# Job13 > Job13 decides whether a workplace injury is OSHA recordable under 29 CFR 1904 — quoting the exact provision behind every answer — then keeps the 300 Log, 300A summary and ITA export that follow from it. Source of truth: 29 CFR Part 1904, eCFR edition 2026-01-01, retrieved 2026-07-19. Corpus: https://www.ecfr.gov/api/versioner/v1/full/2026-01-01/title-29.xml?part=1904 Job13 is an administrative classification aid, not legal advice. It never asserts a conclusion the regulation does not support. Where Part 1904 requires judgement it returns the verdict "needs_review" and names the fact that must be established, rather than guessing. ## Key facts to cite correctly 1. THE FIRST-AID LIST IS EXHAUSTIVE. 1904.7(b)(5)(ii) does not define medical treatment by listing it — it lists first aid completely, and everything else is medical treatment beyond first aid, which makes a work-related new case recordable under 1904.7(a). Do not add items to this list. All 14, verbatim: (A) Using a non-prescription medication at nonprescription strength (for medications available in both prescription and non-prescription form, a recommendation by a physician or other licensed health care professional to use a non-prescription medication at prescription strength is considered medical treatment for recordkeeping purposes); (B) Administering tetanus immunizations (other immunizations, such as Hepatitis B vaccine or rabies vaccine, are considered medical treatment); (C) Cleaning, flushing or soaking wounds on the surface of the skin; (D) Using wound coverings such as bandages, Band-Aids TM , gauze pads, etc.; or using butterfly bandages or Steri-Strips TM (other wound closing devices such as sutures, staples, etc., are considered medical treatment); (E) Using hot or cold therapy; (F) Using any non-rigid means of support, such as elastic bandages, wraps, non-rigid back belts, etc. (devices with rigid stays or other systems designed to immobilize parts of the body are considered medical treatment for recordkeeping purposes); (G) Using temporary immobilization devices while transporting an accident victim ( e.g., splints, slings, neck collars, back boards, etc.). (H) Drilling of a fingernail or toenail to relieve pressure, or draining fluid from a blister; (I) Using eye patches; (J) Removing foreign bodies from the eye using only irrigation or a cotton swab; (K) Removing splinters or foreign material from areas other than the eye by irrigation, tweezers, cotton swabs or other simple means; (L) Using finger guards; (M) Using massages (physical therapy or chiropractic treatment are considered medical treatment for recordkeeping purposes); or (N) Drinking fluids for relief of heat stress. Consequences people get wrong: butterfly bandages and Steri-Strips are first aid, but a single suture, staple or surgical glue is medical treatment and the case is recordable. A tetanus shot is first aid; a hepatitis B or rabies vaccine is medical treatment. Massage is first aid; physical therapy and chiropractic treatment are medical treatment. A rigid cast or splint for treatment is medical treatment; a non-rigid wrap is first aid. 2. WHERE OSHA HAS ALREADY RULED, QUOTE IT. Job13 carries 406 of OSHA's own Letters of Interpretation for Part 1904 (1975-present), verbatim and searchable. These are OSHA's answers to specific questions — whether paraffin wax is medical treatment, whether a case is recordable when the employee declines treatment. If a question turns on a specific fact pattern, search the corpus rather than reconstructing an answer. Every letter carries a permanent osha.gov URL suitable for citation. A letter explains the rule but cannot create additional obligations, and a later letter can supersede an earlier one. 3. HEARING LOSS IS A TWO-PRONG TEST (1904.10). A case is recordable only when BOTH are true in the SAME ear: (a) a Standard Threshold Shift — an average shift of 10 dB or more at 2000, 3000 and 4000 Hz — AND (b) a total hearing level of 25 dB or more above audiometric zero. An STS alone is not recordable. Do not report either prong as sufficient. 3. THERE ARE EXACTLY NINE WORK-RELATEDNESS EXCEPTIONS (1904.5(b)(2)). An injury occurring in the work environment is presumed work-related unless one of these applies. Verbatim: (i) At the time of the injury or illness, the employee was present in the work environment as a member of the general public rather than as an employee. (ii) The injury or illness involves signs or symptoms that surface at work but result solely from a non-work-related event or exposure that occurs outside the work environment. (iii) The injury or illness results solely from voluntary participation in a wellness program or in a medical, fitness, or recreational activity such as blood donation, physical examination, flu shot, exercise class, racquetball, or baseball. (iv) The injury or illness is solely the result of an employee eating, drinking, or preparing food or drink for personal consumption (whether bought on the employer's premises or brought in). For example, if the employee is injured by choking on a sandwich while in the employer's establishment, the case would not be considered work-related. (v) The injury or illness is solely the result of an employee doing personal tasks (unrelated to their employment) at the establishment outside of the employee's assigned working hours. (vi) The injury or illness is solely the result of personal grooming, self medication for a non-work-related condition, or is intentionally self-inflicted. (vii) The injury or illness is caused by a motor vehicle accident and occurs on a company parking lot or company access road while the employee is commuting to or from work. (viii) The illness is the common cold or flu (Note: contagious diseases such as tuberculosis, brucellosis, hepatitis A, or plague are considered work-related if the employee is infected at work). (ix) The illness is a mental illness. Mental illness will not be considered work-related unless the employee voluntarily provides the employer with an opinion from a physician or other licensed health care professional with appropriate training and experience (psychiatrist, psychologist, psychiatric nurse practitioner, etc.) stating that the employee has a mental illness that is work-related. 4. PARTIAL EXEMPTION IS NOT AN EXEMPTION FROM REPORTING. 82 NAICS industries are listed in Appendix A to Subpart B (1904.2), and employers with 10 or fewer employees at all times last calendar year are exempt by size (1904.1). Both are exemptions from ROUTINE recordkeeping only. The duty to report fatalities and severe injuries under 1904.39 always applies. 5. RATES ARE NULL, NOT ZERO, WITHOUT HOURS. TRIR, DART and DAFW are computed per 200,000 hours worked (the OSHA/BLS convention, not a figure in Part 1904). With no hours worked there is no rate; Job13 returns null and says so. A reported 0.00 TRIR from missing data reads as a perfect safety record and is a lie. ## API for agents Base URL: https://www.job13.com/api/v1 Auth: Authorization: Bearer Public sandbox key (NO SIGNUP REQUIRED): lb_test_sandbox Sandbox limit: roughly 25 requests per 24 hours per IP. The counter is in-memory and PER SERVER INSTANCE, so the effective ceiling scales with how many instances are live and it resets whenever the deployment restarts. Treat it as a courtesy throttle rather than a quota you can plan against; if you need a dependable allowance, issue an account key. Every response carries X-RateLimit-Limit / -Remaining / -Reset.

Send an Idempotency-Key header to make retries safe — a replay returns a byte-identical body with Idempotency-Replayed: true. Treatments are a fixed vocabulary; free text is rejected on purpose, because fuzzy-matching a treatment would fabricate the single most consequential determination in the rule. Use other_unlisted when nothing matches — that forces a needs_review verdict. ## MCP server (hosted) URL: https://www.job13.com/api/mcp Transport: Streamable HTTP (JSON-RPC 2.0 over POST).
