to locate and characterize underground utilities can be extremely complicated and difficult to use effectively. Additionally, interpretation of the data generated by this instrumentation can be difficult. The utility marking services described in 5.2.1.1 and 5.2.1.2 are staffed by well-trained, experienced professionals who perform locating activities on a regular basis. For these reasons, it is most desirable that these professional services are used for utility location and marking on projects.

In some instances, such as long-term projects where excavation is a primary task, and the presence of underground utilities is extensive, it may be prudent to self-perform locating and marking activities.

If locating and marking is to be self-performed, all personnel using instrumentation will be trained on the use of the equipment that will be used, and the interpretation of the data.

There are a variety of locating methods which may be utilized for self-performance of utility locating as categorized below:
 Magnetic field-based locators or path tracers
 Buried electronic marker systems (EMS)
 Ground penetration radar-based buried –structure detectors  Acoustics-based plastic pipe locators

 Magnetic polyethylene pipe
Before self-performing any underground utility locating on a project, approval must be obtained from the Operating Unit Health and Safety Manager.

5.2.2 Working Near or Around Underground Utilities
After the site has been properly evaluated for the presence of underground utilities, intrusive activities may begin. Since there is no perfect way of eliminating the hazards presented by underground utilities, an effort must be made to perform the tasks following the direction and guidance as described by the following best practices that should be implemented during the execution of the project.

5.2.2.1 Work Site Review
Before beginning intrusive activities, a meeting shall be held between all members of the project team. This shall consist of a review of the marked utility locations with the equipment operators, observers, laborers, etc.

5.2.2.2 Preservation of Marks
During excavation, efforts must be made to preserve the markings placed by the utility owners until they are no longer required. If any markings are obliterated, the One-Call agency must be contacted for re-marking. No intrusive activities are to take place if markings are not visible.

5.2.2.3 Excavation Observer
Whenever intrusive operations are being conducted within four feet of the edge of the buffer zone, an observer must be assigned to monitor the activities. The observer will be designated each day, and a review of hand signals and other forms of communication between the observer and operator will be conducted. The directives of the observer will be followed precisely and immediately by those operating equipment.

Performing intrusive activities within the buffer zone requires careful adherence to proper guidelines and procedures to minimize the risk of contact with underground utilities.

The purpose of the buffer zone is to designate and define an area where careful, prudent, and reasonable excavation practices are to be used to prevent contact with underground utilities.

However, there may be occasions where it is necessary to perform aggressive excavation methods in this designated area.

The boundaries of the buffer zone as defined in Section 4.2 will be observed at all times during intrusive activities. Aggressive excavation methods (excavators, backhoes, drill rigs) must be restricted to areas outside of the 4-foot buffer zone unless a special exemption to this requirement is obtained.

Consider whether the objective of the project can be completed without performing intrusive activities in the buffer zone at all. This will greatly reduce the risks presented by performing work in close proximity to underground utilities. If after consideration, the determination is made that intrusive activities in the buffer zone are necessary, then a formal exemption request shall be made to the PESM according to the guidelines below.

A request to utilize aggressive excavation methods in the buffer zone may be made if:

There is no other appropriate and reasonable alternative to using aggressive methods in the buffer zone; and
 The utility has been de-energized (and purged if necessary), verified as de-energized, and locked-out (per Section 5.2.2.6); or
 the depth and orientation of the utility has been adequately and visually determined through the use of non-aggressive methods such as air/hydro/vacuum excavation, potholing, probing, hand-digging, or a combination thereof; and  for utilities containing electrical energy, the depth of the existing water table is below the location of the utility; and
 application for the exemption has been submitted to the SSC; and  the exemption has been granted and approved in writing by the SSC. ~

The following conditions will apply to this request:
 Aggressive methods may be used in the buffer zone only to the extent allowed by the applicable state or other jurisdictional regulations.
 Appropriate physical protection measures for exposed utilities as described in Section

5.2.2.5 shall be implemented to eliminate the potential for equipment contact with utilities.  The extent of the project excavation area to be covered by the exemption request must be specified.
 When evaluating the use of aggressive excavation methods in the buffer zone, the SSC will consider the type of utility involved and the associated risk potential.

Based on this evaluation, the SSC may impose further conditions and requirements, which will be detailed in the HASP.

Even if the above exemption conditions are met, the SSC has authority to deny the request, the reasons for which will be provided.

Unless exempted according to the above provisions of this procedure, only non-aggressive methods may be used within the buffer zone. Non-aggressive, or non-mechanized equipment is used in order to prevent mechanical contact with underground utilities which could result in damage to the utility and create the potential for personal injury and property damage. Following are examples of non-aggressive excavation methods:
 Hand-digging
 Non-conductive hand tools must be used when digging within the buffer zone surrounding underground electrical utilities.
 If conductive hand tools must be used near electrical lines, then the SSC shall be consulted to determine additional requirements relative to safe electrical practices, procedures, and equipment.
 Hydro-excavation (water pressure).
 Air excavation (air pressure).

 Air excavation/vacuum extraction combination.
 Aggressive methods may be used for the removal of pavement over a utility, if allowed by the state regulations.

