LMark& Brothers Service Sft on 1 1 March 7, 1942 <br /> L � <br /> L <br /> Preventing heat stress is particularly important because once someone suffers from <br /> Lheat stroke or heat exhaustion, that person may be predisposed to additional heat <br /> injuries. To avoid heat stress, the following steps may be taken: <br /> • Modify work/rest schedules according to monitoring requirements, and <br /> mandate slowdowns as needed. <br /> • Alternate personnel assigned to particular tasks to minimize over stress at <br /> one job function. <br /> L • Add additional persons to work team, and work during cooler hours, if <br /> possible. <br /> • Provide shelter or shaded areas to protect personnel during rest periods. <br /> • Maintain workers body fluids to ensure that the cardiovascular system <br /> L functions adequately by having workers drink 16 ounces of fluid <br /> (preferably water) before beginning work, and urge workers to drink at <br /> least 16 ounces of fluid during each rest period. <br /> • Encourage workers to maintain an optimal level of physical fitness. <br /> An initial work/rest cycle on one hour work and fifteen minutes rest is <br /> t„ recommended for protection of staff when the heat stress hazard is high. The <br /> recommended cycle will be adjusted up or down based upon worker monitoring, <br /> environmental conditions, and the judgement of the site safety officer. At any time <br /> field team members recognize the signs or symptoms of heat stress prior to a <br /> Lscheduled rest period, they will notify the site safety officer immediately in order <br /> that a rest period can be called <br /> Some of the signs and symptoms of heat stress are heat rash, heat cramps, heat <br /> exhaustion, and heat stroke. Heat rash is characterized by a decreasing ability to <br /> �. tolerate heat and skin irritation and may result from exposure to heat or humid air. <br /> Skin cleanliness and treatment with mild drying lotions are necessary to prevent <br /> infection. Meat cramps are caused by heavy sweating with inadequate electrolyte <br /> replacement and are characterized by muscle spasms and pain in the hands, feet, and <br /> abdomen Treatment of this disability consists of administering salted liquids orally. <br /> L <br /> LEB-8101-1 9203-E016.WP <br /> k <br />
