OSHA 1910.23 does not mandate a specific inspection interval for fixed ladders, but OSHA’s General Duty Clause requires employers to provide a workplace free from recognized hazards — and a corroded, loose, or damaged fixed ladder is a recognized hazard. Similarly, EN ISO 14122-4 and AS 1657 require that fixed access equipment be maintained in a safe condition, which implies periodic inspection.
This article provides a structured inspection checklist that safety officers, facility managers, and maintenance teams can use for annual (or more frequent) inspections of fixed steel ladders and caged ladders. The checklist is organized by inspection zone — from the foundation to the top landing — and includes acceptance criteria with clear pass/fail guidance.

Inspection Frequency Recommendations
| Environment | Recommended Minimum Frequency | Notes |
|---|---|---|
| ———— | —————————— | ——- |
| Indoor, non-corrosive | Annually | Visual inspection sufficient |
| Outdoor, non-coastal | Annually | Pay attention to bracket and anchor condition |
| Coastal (within 5km) | Every 6 months | Check for coating degradation and early corrosion |
| Chemical / process areas | Every 3-6 months | Frequency depends on chemical exposure severity |
| After severe weather (hurricane, earthquake) | Immediately | Structural inspection before returning to service |
| After any impact (vehicle, equipment strike) | Immediately | Check for deformation or cracking |
Pre-Inspection Preparation

| Verify ladder is safe to climb | Before ascending, visually check from ground: any obvious missing rungs, severe corrosion, structural deformation? |
| Clear area below ladder | Ensure no personnel, equipment, or materials are in the fall zone during inspection |

Post-Inspection Actions
1. File the completed inspection report in the facility’s safety documentation system. Retain for a minimum of 5 years (the ladder warranty period).
2. Tag any ladder that fails inspection as OUT OF SERVICE at both the base and the landing level.
3. Schedule repairs for all defects, prioritizing critical items for immediate action.
4. Photograph all defects before and after repair for the maintenance record.
5. Re-inspect repaired ladders before returning them to service.
6. Update the ladder asset register with the inspection date, result, and next scheduled inspection.

Frequently Asked Questions
1. Can I do the annual inspection myself, or does it require a certified inspector?
OSHA does not require a specific certification for ladder inspectors. The standard requires inspection by a “competent person” — someone capable of identifying existing and predictable hazards in the working environment. For most facilities, a trained maintenance technician or safety officer qualifies. External certified inspectors may be required by insurance policies, local building codes, or corporate safety policies. The key is competence, not certification — the inspector must know what to look for and how to evaluate findings against acceptance criteria.
2. What do I do if a ladder fails an inspection item?
The action depends on severity. For minor issues (surface rust on HDG, loose bolt, missing cage tag): document and schedule repair within 30 days. For moderate issues (bent cage hoop, moderate corrosion, loose anchor): tag the ladder “RESTRICTED USE” with any applicable limitations, document, and schedule repair within 7 days. For critical issues (cracked weld, bent stile, failed anchor, severe corrosion): tag “DO NOT USE,” barricade the base, and contact the manufacturer immediately. Never allow use of a ladder with a known structural defect.
3. How long should inspection records be kept?
OSHA requires retention of inspection records for the duration of the ladder’s service life plus 5 years. For a ladder with a 25-year service life, that is 30 years of records. Maintain a ladder log for each installed ladder, recording: installation date, inspection dates, inspector name, findings, corrective actions, and replacement parts used. Digital record-keeping (spreadsheet or CMMS) is acceptable. For facilities with many ladders, a ladder asset register with unique ID tags on each ladder simplifies tracking.

FAQ
Q: How often should I inspect my fixed ladders?
OSHA requires periodic inspection but does not specify the exact interval. Industry best practice is annual formal inspection with more frequent visual checks (quarterly or monthly) for high-use ladders. After extreme weather events, seismic activity, or physical impacts, perform an immediate inspection.
Q: What should I do if an inspection finds damage?
Document the findings with photos and measurements. Categorize the damage: (A) cosmetic only — no action required; (B) minor — repair within 90 days and re-inspect; (C) major — take the ladder out of service immediately and repair or replace. For uncertain cases, send photos to our engineering team for assessment.
