*%W 5..1 <br /> An initial work/rest cycle of one hour work and fifteen minutes rest is recommended <br /> for protection of the staff when the heat stress hazard is high. The recommended <br /> cycle will be adjusted up or down based upon worker monitoring, environmental <br /> conditions, and the judgement of the site safety officer. At any time field team <br /> members recognize the signs or symptoms of heat stress prior to a scheduled rest <br /> period, they will notify the SSO immediately in order that a rest period can be called. <br /> Heat stress, if not prevented, results in heat stress illnesses. Two critical illnesses, if <br /> not recognized and treated immediately, can become life threatening. These are heat <br /> exhaustion and heat stroke. Heat exhaustion will result if the prevention measures <br /> described above are not implemented. Ignoring the signs and symptoms of heat <br /> exhaustion will lead to the development of heat stroke. <br /> Heat stroke is an immediate, life-threatening condition that results because the body's <br /> heat regulating mechanisms shut down, and the body cannot cool itself sufficiently. <br /> As heat is excessively stored in the body, brain damage can result causing permanent <br /> disability or death. <br /> 4.2.4 Heat Exhaustion <br /> The signs and symptoms of heat exhaustion are headache; dizziness; nausea; <br /> weakness; fainting; profuse sweating; loss of appetite; approximately normal body <br /> temperature; dilated pupils; weak and rapid pulse; shallow and rapid breathing; <br /> possible cramps in abdomen and extremities; difficulty with walking; cool and sweaty <br /> skin to the touch: pale to ashen gray� colorings <br /> First aid for heat exhaustion is as follows: <br /> 1. Immediately remove the victim to the support area, or if you are the <br /> victim, proceed to the support area. <br /> 2. Decontaminate, if practical, before entering support area. <br /> 3. Start cooling, but be careful not to cause a chill (i.e., rest in the shade <br /> and apply a wet towel to the forehead; open up and/or remove clothing <br /> as much as practical, especially chemical-resistant clothing.) <br /> 4. Drink cool water slowly, but only if conscious, and not in shock. <br /> 5. If vomiting, and/or the signs and symptoms are not lessening within an <br /> hour, call for emergency help and/or transport the victim to the <br /> emergency room. <br /> 6. It is likely that a heat exhaustion victim will be unable to work for the <br /> remainder of the day. <br /> UK$C&&SKP <br /> 6.9.94/13 X1.00 4-3 <br />
