At the start of the first rest period, the worker will determine their HR. <br /> This initial HR should not exceed the individual's age-adjusted <br /> maximum HR, which equals [(0.7)(220 - age in years)]. At 1 minute <br /> into the rest period, the recovery HR will be determined. The recovery <br /> HR should not exceed 110 beats per minute. <br /> 3. If the initial HR exceeds the age-adjusted maximum HR, or the 1- <br /> minute recovery HR is greater than 110 beats per minute, then the next <br /> work period will be decreased by 10 minutes. <br /> Heat stress due to water loss can be prevented. To prevent dehydration, water intake <br /> must approximate sweat loss. Water intake guidelines are as follows: <br /> 1. The sense of thirst is not an adequate regulator of water replacement <br /> needs during heat exposure. Therefore, water must be replaced at <br /> prescribed intervals: <br /> a. Before work begins, drink two 8-ounce glasses of water. <br /> b. During each rest period, drink at least two 8-ounce <br /> glasses of water. ' <br /> 2. Plain water, served cool, is excellent. An adequate supply of potable <br /> water and drinking cups will be readily available, such as in a support <br /> vehicle, to provide water during resting periods. <br /> 3. Adding salt to water is not recommended. However, other fluids, in <br /> addition to water, could include dilute fruit juices and electrolyte <br /> replacement drinks diluted 3:1 with water. Do not use salt tablets! <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 4 <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 /> 42 <br />
