About

A cited republication of the rule, plus the log that follows from it

Job13 answers one question properly — is this case recordable under 29 CFR Part 1904 — and shows the provision behind every answer. Then it keeps the 300 Log, 300A summary and ITA export that the answer creates work for.

Who this is for

Three kinds of user

The person who got handed safety
An operations or HR manager at a 30-to-300-person company for whom recordkeeping is a fraction of the job. You need the right answer and the provision behind it, not a course.
EHS managers and consultants
You already know Part 1904. What you need is the audit trail — a defensible record of why each case was classified as it was, and a 300A that computes rather than being typed.
AI agents doing the same work
The engine is a JSON API and a hosted MCP server. An assistant can decide a case mid-task and get back the citation instead of a plausible-sounding guess.

The honesty posture

What we will not do to make this look better

These are constraints on the product, not aspirations. Each one costs us something — a cleaner answer, a nicer number, a shorter page — and each one is the reason the output is worth citing.

We quote; we do not paraphrase: Every provision shown on this site is the eCFR's own text. Where we explain something in our own words, it is visually and structurally separated from the regulation, and labelled as ours.
Needs review beats a tidy answer: Part 1904 leaves real questions to judgement. When a fact that could change the outcome is unknown, the engine returns needs review and names what must be resolved — it never assumes “no” to reach a clean verdict.
No uncited assertion: Every decisive step in a determination carries verbatim regulation text and a link to the source. If we cannot quote it, we do not claim it.
No flattering blanks: With no hours worked, an incidence rate reads “No data” rather than 0.00. An absent measurement is never rendered as a good result.
Determinations stay on your machine where they can: The free recordability check and the rate calculator run entirely in your browser. Incident facts are employee medical information, and they do not need to travel for us to answer the question.

This is not legal advice

Job13is an administrative classification aid. It is not a law firm, it does not give legal advice, and using it does not create any professional relationship. The duty to record and report under 29 CFR Part 1904 remains the employer’s, and so does responsibility for the accuracy of what goes on the log. For a consequential or contested case — and certainly for anything touching an inspection, a citation or litigation — take advice from a qualified professional. We are not affiliated with or endorsed by OSHA or the U.S. Department of Labor.

Where the data comes from

Provenance, in full

You should be able to check us. Here is exactly what we hold, when we retrieved it, and under what terms.

Source: The eCFR (Electronic Code of Federal Regulations) API, Title 29, Part 1904 — the official, continuously updated version of the CFR published by the Office of the Federal Register and the Government Publishing Office.
Edition: 2026-01-01
Retrieved: 2026-07-19
What we hold: 31 sections parsed into paragraphs and tables, the exhaustive first-aid list at 1904.7(b)(5)(ii), the 9 work-relatedness exceptions at 1904.5(b)(2), and the 82 partially exempt industries in Appendix A to Subpart B.
Copyright: The regulation is a work of the United States Government and is in the public domain under 17 U.S.C. 105. We add no rights to it and claim none over it.
Worked scenarios: 14 scenarios, each decided at build time by the same engine that powers the free check and the API — so a published example cannot contradict the product.

The eCFR is itself unofficial for legal purposes; the official text is the annual Code of Federal Regulations. Where currency matters to a decision, check the eCFR link on any section page — we publish the edition and retrieval date on every one of them so a stale copy is visible rather than silent.

Corrections

Tell us if we are wrong

If a quoted provision does not match the eCFR, if a determination reaches a conclusion the rule does not support, or if a scenario reads as advice rather than an example, we want to know — those are defects, not opinions. Email hello@job13.com.

Read the rule we publish

Not legal advice. This page republishes 29 CFR Part 1904 as published by the eCFR and explains it. The recordkeeping duty is the employer’s. Where the rule requires judgement, Job13 says so rather than guessing — run your own case through the free check.
