What is the maximum aggregate water capacity for LP-gas fuel containers installed on passenger-carrying vehicles?

The maximum aggregate water capacity for LP-gas fuel containers installed on passenger-carrying vehicles as specified by NFPA 58 is indeed 200 gallons. This limit is established to ensure safety and manage the risks associated with LP-gas usage in vehicles that carry passengers.

The rationale behind this maximum capacity is related to the inherent hazards of LP-gas. LP-gas is flammable and poses a risk of explosion; therefore, regulations impose limits on the amount that can be stored on vehicles occupied by passengers. By capping the water capacity at 200 gallons, it helps reduce the potential severity of incidents in the event of a leak or an accident, thereby enhancing overall safety for passengers and the vehicle driver.

Furthermore, these regulations reflect careful consideration of factors such as the vehicle's design, the safe operation of gas containers, and specific installation requirements. Understanding this threshold is crucial for compliance with safety standards and for the effective management of LP-gas systems in passenger vehicles.
