Safety Precautions

CNG systems should be maintained and inspected exclusively by trained personnel with certifications in accordance with the applicable codes. As with all pressure vessels, CNG storage and fuel delivery systems are inherently dangerous and should be treated as such. Individuals involved in any aspect of CNG fuel system maintenance, emergency response, servicing, or testing must be properly trained and certified. Individuals who are not trained and certified in all aspects concerning CNG fuel delivery systems are not permitted to service, maintain, test, or inspect a system in any way.

Follow these safety precautions when operating or repairing a natural gas vehicle.

• Only certified LNG personal can fuel LNG trucks.

• Do not start the engine if a natural gas leak is detected.

• Transferring fuel is only allowed as long as a non-static hose is used. if a non-approved hose is used, static can build up and ignite the fuel. A correct hose can be obtained through Agility fuel systems.

• Do not attempt to cut any fuel supply piping components.

• Avoid open flames or sparks near a natural gas vehicle.

• Cover eyes and exposed skin when working on a natural gas fuel system or fueling a natural gas vehicle.

• Permit no smoking or other ignition sources in, or within thirty feet of, a natural gas vehicle.

• Have CO₂fire extinguishers (ABC minimum) located in a highly visible and easily accessible location.

• Use Purple-K powder (PKP) or a similar dry powder to extinguish an LNG fire. Do not attempt use water around an LNG fire.

• Always purge the fuel lines before performing maintenance or repairs on a natural gas fuel system. Refer to the system manufacturer's service manual or the vehicle's workshop manuals for the proper purging procedure.

• Always use a natural gas detector to test the system for leaks, whether an odor is present or not. Routinely inspect the fuel filtering and regulating mechanisms, and the fuel lines. An approved natural gas bubble solution can be used to pinpoint the exact location of leaks. Do not use soap and water. Soap and water can cause premature failure of the O-rings in the system.

• Make sure black caps are always on the PRD vent lines to reduce water build up in lines.

• Do not store a natural gas vehicle indoors for any extended period of time. Do not bring a natural gas vehicle indoors unless the workshop is equipped with a methane detection and ventilation system.
