• A. True
• B. False
• C. Only If Chained
• D. Only If Labeled

Answer: (B)

Gas cylinders are high‑pressure containers that must be protected from tipping, damage, and leaks. When you leave a job site, you should not leave cylinders unsecured or with the valve left open. If a cylinder is knocked over or a valve leaks, it can release gas rapidly, create a fire or explosion hazard, or displace breathable air in the area. Chaining or labeling a cylinder does not eliminate these risks by itself; the valve must be closed and the cylinder secured in an upright position in a designated storage area or rack, with a protective cap in place when not in use. So, it’s not generally okay to leave cylinders on site during breaks or after work. Close the valve, cap the valve if possible, and secure the cylinder in a safe location.
