Health and Safety Plan for <br /> Delineation and Destruction of Well B-1 <br /> 3.1.10 Slips, Trips, and Falls <br /> Slips, trips, and falls may exist due to uneven terrain, wet or slick surfaces, leaks, or spills. <br /> Tripping and falling hazards may be present from elevation changes, debris, poor housekeeping <br /> or tools and environment. Some specific hazards may include an exposed excavation, well vaults <br /> and wet ground cover. Prevention requires attention and alertness on the part of each employee, <br /> following and enforcing proper procedures including good housekeeping practices, and wearing <br /> appropriate protective equipment. In addition, workers shall not enter areas that do not have <br /> adequate lighting. Additional portable lighting will be provided at the discretion of the Site <br /> Safety Officer or Project Manager, if necessary. <br /> 3.2 Chemical Hazards <br /> Exposure pathways of concern for chemical compounds that may be present at the site are <br /> inhalation of airborne contaminants, direct skin contact with contaminated materials, and <br /> incidental ingestion of affected media. Using proper protective equipment and following proper <br /> decontamination procedures can minimize dermal contact and incidental ingestion. To minimize <br /> inhalation hazards, dust or vapor control measures will be implemented, where necessary, and <br /> action levels will be observed during scheduled activities. <br /> Table I provides a summary of the physical properties of each potential site contaminant and the <br /> associated acute and chronic health effects resulting from exposure. <br /> 3.3 Electrical Hazards <br /> Electrical hazards can cause burns, shocks and death by electrocution. Never assume that a wire <br /> is safe to touch even if it is down or appears to be insulated. Maintain a distance of at least 10 <br /> feet when working near energized overhead lines. Never operate electrical equipment while <br /> standing in water. Use protective barriers or insulated materials when working near energized <br /> equipment. Always use caution when working near electricity. <br /> 3.3.1 Overhead Utilities <br /> Any overhead utility is considered to be energized unless and until the person owning or <br /> operating such line verifies that the line is not energized and the line is visibly grounded at the <br /> work site. If work is to be conducted in the vicinity of overhead electrical utilities, the <br /> appropriate distance shall be kept. <br /> 300V and Less Avoid contact <br /> 300V—750V 1 ft.(30.5 cm) <br /> 10275-4 <br /> D U D E K 10 June 2017 <br />
