How must a DOT cylinder be installed?

A Department of Transportation (DOT) cylinder must be installed on a stable, non-combustible surface for safety reasons. Using concrete, masonry, or metal provides a safe and secure installation that is resistant to fire hazards. These materials help to ensure that the cylinder is protected from environmental factors that could lead to corrosion or structural instability, thereby maximizing the safe storage and use of liquefied petroleum gases.

In addition to providing a stable base, installing a DOT cylinder on concrete, masonry, or metal surfaces minimizes the risk of damage or accidents that could occur with less durable materials. It also ensures that the cylinder remains upright and secure, which is critical for preventing leaks or other hazardous situations that can arise if the cylinder falls or is compromised in any way. Therefore, the practice as outlined in NFPA 58 adheres to the principles of safety and compliance necessary for handling liquefied petroleum gas.