5.2.2.5 Protection of Underground Utilities
It is very important that consideration be given to the protection of underground utilities when performing adjacent intrusive activities. This is necessary not only to prevent physical damage and associated indirect effects, but also to prevent the potential for injury to employees and the public.

When using aggressive excavation methods within the buffer zone around exposed underground utilities, physical protection may be appropriate. Basically, this involves creation of a physical barrier between the mechanized operation and the utility. The following are some possible types of physical protective measures:
 Heavy timbers, similar to swamp mats.
 Sheets of plywood.
 Blasting mats.
 Once exposed, underground utilities no longer have the support provided by surrounding soil and may need to be physically supported to prevent shifting, bending, separation, or collapse, which could result in damage to the utility, and possibly personnel. Following are suggested support methods:
 Timber shoring underneath the utility.
 Timbers or girders over the top of the excavation fitted with hangers that support the utility.  Design by a PE for complicated or large applications.  Utilities must also be protected from objects that may fall into the excavation such as rocks and equipment. This can be accomplished by following these guidelines:

Excavated and loose materials shall be kept two feet from the edge of excavations, as required by OSHA.  Relocate large rocks, cobbles, and boulders away from the excavation and sloped spoils piles.
 When vehicles and machinery are operating adjacent to excavations, warning systems such as soil berms, stop logs or barricades shall be utilized to prevent vehicles from entering the excavation or trench.
 Scaling or barricades shall be used to prevent rock and soils from falling into the excavation.
 Barriers shall be provided to prevent personnel from inadvertently falling into an excavation.

5.2.2.6 De-Energizing Utilities
Utilities can carry many types of potential energy, including electricity, flowing liquids, liquids under pressure, gasses under pressure, etc. A release, such as may happen if a utility conveyance is compromised, could result in personal injury, property damage, and other indirect effects. If the white lines of the proposed excavation area overlaps or extends into the buffer zone of a known underground utility, then if at all possible, that utility shall be de-energized to physically prevent the transmission, flow, or release of energy. Conversely, if the buffer zone of the known utility lies outside of the white-lined, proposed excavation area, then de-energization is not required.

The owner of the utility shall be contacted to determine the feasibility and methodology of deenergizing the utility. Plenty of lead-time should be provided for this since it may take utility companies weeks to de-energize some utilities.

Depending on the utility and the material being conveyed, isolation points which may be suitable for de-energizing include but are not limited to the following:
 Electrical circuit breakers
 Slide gate

 Piping flanges
 Other similar devices
When utilities are de-energized, it must be verified by demonstration. This can be accomplished by testing equipment, switching on a machine or lighting, opening a valve, etc. For any currentcarrying electrical equipment, such as cables, electrical panels, etc., successful de-energization must be certified through the use of appropriate electrical testing equipment.

Whenever a utility is de-energized, a means of ensuring that the energy isolation device and equipment cannot be operated until the device is removed must be provided. Typically, this is achieved by utilizing a lockout device, accompanied by a written tag that physically controls the configuration of the energy isolation point. Lockout devices include but are not limited to the following:
 Locks
 Chains
 Valve covers
 Circuit breaker hasps
 Blind flanges
 Slip blinds, and
 Multiple lock hasps
When de-energizing and locking out of utilities is practiced, the provisions of DCN 2-16 Control of Hazardous Energy Lockout/Tagout, shall be followed, as applicable.

In the event that a utility is de-energized, but there is no means of adequately providing a physical locking-out of the utility, then a spotter must be posted at the point of isolation to ensure that the utility is not re-energized. The spotter must be supplied with a communication device such as a site radio.

5.2.2.7 Damage Discovery
During excavation, utility damage may be discovered which is pre-existing or otherwise not related to a known contact. Disclosure to the utility owner is very important because the possibility of utility failure or endangerment of the surrounding population increases when damage has occurred. The utility may not immediately fail as a result of damage, but the utility owner or operator must be afforded the opportunity to inspect the utility and make a damage assessment and effect repairs if necessary. The following guidance applies:
 Observe and photograph the utility from a safe distance and determine in there is damage.

Damage would be all breaks, leaks, nicks, dents, gouges, grooves, or other damages to utility lines, conduits, coatings, or cathodic protection systems.  The One-Call agency or private location service must be contacted immediately.

5.2.3 Encountering or Contacting Underground Utilities
In the event that encountering or contacting an underground utility occurs, it is imperative that the appropriate actions are taken to minimize damage to the utility, prevent personal injury, and minimize indirect effects.

5.2.3.1 Encountering Underground Utilities
It is possible that underground utilities will be encountered in locations that have previously been “cleared” of having underground utilities by the locating service, or are found outside of the area which has been marked as having underground utilities. In either case, if this occurs, the following applies:
 Intrusive activities must be curtailed
 The One-Call agency or private location service must be contacted immediately  The PM and PESM must be notified
 No further intrusive activities may be conducted until:
 The One-Call agency/private location service and/or the subject utility owner visit the site; ~

 The orientation and depth of the subject utility has been determined and suitably marked.  A Tetra Tech Incident Report and Investigation form must be completed per DCN 2-2 Incident Reporting and Investigation Program. The report should be accompanied by photographs clearly showing the marking(s), and the actual location, with a distance gauge to document how far off the mark the utility was encountered.

