How To Carry Out Safety Harness Inspection and Precautions

To carry out a safety harness inspection, begin with a pre-use visual and tactile inspection, checking the legibility of tags, integrity of webbing, stitching, and hardware, and immediately remove any harness that shows damage, wear, or has been involved in a fall. Then, perform frequent (daily) inspections before each use and schedule formal periodic inspections (by a competent person) at least every 6–12 months—documenting and tagging outcomes accordingly.

Why is Safety Harness Inspection Crucial?

Ensuring harness safety is not just best practice—it’s legally required and literally life-saving. OSHA mandates that personal fall protection systems (which include safety harnesses) must be inspected before initial use each workshift for signs of mildew, wear, or damage, with defective components removed from service immediately. Furthermore, harnesses must receive a formal inspection at least annually by a competent person; more frequent reviews may be needed depending on manufacturer recommendations or use conditions.

Proper inspection ensures regulatory compliance (e.g., OSHA 1910.140, ANSI Z359 standards) and, more importantly, ensures that when a fall occurs, the harness will perform and protect the wearer.

What is a Pre-Use Safety Harness Inspection, and How do I Perform it?

A pre-use inspection is what you conduct before each workshift, before donning the harness. Here’s how to carry it out conversationally and practically:

Start with the ID tag or label. Make sure the manufacturer name, model number, serial number, date of manufacture, and inspection records are clear and legible. Without a readable tag, you can’t trace materials or verify service life—so unreadable tags are an immediate fail.

Next, go hand-over-hand through hardware components: D-rings, buckles, grommets, adjusters—feel and visually check for distortion, corrosion, cracks, bends, or sharp edges. Test tongue buckles—ensure the tongue overlaps the frame, moves freely, and the roller turns freely.

Then, inspect the webbing. Use the bend or inverted U technique on each 6–8 inch segment to expose surface flaws: cuts, abrasions, fraying, broken fibers, chemical or UV damage, heat burns, melting, discoloration, mildew, or hard/spotted areas. Be especially alert for telltale or load indicator areas that show red or unusual color when compromised.

Inspect stitching and sewn terminations—they must be intact. Look for pulled, missing, or cut stitches, particularly around load-bearing connections.

If any defects are found—or the harness has arrested a fall—remove it from service immediately.

In short: Tag only if legible; hardware intact; webbing flawless; stitching solid. If any fail, don’t use it.

This friendly, user-centric explanation ensures that anyone (from a construction worker to a safety officer) can understand how to do a pre-use check confidently.

What is a Formal Periodic Harness Inspection, and what should it include?

A formal periodic inspection goes beyond daily pre-use checks. Conducted at least every 6 to 12 months (often annually), it must be done by a Competent Person and thoroughly documented.

Here’s what that means:

• Performed by someone designated and trained—OSHA defines a Competent Person as one capable of identifying hazards and authorized to correct them.

• Inspection includes: all elements from pre-use inspection plus tag/tagging checks, reviewing service life, documentation of findings, and ensuring all markings and labels remain legible.

• Documentation typically captures:

This aligns with OSHA/ANSI guidelines and is critical for audits and safety record-keeping.

Also, if a harness is involved in a fall arrest, even mid-shift, it must be immediately pulled from service and evaluated formally—even if there are no visible defects.

Who Performs What Inspections—Initial, Frequent, and Periodic?

Initial inspection: When a harness is new or first received, the authorized person or user should ensure it’s the correct model/size, has no defects in stitching or webbing, and that labels/tags are intact.

Frequent inspection: Before every use (daily pre-use), the user (authorized person) should do the tactile and visual check described earlier. If harnesses are shared, inspect again after use, too.

Periodic inspection: Conducted by a Competent Person (often a third party or safety officer), documented, usually every 6–12 months, depending on usage and environmental exposure.

When Should a Harness be Retired?

You must remove a harness from service if any of the following apply:

• Visible damage—cuts, fraying, abrasions, broken fibers, hard or shiny (heat) spots, chemical or UV damage, mold/mildew, discoloration.

• Hardware defects—bending, cracking, corrosion, distortion of D-rings, buckles, grommets, and sharp edges.

• Stitching problems—pulled, missing, or damaged stitches, insecure sewn terminations.

• Failed load indicator or fall-indicator showing (e.g., load-fold indicators frayed).

• Involved in a fall arrest or impact-loading event.

• Expired Service Life—manufacturer’s recommended service life exceeded (often 5 years).

• Missing or illegible tags/labels render traceability and inspection history invalid.

Any doubt—as some safety professionals say:

“When in doubt, check manufacturer resources… they have pictures of what you should fail and what you can keep using.”

Step-by-Step Safety Body Harness Inspection Guide

1. Before you start (Setup in under 2 minutes)

• Lighting & surface: Work in bright, even light on a clean table.

• Clean hands/PPE: Use clean, dry hands or light gloves so you can feel defects.

• Tools (optional but helpful): Small flashlight, ruler (for measuring cuts/abrasions), magnifier, non-permanent marker, inspection tags, and your inspection log.

Step 1 — Isolate and identify the harness

• Lay out one harness at a time to avoid mixing components.

• Read the label/tag: Confirm manufacturer, model, serial number, and date/ID are legible. If the tag is missing or unreadable, remove it from service immediately.

Step 2 — Check fall/impact history

• Ask the user or review records: Has this harness been involved in a fall-arrest or severe impact?

• If yes or uncertain, remove from service pending competent evaluation or disposal.

Step 3 — Start with the back D-ring assembly

• Inspect the dorsal D-ring for bends, cracks, distortion, corrosion, burrs, sharp edges, or weld defects.

