WELDING PRECAUTIONS
In common with other operations involved in the workshop, Welding creates hazards which if not identified, constitutes a threat to safety of both the welder and other workers in the vicinity. Some precautions observed during welding include:
(i) Correct protective clothing must be worn (Apron, Hand Gloves etc).
(ii) Safety boots with hard sole should be worn to avoid being hurt when a hot metal is marched mistakenly.
(iii) Ensure adequate ventilation.
ARC WELDING
(iv) Welding mask should be worn to avoid arc - eye.
(v) Correct nose mask/respirator must be worn so that you don't inhale poisonous gases or fumes.
(vi) Ensure that the isolating switches are to hand so that the main supply can be disconnected as quick as possible.
(vii) Ensure that the equipment earth lead is securely fastened to a satisfactory earth point.
(viii) Ensure that the welding lead, Welding return and earth lead are of adequate size for the current being used.
(ix) Effort should be made to avoid welding in damp or wet conditions, Since the danger from electric shock is much increased etc.
GAS WELDING
(x) Never use a naked flame to find a suspected leak, Use a brush to apply a soapy water to any joint suspected of leaking. Bubbles will appear if there is a leak.
(xi) Check regulators, hoses and blowpipes at frequent intervals, discard any damaged equipment.
(xii) Do not allow oil or grease to get on cylinder. Oxygen reacts violently with oil and grease and may explode.
(xiii) When the equipment is not in use, or when the cylinder is empty, close the cylinder valves.
(xiv) Always open the cylinder valves slowly.
(xv) Do not leave the blowpipe near hot metal or any escaping acetylene gas may be ignited etc.
(i) Correct protective clothing must be worn (Apron, Hand Gloves etc).
