This edition has been prepared with the specific intention of aligning it with the recently published edition of AS/NZS 1891.1.

Principal changes from the previous edition are as follows:

(a) Removal of ‘total restraint’ from the scope of the Standard as equipment provided solely for restraint purposes is not dealt with in the AS/NZS 1891 series of Standards. This Standard recognizes only ‘restraint technique’ which allows for the possibility of a fall and requires the use of fall-arrest rated equipment and anchorages. For clarification purposes a description of ‘total restraint’ is given in Appendix F.
(b) Minimum allowable anchorage strength to be 12 kN or 15 kN depending on fall distance.
(c) New terminology for harnesses (full or lower body) and positioning of fall-arrest attachment points.
(d) Inclusion of twin-tail lanyards.
(e) In-service values for the extension of personal energy absorbers in fall situations.
(f) Lower body harness use restricted to limited free fall and restrained fall.
(g) Updated requirements for operator training and assessment.
(h) The term ‘suspension trauma’ has been changed to ‘suspension intolerance (trauma)’.
(i) A belt or waist strap alone in lieu of a harness is no longer permitted for any of the applications in this Standard to protect against a potential fall.

The term ‘informative’ has been used in this Standard to define the application of the appendix to which it applies.

An ‘informative’ appendix is only for information and guidance. Statements expressed in mandatory terms in footnotes to figures are deemed to be requirements of this Standard.
