Hot work operations include job set-up and placement, inspection and testing of equipment, as well as actual performance of the hot work.

During hot work operations, conditions can change. Piping may leak into the space, the vessel may move, or different types of work (painting or cleaning) may be conducted in adjacent spaces. Therefore, maintaining safe conditions requires constant precautions, including frequent inspection and tests performed by the Shipyard Competent Person (SCP).


The Confined or Enclosed Spaces and Other Dangerous Atmospheres module should be reviewed before proceeding with this section. Also review the hot work requirements found in 29 CFR 1915.51, 29 CFR 1915.55, 29 CFR 1915.56, and 29 CFR 1915 Subpart P.

Specific work practices are required for hot work. The majority of the requirements for hot work are discussed in the enclosed space section. Additional requirements for hot work in confined spaces and in other locations are listed in those sections.
