Touching 'live' electrical components, including the electrode and the workpiece, can result in a burn injury or, more seriously, electric shock.
Electric shock
Electric shock can kill, either by direct action on the body or by a resultant fall if working at height.
Most electrical accidents are avoidable and only occur as a result of carelessness, lack of training, poor workmanship or faulty equipment.
Welders must never become complacent about the hazards associated with electric arc welding.
Safe working practices should be followed at ALL times.
