A fall-arrest harness is the last line of defence between a worker and a fatal fall. Unlike hard hats or boots, a harness failure is almost always catastrophic. That is why every harness must be inspected before each use by the wearer and undergo a formal periodic inspection by a competent person at defined intervals.
This guide covers the full pre-use inspection process, step by step. It applies to full-body harnesses used in construction, mining, telecommunications, wind energy and any other work at heights. The same principles apply to harnesses complying with AS/NZS 1891.1 (Australia) or OSHA 1926.502 (US).
Before you start
Find a clean, dry, well-lit workspace. Lay the harness out flat so all straps are visible and untangled. Have the manufacturer's inspection guide handy, along with an inspection checklist, an inspection tag and a pen. If the harness has been stored wet, muddy or in direct sunlight, pay extra attention to webbing condition.
Never inspect a harness while it is being worn. You need to see and feel every strap, buckle and connection point without restriction.
Step-by-step inspection
1. Check labels and identification
Locate the manufacturer's label. It must be legible and show the model number, serial number, date of manufacture and relevant standard (AS/NZS 1891.1 or EN 361). If the label is missing, illegible or the harness has no serial number, remove it from service immediately.
2. Inspect webbing on all straps
Work through every strap systematically: shoulder straps, chest strap, waist belt, leg straps and sub-pelvic strap. Flex each strap in an inverted "U" shape to open the fibres and check for:
- Cuts, nicks or frayed edges
- Chemical burns or discolouration
- UV degradation (fibres feel brittle or powdery)
- Heat damage (melted or glazed fibres)
- Pulled or broken stitching along the strap edges
3. Check stitching
Inspect all load-bearing stitch patterns (typically bar-tack or box-X patterns). Stitching must be intact with no loose, broken or pulled threads. Pay close attention to stitching at D-ring attachment tabs, buckle anchors and lanyard connection points, as these bear the highest loads in a fall.
4. Inspect D-rings and buckles
Check the dorsal D-ring (primary fall-arrest point), sternal D-ring and any side D-rings. They must be free of cracks, corrosion, distortion and sharp edges. Test each buckle for smooth operation. Tongue buckles should seat firmly; quick-connect buckles must click and lock. Any buckle that does not lock positively means the harness fails inspection.
5. Check lanyard and connectors
If a lanyard or self-retracting lifeline (SRL) is attached, inspect it as part of the same check. Look for frayed or cut webbing, damaged stitching on energy absorbers, and corrosion or gate-latch defects on snap hooks and karabiners. Connectors must open, close and lock smoothly.
6. Record and tag
Complete the inspection checklist with the date, inspector name, harness serial number and pass/fail result. Attach or update the inspection tag on the harness. If the harness fails any check, tag it as out of service and remove it from the work area.
Common defects and actions
| Defect | Action |
|---|---|
| Cut or frayed webbing | Remove from service, do not repair |
| Missing or illegible label | Remove from service, cannot verify compliance |
| Cracked or distorted D-ring | Remove from service immediately |
| Buckle does not lock | Remove from service, do not use |
| Harness involved in a fall arrest | Retire the harness, it must not be reused |
| UV-degraded or brittle webbing | Remove from service, retirement required |
Inspection frequency
Pre-use inspections by the wearer are required before every use. Formal periodic inspections by a competent person are required at intervals set by the manufacturer, typically every 6 or 12 months. Some jurisdictions and site safety management plans require more frequent formal inspections.
| Inspection type | Frequency | Who |
|---|---|---|
| Pre-use visual check | Before every use | The wearer |
| Formal periodic inspection | Every 6 or 12 months (per manufacturer) | Competent person |
| Post-incident inspection | After any fall arrest event | Competent person, then retire |
Regulatory requirements
In Australia, AS/NZS 1891.1 sets the design and testing standard for industrial fall-arrest harnesses. The WHS Regulations require a PCBU to ensure fall-arrest equipment is inspected by a competent person at intervals recommended by the manufacturer (WHS Reg r78). Harnesses involved in a fall arrest must be retired.
In the US, OSHA 29 CFR 1926.502 requires employers to provide personal fall-arrest systems that meet ANSI Z359.11 and to ensure equipment is inspected before each use. Damaged or fall-arrested equipment must be removed from service.
Going digital with MapTrack
Paper inspection tags fade, tear and get lost. With MapTrack, you can attach a QR code to each harness and scan it with your phone to launch the digital inspection form. The system records the serial number, inspector, timestamp and GPS location automatically, creating an auditable compliance trail.
When a harness is due for its periodic inspection or approaching its manufacturer-recommended retirement date, MapTrack triggers automated alerts so nothing is missed. All records are stored centrally for compliance reporting and regulator requests.
