What should be confirmed about an empty cylinder before it is returned to a supplier?

• A. It is labeled full.
• B. It is properly labeled empty, secured, and transported by approved methods.
• C. It is transported in any vehicle.
• D. It is not required to be secured.

Answer: (B)

The safety and proper handling concept here is that an empty cylinder must be clearly identified and moved in a controlled way to prevent confusion or hazards during return. The best practice is to ensure the cylinder is properly labeled as empty, with the valve closed and the cylinder secured and transported by approved methods. Labeling as empty communicates that there is little to no pressure left and reduces the chance of someone attempting to refill or mishandling it. Securing the cylinder and using approved transport methods prevents it from rolling, being damaged, or venting while in transit, which protects people and property and complies with regulations.

Labeling it as full would mislead handlers and is unsafe. Transporting in any vehicle without securing it creates a risk of movement or tipping. And saying it does not need to be secured ignores the fundamental safety practice of keeping cylinders upright and restrained during transport.
