i../ NATIONAL ADVERTISING CO:NIPANY— ADDITIONAL SURSURFACF. INVESTIGATION HEALTH AND SAFETY PLAN 6.0 ACTIVITY -SPECIFIC HEALTH AND SAFETY PROCEDURES The following safety procedures will apply to work operations as specified in the activity hazard analyses presented in Section 5.0. r� 6.1 SLIPS, TRIPS, FALLS, AND PROTRUDING OBJECTS Hazards from protruding objects, careless movements, or placement of materials on paths or foot traffic ... areas present a problem with regard to slips, trips, falls, and puncture wounds. Personnel will use a reasonable amount of effort to ensure the prevention of such injuries. 6.2 HAZARDOUS NOISE ENVIRONMENTS Working around large equipment often creates excessive noise. The effects of noise can include physical damage to the ear, pain, and temporary and/or permanent hearing loss. Workers can also be startled, annoyed, or distracted by noise during critical activities. Earth Tech has compiled noise monitoring data which indicates that work locations within 25 feet of operating heavy equipment (drill rigs, earthworking equipment, etc.) can result in exposure to hazardous levels of noise (levels greater than 90 dBA). Accordingly, all personnel are required to use hearing protection (ear plugs or ear muffs) within 25 feet to any operating piece of heavy equipment. The Health and Safety Professional may also monitor employee exposure to hazardous noise levels as part of Earth Tech's Hearing Conservation Program (see Section 7.2). 6.3 HEAVY MACHINERY The use of heavy machinery (drilling, trenching and digging equipment, cranes, etc.) in areas where unprotected personnel are operating warrants special attention on the part of all personnel. Operators should ensure that equipment is working properly and is being run in a safe manner, and should be aware of the location of unprotected personnel at all times while operating this machinery to avoid serious accidents. t� 6.4 EXPLOSIVE HAZARDS Intrusive work activities (e.g., drilling) increase the potential for the occurrence of elevated concentrations of volatile organic compounds that may be released. Explosive concentrations of these constituents could develop in small and confined spaces. Explosivity must be monitored with a Combustible Gas Indicator (CGI) in accordance with the requirements found in Section 7.1 (see Table 7-2). Flammable chemical compounds may not be identified and, therefore, any vapor or liquid must be treated as if it were flammable. to o.. Borehole installation activities will cease if concentrations exceed 10% of the Lower Explosive Limit (LEL), and personnel will withdraw to a position upwind of the affected area (see Table 7-2 for action guidelines).
