5.0 JOB HAZARD ANALIYSIS <br /> � F <br /> Previous investigations indicate that gasoline and waste oil related <br /> i <br /> compounds are the contaminants of concern at the project site. <br /> Physical hazards at this work site includie those associated with: <br /> o heat stress; <br /> 1 LEo slip-trip-fall type of accidents; <br /> o back injuries due to improper lifting; <br /> o being caught in or struck by moving' equipment; <br /> o electrocution or explosion hazards associated with drilling or <br /> r <br /> j excavation activities, such as contact with overhead or underground <br /> power lines or pipelines. <br /> 5.1 HEAT STRESS RECOGNITION AND CONTROL ` <br /> I i <br /> The wearing of Personal Protective Equipment (PPE) can place a hazardous <br />!i waste worker at considerable risk of developing heat stress. This can result in <br /> health effects ranging from transient heat fatigue to serious illness or death. <br /> Heat stress is caused by a number of interacting factors, including environmental <br /> conditions, clothing, work load, and the individual characteristics of the <br /> worker. Because heat stress is probably one of the most common (and potentially <br /> serious) illnesses at hazardous waste sites, l regular monitoring and other <br /> preventive 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 /> standard work garments (cotton coveralls) are worn, monitoring should commence <br /> at 85°F. Heat stress monitoring and control , guidance can be found in the <br /> _ Attachments. <br /> r ' 5.2 CHEMICAL HAZARDS <br /> From an occupational health standpoint, given that any potential exposure <br /> to site personnel will be only for a short period of time (intermittent for <br /> several days) , the levels of contaminants, <br /> detected by previous site <br /> investigations should not represent a significant concern. However, the site is <br /> still under investigation, so the potential foriexposure to elevated levels of <br /> these contaminants may exist.
