R2.8 CM2220 R101B General Safety Instructions Section i - Introduction Page i-13 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. Liquefied petroluem gas accumulates near the floor. Check the work floor, sumps, and low lying areas 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. Liquefied petroleum 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. Liquefied petroleum 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. Power Generation Applications Follow these recommended practices when interacting with equipment in generator set applications. Power generation applications produce high voltage during operation. When servicing a generator set, the following safety precautions must be taken. Remove any debris from the generator set.
Keep the floor clean and dry throughout servicing Service access doors must be secured in the "open" position before working on enclosed generator sets. Use insulated or non-conducting tools. Prevent accidental or remote starting. Disconnect the starting battery cables. Disconnect the negative ( - ) terminal first. Isolate all auxiliary supplies. Switch the generator set control panel "off." Place a "Do Not Operate" tag on the control panel. Lock the generator set circuit breaker in the "Open" position. Activate the manual "Emergency Stop" device. Do not step on the generator set when servicing, entering, or leaving the generator room.
Aftertreatment Follow these recommended practices when interacting with equipment that utilize aftertreatment systems. For information regarding proper handling of various substances, refer to the manufacturer's safety data sheet. Diesel Exhaust Fluid Avoid breathing vapor or mist. Protect eyes. In case of contact with eyes, flush with water for a minimum of 15 minutes. Protect skin. In case of contact with skin, wash with soap and water. Diesel Particulate Filter Do not ingest. If ingested, contact a physician immediately. Protect eyes. Protect skin. To buy Cummins Parts and Service Manuals, Training Guides, or Tools go to our website at https://store.cummins.com
