What should you do if a cylinder valve is hard to open?

• A. Remove from service and notify supervisor or supplier for evaluation.
• B. Ignore it and try again later.
• C. Lubricate the valve with oil.
• D. Force it open with a wrench.

Answer: (A)

A valve that’s hard to open on a cylinder signals a potential fault that could lead to a dangerous release if forced. The safest action is to remove the cylinder from service and notify a supervisor or supplier so qualified personnel can inspect and determine whether the valve needs repair or replacement. Do not try to lubricate the valve, do not force it with tools, and do not ignore the issue. In the meantime, secure the cylinder upright and tag it as out of service to prevent accidental use.
