❑ If the tank has held fuel, or you have reason to believe that flammable liquids may be present in <br /> the work area, sample the work area with your combustible-gas indicator at several locations <br /> and record the results below. If you get a reading above 0% LEL, determine where the vapors <br /> are coming from before attempting to perform work. Do not perform work if the indicator reads <br /> above 10%LEL. Refer to Table 1 for more information on this subject <br /> Time of <br /> Day: <br /> Oxygen <br /> (%) <br /> Flammable <br /> Gas(iaLEL) <br /> Toxic Gas <br /> (PPM) <br /> Tester's <br /> Initials <br /> Physical Hazards — Evaluate the site for any physical hazards that you may encounter: <br /> ❑ Verify electric cords and lights are in good shape with no defects or exposed wires. <br /> ❑ If you will be working in very warm temperatures, plan your schedule so that you allow frequent, <br /> short rest breaks (out of direct sunlight if possible). Drink plenty of water. <br /> ❑ Be aware that heavy equipment operators may not always be able to see you. Plan your work <br /> so that you stay out of the path of this moving equipment. <br /> ❑ If the tank you will be working on Is buried, determine if the excavation has been properly sloped <br /> or shored. Refer to Appendix H, "Excavation Safety,"which contains detailed safety information <br /> for working around excavations. If the excavation does not look correct, immediately contact the <br /> site supervisor or the plant manager for assistance. <br /> ❑ Falls are one of the most common causes of injury at a jobsite. Refer to Appendix I, "Working at <br /> Elevated Heights—Fall Protection Supplement,"which contains detailed safety information on <br /> this subject. Keep your work areas organized and pick up debris that could become tripping <br /> hazards. <br /> Environmental Hazards —Weather can play a major role in field service work. <br /> ❑ Cease work activities at the approach of any electrical(lightning)storm. <br /> ❑ Determine what your plan will be if you are faced with snow, Ice, rain or extreme changes in <br /> temperature. <br /> ❑ Cleanup all debris generated at the site. Bring any waste that may-he considered hazardous <br /> back to the plant for proper disposal. <br /> I <br />
