General Safety Instructions R2.8 CM2220 R101B Page i-12 Section i - Introduction Natural gas accumulates near the ceiling. Check the ceiling of the work area for ignition sources before servicing equipment. Only disconnect gas lines in a well-ventilated area. Do not troubleshoot or repair gas leaks while the engine is running. Natural gas ignition systems produce high voltage during operation. Do not touch ignition wiring or components while the engine is operating. If necessary, use only insulated tools. Natural gas exhaust systems operate at higher temperatures than similar diesel exhaust systems. Do not touch exhaust components.
Do not route lines or hoses which deteriorate from heat exposure near exhaust components or in the flow path of the exhaust. Always torque fittings and connections to the required specifications. over or under tightening can damage threads and create leaks. Liquefied Natural Gas Protect eyes. Protect skin. Always be alert for the smell of gas. Liquefied natural gas may not have an odor. Non-refined sources of natural gas (landfill gas, biogas, coal bed gas, wellhead gas, etc.) can not always be detected by smell. Always test for fuel leaks as instructed. Odorant can fade.
Upon entering a room or approaching a vehicle where the smell of gas is present, immediately shutoff all engines and ignition sources. Natural gas ignites when there is a 5% - 15% mixture in the air. Asphyxiation can occur when concentration reaches 21% or more. Do not start equipment or nearby equipment until a suspected gas leak is corrected and the area is ventilated. Avoid sparks, arcing switches and equipment, cigarettes, pilot lights, flames, and other sources of ignition. Work in areas that do not share common ventilation with areas containing ignition sources. Store and service natural gas fueled equipment in large, well-ventilated areas, or outside.
Provide extra ventilation to the work area. Natural gas accumulates near the ceiling. Check the ceiling of the work area for ignition sources before servicing equipment. Only disconnect gas lines in a well-ventilated area. Do not troubleshoot or repair gas leaks while the engine is running. Natural gas ignition systems produce high voltage during operation. Do not touch ignition wiring or components while the engine is operating. If necessary, use only insulated tools. Natural gas exhaust systems operate at higher temperatures than similar diesel exhaust systems. Do not touch exhaust components.
Do not route lines or hoses which deteriorate from heat exposure near exhaust components or in the flow path of the exhaust.. Liquefied natural gas is stored in vehicle tanks at extremely cold temperatures. If there is a liquefied natural gas spill, evacuate the area immediately and do not attempt to make contact with the liquid. Always torque fittings and connections to the required specifications. over or under tightening can damage threads and create leaks. Vapors accumulate near the floor. Check the work floor, sumps, and low lying areas for ignition sources before servicing equipment. Liquefied Petroleum Gas Protect eyes. Protect skin. Always be alert for the smell of gas.
Liquefied petroleum gas is typically treated with an odor producing chemical for leak detection. Always test for fuel leaks as instructed. Odorant can fade. Upon entering a room or approaching a vehicle where the smell of gas is present, immediately shutoff all engines and ignition sources.
