HAZARD MITIGATORS — HEAT STRESS <br /> Applies to Task: N O O ❑ OO ❑ ® ❑ O ❑ S ❑ O ❑ S <br /> Prevention: <br /> • Drink plenty of hydrating fluids, such as Gatorade° or water. In high heat, a minimum of one <br /> gallon per day should be consumed. Fluid should be consumed frequently. Don't wait until <br /> thirsty. <br /> • Provide cooling devices, when necessary, to aid natural body heat exchange during prolonged <br /> work or severe heat exposure. Devices include field showers, hose-down areas, shade <br /> umbrellas/tents, wide-brim hats, and cooling jackets, vests,or suits. <br /> • If amenable to work conditions, wear light-colored, loose fitting, "breathable" clothing. <br /> • Avoid prolonged periods of exposure. Take breaks as necessary. Higher heat exposure <br /> requires more frequent breaks. <br /> • Be able to recognize the signs, symptoms and how to treat for heat stress. Signs, symptoms <br /> and treatment are listed below. <br /> Signs and Symptoms: <br /> • Mild heat stress -- Decreased energy, slight loss of appetite, nausea, lightheadedness. <br /> • Moderate heat stress - heavy sweating, thirst, faintness, headache, confusion. <br /> • Severe heat stress (heat stroke) - Throbbing headache, confusion, irritability, rapid heartbeat, <br /> difficulty breathing, dry skin (no sweating), vomiting, diarrhea. <br /> Treatment: <br /> • Mild and Moderate heat stress - Take to cool place, drink cool (not cold) fluids, remove <br /> excess clothing, rest. <br /> • Severe heat stress - Call 911 for an ambulance and get to a cool place, remove excess clothing <br /> and rest. <br /> • Adjust work and rest schedules as needed. Establish a work regimen that will provide <br /> adequate rest periods for cooling down. This may require additional shifts of workers. <br /> • Provide shelter or shaded areas (77°F is best)to protect personnel during rest periods. <br /> • Maintain worker's body fluids at normal levels to ensure that the cardiovascular system <br /> functions adequately. Daily fluid intake must equal the approximate amount of water lost <br /> Heat Stress(rev.24AugO6)-HazMit.doc.doc Page 1 of 2 8/3/2007 <br />