5.2.3.2 Contacting Underground Utilities
If excavation or other equipment being used for intrusive activities makes contact with an underground utility, the following guidelines apply:
 Intrusive activities must be stopped immediately.
 Observe the utility from a safe distance and determine if there is damage. Damage would be all breaks, leaks, nicks, dents, gouges, grooves, scratched coatings, cathodic protection compromise, material leakage, obvious electrical energy.  Move all personnel to the evacuation meeting point as described in the SSHP.

EXCEPTION: If an electrical line has been contacted and it is your belief that equipment (such as an excavator) is electrically energized, do not approach the equipment. Order the operator to remain in the equipment until emergency personnel can de-energize the source (unless the equipment is on fire, at which time the operator should jump off of the vehicle and shuffle along the ground to a safe area). Shuffling is required because current flows outward through the soil in a ripple pattern called a power gradient, creating a pattern of high and low potential, Shuffling decreases the chance that these gradients could be bridged, causing current to flow through the body, resulting in electrocution.
 Secure the area to prevent the public from entering.
 Contact emergency responders as specified in the SSHP.  The One-Call agency or if known, the utility owner must be contacted immediately. ~

1.0 PURPOSE
Tt employees involved in remediation of spills or hazardous waste releases may be required to handle containers of hazardous waste. Services performed at hazardous and non-hazardous waste sites may also necessitate handling materials such as gasoline and oil for equipment operation, and chemicals for preservation of samples brought onto a site. Tt facilities may also maintain chemicals on-site in the construction materials engineering (CME) and analytical laboratories. These scenarios present the primary potential for spills or container leaks.

This safe work practice (SWP) addresses general guidance for spill prevention and cleanup.

Specific guidance for spill response can also be found in site-specific health and safety plans developed for hazardous waste sites, work plans for non-hazardous waste sites, the chemical hygiene plan, and the facility emergency response plan. Spill and discharge control practices should follow specific procedures to ensure the safety of responders and bystanders and to limit environmental impacts.

2.0 SPILL PREVENTION
The best spill response approach is to prevent spills from occurring. In order to achieve this, the following practices should be employed at Tt facilities and client job sites.  Make sure that all containers are appropriately labeled and that material safety data sheets (MSDS) are available. Before handling operating and analysis materials or hazardous waste, appropriate precautions should be in place to prevent spills and exposure to individuals.
 Store chemicals in appropriate locations. Make sure that incompatible chemicals are not stored in the same area. Refer to Appendix A for a general listing of incompatible chemicals.
 When transporting chemicals, ensure that the containers are properly closed, secured, and labeled. Do not carry more than one container at one time. If this is required, place containers within totes.
 Only keep the necessary quantity of each chemical on hand. For ease of use, keep chemicals in working containers that are appropriately sized for handling. ~

3.0 GENERAL SPILL RESPONSE PROTOCOLS
In the event that a spill does occur, the following general steps should be followed:
 The first concern should be for human health and safety. Tend to injuries immediately, evacuate the area if necessary, and alert appropriate response personnel.
 If the material is flammable or combustible, an attempt should be made to remove all sources of heat or ignition. However, this does NOT mean unplugging machinery; doing so may cause sparks.
 Consult the MSDS before spill cleanup activities to determine the proper PPE and cleanup equipment to be utilized.
 If the material is still spilling or leaking, attempt to stop additional spillage and contain the area to prevent spread of the contamination.  Cleanup should be conducted according to the proper techniques described in the MSDS, site-specific health and safety plan, and/or emergency response plan.  Cleanup should only be attempted by properly trained personnel wearing appropriate PPE.
 All waste should be disposed of according to applicable regulations.  IF THE SPILL IS TOO LARGE – CALL IN APPROPRIATE RESPONSE PERSONNEL. DO NOT ATTEMPT TO MANAGE THE SPILL YOURSELF.

4.0 DETAILED SPILL RESPONSE PROTOCOLS
This section provides more detailed steps to follow in the event of a spill or leak.

4.1 Immediate Actions
In the event of a spill, employees should immediately:
 Check for injured personnel.
 Clear the affected area.
 Contain the spill and isolate it, if it is safe to do so.  Contact the facility manager, project manager (PM) or site safety coordinator (SSC).

Immediate action should be taken to control and contain any spill following the general guidelines below:
 Unnecessary personnel should be kept away from the spill or discharge.  The hazardous area should be isolated.
 If the spill or discharge creates a hazardous situation or results in injury or an environmental release, the emergency procedures of the HASP should be implemented. Emergency response telephone numbers, designated contacts, and special reporting procedures are presented in the HASP.  Personnel should stay on the upwind side of the spill or discharge.  Entry into a confined space or low area where liquids or vapors may accumulate should be avoided.

 Drains, manholes, waterways, sewers, and the like should be identified and covered or protected.
 The spill should be controlled or absorbed using appropriate media or devices.  When the spill or discharge is fully contained and under control, spill or discharge material should be collected.
 Following cleanup, the spill area should be evaluated by collecting soil samples and screening the area with air monitoring instruments.

