Arc rays: harmful to people’s eyes and skin. Arc rays from the welding process produce intense visible and
invisible ultraviolet and infrared rays that can burn eyes and skin.
• Always wear a welding helmet with correct shade of filter lens and suitable protective clothing including welding gloves
whilst the welding operation is performed.
• Measures should be taken to protect people in or near the surrounding working area. Use protective screens or barriers to
protect others from flash, glare and sparks; warn others not to watch the arc.
Fire hazard. Welding on closed containers, such as tanks, drums, or pipes, can cause them to explode. Flying sparks
from the welding arc, hot work piece, and hot equipment can cause fires and burns. Accidental contact of
electrode to metal objects can cause sparks, explosion,
overheating, or fire. Check and be sure the area is safe before doing any welding.
• The welding sparks may cause fire, therefore remove any flammable materials away from the working area, at least
39.37ft from the welding arc. Cover flammable materials and containers with approved covers if unable to be moved
from the welding area.
• Do not weld on closed containers such as tanks, drums, or pipes, unless they are properly prepared according to the
required Safety Standards to ensure that flammable or toxic vapors and substances are totally removed, these can cause
an explosion even though the vessel has been “cleaned”.
Vent hollow castings or containers before heating, cutting or welding. They may explode.
• Do not weld where the atmosphere may contain flammable dust, gas, or liquid vapors (such as petrol)
• Have a fire extinguisher nearby and know how to use it. Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas. Be aware that welding on a ceiling, floor, bulkhead, or
partition can cause fire on the hidden side.
Gas Cylinders. Shielding gas cylinders contain gas under high pressure. If damaged, a cylinder can explode.
Because gas cylinders are normally part of the welding process, be sure to
treat them carefully. CYLINDERS can explode if damaged.
• Protect gas cylinders from excessive heat, mechanical shocks, physical damage, slag, open flames, sparks, and arcs.
• Insure cylinders are held secure and upright to prevent tipping or falling over.
• Never allow the welding electrode or earth clamp to touch the gas cylinder, do not drape welding cables over the
cylinder.
• Never weld on a pressurized gas cylinder, it will explode and kill you.
• Open the cylinder valve slowly and turn your face away from the cylinder outlet valve and gas regulator.
Gas build up. The buildup of gas can cause a toxic environment, deplete the oxygen content in the air
resulting in death or injury. Many gases used in welding are invisible and odorless.
• Shut off shielding gas supply when not in use.
• Always ventilate confined spaces or use approved air-supplied respirator.
