If a cylinder valve is hard to open, which action is recommended?

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

Answer: (D)

When a cylinder valve is hard to turn, treat it as a potential safety hazard and act to prevent a gas release. Forcing or heating a stuck valve can damage the valve, fittings, or cylinder and may cause a sudden, uncontrolled release of propane, which is dangerous and can lead to fire or explosion. The correct response is to remove the cylinder from service and notify a supervisor or the supplier so trained personnel can inspect and evaluate the valve and cylinder for defects, contamination, frost, or other issues. In the meantime, keep the cylinder upright and away from ignition sources and follow your site's safety procedures for securing and reporting hazardous equipment.