4.2 Decontamination of Personnel
If an individual is contaminated while handling or transporting hazardous materials, emergency response personnel must be notified and a spill team activated. The individual must also be decontaminated and receive medical attention. If decontamination procedures would cause further injury, decontamination should not be performed. Instead, use a blanket or other material to contain the contamination during transport, and inform emergency response personnel that the victim has not been decontaminated.

4.3 Risk Assessment
The risk assessment is based upon the hazards posed by the chemicals, the quantity of materials involved, and the location of the spill. A spill response leader should be designated if the spill warrants activation of a spill team (i.e., when a person is injured or contaminated, or a spill is beyond the control of the individual or site personnel). He/she is responsible for all aspects of the response until relieved by a qualified replacement. The spill response leader should determine the level of risk by answering the following questions:

4.3.1 What chemical is involved?
This may be determined by interviewing the person(s) who reported the spill and reviewing associated MSDS. Use knowledge of the work area and visual inspection to make a preliminary identification. This will be verified by direct inspection by the entry team.

4.3.2 How much has spilled?
Information gained when answering the question above should determine the quantity involved.

For a continuing leak, attempt to estimate the leak rate. If the quantity cannot be determined, you must assume release of the complete contents of the container.

4.3.3 Where is the incident located?
Take into account the relative area as well as the physical location. For example, determine where the spill is located relative to drains, water bodies, and other potential receptors.

4.4 Development of Spill Cleanup Plan
The spill response leader should develop a spill cleanup plan that includes the following elements:
 Ensure that safety is the number one priority and that all safety issues are addressed prior to beginning spill cleanup.
 Ensure that communication links between the spill response leader, members of the spill response team and emergency response personnel are in place.  Determine if the risk level associated with the spill allows for internal personnel to conduct the cleanup or if emergency response personnel should be summoned.  Determine the number of workers needed to safely and effectively perform the cleanup.

 Assign cleanup duties and responsibilities to the spill response team members.  Inform the appropriate facility manager, project manager, and client contacts.  Determine the required PPE to be worn by entry and backup spill team members and ensure that it is worn during the activities. Use the site health and safety plan contingency section or the facility emergency response plan to assist in this activity. Typical protective equipment may be Level C or D. In the event that the spill warrants a higher level of protection, Tt personnel should summon emergency response personnel.
 If the spill or discharge material is solid and nonreactive, the material should be scooped up and placed in a suitable and compatible container until the disposal method has been determined.
 If liquid is discharged, the following general procedures apply:
- The point of discharge should be immediately identified and measures taken to eliminate further discharges by uprighting or patching containers, transferring contents, or other appropriate methods.
- Any discharged liquids or sludge should be removed or retrieved. - Discharged materials should be cleaned up with absorbent materials or devices.
- Spent absorbent material should be placed into storage or disposal containers.  Determine proper equipment and spill control media to be used based on the chemical of concern. Typical equipment needed to accomplish spill cleanup may include:

 Open head 55-gallon drum with liner
 85-gallon salvage drum
 Control the area so that unnecessary personnel do not enter and situations that may escalate the hazards in the area are eliminated. Ideally, the exclusion zone should be physically barricaded off. At a minimum, barricade tape can be placed.  An exclusion zone, contamination reduction zone, and a support zone may be needed. Only authorized personnel will be allowed in these areas. Wind direction, plant and surrounding populations, and the properties of the spilled material must be considered in establishing the initial controlled zone. Exclusion zones should be barricaded (or at least taped off with barricade tape) to prevent general public access. The zone can be expanded or contracted as more information is gathered about the spill.
 Determine if the situation requires monitoring of explosive atmosphere, oxygen deficiency, or toxic levels of chemicals. This will also help determine the level of PPE required and conditions that would require the area to be evacuated and emergency response personnel summoned.

4.5 Implementation Spill Cleanup Plan
After the spill response leader has developed a plan to containerize and remove all material contaminated by the spill, the assigned members of the spill team will complete the following steps.

4.5.1 Cleanup, containerize, and decontaminate the area  Attempt to control the source of the leak if the full contents of a drum or container have not spilled. Perhaps the simplest procedure is to position the drum or container so that the leak is above the liquid level. Alternatively, a drum patch or plug can be applied to the leak. The leaking chemical may also be controlled using absorbent spill berms positioned around the drum or container.  Contain free-flowing liquids by diking or absorbing.
 Place all spill residues and cleanup equipment in an appropriate container.  If solvent is used to decontaminate equipment, floors, or walkways, appropriate fire protection should be used.
 Decontaminate and salvage as much equipment as possible.  Use only a final water wash where it is safe and appropriate to do so.

4.5.2 Analyze the affected area for proper decontamination safety  Use monitoring and detection equipment, if needed.
 Check equipment for problems.
 Examine walkways, floors, and stairs for obstructions or hazards (i.e. slip/fall exposure from liquid residue).
 Use any resources needed (safety, industrial hygiene, environmental, etc.) to ensure that the area has been decontaminated and is safe to re-enter.

4.5.3 Secure all response equipment
 Restock spill supplies.

4.5.4 Release site resumption of operations
 Notify operating personnel.
 Document spill or release in on-site or facility log.

