Occupational Safety and Health Administration
US Department of Labor agency enforcing worker-safety standards; its Hazard Communication Standard (29 CFR 1910.1200) is the federal rule behind the employee-protection half of hazardous-drug handling.

WHAT OSHA COVERS
The Occupational Safety and Health Administration (OSHA) is the agency of the US Department of Labor that sets and enforces workplace safety and health standards. Its general-industry standards are codified at 29 CFR Part 1910. The one a GxP site meets first is the Hazard Communication Standard, 29 CFR 1910.1200. It requires chemical manufacturers and importers to classify the hazards of what they produce or import, distributors to pass that information on, and every employer to maintain a written hazard communication programme, labels, safety data sheets, and employee training. Drugs are covered unless they are in solid, final form for direct administration to the patient. OSHA's hazardous-drugs guidance points to this standard, together with 1910.1020 on access to exposure and medical records and 1910.1450 on laboratories.
WHAT OSHA PUBLISHES
- 0129 CFR 1910 general-industry standards, including the Hazard Communication Standard (1910.1200)
- 02Final rules and corrections in the Federal Register — the HCS update of 20 May 2024 aligned with GHS Revision 7
- 03Letters of interpretation and the HCS inspection directive (CPL 02-02-079)
- 04Safety and health topic pages, including hazardous drugs, with the standards that apply
HOW ITS REQUIREMENTS BITE
OSHA enforces through inspection and citation under the Occupational Safety and Health Act. States may instead run OSHA-approved State Plans, which must be at least as effective as federal OSHA and may be stricter: OSHA lists 22 State Plans covering private-sector and public workers, and seven covering only state and local government workers. A pharmaceutical plant or compounding pharmacy can therefore answer to a state agency, not federal OSHA, for the same hazard communication obligations.
What practitioners get wrong
- USP <800> protects the product, the patient and the worker within pharmacy practice; the HCS is the federal law that obliges the employer to tell and train the worker. A hazardous-drug programme needs both.
- The 2024 HCS rule has staggered compliance dates, and OSHA moved all four back four months in January 2026: substances by 19 May 2026 for classifiers and 20 November 2026 for employers; mixtures by 19 November 2027 and 19 May 2028.
- The solid-final-form exemption ends as soon as a tablet is crushed, split for compounding, or handled as an API, so manufacturing and compounding operations are in scope.
- In a State Plan state, check the state's version of the standard. It may differ from 29 CFR 1910.1200.
WHERE IT SITS INTERNATIONALLY
The HCS is the US implementation of the UN Globally Harmonized System of Classification and Labelling of Chemicals, primarily Revision 7 since the 2024 rule. OSHA coordinates labelling with Health Canada through the Regulatory Cooperation Council and with PHMSA on bulk-shipment labels. It sits outside the FDA framework: FDA governs the drug, and OSHA governs the employee who makes or handles it.

OSHA: frequently asked questions
Reference answers on Occupational Safety and Health Administration’s mandate, what it publishes, and how its requirements acquire force.
Does OSHA's Hazard Communication Standard apply to drugs?
Yes, with exemptions. Drugs in solid, final form for direct administration to the patient (tablets, pills), drugs packaged for retail sale to consumers, and drugs for employees' personal use are exempt. Other drugs that pose a health hazard are covered and must appear in the employer's hazard communication programme.
What changed in the 2024 Hazard Communication Standard?
The final rule published on 20 May 2024 and effective 19 July 2024 aligned the HCS with GHS Revision 7, revised classification criteria, label-update provisions, small-container labelling, trade-secret provisions and safety data sheet content. A January 2026 rule extended each compliance date by four months.
What are the HCS 2024 compliance dates?
As extended in January 2026: manufacturers, importers and distributors evaluating substances by 19 May 2026, employers for substances by 20 November 2026; for mixtures, 19 November 2027 and 19 May 2028 respectively.
