• The driller will not attempt to reach a well or borehole location in a manner that compromises the safety of the rig or crew. • All well or borehole locations will be inspected by the drill crew to ensure that a stable surface exists. • Before raising the drill mast, check for overhead obstructions. • Before the mast of a drill rig is raised, the drill rig must first be leveled and stabilized with leveling jacks and/or cribbing. Re-level the drill rig if it settles after initial set up. Lower the mast only when the leveling jacks are down, and do not raise the leveling jack pads until the mast is lowered completely. • The drill rig shall be driven or moved only after the mast has been lowered. • The leveling jacks shall not be raised until the derrick is lowered. • Adequately cover or protect all unattended boreholes to prevent drill rig personnel or site visitors from stepping or falling into the borehole. • Never allow "horsing around" within the vicinity of the drill rig and tool and supply storage areas - even when the drill rig is shut down. 6.1.23.2 Groundwater Monitoring This procedure establishes safe work practices and precautionary activities that must be followed to protect employees during groundwater monitoring activities. Groundwater monitoring, generally conducted on a quarterly basis, will consist of field sampling operations to collect water samples for subsequent analysis and evaluation of potential site contamination. The physical hazards of this operation are primarily associated with the sample collection methods and procedures utilized. Safety data sheets for the sample preservation chemicals are found in Appendix D. The primary hazards associated with these specific sampling procedures are not potentially serious; however, other operations in the area, or conditions in which samples must be collected, may present certain chemical, physical and biological hazards. The hazards associated with these types of sampling procedures include strains/sprains, uneven work surfaces, animals,ticks, and equipment handling. Chemical hazards are not anticipated but sampling personnel will wear surgical gloves as a precaution during water sampling operations. In addition to the safety hazards specific to sampling operations, hazards associated with the operation of vehicles, particularly large vehicles, in a small area will be a concern. Of particular concern will be the 6-16
