These platforms are movable, but they are not elevating. Examples of this type of work platform are those that are positioned and supported by a crane, hoist, or lift truck. Platforms supported by other equipment (lift truck supported, and crane or hoist supported): A platform that is elevated by another piece of equipment is not an elevating work platform because the platform itself is not designed to be capable of elevating.Mast climbers that provide access to the face of a building, and that can be repositioned vertically as work proceeds, are also included in this group. If the platform travels under power when operated by controls on the work platform it is termed "self-propelled." There are two types of self-propelled units those that are boom-supported, and other designs, such as self-propelled scissor lifts.Īlternatively, if an elevating work platform is moved by hand or is attached to the deck of a powered vehicle, it is called a "portable elevating work platform." There are a range of types of portable elevating work platforms in use, from elevating equipment mounted on service trucks, to compressed gas power lifts that are moved by hand. Elevating work platforms: An elevating work platform is one that self-elevates, and includes design features for lateral mobility (travel).Suspended staging (permanent powered platforms, swing stages, and boatswain's chairs): These are all movable platforms that are supported by line(s) from a building or structure, and can be repositioned vertically during use.The different types of movable work platforms shown in the chart can be discussed in three groups: suspended staging, elevating work platforms, and platforms supported by other equipment. Movable work platforms: A movable work platform is a platform that can be moved, manually or by power, in either the vertical or horizontal direction, or both, and covers a range of types of equipment. The following explanations are intended to assist the reader. The purpose of this guideline is to provide a chart to show the various types of work platforms covered by Part 13 of the Regulation, and a brief explanation of some types of movable platforms.Ĭonfusion sometimes arises about the differences between some of the terms in the chart, particularly related to movable work platforms. "work platform" means an elevated or suspended temporary work surface used for supporting workers and includes a scaffold and boatswain's chair. "swing stage" means a work platform that is raised and lowered by manual or powered hoisting equipment, supported by 2 or more suspension lines "self-propelled" means the capability of an elevating work platform to travel under power with the primary controls on the work platform "scaffold" means any temporary elevated work platform and its supporting structure used for supporting workers, materials or equipment (b) is not permanently installed on or attached to a building or structure "portable powered platform" means a movable work platform that (b) is permanently installed on or attached to a building or structure (a) is raised or lowered by other than manual means, and "permanent powered platform" means a movable work platform that "movable work platform" means a work platform that can be re-positioned during the course of the work "elevating work platform" means a movable work platform that self-elevates to overhead work locations "boatswain's chair" also known as a bosun's chair, means a seat attached to a suspended rope designed to accommodate one person in a sitting position "boom-supported" means supported by an elevating device that telescopes, articulates, rotates or extends relative to the machine base or vehicle, so that the platform can be positioned completely beyond the base Section 13.1 of the OHS Regulation (" Regulation") states: Issued JanuRevised MaEditorial Revision June 30, 2021 G13.32-1 Work in high-risk situations - Inspection and testing requirements Guidelines Part 13 Division 1 - General G13.32 Prior permission - Platform use in high risk situations G13.28(2) Safe work procedure acceptable to the Board to prevent two-blocking in pile driving and similar applications G13.23(1) Inspection and certification of elevating work platforms G13.19 When and how to ground metal scaffold DIVISION 5 - MOVABLE WORK PLATFORMS G13.8 General requirements - Chair design DIVISION 4 - SCAFFOLDS G13.4 Ladder ratings and selection DIVISION 3 - WORK PLATFORMS G13.2(1)-3 Training requirements for operators of elevating work platforms G13.2(1)-2 Application of CSA and ANSI standards for suspended stages Forestry Operations and Similar Activities Diving, Fishing and Other Marine Operations Ladders, Scaffolds and Temporary Work Platforms Personal Protective Clothing and Equipment Noise, Vibration, Radiation and Temperature Occupational Health and Safety Regulation
