Preface 

This is the second edition of CSA Z259.17, Selection and use of active fall-protection equipment and systems . This Standard supersedes the previous edition published in 2016. The purpose of this Standard is to provide criteria for the safe selection and use of fall-protection equipment and systems. 

Significant changes in this edition include the following: 

a) information included on selection and use of post-fall rescue equipment, plans, and procedures.; 

b) enhanced the emergency and rescue plan identification requirements; 

c) equations are now provided for required clearance - vertical lifeline; 

d) new annex on examples of improper use and assembly of equipment, systems and components;

Scope 

1.1 This Standard specifies requirements for the selection, use, and application of active fall-protection equipment and systems as well as information on selection and use of post-fall rescue equipment, plans, and procedures. 

1.2 The purpose of this Standard is to provide criteria and considerations for the safe selection and use of active fall-protection equipment and systems. 

1.3 The selection and use of fall-protection systems as part of a fall-protection program that may include such elements as hazard assessment, work methods, purchasing, practices, training, maintenance, and inspection intended to minimize the risks involved. 

1.4 The clauses of this Standard are intended to reduce risks, which are inherent in all active fall-protection systems. 

1.5 This Standard references personal fall-protection system (PFPS) components that conform to the requirements of the CSA Z259 Series of Standards or an equivalent. 

1.6 This Standard does not cover requirements for a) design and performance of fall-protection systems or components; and Note: For design and performance requirements refer to the applicable fall protection Standard (see CSA Z259 series). b) selection and use of passive fall-protection systems such as temporary guardrails or safety net systems. This Standard is not intended to replicate or replace other Standards covered by CSA Group. 

1.7 When the term "anchor" is used throughout this Standard document it means the combination of the anchorage connector and the anchorage (structure). 

1.8 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. 

1.9 In this Standard, "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.
