Cal. Code Regs. tit. 8, § 3276
(b) Definitions.
Extension Ladder. An extension ladder is a non-self-supporting portable ladder adjustable in length. It consists of two or more sections traveling in guides or brackets so arranged as to permit length adjustment. Its size is designated by the sum of the lengths of the sections measured along the side rails.
Extension Trestle Ladder. An extension trestle ladder is a self-supporting portable ladder, adjustable in length, consisting of a trestle ladder base and a vertically adjustable single ladder, with suitable means for locking the ladders together. The size is designated by the length of the trestle ladder base.
Ladders. A ladder is an appliance usually consisting of two side rails joined at regular intervals by crosspieces called steps, rungs, or cleats, on which a person may step in ascending or descending.
Sectional Ladder. A sectional ladder is a non-self-supporting portable ladder, nonadjustable in length, consisting of two or more sections of ladder so constructed that the sections may be combined to function as a single ladder. Its size is designated by the overall length of the assembled sections.
Side-Rolling Ladder. A side-rolling ladder is a semifixed ladder, nonadjustable in length, supported by attachments to a guide rail, which is generally fastened to shelving, the plane of the ladder being also its plane of motion.
Single Ladder. A single ladder is a non-self-supporting portable ladder, nonadjustable in length, consisting of but one section. Its size is designated by the overall length of the side rail.
Single-Rail Ladder. A ladder with rungs, cleats, or steps mounted on a single-rail instead of the normal two rails used on most other ladders.
Special-Purpose Ladder. A special-purpose ladder is a portable ladder which represents either a modification or a combination of design or construction features in one of the general-purpose types of ladders previously defined, in order to adapt the ladder to special or specific uses.
Step Ladder. A step ladder is a self-supporting portable ladder, nonadjustable in length, having flat steps and a hinged back. Its size is designated by the overall length of the ladder measured along the front edge of the side rails.
Step stool (ladder type). A self-supporting, foldable, portable ladder, nonadjustable in length, 32 inches or less in length, with flat steps and without a pail shelf, designed so that the ladder top cap as well as all steps can be climbed on. The side rails may extend above the top-cap but such extension is not considered as part of the step stool length.
Trestle Ladder. A trestle ladder is a self-supporting portable ladder, nonadjustable in length, consisting of two sections hinged at the top to form equal angles with the base. The size is designated by the length of the side rails measured along the front edge.
Trolley Ladder. A trolley ladder is a semifixed ladder, nonadjustable in length, supported by attachments to an overhead track, the plane of the ladder being at right angles to the plane of motion.
(c) Design and Construction.
(1) Portable wood ladders placed in service after January 7, 2011 shall meet the design and construction requirements of ANSI A14.1-2007, American National Standard for Ladders -- Wood Safety Requirements, which is hereby incorporated by reference. Portable wood ladders placed in service on or before January 7, 2011, shall meet the design and construction requirements of the ANSI A14.1 standard in effect at the time such ladders were placed in service.
Exception: Portable job-made cleat ladders that are designed and constructed in accordance with the requirements of Section 1676 of the Construction Safety Orders.
(d) Selection.
(1) Ladders shall be selected and their use restricted to the purpose for which the ladder is designed. Single-rail ladders shall not be used.
(B) Portable ladders are generally designed for one-person use to meet the requirements of the person, the task, and the environment. When selecting a ladder for use, consideration shall be given to the ladder length or height required, the working load, the duty rating, worker position to the task to be performed, and the frequency of use to which the ladder will be subjected.
Note: Subsection (e)(16)(D) prohibits the use of ladders that exceed specified maximum lengths.
(2) Ladders shall be used according to the following duty classifications:
Duty Rating
Ladder Type
Working Load (Pounds)
Special Duty
IAA
375
Extra Heavy-Duty
IA
300
Heavy-Duty
I
250
Medium-Duty
II
225
Light-Duty
III
200
(e) Care, Use, Inspection and Maintenance of Ladders.
(5) Surface Coatings.
Wood ladders shall not be painted with other than a transparent material.
(8) Top Support. The top of non-self-supporting ladders such as single and extension ladders shall be placed with the two rails supported equally, unless a single support attachment is provided and used.
The top rest for portable rung and cleat ladders shall be reasonably rigid and shall have ample strength to support the applied load.
(11) Access to Landings. When portable ladders are used for access to an upper landing surface, the side rails shall extend not less than 36 inches above the upper landing surface to which the ladder is used to gain access; or when such an extension is not possible, then the ladder shall be secured at its top to a rigid support that will not deflect, and a grasping device, such as a grab-rail, shall be provided to assist employees in mounting and dismounting the ladder. In no case shall the extension be such that ladder deflection under a load would, by itself, cause the ladder to slip off its support.
Exception No. 1: A grasping device such as a grab-rail is not required where the employee is protected by personal fall protection system in accordance with Article 24 of the Construction Safety Orders, Article 36 of the High-Voltage Electrical Safety Orders, Article 12 of the General Industry Safety Orders, or Article 1 of the Telecommunication Safety Orders. Operations or conditions not specifically covered by Article 36 of the High-Voltage Electrical Safety Orders, Article 12 of the General Industry Safety Orders, or Article 1 of the Telecommunication Safety Orders shall comply with the fall protection provisions of Article 24 of the Construction Safety Orders.
Exception No. 2: The provisions of this subsection do not apply to emergency rescue and emergency rescue training operations where it is not practical to extend a portable ladder 36 inches or more above the landing surface.
(15) Climbing and Working on Ladders.
(C) When ascending or descending a ladder, the user shall face the ladder and maintain contact with the ladder at three-points at all times.
Note: Contact with the ladder at three points means two feet and one hand, or two hands and one foot which is safely supporting the user's weight.
(E) Employees shall not sit, kneel, step or stand on the pail shelf, topcap or the step below the topcap of a step ladder.
Exception: Employees may stand on the step below the topcap provided it is located 18 inches under the topcap.

(18) Electrical Hazards. Non-conductive ladders shall be used in locations where the ladder or user may contact unprotected energized electrical conductors or equipment. Conductive ladders shall be legibly marked with signs reading “CAUTION--Do Not Use Around Electrical Equipment,” or equivalent wording.
Note: Additional requirements for working in proximity to energized electrical equipment can be found in Article 37 of the Electrical Safety Orders.
(f) Employee Training. Before an employee uses a ladder, the employee shall be provided training in the safe use of ladders, unless the employer can demonstrate that the employee is already trained in ladder safety as required by this subsection. Supervisors of employees who routinely use ladders shall also be provided ladder safety training, unless the employer can demonstrate that the supervisor is already trained in ladder safety as required by this subsection. The training may be provided as part of the employer's Injury and Illness Prevention Program required by Section 3203. The training shall address the following topics, unless the employer can demonstrate a topic is not applicable to the safe use of ladders in the employer's workplace.
