SAFETY PRECAUTIONS WHILE WORKING IN WELDING SHOP-1

Gas welding

• One should never use a leaking gas cylinder.
• One should never handle oxygen cylinders, valves, regulators, hoses or fittings with oily hands.
• Welder must not mix the gases in one cylinder.
• One should never transfer the gas from one cylinder to another.
• One should clearly mention the type of gas on the cylinder (i.e. oxygen, acetylene, etc.).
• One should use nose masks where the local exhaust ventilation is not practicable. Insist the safety officer to provide proper ventilation system.
• Always avoid skin contact with fluxes, which contain fluorides. If they will penetrate the skin, they produce severe irritation.
• One should never weld the parts, which are coated with toxic material such as lead, cadmium, zinc, mercury, or paint containing toxic. Any such coatings must be removed prior to welding.
• Acetylene gas should not be brought in direct contact with the unalloyed copper (except in torch) as it may result in a violent explosion.
