The objective of this Standard is to provide users of fall-arrest systems and devices with requirements and recommendations relating to their selection, use and maintenance. (See also Clause 1 .6, which indicates where fall-arrest systems are placed within the hierarchy of control of fall protection).
The principles on which these requirements and recommendations are based, are summarized as follows:
(a) Any person at risk of a potentially injury producing fall shall be secured by equipment that is rated for fall arrest.
(b) A person suffering a fall when secured by a fall-arrest system shall-
(i) be subjected to an arresting force not exceeding 6 kN;
(ii) be wearing equipment that distributes fall-arrest forces over the body in a way that will minimize the possibility of injury;
(iii) be connected to a system which avoids the user reaching ground or striking any other obstacle that will cause injury, and maintains the user in a suitable post fall-arrest attitude for rescue purposes; and
(iv) be wearing a harness with at least a front fall-arrest rated attachment point,which may assist in rescue and which is designed to avoid or reduce the likelihood of suspension intolerance (trauma).
NOTE: This does not preclude the use of other permitted fall-arrest rated attachment points.
An assembly of interconnected components comprising a harness connected to an anchorage point or anchorage system either directly or by means of a lanyard or pole strap,and whose purpose is to arrest a fall in accordance with the principles and requirements of this Standard.
A fall or the arrest of a fall where the fall distance before the fall-arrest system begins to take any loading, is in excess of 600 mm either vertically or on a slope on which it is not possible to walk without the assistance of a handrail or hand line.AS NZS 1891.4 pdf free download.
