Any harness equipment should be checked using a detailed inspection checklist, as outlined in AS/NZS 1891.4 ‘Industrial fall arrest systems and devices’ (see Appendix 3A for a checklist that you may use).
It is extremely important that all harnesses are checked before use. Consider that this is one of the most important pieces of equipment in catching you if you fall. Part of your inspection must include putting the harness on and checking that it fits correctly and is comfortable. Always follow the manufacturer’s instructions for fitting the harness.
