What should be done if there is a leak around the valve stem of a fuel gas cylinder is detected?

• A. Keep cylinder wet with a heavy water stream
• B. Tighten the packing nuts or close the cylinder valve
• C. Seal the leak with heavy duty tape or industrial adhesive
• D. Immediately evacuate the area

Answer: (B)

Leaking around the valve stem means the packing that seals the stem isn’t providing a tight seal. The first thing to do is tighten the packing nut to compress the packing material and reduce or stop the leak. If tightening doesn’t stop the leak, close the cylinder valve to shut off the gas supply completely. This prevents further release while you secure the situation or arrange for repair. Do not try to seal a gas leak with tape or adhesives, and avoid using water streams as a fix. If the leak cannot be controlled quickly or if there’s a strong gas odor, evacuate the area and follow your site’s emergency procedures.
