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.

inspected. Place an inspection label stating the
inspection date and inspecting agency identification
on each container.
