What is the primary requirement for the installation of propane containers in vehicles?

The primary requirement for the installation of propane containers in vehicles focuses on safety and containment. Installing them in a vapor-resistant compartment ensures that any potential leaks are contained, preventing hazardous gas from escaping into the passenger area or creating a risk of fire or explosion. This type of compartment is designed to safely handle the gas and prevent it from coming into contact with the vehicle's interior, where it could pose a serious safety issue.

While there are alternative methods of storing propane and considerations for placement, only the proper installation in a vapor-resistant compartment provides the necessary safety measures to mitigate risks associated with propane use in vehicles. Safety codes and regulations emphasize this requirement to protect both the passengers and the integrity of the vehicle.
