HOW TO PROPERLY INSPECT A SAFETY HARNESS BEFORE USE

A safety harness is often the last line of defence between a worker and a fatal fall. While most users understand the importance of wearing fall protection equipment, far fewer treat pre-use harness inspection with the seriousness it demands. Many fall-related injuries and deaths occur not because a harness was missing, but because it was damaged, worn, or improperly maintained - and those defects went unnoticed.

Inspecting a safety harness before each use is not optional. It is a critical safety requirement designed to identify failures before they become catastrophic. This article explains how to properly inspect a safety harness, what to look for, and what to do if damage is found - using real-world examples of what happens when inspections are rushed or ignored.

Why Pre-Use Safety Harness Inspection Matters

Falls from height remain one of the leading causes of serious injury and death in construction, maintenance, roofing, tower work, and industrial settings. In many post-incident investigations, the harness involved showed visible damage that should have been caught during a routine inspection.

In one documented case, a maintenance worker fell from a mezzanine platform while wearing a harness that appeared intact at a glance. After the incident, investigators found severe internal webbing abrasion hidden beneath surface fibres. The damage had developed over time from chemical exposure and sharp edges. A basic hands-on inspection would have revealed stiffness and thinning in the webbing - but it was never performed.

A proper inspection takes only a few minutes. The cost of skipping it can be permanent.

Webbing and Stitching Inspection

The webbing is the structural backbone of a safety harness. If it fails, the entire system fails.

How to Inspect Harness Webbing

Begin by holding the harness in good lighting. Slowly run your hands along every length of webbing, bending it slightly to expose hidden damage. Do not rely on visual inspection alone - many defects are only detectable by touch.

Look and feel for:

• Cuts, nicks, or tears
• Fraying or broken fibers
• Abrasion or thinning
• Burn marks, welding spatter, or heat damage
• Discoloration from chemical exposure
• Hardening, brittleness, or excessive stiffness

Pay close attention to high-stress areas such as:

• Shoulder straps
• Leg straps
• Lanyard attachment points
• Areas around D-rings and buckles

Stitching Checks

Stitching holds load-bearing sections together. Even minor stitching damage can compromise harness strength.

Inspect all stitched areas for:

• Broken, loose, or pulled stitches
• Missing bar tacks
• Uneven or frayed thread
• Signs of chemical degradation

Real-world failure example:
A roofer fell when the back D-ring tore free from the harness. The webbing itself was intact, but the stitching securing the D-ring had deteriorated due to prolonged UV exposure. The worker had worn the harness daily but never inspected the stitching closely. The damage was visible - but only if someone bothered to look.

If webbing or stitching shows any sign of damage, the harness must be removed from service.

Buckles, D-Rings, and Hardware Checks

Metal components may look durable, but they are not immune to failure. Hardware defects are common in older or heavily used harnesses.

Buckles

Check all buckles (tongue, quick-connect, friction, or pass-through) for:

• Cracks or deformation
• Corrosion or rust
• Sharp edges or burrs
• Proper movement and locking function

Fasten and unfasten each buckle to confirm it engages smoothly and securely. Buckles that stick, bind, or fail to lock correctly should not be trusted at height.

D-Rings and Attachment Points

Inspect D-rings carefully:

• Ensure they are not bent, cracked, or excessively worn
• Check for corrosion, pitting, or sharp edges
• Confirm they rotate freely (if designed to do so)

Pay close attention to how D-rings are seated in the webbing. Excessive movement or distortion can indicate internal damage.

Real-world failure example:
A tower technician survived a fall but suffered severe injuries when a corroded D-ring fractured under load. The corrosion was clearly visible but dismissed as “surface rust.” The harness had been stored in a damp environment for months. A simple hardware check would have prevented the incident.

Labels and Certification Tags

Labels are not just informational - they are a critical safety component.

What to Check on Harness Labels

Every safety harness should have legible labels indicating:

• Manufacturer name
• Model number
• Date of manufacture
• Applicable safety standards (OSHA, ANSI, CSA, EN, etc.)
• Inspection and use instructions

If labels are missing, illegible, or removed, the harness should be taken out of service. Without labels, you cannot verify compliance, service life, or proper usage.

Many manufacturers specify a maximum service life, regardless of appearance. Using a harness beyond its recommended lifespan increases the risk of hidden material degradation.

Real-world failure example:
In an industrial facility, a worker used a harness that had been in circulation for over 12 years. The labels had worn off long ago, and no one knew its age. The harness failed during a slip event- not from a full fall, but from shock loading. Investigation revealed the webbing fibres had degraded well beyond their service life.

What to Do If Damage Is Found

If any defect is discovered during inspection, do not attempt to repair the harness unless explicitly permitted by the manufacturer. Most personal fall protection equipment is not field-repairable.

Proper Steps When Damage Is Identified

1. Immediately remove the harness from service
2. Tag it clearly as “DO NOT USE”
3. Report the issue to a supervisor or safety manager
4. Replace the harness or follow manufacturer inspection and replacement procedures

Never make assumptions that damage is “minor” or “cosmetic.” Harnesses are engineered systems. Any compromise can significantly reduce their ability to arrest a fall safely.

Post-Fall Rule

Any safety harness involved in a fall or shock-loading event must be removed from service immediately - even if no damage is visible. Internal fibres may be damaged beyond detection.

Common Inspection Mistakes to Avoid

Even experienced workers make inspection errors that undermine safety.

These include:

• Rushing inspections at the start of a shift
• Only checking visible areas
• Ignoring stiffness or texture changes
• Assuming shared equipment was already inspected
• Continuing to use “almost new” harnesses without checking

In many serious incidents, the worker believed the harness was safe simply because it “looked fine.” Proper inspection requires time, attention, and consistency.

Final Thoughts: Inspection Is a Life-Saving Habit

Inspecting a safety harness before each use is not paperwork, and it is not a formality. It is a proven method of preventing injuries and fatalities. Every cut, frayed stitch, corroded buckle, or missing label tells a story - often one that ends badly when ignored.

A few minutes of inspection can mean the difference between a routine workday and a life-altering fall. When it comes to fall protection, assumptions kill and inspections save lives.

If a harness raises even a small doubt during inspection, trust that instinct. Remove it from service. Replace it. Lives depend on it.
