Cylinders awaiting resale must be stored in which positions?

• A. Horizontal and Resting
• B. On Their Side with Relief Valve Up
• C. Diagonally
• D. Vertical and Upright

Answer: (C)

Storing cylinders that are waiting to be resold is about preventing movement and protecting the valve area. Placing them diagonally gives a resting angle that makes it harder for the cylinder to roll or tip and helps keep the valve end from bearing weight or being struck directly. This orientation reduces the chance of accidental damage or leaks while the cylinders are out of service.

Other common positions carry higher risks in this context: lying on the side or having the relief valve up on a side orientation can expose the valve to damage or allow movement that could lead to leaks, and a fully upright position is typically safe for active use but isn’t the chosen setup in this scenario.
