    Abstract - (Show below) - (Hide below)

    Specifies safety requirements for arc welding and allied processes, to prevent electric shock and minimize associated hazards, describes practices and safeguards that should be adopted by welders (including requirements for cable connections for alternating and direct current power sources, and requirements for any ancillary equipment) and gives examples of ways that shocks have been received and actions that may be taken in the event of a welder receiving an electric shock.

    Scope - (Show below) - (Hide below)

    This Standard sets out safety requirements for arc welding and allied processes, to reduce the possibility of electric shock and minimize associated hazards. It includes requirements for cable connections for alternating and direct current power sources, as well as requirements for hazard-reducing devices and other ancillary equipment. It also describes practices and safeguards that should be adopted by welders and provides examples of situations that present an increased risk of electric shock. NOTES: 1 Other aspects of welding safety are covered in other Standards. 2 Typical electrical hazards are described in Appendix A. 3 Some fatal electrical accidents are reported in Appendix B. 4 Information on health aspects of electric fields, magnetic fields and pacemakers is given in Appendix C.
