CSA Z259.2.4-12

Abstract

This Standard specifies design, testing, and marking requirements for manufactured fall arresters and fixed vertical rigid rails that are used on a vertical or slope plane. "Vertical plane" means an angle of not more than 15&#176; from the vertical, which prevents the worker from leaning back. <br>Thequipment specified in this Standard is intended for use where there is a danger of falling from heights. In the event of fall, the fall arrester will lock on the fixed vertical rigid rail to arrest the fall. <br>This Standard does not cover work positioning and horizontal travel systems. <br>In CSA standards, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the standard. <br>accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. <br>Notes to tables and figures are considered part of the table or figure and may be written as requirements. <br>Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application. <br>The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
