The first consideration for safety in welding is the location and peculiarities of the space in which the welding operation is to be performed.
Weld or cut only in locations specifically designated for this purpose unless you have obtained approval of the job and have taken the necessary precautions to eliminate fire and explosion hazards.
Do not weld in any location outside the shop unless you take the necessary precautions and get authorization. Before you weld in any compartment, room, tank, or adjacent space which contains or which has contained flammable or explosive materials, liquids, or vapors, make sure they are:
- made safe,
- tested, and
- proclaimed safe.
These restrictions also apply to closed drums, tanks, and similar containers.
Do not permit welding or cutting in the following situations:
- in areas not authorized by management
- in sprinklered buildings while such protection is impaired
- in the presence of explosive atmospheres (mixtures of flammable gases, vapors, liquids, or dust with air)
- inside uncleaned or improperly prepared tanks or equipment which have previously contained such explosive atmospheres or have the potential for explosive atmospheres
- in areas with an accumulation of combustible dust
- in areas near the storage of large quantities of exposed, readily ignitable materials such as bulk sulfur, baled paper, or cotton.
