How should gas be vented from pressure relief devices on portable storage containers?

Venting gas from pressure relief devices on portable storage containers is essential for ensuring safety and preventing the buildup of pressure that could lead to hazardous situations. The appropriate method for venting gas is upward and unobstructed. This approach allows any released gas to disperse safely into the atmosphere, minimizing the risk of accumulation at ground level, where flammable vapor could pose a threat.

Upward venting prevents the possibility of the gas accumulating in low areas, where it could potentially ignite or create an explosive environment. Furthermore, keeping the vent unobstructed ensures that gas can flow freely without obstruction or restriction, which is critical for the device to function properly during overpressure scenarios. Overall, this practice adheres to industry safety standards and helps promote a safe working environment.