As soon as the area is safe for reoccupancy, the spill response leader, in conjunction with the site or facility manager, must initiate actions to allow the facility to resume normal operations.  Use established procedures to announce an “All Clear.”  Properly mark spill residue containers for hazardous waste management.  Clean and prepare all emergency response materials for immediate use storage.  Complete all spill response reports as required.

5.0 FINAL TERMINATION OF THE INCIDENT
The project manager (PM) and site safety coordinator (SSC) should conduct a formal review and debriefing of the responders at the conclusion of the project. Corrective actions may need to be implemented if a cause for the spill was determined and can be prevented from happening again.

Final termination of the incident will be complete when the appropriate personnel review all reports and any corrective actions are completed.

6.0 REPORTING
In some instances, a release may require reporting to government agencies. If a reportable quantity is released (this quantity is stated on the Material Safety Data Sheet) or human health or the environment is threatened, appropriate national, state, and local administering agency personnel should be notified. The timeframe for notification may vary from agency to agency. ~

Notification may be required immediately or within 24 hours, depending on the type, location, and amount of released material. The appropriate agency to report spills to should be determined during HASP development.

All spills and chemical releases must be reported and investigated in accordance with Tt Program 2.1 Incident Reporting and Investigation. Details must be documented on the Forms IR and IR–B and entered into the Tetra Tech TOTAL system for appropriate incident review and tracking.

INCOMPATIBLE CHEMICALS
When certain hazardous chemicals are stored or mixed together, violent reactions may occur because the chemicals are incompatible (i.e., unsuitable for mixing). Classes of incompatible chemicals should be segregated according to hazard class during storage. Use the following general guidelines for hazard class storage.
 Flammable/combustible liquids and organic acids
 Flammable solids
 Mineral acids
 Caustics
 Oxidizers
 Perchloric acid
 Compressed gases
Separate hazardous chemicals in storage as follows:
 Oxidizing acids are segregated from organic acids, and flammable and combustible materials.

 Eye, foot and hearing protection devices shall be worn during pneumatic tool use.  Pneumatic tools shall be operated only by competent persons who have been trained in their use.  A pneumatic tool used where it may contact exposed live electrical parts shall have a nonconductive hose and an accumulator to collect moisture.  Employees shall not use any part of their bodies to locate or attempt to stop an air leak.

6.0 POWDER ACTUATED TOOLS
A powder actuated tool must always be treated the same as a loaded firearm. ALWAYS ASSUME THE TOOL IS LOADED. These tools come in both low and high velocity models, and both should have built-in safeguards; however, extreme caution must be used when working with this tool. Powder actuated tools can be used only by employees who have been trained in their operation. The user must have a current operator’s card.

The following checklist, which may not be complete for all scenarios, is required at a minimum before each use of a powder actuated tool. (Project Managers are responsible for identifying other site specific requirements.)
 Check the safety for proper operation and make sure the bore is clear.  Select the proper cartridge for the job to be done; never use a higher charge than is necessary.  Make sure that the drive part of the tool will not penetrate the mounting surface and fly out the other side. The work area must be backed up by a plank or beam.  Do not use this tool on hard steel, cast iron, rock, or other extremely hard materials.  Make sure no one else is in the immediate area; concrete chips, metal spalls or rebounding studs could injure bystanders. Insure protective shield is in place to confine flying fragments or particles when the tool is fired.
 Make sure the tool is at the correct angle to the work surface, and maintain pressure against the surface.
 Always wear proper eye and hearing protection.

INHALATION:

PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASED OF OVEREXPOSURE. RESCUE PERSONNEL SHOULD BE EQUIPPED THE SELF-CONTAINED BREATHING APPARATUS. Victims should be assisted to an uncontaminated area and inhale fresh air. Quick removal from the contaminated area is most important. If breathing has stopped administer artificial resuscitation and supplemental oxygen. Further treatment should be symptomatic and supportive. ___________________________________________________________________________

5. FIRE-FIGHTING MEASURES
These containers hold gas under pressure, with no liquid phase. If involved in a major fire, they should be sprayed with water to avoid pressure increases, otherwise pressures will rise and ultimately they may distort or burst to release the contents. The gases will not add significantly to the fire, but containers or fragments may be projected considerable distances - thereby hampering fire fighting efforts.
___________________________________________________________________________

6. ACCIDENTAL RELEASE MEASURES
In terms of weight, these containers hold very little contents, such that any accidental release by puncturing etc. will be of no practical concern.
___________________________________________________________________________

7. HANDLING AND STORAGE
Suck back of water into the container must be prevented. Do not allow backfeed into the container. Use only properly specified equipment which is suitable for this product, its supply pressure and temperature. Use only in well-ventilated areas. Do not heat cylinder by any means to increase rate of product from the cylinder. Do not allow the temperature where cylinders are stored to exceed 130oF (54oC).

Protection of firefighters
Specific hazards arising
from the chemical
Vapor may cause flash fire. Vapors can flow along surfaces to distant ignition source and flash back. Sensitive to static discharge.

Protective equipment and
precautions for firefighters
Wear full protective clothing, including helmet, self-contained positive pressure or pressure demand breathing apparatus, protective clothing and face mask.

