Inspection of 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 Compressed Gas Assocation (CGA) pamphlet C-6.4, Methods for External Visual Inspection of Natural Gas Fuel Containers and Their Installations, for inspection requirements and inspector qualifications.
