HEAT EXHAUSTION./ f./ <br /> 'Heat exhaustion represents a somewhat more severe response to salt and <br /> water loss, as well as an initial disturbance in the body's heat- <br /> regulating system. Like heat cramps, heat exhaustion tends to occur in <br /> persons working in hot environments. Heat exhaustion is likely in <br /> dehydrated and hypertensive people. Untreated Heat Exhaustion may <br /> progress to Heat Stroke. <br /> Treatment of heat exhaustion is similar in principle to that of heat <br /> cramps. <br /> A. Signs and- Symptoms <br /> 1. Heat Exhaustion may come on suddenly as SYNCOPE and <br /> collapse, or it may be present with a headache, <br /> fatigue, dizziness, nausea with occasional abdominal <br /> cramping. <br /> 2. Sweating will be profuse. <br /> 3. Pulse rate will be rapid and weak. <br /> 4. Respiration rate will be rapid and shallow. <br /> 5. The skin will be pale and clammy. <br /> 6. The body temperature will be normal or decreased. <br /> 7. The worker could be irritable and restless. <br /> 8 . Monitor the worker's level of consciousness and airway. <br /> B. Emergency Care <br /> 1. Move the worker to a cool environment, take off as <br /> much of his clothing as possible, place him in a <br /> supine position with his legs elevated. <br /> 2. Sponge the worker with cool water. If you fan the <br /> worker, avoid chilling. When the body chills, the <br /> muscles generate energy. When the body shivers, <br /> this energy is released in the form of heat and <br /> actually can increase the body temperature. <br /> 3. If this is a true medical emergency, prompt <br /> intervention by Emergency Medical Services is <br /> recommended. <br /> 20 <br /> Site Safety 6 Health Plan Rev. /1. 0 <br /> October 20, 1997 <br />
