UNITED PARCEL SERVICE <br /> Site Safety Plan <br /> October 7, 1991 <br /> Heat Stress Prevention <br /> A. Replace body fluids (water and electrolytes) lost through <br /> perspiration. Solutions may include a 0. 1% salt and water <br /> solution or commercial mixes such as Gatorade and Squench. <br /> B. Cooling devices to aid the natural body ventilation. <br /> Cooling occurs through evaporation of perspiration and <br /> limited body contact with heat-absorbing protective <br /> clothing. Utilize fans and air conditioners to assist in <br /> evaporation. Long, cotton underwear is suggested to <br /> absorb perspiration and limit any contact with heat- <br /> absorbing protective clothing (i.e. , coated Tyvek suits) . <br /> C. Provide hose-down mobile shower facilities to cool <br /> protective clothing and reduce body temperature. <br /> D. Conduct non-emergency response activities in the early <br /> morning or evening during very hot weather. <br /> E. Provide shelter against heat and direct sunlight to <br /> protect personnel. <br /> 4 F. Rotate workers wearing protective clothing during hot <br /> weather. <br /> 1 Exposure -- Cold Stress: <br /> Work schedules will be adjusted to provide sufficient rest <br /> periods in a heated area for warming up during operations <br /> conducted in cold weather. Also thermal protective clothing <br /> such as wind and/or moisture resistant outerwear is recommended <br /> to be worn. <br /> if work is performed continuously in the cold at or below -7°C <br /> (201,F) , including wind chill temperature, heated warming <br /> shelters (tents, cabins, company vehicles, rest rooms, etc. ) <br /> shall be made available nearby and the worker should be <br /> encouraged to use these shelters at regular intervals the <br /> frequency depending on the severity of the environmental <br /> exposure. The onset of heavy shivering, frostnip, the feeling <br /> of excessive fatigue, drowsiness, irritability, or euphoria, <br /> are indications for immediate return to the shelter. When <br /> entering the heated shelter the outer layer of clothing shall <br /> be removed and the remainder of the clothing loosened to permit <br /> sweat evaporation. A change of dry work clothing shall be <br /> provided as necessary to prevent worker from returning to their <br /> work with wet clothing. Dehydration, or the loss of body <br /> fluids, occurs in the cold environment and may increase the <br /> 9 <br />
