TECHNICAL GUIDE & PRODUCT USER MANUAL
RISK ASSESSMENT PROCEDURES
Risk assessments should be conducted prior to any Work at Height or Confined Space Work being carried out to identify hazards that exist and the risks they pose.
AS/NZS 1891.4:2009 contains a Hierarchy of Control which provides an ideal platform for development of risk assessments. Below is a sample Risk Assessment Procedure for working at height.
HAZARD
ASSES
ACTION
Falling from a height
Elimination
No risk
Slipping or tripping on a roof surface
Limited risk
Substitution
Fall restraint technique
Isolation
Fall arrest
Safe work systems
Fall protection
Consequences of a fall
Recovery systems
Reference to local authorities is also recommended. This table is a sample only as many other hazard factors can come into account. Other hazards may include, but are not limited to: Nature of the work, surface materials, fragile roofing material, personal training levels, competency, weather conditions, surface conditions, etc. Reference should be made to AS/NZS 1891.4:2009 for the Correct Use, Selection and Maintenance criteria for Height Safety Systems.
It is recommended that wherever possible a “Restraint Technique” System is used. This is a system where a person using fall arrest rated equipment, is prevented from reaching a position from where a fall is possible.
Relevant Australian/New Zealand Standards listed below are recommended for further reading: AS/NZS 1891.1:2007 Industrial Fall-Arrest Systems And Devices – Harnesses And Ancillary Equipment. This is a manufacturing standard which specifies requirements for materials, design, manufacturing and testing of harnesses, lanyards, pole straps and associated equipment. Testing utilises 100kg mass – users of greater mass should consult manufacturer. AS/NZS 1891.2:2001 Industrial Fall-Arrest Systems And Devices – Horizontal Lifeline And Rail Systems. AS/NZS 1891.3:1997 Industrial Fall-Arrest Systems And Devices – Fall Arrest Devices. AS/NZS 1891.4:2009 Industrial Fall-Arrest Systems And Devices – Selection, Use And Maintenance. This is a user orientated document outlining selection criteria, safe use, inspection and maintenance requirements of products and systems used in fall protection.
These Standards are to be used as a guide to form safe work procedures, however, they are not all inclusive.
