Individuals involved in any aspect of CNG fuel system maintenance, emergency
response, servicing or testing must be properly trained. Individuals who are not
trained are not permitted to service, maintain, test, or inspect a system.
Observe all recommendations below when operating or servicing a CNG fuel system.
1. CNG safety signage should be visible at all applicable locations as stipulated by federal, state, and municipal
law.
2. Natural gas rated fire extinguishers should be accessible and visible throughout all servicing and fueling areas.
Verify fire extinguishers are charged, up to date, and rated correctly.
3. In case of emergency, self-contained breathing apparatus should be on site in an easily accessible area.
4. Areas designated for CNG fueling systems must have adequate lighting that complies with NFPA code.
5. Protective eyewear and footwear should be worn by all personnel near a CNG system.
6. When locating the source of a leak only use certified leak detecting solutions such as Swagelok Snoop
®
or
Formula 365 ( p/n 10301242) or a combustible gas detector. Any other product or solutions are unacceptable.
7. Only use tools that are in good working order with proper calibration.
8. Wear appropriate attire and PPE while servicing or maintaining any CNG system.
Due to the presence of high-pressure and flammable fuel, CNG fuels systems are a form of hazardous energy
storage.
CNG systems must be maintained and inspected exclusively by trained personnel with qualifications in accordance
with the applicable codes.
