I am wondering about the applicability of NFPA 30A. Is the standard intended to apply only to automotive repair facilities (e.g., dealerships, lube shop/Firestone, etc.) or does it include heavy machinery (e.g., construction equipment, bull dozers, back hoes, tracked vehicles) repair facilities? There is no clear definition of what is meant by "motor vehicle" (definitions 22.214.171.124) or "automotive".
The Purpose (Paragraph 1.2) indicates "The purpose of this document shall be to provide reasonable safeguards for dispensing liquid and gaseous motor fuels into the fuel tanks of automotive vehicles and marine craft." The definitions discuss work such as engine overhauls, painting, body and fender work, and repairs that require draining of the motor vehicle fuel tank are performed on motor vehicles, showrooms, lubrication, inspection, tune-ups, oil, antifreeze, transmission fluid, brake fluid, air conditioning refrigerants, etc.), brake system repairs, and tire rotations - terms commonly used for automotive repairs and not necessarily heavy equipment maintenance.
