Harnesses

Full-body harnesses

The body-support component of a personal fall-arrest system. Full-body harnesses certified to AS/NZS 1891.1 distribute arrest forces across the thighs, shoulders, chest, and pelvis — unlike superseded waist-only belts, which concentrated load on the lumbar spine and caused severe injury even in successful arrests. The right harness is a function of work type, D-ring configuration, and sizing.

Harness types

• Fall-arrest (single D-ring) — one dorsal (back) D-ring. The baseline harness for general fall-arrest where the user is working above an anchor.
• Fall-arrest + positioning (multi-D) — dorsal plus sternal (front) and/or side waist D-rings. Side D-rings allow work-positioning (leaning back in the harness to free both hands); sternal allows ladder climbing and rescue retrieval.
• Rope-access — specialised harness with low-profile side D-rings, built-in tool loops, and padded seat section for extended suspension work.
• Confined-space / rescue — additional rescue D-rings (usually shoulder-mounted) to allow vertical retrieval with the user kept upright.
• Tower climber — designed for repeated climbing, with seat padding and integrated positioning D-rings.

D-ring configuration guide

• Dorsal (back) — the only D-ring rated for fall arrest in most configurations. Positions the user head-up after an arrest.
• Sternal (front chest) — ladder climbing, ascender attachment, and rescue retrieval. Some sternal Ds are rated for fall-arrest on specific products — check the label.
• Side D-rings (waist) — work-positioning only. Not for fall-arrest — the arrest force would be transmitted through the lower back.
• Rescue D-rings (shoulders) — retrieval only, designed to be loaded simultaneously to keep the user vertical during extraction.

Sizing and fit

An incorrectly fitted harness will fail to distribute arrest forces properly. Check five points:

• Dorsal D-ring sits between the shoulder blades — not riding up or sliding down.
• Leg straps snug but allow a flat-hand to pass between strap and thigh.
• Chest strap sits mid-chest (not on the neck, not on the stomach).
• Shoulder straps sit flat with no twists.
• Waist straps (where fitted) sit on the hips, not the stomach.

Most harnesses are adjustable across S–XL or universal sizing; heavier-set and very tall users should look for XL or specific big-and-tall models.

Women's-fit harnesses

Several manufacturers now offer women's-specific harnesses with re-angled chest straps, shorter torso, and narrower shoulder spacing. If the standard-cut harness rides up into the neck or pinches, switch to a women's-fit model rather than tolerating a poor fit.

Pre-use inspection

Before every use, inspect:

• Webbing — no cuts, abrasion, chemical damage, heat burns, or UV fading that pulls colour out of the fibres.
• Stitching — no pulled, cut, or melted threads, especially around load-bearing points.
• Hardware — D-rings free of cracks, deformation, or corrosion; buckles function smoothly.
• Date of manufacture on the label — retire at 10 years regardless of condition.

Standards & compliance

All harnesses in this range are certified to AS/NZS 1891.1. Rescue-configuration harnesses are additionally certified to AS/NZS 1891.1 Appendix I (fall-arrest rescue). Six-monthly documented inspection by a competent person is mandatory under AS/NZS 1891.4.

Frequently asked questions

Can I attach my lanyard to the sternal D-ring for fall arrest?

Only if the harness's sternal D-ring is explicitly labelled for fall-arrest (marked with an "A" symbol or "fall arrest" text on the attachment point). Most general-purpose harnesses only rate the dorsal D-ring for fall-arrest. Sternal attachment during a fall can cause the user to flip and impact face-first.

How tight should leg straps be?

Snug enough that a flat hand passes between strap and thigh with mild resistance, but loose enough not to restrict circulation or movement. Leg straps left too loose can cause suspension trauma injury in a post-fall situation where the user hangs in the harness before rescue.

Do I need a harness for ladder climbing?

Under Australian codes, permanent vertical ladders above 6 m require a fall-arrest ladder-climb system (cable or rail), and the user needs a harness with sternal D-ring. For portable ladders and short fixed ladders, a harness may not be required but is advisable on tall ladders where a fall would exceed 2 m.
