All 0 A Health and Safety Plan nnnnn Service Station # 000 S. J. WEAVER CONTRACTING zz%77 XXXXX. CA CCCCC 3.4.4 Heat Stress Heat stress may be a hazard for workers wearing protective clothing even if the temperature is moderate. The same protective clothing that shields the body from chemical exposure prevents heat and moisture from dissipating. Personal protective clothing can therefore create a hazardous condition. Depending on the ambient temperature and the work being performed, heat stress can occur very rapidly - within as little as 15 minutes. If an employee's pulse rate exceeds the maximum age adjusted heart rate (0.7(220 -AGE)), and / or oral temperature exceeds 100.4 ° F, the employee shall be required to stop work and rest or move to an air-conditioned room. The affected employee may be allowed to return to work after his / her pulse rate has dropped below 100 beats per minute. Fluids shall be provided and rest breaks will be taken. The frequency of breaks will increase with the temperature. Such things as cooling vests, portable fans and breaks in air-conditioned areas shall be used if necessary. 3.4.5 Noise Noise is found at construction sites in such operations as transportation and with heavy construction equipment. Noise has been defined as unwanted sounds. Hearing protection will be utilized by personnel operating or working around construction equipment or power tools. High noise operations will be performed at times that expose the fewest workers. Engineering controls will be utilized to reduce sound level reading to below acceptable levels. This may be performed by using barriers to isolate the operations or modifying the tool itself (muffler on jack hammers). 3.4.6 Electrical Overhead power lines, electrical wires, electrical fixtures, and buried cables all pose a danger of shock or electrocution if contacted or severed during site operations. A safe distance will be maintained between overhead wires. Electrical equipment used on site may also pose a hazard to workers. Whenever possible, low -voltage equipment with ground -fault interrupters and water -tight, corrosion -resistant connecting cables to minimize this hazard will be used. No employee shall be permitted to work in the proximity of any part of an electrical power circuit unless the person is protected against electric shock by de -energizing the circuit and grounding it, or it has been locked and tagged out. These procedures will be utilized when work has to be performed on energized equipment. All electrical wiring and equipment shall be intrinsically safe for use in potentially explosive environments and atmospheres. Ground fault interrupters shall be used in the absence of properly grounded circuitry or when portable tools must be used around wet areas. Prior to any intrusive activities at the site, S.J. Weaver Contracting Inc. will identify all utilities in the work area and protect them from damage. S.J. WEAVER CONTRACTING INC. Page 7 000-hasp.doc
