3.2.1.2 Heat Cramps <br /> Heavy sweating with inadequate electrolyte replacement causes heat cramps. Heat <br /> cramps can cause muscle spasms, and pain in the hands, feet, and abdomen. <br /> 3.2.1.3 Heat Exhaustion <br /> Heat exhaustion occurs from increased stress on various body organs including <br /> inadequate blood circulation due to cardiovascular insufficiency or dehydration. Heat exhaustion <br /> can cause cool,moist skin, heavy sweating, dizziness, and nausea and fainting. <br /> 3.2.1.4 Heat Stroke <br /> Heat stroke is the most serious form of heat stress. Temperature regulation fails and the <br /> body temperature rises to critical levels (>102). Immediate action must betaken to cool the body <br /> before serious injury and death occurs. Competent medical help must be obtained. Heatstroke <br /> `. can cause red, hot, unusually dry skin. Symptoms include lack of, or reduced perspiration, <br /> nausea, dizziness, confusion, and a strong rapid pulse and coma. <br /> 3.2.1.5 Heat Stress Monitoring Procedures <br /> During the day-to-day fieldwork, the Project Manager, Site Safety and Health Officer, <br /> and workers will be alert for the signs and symptoms of heat stress. An increased risk of this <br /> hazard exists when individuals are required to work in warm temperatures while wearing <br /> protective equipment. <br /> The Site Safety and Health Officer will monitor the ambient air temperature using a <br /> thermometer located in the support zone. Ambient temperatures will be checked three times <br /> daily, once in the morning and twice in the afternoon. Monitoring of all of the field <br /> crewmembers will be conducted when ambient temperatures exceed 85° F. <br /> 6 <br />
