Applies to the prevention of electric shock to welders. Sets out the requirements for safety of circuit wiring on power sources for welding and allied processes and the precautions to be taken when operating such power sources. Includes plasma arc power sources and reference to particular hazards due to their high open-circuit voltages. The appendices illustrate and describe the correct method of connection between adjacent power sources to minimize the likelihood of electric shock across adjacent power source leads. Examples of recorded fatal accidents are included and procedures for rescue and resuscitation in the case of electric shock are described and illustrated.
