rnvr vvinv uv+uain "". work activities will wear personal protective equipment and by the rate of work performed. Because the incidence of heat stress depends on a variety of factors, all workers will be monitored. b. Hazards associated with heat stress include the following: • Heat Rash - rosy result from continuous exposure to heat or humid air. • Heat Cramps- Caused by heavy sweating with inadequate electrolyte replacement. Heat cramps can cause muscle spasms, pain in the hands, feed and abdomen. • Heat Exhaustion- Occurs from increased stress on various body organs including inadequate blood circulation due to cardiovascular insufficiency or dehydration. Heat exhaustion can cause pale, cool, moist skin, heavy sweating, dizziness, nausea and fainting. • Heat Stroke- The most serious form of heat stress. Temperature ,regulation fails, and the body temperature rises to critical levels. Immediate action must be taken to cool the body before serious injury and death occur. Competent medical help must be obtained. Heat stroke can cause red,hot, unusually dry skin. Symptoms include: lack of or reduced perspiration, nausea, dimness, confusion and strong rapid pulse and coma. During the day-to-day field work, the Project Manager, Site Safety Officer and workers will be alert for the signs and symptoms of heat stress. A hazard exists when individuals are required to work in warm temperatures while wearing protective equipment. The Site Safety Officer will monitor the ambient air temperature utilizing local information sources. The field crew members working in chemical-resistant protective clothing will be observed for the following signs and symptoms of heat stress: dizziness and nausea, profuse sweating, skin color change,vision problems, fainting, weakness, fatigue, cramping, and hot, red, dry skin. Any team member who exhibits these symptoms will be monitored for heat stress. Heat stress monitoring will consist of measuring heart rate and/or body temperature (alternative)to prevent the onset of heat stress illness. Heart rate(HR)will be measured by the radial pulse of the wrist for thirty seconds as early as possible in the resting period. The HR at the beginning of the rest periods should not exceed 100 beats per minute. If the HR is in excess of the above guideline, the next work period will be shortened by one third, while the length of the rest period stays the same. If the pulse rate is in excess of 110 beats per minute at the beginning of the next rest period, the following work cycle will be further shortened by one third. Workers experiencing heat stress that is not relieved by rest period/work period modifications will be removed immediately from field work and be required, if conscious, to consume two to four pints of electrolyte fluid or cool water every hour while resting in a shaded area. The individual should not return to work until symptoms are no longer recognizable. If the symptoms
