CAN/CSA-Z259.2.3:16 (ISO 22159:2007, MOD)

This is the third edition of CAN/CSA-Z259.2.3, Descent devices, which is an adoption, with Canadian deviations, of ISO (International Organization for Standardization) Standard 22159 (first edition, 2007-05-15), entitled Personal equipment for protection against falls — Descending devices. The title has been changed for the CSA Group Standard to ensure continuity with previous editions of this Standard. This Standard supersedes the previous edition published in 2012 as CAN/CSA-Z259.2.3 (adopted ISO 22159:2007). For brevity, this Standard will be referred to as “CAN/CSA-Z259.2.3” throughout. The ISO Standard was developed by ISO/TC 94/SC 4. The adoption of this ISO Standard as a National Standard of Canada is an important step in the acceptance of design data for safety equipment traded on a worldwide basis. The CSA Technical Committee on Fall Protection determined that ISO 22159 could be used as the basis of the new edition of CAN/CSA-Z259.2.3 as it most closely reflected the committee’s perspective on descent control devices and it fosters international harmonization. In the second edition of CAN/CSA-Z259.2.3, only Type 1 and Type 3 descending devices, as classified by ISO 22159, were deemed suitable for use in the Canadian marketplace. In this, the third edition of the Standard, the CSA Technical Committee on Fall Protection has recognized the increasing use of all 6 types of descending devices in Canada and is accepting Types 1 through 6 for the Canadian marketplace. This Standard was reviewed for Canadian adoption by the CSA Technical Committee on Fall Protection, under the jurisdiction of the CSA Strategic Steering Committee on Occupational Health and Safety, and has been formally approved by the Technical Committee. This Standard has been approved as a National Standard of Canada by the Standards Council of Canada.
