     Responsible party
     Fire watch
    A. The Thirty Five Foot Rule
    NFPA 5IB “STANDARD FOR FIRE
    PREVENTION DURING WELDING,
    CUTTING, AND OTHER HOT WORK.”

    “ Section 3-3.2(b)
    “Where combustible materials, such as paper
    clippings, wood shavings, or textile fibers, are on
    the floor, the floor shall be swept clean for a
    radius of 35 ft. Combustible floors shall be kept
    wet, be covered with damp sand, or be protected
    by noncombustible or fire-retardant shields.”
    Section 3-3.2(c)
    “All combustibles shall be relocated at least 35 ft
    horizontally from the work site. If relocation is
    impractical, combustibles shall be protected with fire-
    retardant covers or otherwise shielded with metal or fire-
    retardant guards or curtains. Edges of covers at the floor
    shall be tight to prevent sparks from going under them,
    including where several covers overlap when protecting a
    large pile.”
     Section 3-3.2(d)
    “Openings or cracks in walls, floors, or ducts within 35 ft of the
    site shall be tightly covered with fire-retardant or noncombustible
    material to prevent the passage of sparks to adjacent areas.”
    STANDARD OF CARE

     American National Standard, ANSI Z49.1


     “Safety in Welding, Cutting, and Allied Processes”
     Who wrote it?
     Important parts?
     Also: OSHA General Industry Standards 29 CFR 1910 Subpart
    Q, “Welding, Cutting and Brazing”
    OSHA

     1910.252(a)(1)(i)
     FireHazards: If the object to be welded or cut cannot readily
    be moved, all movable fire hazards in the vicinity shall be
    taken to a safe place.
    OSHA

     1910.252(a)(1)(ii)
     Guards: If the object to be welded or cut cannot be moved and
    if all the fire hazards cannot be removed, then guards shall be
    used to confine the heat, sparks, and slag, and to protect the
    immovable fire hazards.
    OSHA

     1910.252(a)(1)(iii)
     Restrictions: If the requirements stated in paragraphs (a)(1)(i)
    and (a)(1)(ii) of this section cannot be followed then welding
    and cutting shall not be performed.
    OSHA

     1910.252(a)(2)(i)
     Combustible material: Wherever there are floor openings or
    cracks in the flooring that cannot be closed, precautions shall
    be taken so that no readily combustible materials on the floor
    below will be exposed to sparks which might drop through the
    floor. The same precautions shall be observed with regard to
    cracks or holes in walls, open doorways and open or broken
    windows.
    OSHA

     1910.252(a)(2)(ii)
     Fire extinguishers: Suitable fire extinguishing equipment shall
    be maintained in a state of readiness for instant use. Such
    equipment may consist of pails of water, buckets of sand, hose
    or portable extinguishers depending upon the nature and
    quantity of the combustible material exposed.
    B. The Responsible Party
    WHO IS THE RESPONSIBLE PARTY

    “The owner shall designate a person who shall be responsible for


    the fire prevention program and who shall ensure that it is carried

     Annex A – Explanatory Material
