Climbing Lanyard Inspection: 7 Checks from a PPE Quality Inspector

I'm a quality and brand compliance manager at a PPE company. I review every climbing lanyard and harness before it reaches customers—roughly 300 items per week. I've rejected about 12% of first deliveries in 2025. Common reasons: inconsistent stitching, mislabeled connectors, and energy absorbers that didn't pass pull-test verification.

This checklist is for safety managers, small team leads, and anyone buying climbing lanyards—Petzl or any other certified manufacturer—who wants to know what actually matters when inspecting gear. Seven checks, in the order I run them, plus the mistakes that show up most often. It's the same process I use for incoming batches and pre-use inspections.

When to use this checklist

Use it when you receive new equipment, when you're evaluating a new supplier, or for the routine pre-use check that should happen on every shift. One thing up front: this doesn't replace the manufacturer's manual. It works alongside it. If you're ever unsure whether a piece of gear passes, the answer is no. Tag it out and pull it from rotation.

Step 1: Read the label like a contract

The certification label isn't a decal. What I mean is: it's a legal document stating what this device is rated for, which standards it meets, and what it's designed to do. For lanyards, look for EN 354 for lanyards, EN 355 for energy absorbers, and in the US, compliance with OSHA 29 CFR 1910.140 for personal fall arrest systems.

Per FTC guidelines (ftc.gov), a claim like "fall-arrest-rated" has to be substantiated. If a lanyard doesn't have a cert mark and a traceable standard number, treat the claim as suspect. I've seen knockoff lanyards with "CE" printed on them that fell apart during the first inspection. The label is the first line of defense.

Step 2: Run the webbing through your fingers

Do this before you look at it. Close your eyes and feel the full length of the webbing. Damage hides in the middle of the strand, not at the ends. You're feeling for:

• Fraying or fuzzy patches that indicate abrasion
• Glazing—stiff, shiny spots from heat or friction
• Hard or brittle sections from chemical exposure
• Sudden soft areas that might mean core damage

When I inspect a climbing lanyard Petzl sends through our warehouse, the webbing has consistent flexibility along its length. If that consistency is off, something has aged or damaged the material. You don't need a materials engineering degree to catch this. You need hands-on habits.

Step 3: Inspect the stitching where it matters

Not all stitching on a lanyard is load-bearing. The bartack stitches near the termination points—where the webbing loops around the connector—carry the load. The edge stitches are mostly for stability.

Check for pulled threads, abrasion, and cut stitches on the load-bearing bartacks. A single cut thread across a load-bearing bartack is an automatic fail. I don't care if the rest of the lanyard looks new. That's the one spot I won't compromise on.

I'm not a materials engineer, so I can't tell you exactly how much strength a cut bartack loses. What I can tell you from a quality perspective is that we reject entire batches when we see it—because if one stitch is compromised, the others in the same run usually are too.

Step 4: Test the connectors

Carabiners should snap cleanly. That's the first thing I check—gate action. A gritty gate means the spring is failing or the mechanism is full of fine sand. Both are reasons to retire the connector.

Look at the gate face for scoring or rust. Test the locking function properly—not just whether it spins, but whether it locks. The worst mistake on connectors is treating a worn locking action as a "minor issue." The lock is what keeps the connector attached under load.

On Petzl lanyards, the connectors are usually marked with the strength rating on the spine. If that marking is worn off, it's a red flag. A connector with an unreadable rating doesn't belong on a jobsite.

Step 5: Check the energy absorber

If your lanyard has an energy absorber—the shock pack near the attachment end—that's where a lot of the fall protection happens. The lanyard is designed to keep you connected. The absorber limits the force your body feels during a fall.

Check the protective cover for tears or burns. Look at the tear stitching: the heavy threads meant to progressively rip open during a fall. If those are cut, broken, or missing, the absorber won't function as designed.

I see more people kill their energy absorbers by dragging them over sharp steel edges than by falling on them. The cover gets sliced, nobody notices, and the rest of the lanyard looks fine. The surprise isn't that damaged gear fails later. It's how often people tell me "it looks okay" without ever having opened the cover to check.