Fire fighting
equipment/instructions
Wear full protective clothing, including helmet, self-contained positive pressure or pressure demand breathing apparatus, protective clothing and face mask. Withdraw immediately in case of rising sound from venting safety devices or any discoloration of tanks due to fire. Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Move containers from fire area if you can do it without risk. In the event of fire, cool tanks with water spray. Cool containers exposed to flames with water until well after the fire is out. For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn. Vapors may form explosive air mixtures even at room temperature. Prevent buildup of vapors or gases to explosive concentrations. Some of these materials, if spilled, may evaporate leaving a flammable residue. Water runoff can cause environmental damage. Use compatible foam to minimize vapor generation as needed.

Specific methods In the event of fire and/or explosion do not breathe fumes. Use water spray to cool unopened containers.

Hazardous combustion
products
Carbon monoxide. Carbon Dioxide. Sulfur oxides. Nitrogen oxides (NOx). Hydrocarbons.

6. Accidental Release Measures
Personal precautions Keep unnecessary personnel away. Local authorities should be advised if significant spills cannot be contained. Keep upwind. Keep out of low areas. Ventilate closed spaces before entering. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing.

See Section 8 of the MSDS for Personal Protective Equipment.

Environmental precautions Gasoline may contain oxygenated blend products (Ethanol, etc.) that are soluble in water and therefore precautions should be taken to protect surface and groundwater sources from contamination. If facility or operation has an "oil or hazardous substance contingency plan", activate its procedures. Stay upwind and away from spill. Wear appropriate protective equipment including respiratory protection as conditions warrant. Do not enter or stay in area unless monitoring indicates that it is safe to do so. Isolate hazard area and restrict entry to emergency crew. Extremely flammable. Review Firefighting Measures, Section 5, before proceeding with clean up. Keep all sources of ignition (flames, smoking, flares, etc.) and hot surfaces away from release. Contain spill in smallest possible area. Recover as much product as possible (e.g. by vacuuming). Stop leak if it can be done without risk. Use water spray to disperse vapors. Use compatible foam to minimize vapor generation as needed. Spilled material may be absorbed by an appropriate absorbent, and then handled in accordance with environmental regulations.

Prevent spilled material from entering sewers, storm drains, other unauthorized treatment or drainage systems and natural waterways. Contact fire authorities and appropriate federal, state and local agencies. If spill of any amount is made into or upon navigable waters, the contiguous zone, or adjoining shorelines, contact the National Response Center at 1-800-424-8802. For highway or railways spills, contact Chemtrec at 1-800-424-9300.

Methods for containment Eliminate all ignition sources (no smoking, flares, sparks, or flames in immediate area). Stop leak if you can do so without risk. This material is a water pollutant and should be prevented from contaminating soil or from entering sewage and drainage systems and bodies of water. Dike the spilled material, where this is possible. Prevent entry into waterways, sewers, basements or confined areas.

Methods for cleaning up Use non-sparking tools and explosion-proof equipment.

Small Spills: Absorb spill with vermiculite or other inert material, then place in a container for chemical waste. Clean surface thoroughly to remove residual contamination. This material and its container must be disposed of as hazardous waste.

Large Spills: Use a non-combustible material like vermiculite, sand or earth to soak up the product and place into a container for later disposal. Prevent product from entering drains. Do not allow material to contaminate ground water system. Should not be released into the environment.

Other information Clean up in accordance with all applicable regulations.

7. Handling and Storage
Handling Eliminate sources of ignition. Avoid spark promoters. Ground/bond container and equipment.

These alone may be insufficient to remove static electricity.

Wear personal protective equipment. Do not breathe dust/fume/gas/mist/vapors/spray. Avoid contact with eyes, skin, and clothing. Do not taste or swallow. Avoid prolonged exposure. Use only with adequate ventilation. Wash thoroughly after handling. The product is extremely flammable, and explosive vapor/air mixtures may be formed even at normal room temperatures.

DO NOT handle, store or open near an open flame, sources of heat or sources of ignition. Protect material from direct sunlight. Take precautionary measures against static discharges. All equipment used when handling the product must be grounded. Use non-sparking tools and explosion-proof equipment. When using, do not eat, drink or smoke. Avoid release to the environment.

Storage Flammable liquid storage. Do not handle or store near an open flame, heat or other sources of ignition. This material can accumulate static charge which may cause spark and become an ignition source. The pressure in sealed containers can increase under the influence of heat. Keep container tightly closed in a cool, well-ventilated place. Keep away from food, drink and animal feedingstuffs. Keep out of the reach of children.

Sensitization This substance may have a potential for sensitization which may provoke an allergic reaction among sensitive individuals.

Acute effects Harmful if inhaled, absorbed through skin, or swallowed. Harmful: may cause lung damage if swallowed. Irritating to eyes, respiratory system and skin. In high concentrations, vapors and spray mists are narcotic and may cause headache, fatigue, dizziness and nausea.

Local effects
US. ACGIH Threshold Limit Values
Benzene (CAS 71-43-2) Can be absorbed through the skin. n-Hexane (CAS 110-54-3) Can be absorbed through the skin.

Chronic effects Repeated exposure of laboratory animals to high concentrations of gasoline vapors has caused kidney damage and cancer in rats and cancer in mice. Gasoline was evaluated for genetic activity in assays using microbial cells, cultured mammalian cells and rat bone marrow cells. The results were all negative so gasoline was considered nonmutagenic under these conditions.