• Rotate the D-ring—movement should be smooth with no binding; the back plate should be secure.

Step 4 — Inspect all hardware (Top to bottom)

• Chest, side, and front D-rings (if present), buckles, adjusters, grommets, and keepers.

• Check for deformation, hairline cracks, corrosion, sharp edges, missing rollers, seized mechanisms, or misaligned tongues.

• Ensure buckles engage positively and release properly.

Step 5 — Do the “bend test” on webbing

• Working strap by strap, bend the webbing into a tight U every 6–8 inches.

• Look and feel for cuts, nicks, frayed fibers, fuzzing, glazing/melting, hard/stiff spots (heat/chemical damage), soft/spongy spots (chemical/UV), discoloration, or embedded grit/metal filings.

Step 6 — Inspect load-bearing stitching

• Focus on stitched terminations, web-to-hardware joints, and sub-pelvic/seat areas.

• Look for broken, pulled, loose, or missing stitches; uneven thread tension; frayed bar-tacks.

• Lightly run a fingernail over stitch lines—snags or step-offs can signal broken threads.

Step 7 — Check shoulder, chest, leg, and sub-pelvic straps

• Confirm strap continuity (no splices or unauthorized alterations).

• Verify strap routing is correct through buckles/adjusters and that keepers are present and secure.

• Look for edge wear where straps pass hardware or rub points.

Step 8 — Examine pads and comfort liners

• Remove or open pads if possible; check the under-webbing beneath pads.

• Pads should be free of cracks, delamination, hardening, contamination, or trapped debris that could abrade the webbing.

Step 9 — Inspect webbing terminations and ends

• Strap ends should be heat-sealed (if applicable) and not unravel.

• No tape, knots, or makeshift repairs—these are grounds for immediate removal.

Step 10 — Look for chemical, paint, and heat damage

• Shiny/glazed fibers = heat. Brittle/hard sections = chemical or heat. Bleached/faded areas can indicate UV degradation.

• If you smell solvents or see heavy contamination (oil, resin, concrete, battery acid), remove from service and follow manufacturer guidance.

Step 11 — Verify fall/load indicators

• Many harnesses include fall or load indicators (e.g., revealing a contrasting tab or stitched tear-web).

• If an indicator is triggered, partially deployed, or missing, remove it from service.

Step 12 — Operate every buckle and adjuster

• Tighten/loosen through full travel; ensure teeth bite properly, tongues seat in grommets without elongating holes, and friction adjusters hold without slipping.

Step 13 — Check connectors and integration points

• If permanently attached components are present (suspension trauma straps, belts, integrated lanyards), inspect them as rigorously: Webbing, stitching, hardware, deployment indicators.

Step 14 — Confirm labeling and instructions

• The instruction booklet or QR/manual reference should be accessible.

• If labels/instructions are illegible or missing, you can’t verify limits and use—remove from service.

Step 15 — Fit-check (optional but recommended)

• Put the harness on a mannequin or have the user don it under supervision.

• Confirm D-ring sits between shoulder blades, leg and chest straps adjust to snug without pinch, and nothing slips during movement.

• Any fit issues due to stretched or slipping adjusters can indicate hidden wear.

Step 16 — Make the pass/fail decision

• Pass only if all webbing, stitching, hardware, labels, and indicators are sound.

• Fail if any defect is found—or if you’re in doubt.

Step 17 — Document the inspection

• Record date, inspector name/signature, asset ID/serial, condition notes, pass/fail decision, next due date.

• Attach a status tag (e.g., green = pass, red = out of service). Keep records where supervisors can easily verify.

Step 18 — Clean, store, and schedule next inspection

• If it passes, clean per manufacturer instructions (mild soap, no solvents), then dry fully.

• Store in a cool, dry, dark cabinet or bag—away from sunlight, chemicals, sharp edges, or heat sources.

• Schedule the next pre-use checks (every use) and periodic inspections by a competent person (commonly every 6–12 months or per manufacturer).

Pro tips

• Train fingertips: Your fingers often “feel” broken fibers or heat damage before your eyes catch it.

• De-grit regularly: Fine dust and metal swarf act like sandpaper—wipe and brush harnesses after dusty work.

• Control storage: UV and heat are silent killers. A closed cabinet extends life dramatically.

• Separate paint/chemical tasks: Issue sacrificial harness covers or designated harnesses for dirty trades to protect primary webbing.

• Photograph defects: Add photos to your log—great for training and audit trails.

• Standardize tags: Color-coded pass/out-of-service tags reduce “accidental” use of failed gear.

How should you store and maintain a harness to extend its life?

Good storage and maintenance are vital for harness longevity:

• Keep harnesses clean—grime can hide defects or damage material; clean per manufacturer instructions.

• Store in cool, dry, shaded areas, away from direct sunlight, heat, chemicals, oil, or solvents that degrade nylon/polyester webbing.

• Avoid sharp edges—don’t hang harnesses on protruding nails or hooks.

• Tag harnesses clearly with inspection dates and keep inspection records accessible.

• Follow the manufacturer’s guidelines for cleaning, drying, and storage to maintain certification.

Frequently Asked Questions

How often should I inspect a body harness?

• Every use (pre-use check) by the wearer, plus a periodic inspection by a competent person on a set schedule (commonly every 6–12 months, or as the manufacturer specifies and your risk assessment dictates).

Can I keep using a harness after a fall if it “looks fine”?

• No. Treat it as out of service pending competent evaluation or disposal unless the manufacturer provides a certified inspection/recertification program (rare for harnesses).

Do harnesses have an expiry date?

• Manufacturers set service-life guidance based on use and conditions. Don’t rely on age alone—condition + manufacturer instruction govern fitness for use.
