What is the recommended orientation for storing gas cylinders to enhance safety?

• A. Horizontal on its side
• B. Vertical and chained
• C. Upside down
• D. At an angle

Answer: (B)

Storing gas cylinders upright is essential because the valve sits at the top, and keeping the cylinder vertical protects that valve and ensures it functions properly. When cylinders are vertical, the load stays on the main body rather than on the valve stem, reducing the risk of valve damage or leaks. For liquefied gases, keeping the cylinder upright helps prevent liquid from being drawn into the valve, which can cause dangerous releases. Securing the upright cylinder with a chain or strap to a wall, rack, or fixed support prevents tipping or rolling if someone bumps the area, a common accident that can turn a safe cylinder into a hazard.

Storing on its side, upside down, or at an angle increases the chance of valve damage, rollaway movement, and accidental releases, so those orientations are avoided in favor of vertical and properly restrained storage.
