NFPA 51B-2019 Standard for Fire Prevention During Welding, Cutting, and Other Hot Work

NFPA 51B-2019 Standard for Fire Prevention During Welding, Cutting, and Other Hot Work. 3.39’ Welding and Allied Processes. Processes such as arc welding, oxy—fuel gas welding, open-flame soldering, brazing, thermal spraying, oxygen cutting, and arc cutting. 3.3.10’ Welding Blanket. A heat-resistant fabric listed, approved, and designed to be placed in the vicinity of a hot work operation: intended for use in horizontal applications with light to moderate exposures such as that resulting from chipping, grinding, heat treating, sand blasting, and light horizontal welding; designed to protect machinery and prevent ignition of combustibles such as wood that are located adjacent to the underside of the blanket. 3.3.11’ Welding Curtain. A heat-resistant fabric listed, approved, and designed to be placed in the vicinity of a hot work operation, Intended for use in vertical applications with light to moderate exposures such as that resulting from chipping, grinding, heat treating, sand blasting, and light horizontal welding; designed to prevent sparks from escaping an area. 3.3.12’ Welding Pads. A heat-resistant fabric listed, approved, and designed to be placed directly under a hot work operation such as welding or cutting, intended for use in horizontal applications with severe exposures such as that resulting from molten substances or heavy horizontal welding: designed to prevent the ignition of combustibles that are located adjacent to the underside of the pad. Chapter 4 Responsibility for Hot Work 4.1’ Management. Management shall be responsible for the safe operations of hot work activity. 4,1.1 Management shall establish permissible areas for hot work. 4.1.2 Management shall designate a permit authorizing individual (PAl). 4.1.3 All equipment shall be examined to ensure it is in a safe operating condition. 4.1.4 When found to be incapable of reliable safe operation, the equipment shall be repaired by qualified personnel prior to its next use or be withdrawn from service and tagged out of service. 4.1.5 Management shall ensure that only approved apparatus. such as torches, manifolds, regulators or pressure-reducing valves, and acetylene generators, are used. 4.1.6 Management shall ensure that all individuals involved in the hot work operations, including contractors, are familiar with the provisions of this standard. 4,1.6.1 Individuals involved in hot work operations shall be trained in the safe operation of their equipment and in the safe use of the process. 4.1,6,2 Individuals involved in hot work operations shall have an awareness of the inherent risks involved and understand the emergency procedures in the event...
