Always Ensure to Follow Standards bellow:
CSA Standard W117.2-94, Safety in Welding, Cutting, and Allied Processes.
All equipment must be CSA Standards C22.2 No.60 or be acceptable to the regulatory authority.
All welding operations present common hazards. These include the dangers of burns from hot metal, burns to the eyes or skin from ultraviolet radiation, danger from sparks or slag, welding fumes and risk of fire. During air arcing, noise is also a hazard that must be controlled. If the welder uses one of the many electrical processes involved in welding, another hazard is introduced. This is the possibility of electric shock.
If you feel that because relatively low voltages are used, there’s not much danger of electric shock. You’d be wrong.
When currents are high as they are during welding, and/or skin resistance is low, an electrical shock can occur. To
minimize the shock hazard, follow these rules:
1. Cover or arrange welding leads to prevent contact with falling sparks, slag or hot surfaces.
2. Never change electrodes with bare hands, wet gloves, or when standing on wet floors or grounded surfaces.
3. Make certain the welding machine is properly grounded.
4. Never disconnect the welding leads while the machine is on.
5. Do not use a work lead if there is any damage to the insulation within 10 feet of the stinger. Damage to the insulation beyond this point can be repaired if the repaired insulation provides as much protection as did the original covering.
6. Keep welding leads dry and free of grease or oil—which can cause premature breakdown of the insulation.
7. Suspend leads from overhead supports when possible. This helps control the trip hazards they may create and
also lessens the likelihood that the lead will be damaged by being walked on or driven over.
8. Take special care to keep leads away from power supply cables and high tension lines.
Remember, even minor shocks can be dangerous. They may not be enough to cause a painful burn, unconsciousness or
death, but just being startled or an involuntary muscle contraction can cause you to be injured from a fall, accidental contact with a machine, or a similar unexpected mishap.
Don’t Take Chances – Weld safely!
