eliminate this hazard, weather conditions should be monitored and work should be <br /> suspended during electrical storms. An additional electrical hazard involves capacitors <br /> that may retain a charge. All such items shoufld be properly grounded before handling. <br /> OSHA's standard 29 CFR Part 1910.137 describes clothing and equipment for protection <br /> against electrical hazards. <br /> 5.7 Heat Stress <br /> Heat stress is a major hazard, especially for workers wearing protective clothing. The <br /> same protective materials that shield the body from chemical exposure also limit the <br /> _ r <br /> dissipation of body heat and moisture. Personal protective clothing can therefore create a <br /> hazardous condition. Depending on the':_ ambient conditions 'and the work ; being <br /> performed, heat stress can occur very rapidly within as little as 15 minutes. it can pose as <br /> great a danger to worker health as chemical:;exposure. ' In its early stages, heat stress can <br /> cause rashes, cramps, discomfort and drowsiness, resulting in impaired functional ability <br /> that threatens the safety of both the individual,iand the coworkers. Continued heat stress <br /> can lead to heat stroke and death. Avoiding io,yerprotection, careful training and frequent <br /> monitoring of personnel who wear protective clothing, judicious scheduling of work and <br /> rest periods, and frequent replacement of fluids;can protect against this hazard. <br />' If temperatures exceed 70° F while protective coveralls are being worn, heat stress control <br /> measures shall be employed. Bottled water'will be available on site for consumption to <br /> replace body fluids. Personnel will take breaks and rest in shaded areas. Physical activity <br /> will be minimized. <br /> 5.8 Cold Exposure <br /> Cold injury (frostbite and hypothermia) and'irlipaired ability to work are dangers at low <br /> temperatures and when the wind-chill factor: is low. To guard against them: wear <br /> appropriate clothing; have warm shelter readily available; carefully schedule work and <br /> rest periods, and monitor workers' conditions. <br /> k <br /> I, S:\13FS\ST0CKT0N\HSP0011 10/15/99 5-9 <br />
