#ToolboxTuesday - Compress Gas Cylinder Safety

When handled or stored incorrectly, a cylinder can go up like a rocket. As we’ve seen, this can not only cause property damage but can be fatal as well. Watch the video below to see how MythBusters created a cylinder rocket by shearing the valve off a compressed air cylinder. The cylinder travelled 63 km per hour, breaking clean through a cinder block wall!

General Precautions

To move cylinders, securely fasten them to a suitable cylinder transporting device. At the site, chain or otherwise secure the cylinder in place. Remove the valve cap only after the cylinder has been safely installed, then check the cylinder valve and fixture. Remove any dirt or rust. Grit, dirt, oil or dirty water can cause gas leaks if they get into the cylinder valve or gas connection.

Never open a damaged valve. Contact your gas supplier for advice. Maintain all cylinders regularly and check for leaks each time a cylinder is used.

Check for leaks at cylinder valves, regulators, and connections. When testing for leaks use soapy water, approved test leak solution, or gas detection equipment. Never use a flame. If an uncontrolled leak occurs, shut off the electrical power and call the fire department. Remove other ignition sources and leave the area.

Use only the proper equipment for discharging a particular gas from its cylinder. Never use homemade adaptors or force connections between the cylinder valve outlet and gas handling equipment.

Storage 

Use a proper storage site; regulations and procedures must be followed.

  •  Secure all the cylinders upright in a well-ventilated area

  • Keep full and empty containers separate

  • Keep cylinders away from open flames, electric arcs, molten slag, sparks, and radiators

  • Do not store in temperatures above 54 degrees Celsius

  • Oxygen and fuel gas cylinders must be at least 6 metres (20 feet) apart

  • Do not smoke near cylinders
