§3281. Definitions.

(a) For the purpose of Articles 5 and 6, certain terms are defined as follows, except for Appendix D:

* * * * *

Controlled Descent Apparatus (CDA). A CDA is a device used by window cleaners to achieve a controlled descent during window cleaning operations. The descent control capability of the CDA is derived by frictional forces developed when a line(s) passes over and/or around and/or through fixed members of the friction device designed to be readily controlled by the window cleaner.

* * * * *

Danger Zone. The "Danger Zone" is the area within six feet of the edge of a building’s roof or protruding ledge. This area is only considered a "Danger Zone" if the roof or protruding ledge is not provided with a guardrail that stands 42 inches in height, a 42 inch high parapet, or a combination thereof.

* * * * *

Height of Suspension. Where the term height of suspension is used in Articles 5 and 6 of these Orders, it refers to the specific suspension height on buildings or structures to the level below. To determine the suspension height, the distance is measured from the highest point of suspension for the building maintenance equipment (outrigger beam, davit, or roof carriage) to the level below. If the building maintenance equipment is suspended from roof tie-backs, the highest point is measured from the top of the parapet or roof’s edge. The lowest measurement point at the level or ground below includes, but is not limited to, roofs, sidewalks, streets, parking garages, and driveways.

* * * * *

Manual Boatswain’s Chair. A suspended seat for designed to accommodate one person, suspended by a single line or tackle, which is designed to be raised and lowered by the user. in a sitting position.

A. A building does not have established window cleaning system or procedures meeting the requirements specified in Articles 5 and 6, or

B. A building’s original window cleaning procedures prepared in accordance with the requirements in Articles 5 and 6 have been changed because of building modifications, or

C. A building has extreme architectural features, which require the use of complex rigging or equipment, or a building that uses rigging or equipment not covered by these Orders.

2. An OPOS shall be developed by a person(s) with knowledge in the design, installation and use of building maintenance equipment (i.e. possessing Scaffold Inspection Testing certification as specified in Section 3296). The OPOS shall be written in manner that can be readily understood by employers. An OPOS that requires structural modifications to the building or existing building maintenance equipment shall have such modifications designed by a mechanical, structural or civil engineer currently registered in the State of California with experience in the design and installation of such equipment.

3. An OPOS shall be developed which at a minimum shall contain the elements of Appendix A of this Article.
