OSHA requires a safety harness to be inspected before its initial use during each workshift, and again by a competent person any time the harness has been subjected to fall-arrest forces. Those are the only two inspection frequencies written into the federal regulations. The widely repeated idea that OSHA also mandates an annual inspection comes from ANSI voluntary consensus standards, not from OSHA itself.
The Pre-Shift Inspection Every Worker Owes
Both the general industry and construction standards require a pre-use check. In general industry, 29 CFR 1910.140(c)(18) states that personal fall protection systems “must be inspected before initial use during each workshift for mildew, wear, damage, and other deterioration, and defective components must be removed from service.”1Occupational Safety and Health Administration. 1910.140 – Personal Fall Protection Systems The construction rule, 29 CFR 1926.502(d)(21), phrases it slightly differently but reaches the same result: harnesses “shall be inspected prior to each use for wear, damage and other deterioration.”2eCFR. 29 CFR 1926.502
This is the worker’s own inspection, done every day before putting the harness on. OSHA has confirmed in a letter of interpretation that this pre-use check does not need to be performed by a “competent person.” The worker wearing the equipment handles it.3Occupational Safety and Health Administration. Standard Interpretations – Personal Fall Arrest Systems Inspection It should be visual and hands-on: look at the webbing, run it through your hands feeling for damage, check the hardware, and confirm everything operates properly. A few minutes at most. Skipping it is a citable violation.
Inspection After a Fall Arrest
The second inspection frequency in OSHA’s rules is not on a calendar. It is triggered by an event. Under 29 CFR 1926.502(d)(19), when a personal fall arrest system has been subjected to impact loading, the equipment must be “immediately removed from service and shall not be used again for employee protection until inspected and determined by a competent person to be undamaged and suitable for reuse.”2eCFR. 29 CFR 1926.502 The general industry standard at 1910.140(c)(17) contains an identical requirement.1Occupational Safety and Health Administration. 1910.140 – Personal Fall Protection Systems
A “competent person” under OSHA’s definition is someone who can identify existing and foreseeable hazards in working conditions and who has the authority to take immediate corrective action to eliminate those hazards.4eCFR. 29 CFR 1926.32 – Definitions It is not a formal certification. It means someone with enough training and experience to evaluate whether the harness is still safe, combined with the organizational authority to pull it from service. Many employers designate a site safety manager or supervisor for the role. In practice, most safety managers retire a harness outright after a fall arrest rather than return it to service.
What About the Annual Inspection People Talk About
ANSI/ASSP Z359.2 requires fall protection equipment to be inspected by a competent person other than the user at intervals of no more than one year. Some manufacturers and safety consultants recommend a tighter interval of every six months. These periodic inspections go further than a daily pre-use check: a systematic review of every component, formal documentation, and a pass-or-fail determination on the entire system.
ANSI standards are voluntary consensus standards, not federal law. OSHA does not enforce them directly. They still carry weight for two reasons. First, many employers adopt ANSI Z359 as part of their written fall protection program, which makes compliance an internal policy obligation. Second, if an accident occurs and an employer’s program falls short of recognized industry consensus standards, that gap can factor into litigation and into OSHA’s evaluation of whether the employer maintained a safe workplace. Most employers treat the annual ANSI interval as a floor.
What to Check on Each Inspection
The failure points are the same whether you are doing a quick pre-shift check or a formal periodic inspection. Inspectors who have handled a lot of harnesses focus on a few areas.
Webbing and Stitching
Run every strap through your hands. You are feeling for cuts, fraying, thinning, or stiff spots. Discoloration, scorch marks, or melted areas signal heat or chemical exposure that weakens the synthetic fibers even when the webbing still looks intact on the surface. Excessive hardness or brittleness usually points to UV degradation from long-term sun exposure.5Occupational Safety and Health Administration. Inspection Checklist – Fall Protection Equipment Stitching at load-bearing connection points deserves the closest attention. Broken, pulled, or missing stitches at the D-ring attachment or leg-strap junctions are grounds for immediate removal from service.
Hardware and Labels
Check buckles, D-rings, and adjusters for cracks, distortion, sharp edges, and corrosion. Moving parts should operate freely, and buckles should lock with a positive click. Many newer harnesses include a fall-arrest indicator, a specially engineered section of stitching or folded webbing that deploys visibly when the harness absorbs enough force from a fall. If you see exposed contrasting material, separated stitching, or a deployed marker at the dorsal D-ring attachment, the harness has arrested a fall and must come out of service immediately, even if nothing else looks wrong.
The manufacturer’s label must be legible. It contains the model number, serial number, date of manufacture, and any weight-capacity limits. A harness with a missing or unreadable label cannot be tracked or checked against manufacturer specifications, so it should be pulled from service.
When a Harness Fails Inspection
Any defect found during any inspection, whether a morning pre-use check or a formal annual review, means the harness comes out of service immediately. Tag it or mark it clearly so no one grabs it by mistake. It cannot be used again until a competent person evaluates it and confirms it is undamaged and suitable for continued use.1Occupational Safety and Health Administration. 1910.140 – Personal Fall Protection Systems
If the harness arrested an actual fall, assume it is done. The forces involved stretch and stress webbing and hardware in ways that are not always visible.2eCFR. 29 CFR 1926.502 Repairs should only be performed by the original manufacturer or an entity the manufacturer has specifically authorized. Field repairs with substitute hardware, replacement stitching, or improvised webbing are never acceptable. When a harness is permanently retired, cut the webbing into short pieces so it cannot be scavenged and put back into use. Destroying the D-rings or cutting through the leg straps makes the equipment obviously unusable.
Documenting the Inspection
OSHA’s regulation for the pre-use workshift inspection does not explicitly require written documentation. The practical reality is that you cannot prove an inspection happened without a record. Under ANSI Z359.2, formal periodic inspections must be documented, and most employers extend the same practice to daily checks.
A workable inspection log captures the equipment description, model and serial number, date of manufacture, date of inspection, the inspector’s name and signature, a pass or fail determination for each component, and a final disposition marking the harness as either returned to service or removed from service.5Occupational Safety and Health Administration. Inspection Checklist – Fall Protection Equipment OSHA publishes a sample inspection checklist that follows this format.
Does a Harness Expire?
Neither OSHA nor ANSI sets a fixed expiration date for fall protection harnesses. No rule says “replace every harness after five years” or any other predetermined interval. The only person who can determine when a harness has reached the end of its useful life is a competent inspector who has actually examined it. A harness used daily on a dusty construction site will wear out far faster than one used occasionally in an indoor maintenance setting.
Tracking the date of manufacture and the date of first use still matters. Some manufacturers provide guidance on expected service life for their specific products, and contacting them for that information is worth the effort. If inspection records show progressive wear trending toward failure, that alone justifies retirement even when the harness technically passes today’s check.
Penalties for Skipping Inspections
Fall protection violations are not abstract risks. General fall protection requirements have been the single most cited OSHA standard for fifteen consecutive years, with 5,914 violations recorded in fiscal year 2025 alone. Fines for a serious violation can reach $16,550 per violation. Willful or repeated violations carry a maximum penalty of $165,514 per violation.6Occupational Safety and Health Administration. OSHA Penalties These figures are adjusted for inflation annually. Beyond fines, a failed inspection that leads to a worker’s fall creates legal exposure and outcomes no penalty amount can undo.
