1.1  General

This Standard includes requirements for the safe operation of various types of suspended equipment (see Figure 1) used to gain access to interior or exterior, or both, sides, ceilings and soffits of buildings or structures. Much of the equipment referred to in this Standard is designed, installed, inspected, and tested in accordance with CAN/CSA-Z271 and other referenced standards. This Standard does not apply to crane-suspended platforms or baskets (see CSA Z150), multi-point bridge platforms, or hanging scaffolds.

Note: While this Standard is not intended to cover equipment design and building provisions, both CAN/CSA-Z271 and this Standard contain necessary information for design and operation of suspended equipment.

1.2  Application

This Standard specifies the safety requirements for suspended equipment that is normally used for, but whose use is not limited to, window cleaning, exterior building cleaning, painting, application of sealants and insulation, brickwork, repointing, renovations, inspection, and related building/structure maintenance.
