Inspecting the CNG Fuel Cylinder

Have a qualified inspector inspect compressed natural gas (CNG) fuel cylinders for damage or deterioration. Note cuts, cracks, gouges, abrasions, discoloration, broken fibers, loose brackets, damaged gaskets or isolators, heat damage, or other problems.

Refer to the Compressed Gas Association's (CGA) pamphlet C-6.4, Methods for External Visual Inspection of Natural Gas Fuel Containers and Their Installations, for inspection requirements and inspector qualifications.

After inspection, an accurate and reliable written report should be provided for each container inspected. Place an inspection label stating the inspection date and inspecting agency identification on each container.