Overexposure to this product or its components has been suggested as a cause of liver abnormalities in laboratory animals and humans. Lifetime studies by the American Petroleum Institute have shown that kidney damage and kidney cancer can occur in male rats after prolonged inhalation exposures at elevated concentrations of total gasoline. Kidneys of mice and female rats were unaffected. The U.S. EPA Risk Assessment Forum has concluded that the male rat kidney tumor results are not relevant for humans. Total gasoline exposure also produced liver tumors in female mice only. The implication of these data for humans has not been determined.

Subchronic effects Subchronic inhalation of benzene by rats produced decreased white blood cell counts, decreased bone marrow cell activity, increased red blood cell activity and cataracts. Blood disorders may occur after prolonged inhalation, prolonged skin contact and/or ingestion. Liver and kidney damage may occur after prolonged and repeated exposure.

Carcinogenicity
ACGIH Carcinogens
Benzene (CAS 71-43-2) A1 Confirmed human carcinogen.

Ethanol (CAS 64-17-5) A3 Confirmed animal carcinogen with unknown relevance to humans.

Ethylbenzene (CAS 100-41-4) A3 Confirmed animal carcinogen with unknown relevance to humans.

Gasoline (CAS 86290-81-5) A3 Confirmed animal carcinogen with unknown relevance to humans.

Toluene (CAS 108-88-3) A4 Not classifiable as a human carcinogen.

US. OSHA Specifically Regulated Substances (29 CFR 1910.1001-1050) Benzene (CAS 71-43-2) Cancer hazard.

Epidemiology Contains benzene. Human epidemiology studies indicate that prolonged and/or repeated overexposure to benzene may cause damage to the blood-producing system and serious blood disorders, including leukemia. Animal tests suggest that prolonged and/or repeated overexposure to benzene may damage the embryo/fetus. The relevance of these animal studies to humans has not been fully established. Studies have shown a risk of spontaneous abortions in women exposed to high concentrations of organic solvents during pregnancy.

Mutagenicity In in-vitro experiments, neither benzene, toluene nor xylene changed the number of sister-chromatid exchanges (SCEs) or the number of chromosomal aberrations in human lymphocytes. However, toluene and xylene caused a significant cell growth inhibition which was not observed with benzene in the same concentrations. In in-vivo experiments, toluene changed the number of sister-chromatid exchanges (SCEs) in human lymphocytes. Toluene may cause heritable genetic damage.

Neurological effects Chronic exposure to high concentrations of various hydrocarbon blends may lead to polyneuropathy (peripheral nerve damage), characterized by progressive weakness and numbness in the extremities, loss of deep tendon reflexes and reduction of motor nerve conduction velocity. Numerous cases of polyneuritis have been reported following prolonged exposures to a petroleum fraction containing various isomers of heptane as major ingredients.

May cause central nervous system disorder (e.g., narcosis involving a loss of coordination, weakness, fatigue) and/or damage.

Reproductive effects Benzene, xylene and toluene have demonstrated animal effects of reproductive toxicity. Animal studies of benzene have shown testicular effects, alterations in reproductive cycles, chromosomal aberrations and embryo/fetotoxicity. Ethanol has demonstrated human effects of reproductive toxicity. May damage fertility or the unborn child. Can cause adverse reproductive effects - such as birth defects, miscarriages, or infertility. Avoid exposure to women during early pregnancy.

Avoid contact during pregnancy/while nursing.

Teratogenicity Abusive inhalation of toluene ("glue sniffing") has been reported to be associated with birth defects in the offspring of abusers. Rats exposed to benzene and xylene vapor during pregnancy showed embryo/fetotoxic effects. Ethanol has demonstrated human effects of teratogenicity.

Section 7. Handling and storage
Advice on general
occupational hygiene
Conditions for safe storage,
including any
incompatibilities
Eating, drinking and smoking should be prohibited in areas where this material is handled, stored and processed. Wash thoroughly after handling. Remove contaminated clothing and protective equipment before entering eating areas. See also Section 8 for additional information on hygiene measures.

Store in accordance with local regulations. Store in a segregated and approved area.

Store in original container protected from direct sunlight in a dry, cool and well-ventilated area, away from incompatible materials (see Section 10) and food and drink. Store locked up. Eliminate all ignition sources. Separate from oxidizing materials. Keep container tightly closed and sealed until ready for use. Store and use only in equipment/ containers designed for use with this product. Containers that have been opened must be carefully resealed and kept upright to prevent leakage. Do not store in unlabeled containers. Use appropriate containment to avoid environmental contamination.

Light hydrocarbon vapors can build up in the headspace of tanks. These can cause flammability/explosion hazards even at temperatures below the normal flash point (note:
flash point must not be regarded as a reliable indicator of the potential flammability of vapor in tank headspaces). Tank headspaces should always be regarded as potentially flammable and care should be taken to avoid static electrical discharge and all ignition sources during filling, ullaging and sampling from storage tanks. Do not enter storage tanks. If entry to vessels is necessary, follow permit to work procedures. Entry to any tanks or other confined space requires a full risk assessment and appropriate control measures to be put in place in conformance with appropriate regulations and industry practice on confined space entry. When the product is pumped (e.g. during filling, discharge or ullaging) and when sampling, there is a risk of static discharge. Ensure Protective measures Put on appropriate personal protective equipment (see Section 8). Do not get in eyes or on skin or clothing. Use only with adequate ventilation. Wear appropriate respirator when ventilation is inadequate. Avoid contact of spilled material and runoff with soil and surface waterways. Empty containers retain product residue and can be hazardous.

