At 1 minute into the rest period, the recovery HR will be determined. The recovery HR should not exceed 110 beats per minute. 3. If the initial HR exceeds the age-adjusted maximum HR, or the 1 -minute recovery HR is greater than 110 beats per minute, then the next work period will be decreased by 10 minutes. Heat stress due to water loss can be prevented. To prevent dehydration, water must approximate sweat loss. Water intake guidelines are as follows: 1. The sense of thirst is not an adequate regulator of water replacement needs during heat exposure. Therefore, water must be replaced at prescribed intervals. a. Before work begins, drink two 8 -ounce glasses of water. b. During each rest period, drink at least two 8 -ounce glasses of water. 2. Plain water, served cool, is excellent. An adequate supply of potable water and drinking cups will be readily available, such as in a support vehicle, to provide water during rest periods. 3. Adding salt to water is not recommended. However, other fluids, in addition to water, could include dilute fruit juices and electrolyte replacement drinks diluted 3:1 with water. Do not use salt tablets! An initial work/rest cycle of 1 hour work and 15 minutes rest is recommended for protection of staff when the heat stress hazard is high. The recommended cycle will be adjusted up or down based upon worker monitoring, environmental conditions, and the judgement of the site safety officer. At any time, field team members recognize the signs or symptoms of heat stress prior to a scheduled rest period, they ill notify the SSO immediately in order that rest period can be called. Heat stress, if not prevented, results in heat stress illnesses. Two critical illnesses, if not recognized and treated immediately, can become life-threatening. These are heat exhaustion and heat stroke. Heat exhaustion will result if the prevention measures described above are not implemented. Ignoring the signs and symptoms of heat exhaustion will lead to the development of heat stroke, if unsafe condition persist. Heat stroke is an immediate, life threatening condition that results because the body's heat regulating mechanisms shut down, and the body cannot cool itself sufficiently. As heat is excessively stored in the body, brain damage can result causing permanent disability or death. Heat Exhaustion. The signs and symptoms of heat exhaustion are headache; dizziness; nausea; weakness; fainting; profuse sweating; loss of appetite; approximately normal body temperature; dilated pupils; weak and rapid pulse; shallow and rapid breathing; possible cramps in abdomen and extremities; possible vomiting, difficulty walking; cool and sweaty skin to the touch: pale to ashen gray coloring. First aid for heat exhaustion is as follows: 1. Immediately remove victim t the support area, or if you are the victim proceed to the support area. 2. Start cooling, but be careful not to cause a chill (i.e. rest in shade and apply wet towel to
