What is the minimum distance required between the relief valve on an ASME container of 125 water gallons capacity and a building opening below the discharge level?

The minimum distance required between the relief valve on an ASME container of 125 water gallons capacity and a building opening below the discharge level is 5 feet. This requirement is designed to ensure safety by preventing the discharge of gas or vapor from the relief valve from entering the building.

Relief valves are critical components that release pressure to prevent container failure during over-pressurization. If gas were to discharge too close to an opening, there could be a risk of gas accumulation within the building, which could lead to hazardous situations, such as fires or explosions.

Regulations typically dictate these distances to protect both personnel and property from potential hazards associated with gas storage and handling. The specified distance of 5 feet strikes a balance between safety and practicality in residential or commercial settings. Following this guideline helps maintain a safe environment around LP gas containers.
