Safety and Health Plan Sandhu Property Tracy, California October 22, 2021 Terracon Project No. NA217074 8 7.0 Drilling Safety Precautions Project activities will consist of drilling three soil borings to 20 feet below grade surface (bgs), and nine shallow 1-foot soil borings. The 20 foot deep borings will be advanced by a track-mounted, direct push drill rig to maximum depths of 20 feet bgs, or refusal, whichever is encountered first. The personal protective equipment and direct-reading air monitoring requirements specified below are designed to prevent personnel exposure to contamination in excess of permissible exposure limits. Personnel must remain aware of the potential for fire if soils saturated with flammable liquids, such as gasoline, are encountered. 8.0 Site Physical Hazards/Precautions The physical hazards associated with intrusive site activities can include inclement weather, material handling, slips/falls etc. Some anticipated hazards and means for preventing injury from those hazards are as follows: •Back injuries due to improper lifting - Use proper lifting techniques. Lift with the legs, not the back. Keep loads close to the body and avoid twisting. Loads heavier than 50 pounds (lbs.) require a second person or mechanical device for lifting. Use mechanical devices such as drum dollies, hand trucks, and tool hoists (for lifting augers) to lift or move heavy loads whenever possible. •Ergonomic Stress - Lift carefully with load close to body with the legs taking most of the weight. Get help with lifts greater than 40 lbs. When working with a heavy tool or object, keep legs under the load and do not overreach or twist to the side. Reposition body to be more square to the load and work. Push loads, rather than pull, whenever feasible. Do not persist with lifting when the load is too heavy. Use a mechanical lifting aid or have a coworker assist with the lift. Rotate repetitive tasks to avoid soft-tissue fatigue. •Falls From Elevated Surfaces - Protect employees from falling off surfaces that have a side or an edge that is 6 ft. or more above a lower level. Provide a safety harness and shock-absorbing lifeline or adequate fall protection where applicable. Employees must wear them when working 6 ft. or higher above the platform or main work deck. Install either a guardrail system or fall arrest system that conforms to 29 CFR 1926.502 (d) and is approved by the American National Standards Institute. •Vehicles - Obey all site traffic signs and speed limits. Seat belts must be functional and in use during operation of any site vehicles (including rentals). Operator shall regularly inspect the vehicle for defective parts, such as brakes, controls, motor, chassis and drives. Always be aware and stay alert to traffic around the work area.
