Morita Brothers Service Station 13 July 16, 1992 <br /> t � <br /> Sunburn <br /> Working outdoors on sunny days for extended periods of time can cause sunburn to <br /> the skin Excessive exposure to sunlight is associated with the development of skin <br /> icancer Field staff should take precautions to prevent sunburn by using sun-screen <br /> lotion and/or wearing hats and long-sleeved garments <br /> Feat Stress <br /> Heat stress can be a major hazard, especially for workers donning personnel <br /> protective equipment (PPE) The same protective materials that shield the body from <br /> chemical exposure also limit the dissipation of body heat and moisture Heat stress <br /> can occur very quickly, depending on the work being, performed, the ambient <br /> weather conditions, clothing, and the individual characteristics of the worker <br /> Because heat stress is probably one of the most common (and potentially serious) <br /> illness at hazardous waste sites, regular monitoring and other preventive <br /> precautions are vital <br /> Heat stress monitoring should commence when personnel are wearing PPE, <br /> including Tyvek-type coveralls, and the ambient temperature exceeds 70°F If <br /> impermeable garments are not worn, monitoring should start when the temperature <br /> reaches 85°F The following monitoring program is for workers wearing <br /> semipermeable or impermeable encapsulating ensembles when the temperature in <br /> the work area is above 70°F <br /> Heart Rate should be measured by the radial pulse during a 30 second period as <br /> early as possible in the rest period The next work cycle should be shortened <br /> by one-third while the rest period is kept the same, if the heart rate exceeds <br /> 110 beats per minute If the heart rate still exceeds 110 beats per minute at the <br /> ' beginning of the next rest period, shorten the following work cycle by one- <br /> third <br /> Preventing heat stress is particularly important because once someone suffers from <br /> heat stroke or heat exhaustion, that person may be predisposed to additional heat <br /> injuries To avoid heat stress, the following steps may be taken <br /> - Modify work/rest schedules according to monitoring requirements, and <br /> mandate slowdowns as needed <br /> ' EB-8101-3 9207-EO37 WP <br />
