AI-Generated OSHA 300 Log Analysis: Catch Errors Before an Inspector Does

The Problem Nobody Talks About Until It's Too Late

Every year, around February, the same scene plays out in EHS offices across the country. The Safety Manager — or whoever drew the short straw — sits down with a spreadsheet, a copy of the OSHA 300 log, and a stack of incident reports from the past twelve months. They're trying to confirm that every recordable case is logged correctly before the OSHA 300-A summary gets posted on February 1st.

It sounds manageable. It isn't.

A mid-sized manufacturing facility with 200 employees might have 30 to 60 incident reports to cross-reference. Each one needs to be checked against the criteria in 29 CFR 1904.7 (general recording criteria), 29 CFR 1904.5 (work-relatedness), and the case type classifications under 29 CFR 1904.46. Days Away, Restricted, Transferred — DART cases — need to be counted correctly. Privacy cases under 29 CFR 1904.29(b)(6) need to be anonymized properly. Near-misses that shouldn't be on the log sometimes are. Recordables that should be there sometimes aren't.

One misclassification — a restricted work case logged as first aid, or a days-away case where the day count is wrong — can result in a citation under 29 CFR 1904 Subpart C. And OSHA inspectors know exactly where to look.

Why Manual Review Fails Consistently

The core issue isn't effort. EHS professionals doing this work are experienced and conscientious. The issue is that manual cross-referencing at volume is exactly the kind of task where human attention degrades. By the fifteenth incident report, you're skimming. By the thirtieth, you're trusting your memory of what the criteria say instead of checking again.

There are also structural problems. Incident descriptions written by supervisors or HR often leave out details that matter for classification — whether a physician made a recommendation, whether restrictions were employer-assigned versus medically directed, whether the injury was personal in nature and therefore not work-related under 29 CFR 1904.5(b)(2). A human reviewer has to notice what's missing. That requires reading carefully, knowing what to look for, and having time to follow up. Most EHS teams have none of those things in abundance during year-end close.

Most safety managers assume that OSHA recordkeeping errors are obvious — things like forgetting to fill in a column or miscounting lost days. But the reality is that the most common and costly errors are classification errors buried in the narrative: cases that were borderline recordable and got logged as first aid, or restricted-duty cases where the nature of the restriction was never documented clearly enough to defend.

What Gerty Does — Step by Step

Gerty is an AI compliance platform built specifically for EHS work. When you connect your incident management data or upload your OSHA 300 log and the underlying incident reports, here's what happens:

• Automated recordability screening: Gerty reads each incident record and applies the 29 CFR 1904.7 criteria systematically — checking for medical treatment beyond first aid, days away, restricted work, job transfer, loss of consciousness, and diagnosis of a significant injury or illness. It flags every case where the current classification doesn't match what the record supports.
• DART rate calculation and validation: Gerty calculates your Days Away, Restricted, or Transferred rate automatically and checks it against your logged headcount and hours. Errors in the denominator — one of the most common audit findings — get caught before they compound.
• Privacy case identification: Gerty scans for injury types that require privacy protection under 29 CFR 1904.29(b)(6) — sexual assaults, mental illness, HIV-related cases, and others — and flags any where an employee name appears in a field that should be anonymized.
• Missing or incomplete record detection: Gerty identifies incidents in your source data that appear to meet recordability criteria but don't have a corresponding entry on the 300 log, and vice versa — entries on the log with no supporting incident documentation.
• Narrative inconsistency alerts: Using natural language processing, Gerty reads incident descriptions and medical notes and flags language that suggests a classification may be wrong — phrases like "physician recommended light duty" appearing in a case logged as first aid, for example.

The output is a structured exception report that an EHS Manager or Safety Director can work through systematically. Each flagged item includes the specific regulatory basis for the concern, the relevant section of the record, and a recommended action. No guessing. No hunting through the CFR.

A Real Scenario

A regional distribution company with three facilities ran their 2024 OSHA 300 logs through Gerty in January 2025. Gerty flagged 11 potential issues across 47 total recorded cases. Of those, the EHS Director confirmed 7 were actual errors: two cases where restricted duty had been documented in the incident report but the log showed "days away from work," inflating the severity classification; three first-aid-only cases that should have been logged as recordables based on the physician visit notes; and two cases where employee names appeared in the injury description column on privacy-protected case types.

None of those errors would have been caught in a standard manual review. All of them would have been visible to an OSHA compliance officer conducting an inspection under 29 CFR 1904.40.

What Gerty Doesn't Replace

This matters, so it gets its own section.

Gerty flags issues and surfaces evidence. It does not make final recordability determinations on your behalf, and it doesn't replace the judgment of a qualified EHS professional or legal counsel on ambiguous cases. If a case is genuinely borderline — a work-related aggravation of a pre-existing condition under 29 CFR 1904.5(a), for example — Gerty will tell you the case is flagged and why. It will not tell you the answer, because that decision involves facts and context a human needs to own.

Gerty also does not submit your 300-A summary, contact OSHA on your behalf, or provide legal advice. It is a tool that makes the EHS professional doing this work faster, more consistent, and harder to catch off guard during an inspection.

Frequently Asked Questions

How is AI better than just having someone carefully review the log manually?

Manual review accuracy drops with volume and fatigue. Gerty applies the same criteria to the first record and the fiftieth record with identical consistency. It also reads across multiple data sources simultaneously — the 300 log, incident reports, and medical documentation — which a human reviewer typically does sequentially and incompletely under time pressure.

Does Gerty work with our existing incident management system?

Gerty is designed to integrate with common EHS and incident management platforms, and also accepts direct file uploads for organizations that manage records in spreadsheets or PDFs. The specific integrations available are listed at gerty.ai.

What regulations does Gerty's OSHA 300 analysis cover?

The analysis covers the full 29 CFR 1904 recordkeeping framework — recording criteria under 1904.7, work-relatedness under 1904.5, privacy case handling under 1904.29, and the DART rate calculations required for the 300-A summary. Gerty is updated when OSHA interpretive guidance or regulatory changes affect these standards.

When should we run this analysis — only at year-end?

Year-end is the highest-stakes window, but running quarterly reviews gives you a much smaller correction window and prevents errors from compounding. An EHS Manager who catches a misclassification in October has time to fix it cleanly. One who finds it in January is correcting the record under time pressure before the 300-A posts.

Can Gerty help if we're already under OSHA inspection?

Gerty can help you understand what's in your records quickly. However, if you are under active OSHA inspection or citation, you should involve qualified legal counsel. Gerty is a compliance preparation tool, not a response tool for enforcement actions.

OSHA recordkeeping citations are among the most preventable findings in EHS compliance — and among the most embarrassing, because they signal to an inspector that your entire program may lack rigor. The errors that trigger them aren't complicated. They're just easy to miss when you're doing this work manually at volume, under deadline, with everything else on your plate.

Gerty exists to close that gap. Start a free Gerty trial and run your OSHA 300 log through an AI analysis before the next inspector does it for you.
