XXXXXXX Pty Ltd | Safe Work Procedure – Electric Welding | Revision: XX | DD/MM/YYYY

PERSONAL PROTECTIVE EQUIPMENT TO BE UTILISED Safety eyewear & a welding helmet or hand shield with filter plate and cover plate is

mandatory. Hearing Protection. Fire retardant long sleeve coveralls and without cuffs, tears, rips, fraying or wear. Flameproof skullcap. Safety Boots. Specialty respirators for cutting hazardous materials. Flame proof gloves. Rubber gloves.

LICENSE / PERMIT / TRAINING REQUIRED Operators must have completed a training program recognised by XXXXXXXXX and be

authorised to perform this procedure.

START UP PROCEDUREBefore starting check that:

The work area is clear. Remove any trip hazards. There is adequate ventilation. You have easy access to a fire blanket and first aid kit.

DO NOT OPERATE UNSAFE MACHINERY. If the Welder is not in a safe operational condition, advise your supervisor or maintenance staff immediately.

OPERATIONAL PROCEDURE Because of their potentially explosive nature, do not attempt welding/cutting or hot work

to drums, barrels, tanks or other containers under any circumstances. Do not weld directly on a concrete floor. Heat from the arc can cause steam to build up

in the floor, which could cause an explosion.

XXXXXXX Pty Ltd | Safe Work Procedure – Electric Welding | Revision: XX | DD/MM/YYYY

Position the welding cables to avoid sparks and molten metal coming into contact with them.

Keep cables free from grease and oil. Position the cables so they will not be driven or walked over. If the welding operation must be done on steel or other conductive material, an

insulating mat must be used under the operator. Electric welders can kill by electric shock.

If the welding area is wet or damp or the operator is actively perspiring then he/she should wear rubber gloves under the welding gloves.

Clean all metal to be welded by wire brushing or other methods. Protect your eyes and body from flying slag or chip when wire brushing the finished

bead or chipping slag. Do not leave unused electrodes or electrode stubs on the floor whereby they create a

slipping hazard. Hot metal should be handled with metal tongs or pliers. When quenching hot metal in water it should be done very carefully to avoid steam

burns. Any metal left to cool should be marked “HOT” with soapstone. The emergency switch should be located close to the operator. Welding should not be performed from ladders. “Welding in Progress” signs should be displayed in the area where welding is being

carried out.

CLOSEDOWN PROCEDURE Remove electrodes from the holders. Store holders away from accidental contact. Disconnect the welder from the power source. Clean the work area, remove all waste and secure any tools.

EMERGENCY PROCEDURE Hit the emergency stop button. Lock out the welder with a safety tag. Contact your supervisor immediately.

ADVISORY NOTESFire Prevention:The electric welder is capable of producing temperatures in excess of 3,000°Celcius. A safe workplace can be achieved by using metal or fire-resistant curtains as fire barriers. The floor should be concrete or another fire-resistant material. Cracks in the floor should be filled to prevent sparks and hot metal from entering.

When work cannot be moved to a fire-safe area then the area should be made safe by removing or protecting combustibles from the ignition source. In certain welding situations it may be necessary to ask someone to watch for fires that could go undetected until the welder has finished the job. Suitable fire extinguishing equipment such as buckets of sand or a dry chemical extinguisher, large enough for the situation, should be readily available.

Ventilation:

XXXXXXX Pty Ltd | Safe Work Procedure – Electric Welding | Revision: XX | DD/MM/YYYY

The welder should be located in an area with adequate ventilation. In general, when welding is being done on metal not considered hazardous, a ventilation system that will move a minimum of 2000 cubic feet (200 cubic metres approx) per minute of air per welder is satisfactory. However many materials are considered very hazardous and should be welded only in adequately ventilated areas to prevent the accumulation of toxic materials or to eliminate possible oxygen deficiency not only to the operator, but to others in the immediate vicinity. Such ventilation should be provided by an exhaust system located as close to the work as possible.

When welding or cutting metal with hazardous coatings such as galvanised metal, the operator should use a supplied air type respirator or a respirator specially designed to filter the specific metal fume. Materials included in the very hazardous category are welding rod fluxes, coverings or other materials containing fluorine compounds, Zinc, Lead, Beryllium Cadmium and Mercury. Some cleaning and degreasing compounds combined with the metals they were cleaned with are also hazardous. Always follow the manufacturer’s precautions before welding or cutting in the presence of these materials.

IF YOU HAVE NOT BEEN TRAINED IN THE TASK OR YOU ARE NOT SURE HOW TO PERFORM THE TASK OR OPERATE THE MACHINERY, DO NOT OPERATE THE

MACHINERY AND ADVISE YOUR SUPERVISOR IMMEDIATELY.

OPERATOR’S STATEMENTI have been trained in and I understand this procedure.

I will perform my tasks to the best of my ability and in accordance with this safe working procedure.
