In an industrial setting A Hot Work is any work or task that requires or involves open flames or any other sources of heat that could ignite flammable or combustible materials in the work area. The USA standards applicable to this type of job are regulated by OSHA. They are: • Part Number: 1910 Part Title: Occupational Safety and Health Standards Subpart: H Subpart Title: Hazardous Materials Standard Number: 1910.110 Title: Storage and handling of liquefied petroleum gases.
• Part Number: 1915 Part Title: Occupational Safety and Health Standards for Shipyard Employment Subpart: B Subpart Title: Confined and Enclosed Spaces and Other Dangerous Atmospheres in Shipyard Employment Standard Number: 1915.14 Title: Hot Work.
• Part Number: 1917 Part Title: Marine Terminals Subpart: G Subpart Title: Related Terminal Operations and Equipment Standard Number: 1917.152 Title: Welding, cutting and heating (hot work) (See also § 1917.2, definition of Hazardous cargo, materials, substance or atmosphere).
