Safety and Health Plan <br /> Premium California Orchards Tracy, California Irerracon <br /> January 8, 2021 Terracon Project No. NA207103 <br /> 18.2 THERMAL STRESS <br /> 18.3 Heat Stress <br /> Whenever ambient temperature exceeds 70 degrees F and personal protective equipment <br /> requirements are Level D or Level D modified, the following heat stress monitoring and preventive <br /> measures will be implemented: <br /> Mobilize at least one gallon of water for each field employee during each day of site <br /> activity. <br /> Periodically observe personnel for signs of heat stress (excessive perspiration, flushed <br /> skin, nausea, etc.). <br /> Move affected workers out of contaminant zones, <br /> Loosen protective clothing and permit them to rest <br /> Have conscious, affected personnel drink at least one 8 oz. glass of cool water. <br /> Check pulse; personnel should not return to work until pulse rate is less than 90 beats/min. <br /> Heat Stress in Level C/Level B PPE <br /> In addition to the above precautions, the following procedures will be implemented whenever the <br /> ambient temperature exceeds 701 F and personal protective equipment requirements are Level <br /> C or above. Ambient temperature will be measured with a dry bulb thermometer and percent cloud <br /> cover will be estimated: <br /> 1.0 = No Clouds <br /> 0.75 = 25% Clouds <br /> 0.5 = 50% Clouds <br /> 0.25 = 75% Clouds <br /> 0.0 = 100% Clouds). <br /> Calculate the adjusted temperature using the following formula: <br /> ADJUSTED TEMPERATURE = 13(% CLOUD COVER) + DRY TEMPERATURE <br /> Rest regimens will be implemented at frequencies dependent upon adjusted temperature. Monitor <br /> pulse during each rest period. <br /> 25 <br />
