GAS Cylinders

SAFETY PRECAUTIONS

Cylinders of protective welding gas contain gas under pressure. If a cylinder is damaged, it can explode. As cylinders of gas are part of the welding environment, they should be handled with caution.

•Protect gas cylinders from excessive heat, shock, slag, exposed flames, sparks from the welding arc.

•Store cylinders upright in a stationary rack or cylinder holder so that they cannot fall over.

•Keep cylinders away from welding circuits or any other electrical circuit.

•Never place a welding torch on a gas cylinder.

•A welding electrode should never make contact with a gas cylinder.

•Never weld a pressurised cylinder, there is a risk of explosion.

•Only use protective welding gas cylinders, regulators, hoses and fittings designed for this specific purpose, make sure they and associated items are in good condition.

•Do not stand in front of the gas outlet when opening the gas valve on a cylinder.

•Keep the valve protection cap in place except when using or connecting the cylinder.

•Read and follow the instructions concerning the use of cylinders of compressed gas and associated equipment and the other publications listed in the safety standards.

WELDING CAN CAUSE FIRE OR EXPLOSIONS

Welding container-like objects such as tanks, drums or pipelines can cause such objects to burst.

Sparks are projected from the welding arc. The projection of sparks, hot items and hot equipment can cause fire and burns.

Accidental contact of the electrode with metal objects can cause sparks, explosions, overheating or fire. Before welding in such cases, check that there is no danger.

•Protect yourself and others from the projection of sparks and hot metal.

•Do not weld in places where sparks can fall on flammable substances.

•Move flammable substances at least 10.7 metres/35 feet from the welding arc. If this is not possible, cover them carefully with approved protective covering.

•Sparks and other hot welding matter can propagate from one area to another through small cracks and openings.

•Check for any fire that may start and have a fire extinguisher to hand.

•Do not weld container-like objects such as tanks, drums or pipelines unless they have been properly prepared.

•Connect the cable to the work piece as near as possible to the welding area to avoid having to feed the current over long hazardous distances which could cause electrocution or fire.

•Do not use welding equipment to defrost frozen pipes.
