If a cylinder has leaking fittings or valves, what action should be taken?

• A. Open
• B. Close
• C. Vent and tag
• D. Move to service area

Answer: (A)

When a cylinder has leaking fittings or valves, the first step is to stop the flow by closing the valve. This isolates the cylinder and prevents more gas from escaping, reducing the immediate hazard and giving you control to assess and handle the situation safely. After the valve is closed, tag the cylinder to indicate it is defective and should not be used, then move it to the designated service area for inspection or repair. Opening the valve would only increase the leak and raise the risk, so it’s not the correct action. Merely moving the cylinder or venting without securing the leak doesn’t address the immediate danger and can lead to further hazards.
