Where should propane containers not be mounted on a vehicle?

Propane containers should not be mounted on the exterior of the rear wall or bumper due to safety concerns. This location poses a significant risk because it is exposed to potential impacts and hazards from other vehicles, debris, or obstacles on the road. In the event of an accident or collision, there is a higher likelihood of damage to the propane container, which could lead to leaks or even explosions.

In contrast, vapor-resistant compartments, the chassis of the vehicle, and the tongue of a trailer are generally safer options for mounting propane containers. These locations provide protection from external elements and impacts, thereby mitigating the risks associated with transporting propane. Such placements are also likely to meet regulatory requirements for safe propane storage and transportation on vehicles.
