Many industries have converted their fleet vehicles to run on safe, cleaner-burning natural gas. Fleets of trucks, buses and cars owned & operated by cities, governments, school districts, refuse collection companies and a host of other private operations are now running on Compressed Natural Gas (CNG).

CNG cylinders and fuel systems powering natural gas vehicles must be visually inspected for external damage and deterioration at least every 36 months or 36,000 miles, after a motor vehicle accident, or at the time of reinstallation. CSA Group's CNG Fuel System Inspector Certification was developed to meet the needs of the natural gas vehicle market.


CSA Group's CNG Fuel System Inspector Certification program covers the inspection of containers, valves, pressure relief devices (PRDs) including vent system and other fuel system components of CNG-fueled vehicles. Certified personnel will have demonstrated proficiency in inspecting CNG vehicle cylinders and fuel systems, identifying and documenting defects, and the safe handling of cylinders and fuel system components. This will help enable them to perform assigned tasks safely.

This certification complies with the International Organization for Standardization (ISO) 17024 standard for personnel certification programs.
