What is the minimum distance required between a direct fire vaporizer and an above ground LP container?

The minimum distance required between a direct fire vaporizer and an above ground LP container is established for safety reasons. A direct fire vaporizer utilizes heat to convert liquid LP gas into a vapor for use, and this process involves high temperatures that could potentially pose a risk to nearby containers.

Having a minimum distance of 10 feet creates a buffer zone that helps to mitigate the risk of heat exposure to the LP container, which could result in dangerous situations, including the risk of a fire or explosion. Compliance with this distance requirement is crucial for ensuring the safety of personnel and nearby structures, as well as minimizing the likelihood of accidents during operations involving LP gas.

The other options—5 feet, 15 feet, and 20 feet—do not align with the standard regulation, reflecting either too short a distance that may not adequately protect against thermal hazards, or excessive distances that are not necessary for safety protocols. Hence, 10 feet strikes an appropriate balance between safety and practicality.
