3. A ladder with a defect must be either properly repaired or destroyed.

4.3 Fixed Ladders

Fixed ladders are an integral part of a building or structure and cannot be readily moved or carried. Types include side-step and through
fixed ladders. A side-step fixed ladder requires a person getting off at the top to step to the side of the ladder side rails to reach the
landing. A through fixed ladder requires a person getting off at the top to step between the side rails of the ladder to reach the landing.

4.3.1 General Requirements

1. The minimum design live load must be a single concentrated load of 200 pounds.

2. The number and position of additional concentrated live-load units of 200 pounds each as determined from anticipated usage of the ladder must be
considered in the design.

3. The live loads imposed by persons occupying the ladder must be considered to be concentrated at such points as will cause the maximum stress in the
structural member being considered.

4. The weight of the ladder and attached appurtenances together with the live load must be considered in the design of rails and fastenings.

5. For fixed ladders consisting of wood side rails and wood rungs or cleats, used at a pitch in the range 75 degrees to 90 degrees, and intended for use by
no more than one person per section.

6. All rungs must have a minimum diameter of three-fourths inch for metal ladders and a minimum diameter of 1 1/8 inches for wood ladders.

7. The distance between rungs, cleats, and steps must not exceed 12 inches and must be uniform throughout the length of the ladder.

8. The minimum clear length of rungs or cleats must be 16 inches.

9. Rungs, cleats, and steps must be free of splinters, sharp edges, burrs or projections which may be a hazard.

10. The rungs of an individual-rung ladder must be so designed that the foot cannot slide off the end.

11. Side rails which might be used as a climbing aid must be of such cross sections as to afford adequate gripping surface without sharp edges, splinters,
or burrs.

12. Fastenings must be an integral part of fixed ladder design.

13. All splices and connections must have smooth transition with original members and with no sharp or extensive projections.

14. Adequate means must be employed to protect dissimilar metals from electrolytic action when such metals are joined.

15. All welding must be in accordance with the “Code for Welding in Building Construction” (AWSD1.0-1966).

16. Ladder safety devices may be used on ladders over 20 feet in unbroken length in lieu of cage protection. No landing platform is required in these
cases. All ladder safety devices such as those that incorporate lifebelts, friction brakes, and sliding attachments must meet the design requirements of
the ladders.

17. The perpendicular distance from the centerline of the rungs to the nearest permanent object on the climbing side of the ladder must be 36 inches for a
pitch of 76 degrees, and 30 inches for a pitch of 90 degrees, with minimum clearances for intermediate pitches varying between these two limits in
proportion to the slope.

18. Ladders without cages or wells. A clear width of at least 15 inches must be provided each way from the centerline of the ladder in the climbing space,
except when cages or wells are necessary.

19. The distance from the centerline of rungs, cleats, or steps to the nearest permanent object in back of the ladder must be not less than 7 inches,
except that when unavoidable obstructions are encountered, minimum clearances must be provided.

20. The distance from the centerline of the grab bar to the nearest permanent object in back of the grab bars must be not less than 4 inches. Grab bars
must not protrude on the climbing side beyond the rungs of the ladder which they serve.

21. The step-across distance from the nearest edge of ladder to the nearest edge of equipment or structure must be not more than 12 inches, or less than 2
1/2 inches.

22. The side rails of through or side-step ladder extensions must extend 3 1/2 feet above parapets and landings. For through ladder extensions, the rungs
must be omitted from the extension and must have not less than 18 nor more than 24 inches clearance between rails. For side-step or offset fixed ladder
sections, at landings, the side rails and rungs must be carried to the next regular rung beyond or above the 3 1/2 feet minimum.

23. Grab bars must be spaced by a continuation of the rung spacing when they are located in the horizontal position. Vertical grab bars must have the same
spacing as the ladder side rails. Grab-bar diameters must be the equivalent of the round-rung diameters.

24. The preferred pitch of fixed ladders must be considered to come in the range of 75 degrees and 90 degrees with the horizontal. Fixed ladders must be
considered as substandard if they are installed within the substandard pitch range of 60 and 75 degrees with the horizontal. This substandard pitch range
must be considered as a critical range to be avoided, if possible.

25. Counterweighted hatch covers must open a minimum of 60 degrees from the horizontal. The distance from the centerline of rungs or cleats to the edge of
    the hatch opening on the climbing side must be not less than 24 inches for offset wells or 30 inches for straight wells. There must not be protruding
    hazards within 24 inches of the centerline of rungs or cleats; any such hazards within 30 inches of the centerline of the rungs or cleats must be
    fitted with deflector plates placed at an angle of 60 degrees from the horizontal.

4.3.2 Cages and Wells

1. Cages or wells must be provided on ladders of more than 20 feet to a maximum unbroken length of 30 feet.
2. Cages must extend a minimum of 42 inches above the top of landing, unless other acceptable protection is provided.
3. Cages must extend down the ladder to a point not less than 7 feet nor more than 8 feet above the base of the ladder, with bottom flared not less than 4
   inches, or portion of cage opposite ladder must be carried to the base.
4. Cages must not extend less than 27 nor more than 28 inches from the centerline of the rungs of the ladder. Cage must not be less than 27 inches in
   width. The inside must be clear of projections. Vertical bars must be located at a maximum spacing of 40 degrees around the circumference of the cage;
   this will give a maximum spacing of approximately 9 1/2 inches, center to center.
5. Ladder wells must have a clear width of at least 15 inches measured each way from the centerline of the ladder. Smooth-walled wells must be a minimum
   of 27 inches from the centerline of rungs to the well wall on the climbing side of the ladder. Where other obstructions on the climbing side of the
   ladder exist, there must be a minimum of 30 inches from the centerline of the rungs.

4.3.3 Landing Platforms

1. When ladders are used to ascend to heights exceeding 20 feet (except on chimneys), landing platforms must be provided for each 30 feet of height or
   fraction thereof, except where no cage, well, or ladder safety device is provided, landing platforms must be provided for each 20 feet of height or
   fraction thereof. Each ladder section must be offset from adjacent sections. Where installation conditions (even for a short, unbroken length) require
   that adjacent sections be offset, landing platforms must be provided at each offset.
2. Where a person has to step a distance greater than 12 inches from the centerline of the rung of a ladder to the nearest edge of structure or equipment,
   a landing platform must be provided. The minimum step-across distance must be 2 1/2 inches.
3. All landing platforms must be equipped with standard railings and toeboards, so arranged as to give safe access to the ladder. Platforms must be not
   less than 24 inches in width and 30 inches in length.
4. One rung of any section of ladder must be located at the level of the landing laterally served by the ladder. Where access to the landing is through
   the ladder, the same rung spacing as used on the ladder must be used from the landing platform to the first rung below the landing.

4.3.4 Maintenance

1. All ladders must be maintained in a safe condition. All ladders must be inspected regularly, with the intervals between inspections being determined by
   use and exposure.
2. Metal ladders and appurtenances must be painted or otherwise treated to resist corrosion and rusting when location demands.
3. Wood ladders, when used under conditions where decay may occur, must be treated with a nonirritating preservative, and the details must be such as to
   prevent or minimize the accumulation of water on wood parts.
4. When different types of materials are used in the construction of a ladder, the materials used must be so treated as to have no deleterious effect one
   upon the other.
