Preface
This new edition of CSA Standard B44, Safety Code for Elevators, Dumbwaiters, Escalators, and Moving Walks, supersedes previous editions published in 1938, 1960 and 1966.
The Code was originally prepared to meet a desire for uniform legislation throughout the various provinces and to replace the legislation previously existing in Canada which had proved inadequate in view of the then prevailing elevator practices. Its primary purpose is to provide reasonable safety for those persons who come in contact with elevators, dumbwaiters, and escalators, by establishing minimum standards for design, installation, and maintenance and for adoption by provincial authorities throughout Canada. It is also intended as a standard reference for the use of architects, consulting engineers, elevator manufacturers, and owners.
In the preparation of this fourth edition, the American Standard Code for Elevators, (ANSI A17.1), and changes thereto, have been carefully studied and grateful acknowledgement is given to this organization for the material used.
Major changes in this fourth edition are the inclusion of new sections on moving walks, and the temporary use of permanent elevators. Also, the section on dumbwaiters has been rearranged in order to avoid numerous references to other parts of the Code, thereby making it more complete in itself. All other technical changes between editions, some of which appeared in three published Supplements to the third edition, are indicated by vertical lines in the left hand margins of pertinent pages.
This Code was prepared by the Committee on Elevator Safety Code under the jurisdiction of the Sectional Committee on Safety Codes, and was formally approved by these Committees and the CSA Standards Policy Board.
