ANSI/ASSE Z359: Fall Protection Standards System
The American National Standards Institute/American Society of Safety Engineers (ANSI/ASSE) Z359.1 - American National Standard Safety Requirements for Personal Fall Arrest Systems, Subsystems and Components standard was first published in 1992. For the first time, a voluntary consensus standard provided guidance for the manufacture of fall protection equipment and offered users a way to gauge how well a device would work. The standard also differentiated between positioning, restraint, and fall arrest; and defined active and passive fall protection. Following ANSI guidelines, it was reaffirmed in 1999, expanded in 2007 and revised in 2016.
Several new equipment/process-specific standards were developed within the Z359 series between 1997 and 2016. Some manufacturers chose not to follow these standards, but still claimed compliance with the most current version of Z359.1 (2007). At the time this was true because Z359.1-2007 did not specifically address the equipment/elements covered. The 2016 revision closed that loophole by referencing each of the existing 11 standards in the Z359 series.
ANSI/ASSE Z359.1-2016 - The Fall Protection Code received administrative approval on August 15, 2016 and is effective August 14, 2017. The primary intent of Z359.1-2016 is to provide a key to understanding and applying all of the various standards that make up the Z359 Fall Protection Standards System. It provides a single point of reference to define and validate compliance. With the publication of the 2016 revision, all of the requirements of the 2007 standard were superseded.
The Fall Protection Standards System is a series of existing and planned fall protection-related standards. These standards are designed to educate workers concerning proper use of equipment and overall safe work strategies and systems to minimize the distances and consequences of falls from heights should they occur.
As of this writing, the current Z359 Fall Protection Standards System includes:
- Z359.0-2012 – Definitions and Nomenclature Used for Fall Protection and Fall Arrest
- Provides terminology and definitions used through the code
- Z359.1-2016 – The Fall Protection Code
- Sets safety requirements for personal fall arrest systems, subsystems and components for connectors, full body harnesses, lanyards, energy absorbers, anchorage connectors, fall arresters, vertical lifelines and self-retracting lanyards
- Z359.2-2007 – Minimum Requirements for a Comprehensive Managed Fall Protection Program
- Establishes guidelines and requirements for developing and implementing a comprehensive managed fall protection program
- Z359.3-2007 – Safety Requirements for Positioning and Travel Restraint Systems
- Provides the minimum guidelines for the system design, manufacture and test of personal work positioning and travel restraint systems
- Z359.4-2013 – Safety Requirements for Assisted-Rescue and Self-Rescue Systems, Subsystems and Components
- Establishes requirements for performance, design, marking, qualification, instruction, training, use, maintenance and removal from service of equipment used in preplanned assisted-rescue and self-rescue for one or two workers
- Z359.6-2009 – Specifications and Design Requirements for Active Fall Protection Systems
- Specifies requirements for the design and performance of complete active fall-protection systems, including travel-restraint and vertical and horizontal fall-arrest systems and is intended for engineers with expertise in designing fall-protection systems
- Z359.7-2011 – Qualification and Verification Testing of Fall Protection Products
- Sets requirements for certification of ANSI Z359 Code products and components as well as requirements for third-party testing, witness testing and manufacturer self-certification of fall protection products and components
- Z359.11-2014 – Safety Requirements for Full Body Harnesses
- Establishes requirements for the performance, design, marking, qualification, instruction, training, test methods, inspection, use, maintenance and removal from service of full body harnesses used for fall arrest, positioning, restraint, suspension and/or rescue applications
- Z359.12-2009 – Connecting Components for Personal Fall Arrest System
- Sets requirements for the performance, design, marking, qualification, test methods and removal from service of connectors
- Z359.13-2013 – Personal Energy Absorbers and Energy Absorbing Lanyards
- Establishes requirements for the performance, design, marking, qualification, instructions, inspection, maintenance and removal from service of energy absorbing lanyards and personal energy absorbers
- Z359.14-2014 – Safety Requirements for Self-Retracting Devices For Personal Fall Arrest and Rescue Systems
- Sets requirements for performance, design, qualification testing, marking and instructions, inspection, maintenance and storage, and removal from service of self-retracting devices including self-retracting lanyards (SRL’s), self-retracting lanyards with integral rescue capability (SRL-R’s), and self-retracting lanyards with leading edge capability (SRL-LE’s), comprising personal fall arrest or rescue systems
- Z359.15-2014 – Safety Requirements for Single Anchor Lifelines and Fall Arresters for Personal Fall Arrest and Rescue Systems
- Sets requirements for the performance, design, marking, qualification, instruction, inspection, use, maintenance and removal from service of vertical lifelines
Planned ANSI/ASSE Z359 standards activity include:
- Z359.16 – “Safety Requirements for Climbing Ladder Fall Arrest Systems” received approval by the ASSE Board of Standards Review on November 2, 2016. Publication is expected in early 2017 with an effective date 180 days from publication.
- Sets requirements for the performance; design; marking; qualification testing; instructions for use; inspection; maintenance and storage; and removal from service of vertically oriented climbing ladder fall arrest systems
- Z359.18 – “Safety Requirements for Anchorage Connectors for Active Fall Protection Systems” is expected to receive approval during the first quarter of 2017.
- New standards - in development:
- Z359.9 – “Personal Equipment for Protection Against Falls – Descending Devises”
- Z359.17 – “Safety Requirements for Horizontal Lifelines for Personal Fall Arrest Systems”
The Z359 standards are constantly evolving and regularly revised. ANSI/ASSE Z359.1-2016 will be the guiding umbrella standard going forward and will be kept up to date as other Z359 standards are revised, developed and published. Products must meet the requirements of the current version of the applicable standard when purchased. Products in use when revisions or new standards become effective may continue to be used until they are removed from service.
The ANSI/ASSE Z359 Fall Protection Standards System provides the requirements to help minimize serious injuries often caused by misuse, poor product selection, inadequate training or possibly damaged/worn fall protection equipment. This document provides a basic understanding of the standards and the key changes that have either been incorporated or are in development. It is intended to provide an overview of the standards only. It is not an exhaustive, all inclusive, account of every change in all of the included or planned standards.
