AS 1891.1 – 2007 Industrial Fall Arrest Systems and Devices

Part 1: Harness and Ancillary Equipment

AS 1891.1 – 2007 Industrial Fall Arrest Systems and Devices – Part 1: Harness and Ancillary Equipment specifies requirements for the materials, design, manufacture and testing of harnesses, lanyards, pole straps and associated equipment including connecting devices and personal energy absorbers for industrial restraint and fall-arrest purposes .Appendices include test methods for equipment items and assemblies, and for component materials.

PREFACE

This Standard was prepared by the Joint Australian/New Zealand Committee SF-015, Industrial Safety Belts and Harnesses to supersede AS/NZS 1891.1:1995, Industrial fallarrest systems and devices, Part 1: Safety belts and harnesses. It is the first in a series of Standards dealing with this area of industrial safety, the full series being as follows:

This Standard incorporates Amendment No. 1 (October 2007) and Amendment No.2 (May 2008). The changes required by the Amendments are indicated in the text by a marginal bar and amendment number against the clause, note, table, figure or part thereof affected.

FOREWORD

The ability of the human body to survive a fall with the minimum chance of serious injury will depend principally on the decelerating forces imposed on the body during fall-arrest and the manner in which those forces are transmitted to the body. These factors have been recognized in the preparation of this Standard in two ways.

Firstly, equipment used to arrest a free-fall, i.e., an unrestrained fall either vertical or down a steep slope, is required to be designed so that forces developed in the supporting lanyard during the fall do not exceed 6 kN, i.e. the deceleration is limited to 6g. Secondly, this level of deceleration is readily survivable provided the person suffering the fall is properly constrained in a harness. There is ample evidence to show that even for relatively short restrained or unrestrained falls, the wearing of a belt only can lead to injuries such as broken ribs, or damage to the kidneys, spleen or lungs. For this reason this Standard envisages that, as a minimum, a person at risk of any fall will wear a harness. Attention is also drawn to the problem of suspension trauma, the adverse consequences which can arise if a person remains suspended in a harness for any length of time.

AS/NZS 1891.4 gives a more detailed account of suspension trauma together with other requirements and recommendations related to the selection, safe use and maintenance of harnesses, lanyards and other fall-arrest equipment and systems, and should be read in conjunction with manufacturers’ instructions…
