Which statement describes proper cylinder storage?

• A. Cylinders should be stored upright and secured to prevent tipping.
• B. Cylinders can be stored with full and empty together.
• C. Empty cylinders can be left on site indefinitely.
• D. Cylinders should be stored in a way that allows them to be knocked over for easy access.

Answer: (A)

Safe cylinder storage means keeping cylinders upright and secured so they can’t tip or roll. When a cylinder tips, the valve can be damaged, leaks can occur, or the cylinder could become a dangerous projectile. Securing cylinders to a rigid support or wall with a strap or chain prevents movement and protects the valve. In addition, keep the protective cap on when not in use and store cylinders in a well-ventilated area away from heat, sparks, or flames. Storing full and empty together can cause confusion and improper handling, empty cylinders left on site indefinitely can still present hazards, and a setup that allows cylinders to be knocked over is dangerous because it risks valve damage and leakage.
