Health and Safety Plan July 18, 1994 <br /> Law/Crandall Project Golden Final <br /> 4.0 PHYSICAL AND HEALTH HAZARDS <br /> The following section details the potential safety and health hazards which may be encountered <br /> during the drilling and sampling of subsurface soils. <br /> 4.1 Physical Hazards <br /> Anticipated physical hazards include exposure to noise from site equipment; operation of heavy <br /> equipment; heat stress; underground utilities; and other hazards associated with any outdoor labors <br /> such as slips, trips, falls and material-handling (back) injuries. <br /> 4.1.1 Drilling Operations <br /> Physical hazards are associated with subsurface drilling operations and the use of heavy equipment. <br /> Both above and below ground utility lines present a potential for electrocution if contacted by <br /> drilling equipment. Utilities and other subsurface obstructions must be located before soil borings <br /> are drilled. The Project Manager is responsible for securing utility clearances. The driller must <br /> maintain a safe clearance distance (normally 25 feet) between overhead utility lines and the drill <br /> rig. <br /> Drilling activities involve a number of potential injury hazards including, but not limited to the <br /> following: <br /> • Injuries from flying debris, being caught up in machinery, hydraulic <br /> failures, unguarded points of operation, air-borne particulates, equipment <br /> rollover and other hazards associated with the transportation and use of <br /> drill rigs. <br /> • Injuries from extremely loud noises associated with the operation of the <br /> drill rig. <br /> To protect site personnel, hard hats, steel-toed boots, safety glasses and hearing protection are <br /> mandatory in the vicinity of the drill rig. The following steps will be followed to help minimize <br /> accidents and injuries associated with drilling: <br /> 5 <br />