Step 6: Verify compatibility with your harness

Not every lanyard connects cleanly to every harness. This is where product lines matter. If you have a Petzl Volt Wind harness—I've seen these used a lot for wind turbine and work-at-height operations—you want a lanyard that actually matches its attachment points.

Checking compatibility is simple: connect the lanyard the way it's meant to be used. Does the connector seat fully on the harness attachment point? Does it rotate without binding? Can you operate the lock while wearing gloves? If you have to force it, it's the wrong combination.

To be fair, most lanyards and harnesses within the same brand work together. The problems show up when you mix brands or use an adapter you don't fully understand. If you're pairing a climbing lanyard Petzl makes with a Petzl harness, you're usually fine. But "usually" isn't a safety standard—check the compatibility chart anyway.

Step 7: Document the inspection

Date, inspector, result. Write it down or log it. Every lanyard has a serial number—use it. Attach an inspection tag when you buy the gear, and record every inspection after that. Documentation is the step most teams skip.

I only believed in logging every inspection after skipping it once and paying for it. A customer asked for the inspection history on a batch we'd supplied. I couldn't produce it because we hadn't recorded item-level checks. That cost us a $22,000 redo and delayed our launch. Now every contract includes serial-level traceability.

If you're a small team, the paperwork feels like overkill. I get it—with six lanyards instead of six hundred, you know each one by sight. But documentation is the difference between claiming "we tested it" and being able to prove it.

When I was starting out, the vendors who took my small orders seriously are the ones I still use for large contracts. Small doesn't mean unimportant—it means potential.

Quick checks for the rest of your PPE

Lanyards get most of the attention, but the rest of the kit deserves the same standard. Here's what I look at during a full team audit:

Safety vests

A safety vest isn't a fashion choice. Check that the reflective tape hasn't delaminated or lost its retroreflectivity. In the US, a compliant vest meets ANSI/ISEA 107—the standard is on the label. If the label has faded and you can't read the standard, replace the vest.

The surprise wasn't the price difference between a $12 vest and a $35 vest we tested. It was how differently they looked under truck headlights after one season of washing. The cheap one was practically invisible. Upgrading specs cost more up front, but the crew stopped going through vests every few weeks, so it evened out.

Work boots

I'm not a footwear specialist, so I can't speak to the biomechanics of ankle support. What I can tell you from a quality perspective is that boots—including the Hoka work boots I've seen on some crews lately—are safety equipment, and they should be inspected like it. Check the soles for delamination, the toe cap for exposed composite, and the laces for fraying. I want to say the toe impact standard is ASTM F2413-18, but I might be misremembering the exact update year.

The common mistake is replacing boots only when they're visibly falling apart. By that point, sole adhesion and the moisture barrier have often been compromised for weeks. If the boot leaks, it's not doing its job.

Leather gloves

If you're searching for how to soften leather gloves, the short answer is: use a leather conditioner or saddle soap, work it in with your hands, and let them dry naturally. Don't bake them. Heat destroys the leather's structure and makes things worse.

From a quality perspective, I check gloves for seam integrity, cracks between the fingers, and holes. A glove with a torn seam offers roughly the same protection as no glove at all, but people wear it anyway because "it's still mostly fine."

Notes: When to retire gear

The rules are simple:

• After any fall or major shock load, retire the lanyard and energy absorber immediately. Even if it looks fine—the internal structure can be compromised without visible signs.
• Visible damage—cut webbing, cut stitching, cracked connector—means retirement.
• If the inspection history is lost, treat the gear as un-inspected.
• If you're not sure, pull it from rotation.

Some teams run the "cost per use" math on whether to keep or retire gear. I get why budgets matter. But the math changes when the consequence is a fall injury. Retiring a $150 lanyard early is cheaper than the alternative, every time.

Final thought

There's something satisfying about a well-run inspection process. After the initial resistance and the paperwork grind, when you can look at a rack of gear and know exactly what's in service, what's been checked, and what's due next—that's the payoff.

Logo loyalty matters less than people think. We use a lot of Petzl equipment, and it's solid. So is other certified gear from reputable manufacturers. What separates a safe team from an unsafe one isn't the label on the gear. It's the habit of checking, documenting, and retiring equipment when it needs to be retired.
