Fall Protection Equipment Inspection: What to Check Before Every Use

Manufacturers publish detailed inspection criteria for harnesses, lanyards, and SRLs, but the gap between what's on that sheet and what actually happens before a worker clips in each morning is where most equipment failures trace back to. A pre-use inspection isn't a formality to check off; it's the single point in the day where a piece of gear that's been quietly degrading, from UV exposure, chemical contact, an unreported near-miss, or just accumulated wear, gets caught before it matters.

Webbing and Rope: What Damage Actually Looks Like

Webbing on a harness or lanyard should be checked by running it slowly through your hands, looking and feeling for cuts, abrasion that's worn through the outer fibers, burns, or chemical damage that shows up as stiffness, discoloration, or a glossy, melted appearance where the fibers have been exposed to heat or acid. Fraying at stitch lines or bar tacks, the small reinforced stitching points that hold webbing to hardware, is a specific failure point worth checking separately from general wear along the strap length, since these points carry concentrated load during an arrest. Any webbing that's stiff, brittle, or has lost its normal flexibility should be treated as suspect even without visible cuts, since UV degradation weakens synthetic fiber well before it becomes visually obvious.

Hardware: D-Rings, Buckles, and Connectors

Metal hardware should be checked for cracks, sharp burrs, deformation, and corrosion, with particular attention to D-rings since they carry the full arrest load and a bent or twisted D-ring changes how force transfers through the harness during a fall. Buckles need to close and lock fully, and any buckle that doesn't seat with a positive click or that can be pulled open without deliberately releasing it should pull the harness from service immediately rather than getting a pass because the rest of the unit looks fine. Snap hooks and carabiners on lanyards need their gate mechanism checked for proper spring action and self-locking function; a gate that doesn't close fully or a locking sleeve that doesn't engage defeats the connector regardless of how strong the hook body itself is rated.

Stitching and Labels

Stitching should show no cut, pulled, or abraded threads, and broken stitches at load-bearing points are a retire-the-item finding even if the surrounding webbing looks undamaged, since stitching failure at a bar tack can let webbing pull free of hardware under load. The manufacturer's label with model number, serial number if applicable, and inspection date fields should still be legible; a harness with an unreadable or missing label can't be matched against manufacturer recall information or service history, which on its own is reason enough to flag it for closer review even if no physical damage is visible.

SRLs and Impact Indicators

Self-retracting lifelines need the line to pay out and retract smoothly across its full length without hesitation, sticking, or slack that doesn't retract fully, any of which can indicate an internal spring or braking mechanism problem that isn't visible from outside the housing. Many SRLs and shock-absorbing lanyards include a visual impact indicator, a tear-away flap, colored panel, or exposed stitching that deploys or changes appearance once the unit has arrested a fall, and any unit showing a deployed indicator has to be removed from service regardless of how it otherwise looks, since it's already done its job once and isn't rated for a second event.

What Actually Happens When Something Fails

The inspection only works if there's a real consequence attached to a failed item, meaning it gets tagged out and physically removed from the equipment pool that day, not set aside with a mental note to deal with it later. A harness or lanyard that fails inspection and gets used anyway because it's the only one available defeats the entire purpose of doing the check, and building in enough spare inventory that a failed item can be swapped without delaying work is part of what makes a pre-use inspection program function in practice rather than in theory. Documentation matters too; a simple log of what failed and when helps identify whether a particular batch, storage condition, or usage pattern is causing premature wear across multiple units.

These checks apply on top of proper harness fit and D-ring positioning covered in our fall protection harness guide, since a harness can pass every inspection point and still fail to protect a worker if it isn't adjusted correctly for their body and the task.

ANSI Z359.2 outlines managed fall protection program requirements including inspection frequency and documentation, and OSHA requires equipment inspection before each use under its fall protection standards (osha.gov).
