Abstract

Specifies precautions to be taken prior to and during hot work (including welding and allied processes), to prevent the possibility of fire or explosion, which may result in harm to persons or property. In particular, such precautions apply to hot work during manufacturing, construction, maintenance, repairs, demolition and where plant or equipment has contained flammable, combustible or explosive material. Measures for the protection of operators against electric shock, asphyxiation, poisoning and other hazards are not covered by this Standard, which also does not deal with protective clothing. Although primarily oriented to hot work that is related to welding and allied processes, this Standard can generally be applied to other forms of ignition sources in hazardous areas.
