Up to 25 percent of fatalities in shipyards result from fires and explosions caused by hot work.

Bureau of Labor Statistics (BLS)

Hot work includes welding, cutting, burning, abrasive blasting, and other heat-producing operations. Hot work presents an increased risk of fire and explosion hazards because it is most often performed in confined and enclosed spaces. [29 CFR 1915.51, 29 CFR 1915.53, 29 CFR 1915.54, 29 CFR 1915.55, 29 CFR 1915.56, and 29 CFR 1915 Subpart P]
