forehead; open up and/or remove clothing as much as practical, especially chemical -resistant <br />clothing). <br />3. Drink cool water slowly, but only if conscious and not in shock. <br />4. If vomiting and/or the signs and symptoms are not lessening within an hour, call for emergency <br />help and/or transport the victim to emergency room. <br />5. It is likely that a heat exhaustion victim will be unable to work for the remainder of the day. <br />Heat Stroke (aka sun stroke). The signs and symptoms of heat stroke are hot, dry skin to the touch; <br />reddish coloring; body temperature > 105 degrees F; no sweating; mental confusion; deep, rapid <br />breathing that sounds like snoring progressing to shallow, weak breathing; headache; dizziness; nausea; <br />vomiting; weakness; dry mouth; convulsions, muscular twitching, sudden collapse; possible <br />unconsciousness. <br />First aid for heat stroke is as follows: <br />1. Cool the victim rapidly using whatever means are available, including: shade; opening up and <br />/or removing clothing; soaking clothing/skin with water and fanning; placing victim in a vehicle <br />using air conditioning on maximum. <br />2. Do not give drinking water to victim. <br />3. Treat for shock, if needed. <br />4. Transport the victim to the emergency room or call for emergency help; no exceptions for heat <br />stroke victim. <br />Cold Stress. The potential for cold stress is a particular concern when field activities are performed while <br />air temperatures at the site are below 40 degrees F. If winds are blowing at 5 miles per hour (mph) or <br />greater and/or the weather is damp or wet, cold stress is even more of a potential hazard, Precautions <br />that will be taken t prevent cold stress include wearing cold protective clothing appropriate for the level <br />of cold and physical activity, changing under clothing if it becomes wet, and establishing a work/warming <br />regimen. Cold protective clothing will include layering of garment and use of love and hats. The <br />warming breaks should be taken in a warm location if at all possible, including improving a wind break <br />at the site. During warming breaks, warm sweet beverages and soups should be consumed to provide <br />calories and fluids. Drinking coffee or other decaffeinated beverages is not recommended. <br />Cold stress, if not prevented, can result in frostbite and hypothermia. Ignoring the sign and symptom so <br />cold stress can be life threatening. Prevention is the key. As a preventative measure, body core <br />temperature should not drop below 96.8 degrees F. Pain in the extremities is the first early warning of <br />cold stress. Sever shivering sets in when the body core temperature has dropped to 95 degrees F. If this <br />occurs,work will stop immediately and the affected worker(s) will take a warming break of sufficient <br />duration that the cold stress signs and symptoms are gone. <br />
