Ensure that emergency telephone numbers are site specific, readily available, easily read, and communicated to all employees.
Train and authorize employees to implement emergency procedures.
Medical
Emergencies
Have procedures and medical supplies to provide emergency medical services for your own personnel.
Determine how to contact emergency medical services before work begins, and have on-site capabilities to contact such services immediately.
Fires See Fire Protection above.
In the event of a fire, you must:
- Immediately remove personnel from the area or building following City evacuation procedures.
- Immediately contact the nearest City employee and inform him or her of the fire. You may also activate an emergency alarm in the area. If no City employees are on-site, immediately contact the local fire department.
Personnel trained in the use and limitations of fire extinguishers may attempt to extinguish the fire if it is safe to do so.
Chemical Releases See Hazardous Materials above.
If the event of a hazardous material release, you must:
- Immediately remove personnel from the area or building following City evacuation procedures.
- Immediately contact the designated City representative and inform him or her of the release. You may also activate an emergency alarm in the area. If no City employees are on-site, immediately contact the local fire department.
Contractor personnel should not respond to the release unless specifically trained and protected to perform hazardous material response.
Power Outages In the event of a power outage, you must:
- Immediately stop work and assemble for a head count and possible facility egress.
- Inform all contract employees that equipment may automatically restart when power resumes.
- Immediately contact the designated City representative and inform him or her of the status of contract work and personnel head count.
Relay at this time all hazards created due to the power outage.
When power resumes evaluate the status of operations that were being performed relative to hazard potential. For example, the interruption of ventilation in confined spaces may generate atmospheric hazards.

MONTEBELLO SENIOR CENTER 03 3000 - 20
REMODEL
5) Addition of water to the surface during the finishing operation. 6) Use of the floor during construction in a manner that leads to marring or staining the finish.

The finish surface shall match that of the adjacent existing concrete.
As soon as the moisture sheen has disappeared from the floated surface and the concrete has hardened sufficiently to prevent drawing moisture and fine materials to the surface, the surface shall be steel troweled to produce a smooth, hard, uniform finish. Final steel troweling shall be conducted after the concrete is hard enough that no mortar accumulates on the trowel when manipulated with heavy pressure. Machine finishing may be used for troweling.
d. Exposed concrete slabs shall be sealed or sealed and hardened using a liquid compound compatible with the curing method used as described in 3.7 Curing, Protection, Liquid Hardeners and Sealers of this Section.
3.6 CURING, PROTECTION, LIQUID HARDENERS AND SEALERS
A. Curing Compound
1. All curing methods shall be placed immediately after final finishing (i.e., within two hours). Contractor's attention is directed to the fact that experience shows the most important time of curing is from three to four hours after placing and extending five to six hours thereafter. It is extremely important, therefore, to prevent loss of moisture, particularly during this period when concrete is especially vulnerable to plastic shrinkage cracks.
All exposed surfaces of concrete including floor slabs, whether or not they receive a finish flooring, shall be protected from premature drying for a minimum of seven days.
2. Apply the specified curing compound in strict accordance with manufacturer’s written instructions. Curing compound shall not be diluted by the addition of solvents or thinners, nor shall it be altered in any other manner. Curing compound that has become chilled and is too viscous for satisfactory application shall be heated by steam or hot water bath until it has proper fluidity. The temperature of the compound shall not exceed 100
SECTION 03 3000
CAST-IN-PLACE CONCRETE
MONTEBELLO SENIOR CENTER 03 3000 - 21
REMODEL
ºF. Curing compound shall not be heated by direct exposure of the container to fire.
3. When used on an unformed concrete surface, application of the first coat of curing compound shall commence immediately after finishing operations have been completed. When curing compound is used on a formed concrete surface, the surface shall first be moistened with a fine spray of water immediately after the forms have been removed. The spray shall be continued until the surface does not readily absorb further water. As soon as the surface film of water has disappeared and the surface is almost dry, the first coat of curing compound shall be applied. In the event that application is delayed on either formed or unformed surfaces, the surface shall be kept continuously moist until the compound has been applied or the specified period of water curing has elapsed.
4. Surfaces shall be sprayed uniformly with 2 coats of curing compound. Each coat shall provide a minimum coverage of 1 gallon per 250 square feet of surface. As soon as the first coat has become dry, a second coat shall be applied in the same manner. The direction of application of the second coat shall be perpendicular to the first coat. The curing compound shall be sprayed using approved pneumatic or pump driven equipment having the following characteristics:
a. Separate lines to the nozzle for material and for compressed air b. A filtering system for the removal or entrapment of contaminants c. A constant application pressure
5. Curing compound shall not be used on any concrete surface specified to receive additional concrete, coatings, grout, and chemical treatment B. Protection
1. The contractor shall allow no traffic and take precautions to avoid damage to the membrane of the curing compound for a period of not less than 28 days. Damage shall be repaired immediately to the satisfaction of the Engineer.
2. Special care shall be taken to prevent damaging the surfaces and joints due to load stresses from construction equipment, heavy shock, and excessive vibration. During construction activities, concrete shall be protected against damage with plywood or other approved materials until final acceptance by the Engineer.
C. All floor slabs shall be cured using products and methods compatible with selected floor adhesives, toppings, and other finish materials.
D. Sealing Coat: Uniformly apply a continuous sealing coat of curing and sealing compound to hardened concrete by power spray or roller according to manufacturer’s written instruction.

C. Do not patch, fill, touch-up, repair, or replace exposed concrete except upon express direction of City Engineer for each individual area. Should the City Engineer grant permission for the Contractor to attempt restoration of a defective area by patching or other repair methods, such permission shall not be considered a waiver of the Engineer’s right to require complete removal of the defective area if, in the Engineer’s opinion, the restoration does not provide the structural or aesthetic integrity of the member or members.
D. All repairs of defective areas shall conform to ACI 301. On areas requiring treatment of defects and until such repairs have been completed, only water cure will be permitted.

C. Gently scrub the floor using red or maroon cleaning, not stripping pads, mounted on a single disc, 175 RPM floor machine; or preferably, with a machine that uses horizontally mounted brushes with a counter-rotating spindle motion. Never allow the machine to remain running stationary.
D. Remove the resulting slurry with a wet vacuum.
E. Rinse the floor at least four times, each time using a clean mop and clean rinse water. On the first rinse, apply just enough water to keep the floor wet until the solution is picked-up with a vacuum. The next two rinses should be with a fairly well wrung-out, damp mop. The final rinse should produce virtually clean rinse water. Ensure the rinse water is clean throughout the rinsing process. Avoid tracking the floor after the final rinse. Check the floor after the final rinse for any missed areas and re-scrub/rinse as needed.
Repeat the rinsing process until all signs of the cleaning solution are removed and the floor shows no sign of haziness or dusting when dry. If the Contractor has lightweight “automatic” floor machines capable of achieving the same result as described above, they may be used in-place of this method. Do not flood or excessively dampen floor at any time.
F. Allow the Work to dry thoroughly.
