HazCom 2026 Deadline Checklist
Use this before November 20, 2026. OSHA's updated Hazard Communication Standard (HCS 2024, aligned with GHS Revision 7) requires every employer to bring its labels, written program, and training up to the new format by then. Here is everything to check off — print it, work through it, and you'll be ready. (Full background is in our OSHA HazCom 2026 deadline guide.)
Free, no signup: the OSHA HazCom self-audit at sdsentry.0xpi.com/hazcom-self-audit.html scores your Hazard Communication program against 29 CFR 1910.1200 in about two minutes and names the specific gaps.
1. Chemical inventory & safety data sheets
- List every hazardous chemical on site (do each location separately).
- Confirm you have the most recent SDS your supplier has provided for every product, and file updated sheets as they arrive with shipments.
- If a sheet is missing, request it from the supplier in writing. HCS 2024 does not require you to request new sheets for products you already have sheets for (OSHA directive CPL 02-02-079).
2. Labels
- Check that shipped containers carry a compliant GHS label (pictograms, signal word, hazard & precautionary statements).
- Label every secondary container — spray bottles, decanted product, refill jugs — with at least the product name and the hazard information.
3. Written HazCom program
- Have a written Hazard Communication program (required by 29 CFR 1910.1200(e)).
- Update it to reflect the current standard, your chemical list, and how you label, store, and train.
4. Employee training
- Train every employee on the revised GHS label elements and the SDS format.
- Train new hires before they work with hazardous chemicals, and whenever a new hazard is introduced.
- Document who was trained, on what, and when — and keep the records.
5. Access
- Make sure SDSs are readily accessible to employees on every shift.
- Have a backup for an internet or power outage (printed copies or offline access).
6. Hit the deadline
- Everything above complete for substances by November 20, 2026.
- Plan for the parallel mixtures deadline of May 19, 2028.
