    (i)    Floor openings, not including hoistway openings, shall be guarded with standard railing or with fixed safety covers with flush hinges.

     

    (ii)    When an overhead obstruction prevents the use of standard railing, the top of the railing shall be constructed not more than ten inches below the overhead obstruction.

     

    (iii)     Removable or hinged railings or a substantial chain or wire rope section shall be installed when operations prevent installation of standard railing or fixed safety covers with flush hinges.

     

    (b)   Work below floor openings.

     

    Where  employees  are  required  to  work  below  a  floor  opening, toeboards shall be installed.

     

    (c)   Safety covers.

     

    When a safety cover is used to protect an opening, the unused sides of the opening shall be guarded when the cover is raised.

     

    (d)  Guarding manholes, handholes, gratings and excavations.

     

     

    Barriers, barricades or standard guard railings shall be provided for guarding open manholes, handholes, gratings or excavations and shall be visible at all times.

    (2)   Floor holes - guarding.

    (a)    Every floor hole into which employees can accidentally walk shall be guarded by either:

    (i)   A standard railing and toeboard on all exposed sides, or

    (ii)      A fixed, hinged floor hole cover of substantial strength and construction. While the cover is not in place, the floor hole shall be attended by an employee designated by the employer or shall be guarded by a removable standard railing.

    (b)     Every floor hole into which employees cannot accidentally walk (on account of fixed machinery, equipment, or walls) shall be protected by a cover that leaves no openings more than one inch wide. The cover shall be securely held in place to prevent tools or materials from falling through.

    (3)   Wall openings and holes, including chute openings.

    (a)   Wall opening - guarding.

    (i)    Wall openings shall be guarded by standard railings and toeboards, or with doors or gates or substantial screens which shall extend to a minimum height of forty-two inches measured from the floor or platform level.

    (ii)    When the top of the wall openings, protected by a railing, prevents installation of standard guard railing, the top rail shall be not be more than ten inches below the top of the wall opening.

    (b)   Wall hole - guarding.

    Where there is a hazard of materials falling through a wall hole, and the lower edge of the near side of the hole is less than four inches above the floor, and the far side of the hole more than five feet above the next lower level, the hole shall be guarded by a toeboard, or an enclosing

    screen either of solid construction, or as specified in rule 4123:1-5-99 of the Administrative Code.

    (c)   Openings used for unloading materials - guarding.

    (i)    Openings used for unloading material into chutes, hoppers or bins when not in use, shall be guarded.

    (ii)   Area at discharge end of chutes:

    The area at the discharge end of chutes shall be guarded if employees are required to work in, or pass through the area. If the chute discharges into a bin, conveyor, truck, railroad car, or other container, guarding shall not be required, but warning signs of conspicuous and easily read style shall be posted to warn employees when there is a hazard from falling, flying, moving or sliding objects.

    (4)   Working pits.

    Working pits shall be guarded when not in use.

    (5)   Open vats, open soaking pits and open tanks.

    (a)   Sides of such vats, soaking pits, and tanks, containing injurious chemicals or other materials, shall extend to a height of not less than thirty-six inches above the working floor level or shall be guarded by standard guard railing. Employees shall not be required to work over such vats, soaking pits and tanks except on elevated runways, platforms and walkways (see paragraph (D)(1) of this rule).

    (b)   This shall not apply to open vats, soaking pits and open tanks designated as restricted areas where product is handled by conveyor or cab-controlled overhead crane.

    (6)   Galvanizing tanks.

    Galvanizing tanks shall have a minimum height of thirty inches. At such height the wall thickness or bench shall be no less than thirty-two inches in width. For each increase in height of one inch the wall thickness or bench may be reduced by four inches (see appendix to this rule).
