Committee Scope: This Committee shall have primary responsibility for
documents on fire and explosion hazards associated with compressed natural
gas (CNG) and liquefied natural gas (LNG) engine fuel systems on vehicles of
all types and for refueling stations and associtated storage.

The Committee shall coordinate its documents with the Committee on the
National Fuel Gas Code with respect to natural gas piping within the scope
of that Committee, with the Committees on Industrial Trucks, Fire Safety for
Recreational Vehicles, and Marine Fire Protection with respect to engine fuel