Keep in the original container or an approved alternative made from a compatible material, kept tightly closed when not in use. Do not reuse container. Store and use away from heat, sparks, open flame or any other ignition source. Use explosion-proof electrical (ventilating, lighting and material handling) equipment. Use only non-sparking tools. Do not breathe vapor or mist. Avoid exposure - obtain special instructions before use. Do not handle until all safety precautions have been read and understood. Do not swallow. Aspiration hazard if swallowed. Can enter lungs and cause damage. Never siphon by mouth.

Environmental exposure
controls
Emissions from ventilation or work process equipment should be checked to ensure they comply with the requirements of environmental protection legislation. In some cases, fume scrubbers, filters or engineering modifications to the process equipment will be necessary to reduce emissions to acceptable levels.

Appropriate engineering
controls
All activities involving chemicals should be assessed for their risks to health, to ensure exposures are adequately controlled. Personal protective equipment should only be considered after other forms of control measures (e.g. engineering controls) have been suitably evaluated. Personal protective equipment should conform to appropriate standards, be suitable for use, be kept in good condition and properly maintained.

Your supplier of personal protective equipment should be consulted for advice on selection and appropriate standards. For further information contact your national organisation for standards.

Provide exhaust ventilation or other engineering controls to keep the relevant airborne concentrations below their respective occupational exposure limits.

The final choice of protective equipment will depend upon a risk assessment. It is important to ensure that all items of personal protective equipment are compatible.

Wash hands, forearms and face thoroughly after handling chemical products, before eating, smoking and using the lavatory and at the end of the working period.

Appropriate techniques should be used to remove potentially contaminated clothing.

Wash contaminated clothing before reusing. Ensure that eyewash stations and safety showers are close to the workstation location.

Section 8. Exposure controls/personal protection
Hand protection
Use only with adequate ventilation. Do not breathe vapor or mist. If ventilation is inadequate, use a NIOSH certified respirator with an organic vapor cartridge and P95 particulate filter. If operating conditions cause high vapor concentrations or the TLV is exceeded, use supplied-air respirator.

CAUTION: The protection provided by air-purifying respirators is limited. Use a positive pressure air-supplied respirator if there is any potential for an uncontrolled release, if exposure levels are not known, or if concentrations exceed the protection limits of airpurifying respirator.

Use with adequate ventilation.

In case of insufficient ventilation, wear suitable respiratory equipment.

If there is a requirement for the use of a respiratory protective device, but the use of breathing apparatus (independent of ambient atmosphere) is not required, then a suitable filtering device must be worn.

The filter class must be suitable for the maximum contaminant concentration (gas/vapor/ aerosol/particulates) that may arise when handling the product.

The correct choice of respiratory protection depends upon the chemicals being handled, the conditions of work and use, and the condition of the respiratory equipment. Safety procedures should be developed for each intended application. Respiratory protection equipment should therefore be chosen in consultation with the supplier/manufacturer and with a full assessment of the working conditions.

Wear chemical resistant gloves. Recommended: Nitrile gloves.

Do not re-use gloves. Protective gloves must give suitable protection against mechanical risks (i.e. abrasion, blade cut and puncture). Protective gloves will deteriorate over time due to physical and chemical damage. Inspect and replace gloves on a regular basis. The frequency of replacement will depend upon the circumstances of use.

Respiratory protection
Body protection Use of protective clothing is good industrial practice. Cotton or polyester/cotton overalls will only provide protection against light superficial contamination that will not soak through to the skin. Overalls should be laundered on a regular basis. When the risk of skin exposure is high (e.g. when cleaning up spillages or if there is a risk of splashing) then chemical resistant aprons and/or impervious chemical suits and boots will be required. Wear suitable protective clothing. Footwear highly resistant to chemicals.

When there is a risk of ignition from static electricity, wear anti-static protective clothing.

For greatest effectiveness against static electricity, overalls, boots and gloves should all be anti-static. When there is a risk of ignition wear inherently fire resistant protective clothes and gloves. Work clothing / overalls should be laundered on a regular basis.

Laundering of contaminated work clothing should only be done by professional cleaners who have been told about the hazards of the contamination. Always keep contaminated work clothing away from uncontaminated work clothing and uncontaminated personal clothes. When the risk of skin exposure is high (from experience this could apply to the following tasks: cleaning work, maintenance and service, filling and transfer, taking samples and cleaning up spillages) then a chemical protective suit and boots will be required. Personal protective equipment for the body should be selected based on the task being performed and the risks involved and should be approved by a specialist before handling this product.

Other skin protection Appropriate footwear and any additional skin protection measures should be selected based on the task being performed and the risks involved and should be approved by a specialist before handling this product.

Consult your supervisor or Standard Operating Procedure (S.O.P) for special handling instructions.
