The typical physical hazards present on the site and <br /> methods to prevent injury due to these hazards are described below. <br /> Heavy Equipment Operation <br /> The safety hazards associated with the operation of heavy equipment can be effectively <br /> eliminated by the employee if a constant awareness of these hazards is maintained. <br /> Constant visual or verbal contact with the equipment operator will facilitate such <br /> awareness. <br /> Sli . Trip & Fall Hazards <br /> While it is difficult to prevent slip-trip-fall hazards, risk of injury will be minimized by <br /> implementing proper site control measures such as daily safety meetings, proper footwear, <br /> and by keeping the work area free of obstructions. <br /> Lifting Hazards <br /> Field operations often require that heavy physical labor tasks be performed. All employees <br /> will be instructed in proper lifting techniques. Additionally, employees will be instructed to <br /> not attempt to lift large or heavy objects without assistance. <br /> Tool and Equipment Hazards <br /> Safety hazards present during the use of tools and equipment are generally associated <br /> with improper tool handling and inadequate maintenance. Management of these hazards <br /> involve rigorous maintenance of tools and equipment and effective training of employees <br /> in the proper use of these tools. <br /> Tank Removal <br /> The removal of underground storage tank presents two serious hazards: explosion of the <br /> tank and dropping the tank during removal from the excavation or loading onto the truck. <br /> Explosion will be prevented by removing as much combustible liquid as possible. Dry ice <br /> will be added at the rate of 20 pounds per 1,000 gallons capacity. All openings will be <br /> sealed with the exception of a 100 square-inch opening. Excavation, removal, and <br /> transportation of a tank will not be initiated until the lower explosion limit (LEL) reading is <br /> less than 10% and the oxygen reading is less than 8%. A worker may need to stand on the <br /> top of the tank, if it is safe, to take the measurements of the atmosphere inside the tank, <br /> and add dry ice to the tank, or to secure the tank prior to removal. Procedure for UST <br /> removal are included in Attachment 2. <br /> Open Excavation <br /> • Open excavations will be present during the UST removal at the project site. No personnel <br /> will enter the base of the excavation. Excavations will be maintained in compliance with <br /> C-8 <br />
