In what position must welding cylinders be stored and used?

Welding cylinders must be stored and used in an upright position to ensure safety and prevent potential hazards. When cylinders are upright, the pressure relief device is located at the top, which allows for the safe escape of gas if needed. Additionally, maintaining the cylinders upright prevents risks associated with tipping and falling, which could lead to leaks or damage to the regulator and valve.

Storing in this position also helps maintain stability and makes it easier to manage gas flow and connectivity during welding operations. Using cylinders in an upright position is a standard safety practice in welding and cutting operations, which is crucial for worker safety and the integrity of the equipment.
