|OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules.

This Subpart applies to all . . . ladders used in construction . . .Section 1926.1053 (Ladders) begins with the following provision:
(a) General. The following requirements apply to all ladders as indicated, including job-made ladders.The section contains requirements for three different types of ladders -- self-supporting portable ladders, non-self-supporting portable ladders, and fixed ladders. In §1926.1050(b), the standard defines a portable ladder as:
a ladder that can be readily moved or carried.The ladder you describe cannot be moved without dismantling the securing system at the top and bottom of the ladder. Therefore, it is not a portable ladder.
A ladder that cannot be readily moved or carried because it is an integral part of the building or structure.The ladder you describe meets the definition of a fixed ladder because it becomes an "integral part of the . . .structure" once it is installed, and then "cannot be readily moved or carried." Therefore, it must meet the requirements in Subpart X applicable to fixed ladders.
Non-self-supporting ladders shall be used at an angle such that the horizontal distance from the top support to the foot of the ladder is approximately one-quarter of the working length of the ladder (the distance along the ladder between the foot and the top support).There is another provision, §1926.1053(b)(5)(iii), that specifies the required angle for fixed ladders:
Fixed ladders shall be used at a pitch no greater than 90 degrees from the horizontal, as measured to the back side of the ladder.Since the cable ladder you describe is considered a fixed ladder, §1926.1053(b)(5)(iii) applies with respect to the required angle.
Ladders shall have nonconductive side rails if they are to be used where the employee or the ladder could contact exposed energized electrical equipment, except as provided by §1926.951(c)(1) of this part.29 CFR 1926.951(c)(1) is a provision within Subpart V (Power Transmission and Distribution), which allows conductive ladders to be used when doing a particular type of power transmission and distribution construction work.1 It states:
Portable metal or conductive ladders shall not be used near energized lines or equipment except as may be necessary in specialized work such as in high voltage substations where nonconductive ladders might present a greater hazard than conductive ladders . . .The metal cable ladder is considered a conductive ladder (with conductive side rails). However, §1926.951(c)(1) is applicable only where the work being done is power transmission and distribution construction work.
