Which statement is true regarding the use of safety relief valves on LP gas containers?

Safety relief valves on LP gas containers are designed to prevent excessive pressure buildup, which can occur due to temperature increases or vaporization of the liquid gas within the container. One important safety feature is that these valves should discharge vertically upward. This orientation ensures that any gas released is directed safely away from the container and any potential sources of ignition, as well as from personnel in the vicinity.

Discharging vertically minimizes the hazards associated with potential gas accumulation around the container and aligns with best practices for venting gas safely into the atmosphere. This approach also helps to prevent gas from entering spaces where it could pose a risk.

While there are various installation and safety guidelines for LP gas systems, the necessity for a vertical discharge is critical for maintaining safety standards and ensuring that the release of gas doesn’t create unsafe conditions.
