How this service works
OSHA Permissible Exposure Limits (Table Z-1, 29 CFR 1910.1000, read from eCFR): chemical name, CAS number, 8-hour TWA in ppm and mg/m3, and notes such as ceiling or see-other-section. Matches by name words. Up to 20 chemicals per call; not the full OSHA chemical database.
Output
Returns up to 20 matching chemicals from OSHA Table Z-1, each with chemical name, CAS number, 8-hour TWA in ppm and/or mg/m³, and notes such as ceiling designations or cross-references to other OSHA sections. Results are matched by name words against the eCFR 29 CFR 1910.1000 dataset.
Example use cases
Industrial hygiene compliance check
“We're running an air quality audit at our paint shop — can you pull the OSHA Table Z-1 permissible exposure limits for xylene, toluene, and acetone? I need the 8-hour TWA in ppm and mg/m³ for each.”
Chemical safety data sheet review
“I'm reviewing safety procedures for our lab. What are the OSHA PELs for formaldehyde and methanol under 29 CFR 1910.1000? Include any ceiling limits or special notes.”
Worker exposure risk assessment
“Can you look up the OSHA permissible exposure limits for up to 5 chemicals — benzene, styrene, ethylbenzene, chloroform, and carbon tetrachloride — and show me the TWA values and CAS numbers from Table Z-1?”
Technical details
Endpoint
GEThttps://api.healthtravel-api.workers.dev/api/health/osha-occupational-health?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need official OSHA regulatory exposure limits (PELs) from 29 CFR 1910.1000 Table Z-1 specifically, including TWA values in both ppm and mg/m³ and ceiling notations. Prefer this over general chemical databases when you need regulatory compliance data cited by OSHA standard. Note it covers only Table Z-1 (up to 20 chemicals per call) and not the full OSHA chemical database or Tables Z-2/Z-3.
Side effects
- Chemical name not found in Table Z-1 (returns empty results or no match)
- Query string too short (under 3 characters) or too long (over 60 characters) causes validation error
- max parameter out of range (must be 1–20) may cause error or be clamped
- Chemical only listed in a different OSHA table (Z-2 or Z-3) not covered by this endpoint
- Partial name matches may return irrelevant chemicals if name words are ambiguous
- Payment failure or x402 authentication error prevents response
