The design and construction of electrical equipment for elevators and escalators presents complex requirements in the application of industrial control equipment and elevator equipment. With the need to have identical Canadian and U.S. requirements for this type of equipment, the applicable portions of CSA C22.2 No. 14 and UL 508 were reviewed and adapted to elevator equipment.
Highlights of B44.1:
- Provides guidance to reduce the risk of injury and potential damage to property from fire and electrical shock
- Harmonized standard combining applicable portions from CSA C22.2 No. 14 and UL 508 adapted for elevator equipment
- Harmonized guidelines enable manufacturers to have their products certified by an approved testing laboratory in Canada or the United States and to have the certification ratified for acceptance in either country
- Indented to reduce the risk of injury to persons and damage to property from fire and electrical shock
This is the third edition of ASME A17.1/CSA B44, Safety Code for Elevators and Escalators. It replaces the previous edition of ASME A17.1/CSA B44, published in 2010, and the previous editions of CSA B44, published in 2007, 2004, 2000, 1994, 1990, 1985, 1975, 1971, 1966, 1960, and 1938.
This Code is the result of a joint effort by the CSA B44 Technical Committee on the Elevator Safety Code and the ASME A17 Committee on Elevators and Escalators to harmonize the provisions of CSA B44 and ASME A17.1. This edition of ASME A17.1/CSA B44 consists of the complete ASME A17.1 Code, with additional requirements applicable only in Canadian jurisdictions. These Canadian requirements are prefaced in the body of the Code by the following: In jurisdictions enforcing the NBCC. . .
CSA B44 was originally developed to facilitate the implementation of uniform legislation across Canada and to replace the existing legislation, which had proved inadequate for prevailing elevator practices. The primary purpose of the Code is to establish minimum requirements, suitable for adoption by regulatory authorities throughout Canada, for the design, installation, and maintenance of elevators, escalators, dumbwaiters, moving walks, and material lifts. It is also intended as a standard reference for architects, consulting engineers, elevator manufacturers, and building owners.
1.1.1 Equipment Covered by This Code
This Code covers the design, construction, operation, inspection, testing, maintenance, alteration, and repair of the following equipment and its associated parts, rooms, spaces, and hoistways, where located in or adjacent to a building or structure (see 1.2):
(a) hoisting and lowering mechanisms, equipped with a car, that move between two or more landings. This equipment includes, but is not limited to elevators (see 1.3).
(b) power-driven stairways and walkways for carrying persons between landings. This equipment includes, but is not limited to escalators and moving walks (see 1.3).
(c) hoisting and lowering mechanisms equipped with a car that serves two or more landings and is restricted to the carrying of material by its limited size or limited access to the car. This equipment includes, but is not limited to dumbwaiters and material lifts; it does not include vertical reciprocating conveyors (see 1.3).
1.1.2 Equipment Not Covered by This Code
Equipment not covered by this Code includes, but is not limited to, the following:
(a) personnel hoists within the scope of ANSI A10.4 and CSA-Z185
(b) material hoists within the scope of ANSI A10.5 and CSA-Z256
(c) platform lifts and stairway chairlifts within the scope of ASME A18.1, CSA B355, and CSA B613
(d) manlifts within the scope of ASME A90.1 and CSA B311, and in jurisdictions enforcing NBCC Special Purpose Personnel Elevators (ASME A17.1, Section 5.7)
(e) mobile scaffolds and towers; platforms within the scope of ANSI/SIA A92 and CSA-B354
(f) powered platform and equipment for exterior and interior building maintenance within the scope of ASME A120.1 and CSA-Z271
(g) conveyors and related equipment within the scope of ASME B20.1
(h) cranes, derricks, hoists, hooks, jacks, and slings within the scope of ASME B30, CSA Z150, CSA B167, CSA Z202, and CSA Z248
(i) industrial trucks within the scope of ASME B56 and CSA B335
(j) portable equipment, except for portable escalators, that are covered by 6.1
(k) tiering or piling machines used to move material to and from storage located and operating entirely within one story
(l) equipment for feeding or positioning material at machine tools, printing presses, etc.
(m) skip or furnace hoists
(n) wharf ramps
(o) amusement devices
(p) stage and orchestra lifts
(q) lift bridges
(r) railroad car lifts and dumpers
(s) mechanized parking garage equipment
(t) line jacks, false cars, shafters, moving platforms, and similar equipment used for installing an elevator
(u) platform-type elevators installed on board a marine vessel
(1) A maritime, industrial-use device with no car enclosure. Controls are located outside of the hoistway. Typically utilizes elevator-type rail systems and elevator-type interlock systems.
(2) Not a platform lift within the scope of A18.1.
(v) dock levelers (freight platform lifts) having a rise of 500 mm (20 in.) or less
(w) in Canadian jurisdictions, devices having a rise of 2 000mm(79 in.) or less and used only for the transfer of materials or equipment
(x) in jurisdictions enforcing NBCC, mine elevators within the scope of 5.9
