Free checklist

HazCom employer deadline: November 20, 2026

If your workers handle hazardous chemicals, OSHA's updated Hazard Communication Standard asks employers to update workplace labels, the written program and training for substances by this date. This page gives you the dates, a nine step checklist and a small SDS tracker. Everything runs in your browser and saves nothing to a server.

Nine step checklist

These steps follow the action lists in two law firm summaries (Shipman and Goodwin, Robinson and Cole in National Law Review). They are suggestions from those firms, not OSHA requirements by themselves.

Small containers

OSHA says the 2024 update added special labeling provisions for small packages of 100 ml or less, and for very small packages of 3 ml or less (OSHA publication 4437, 2024 final rule). The National Law Review summary tells employers to check small containers against these provisions. Read paragraph (f)(12) of 29 CFR 1910.1200 for the exact text. Do not rely on this page for the details.

What is at stake. Both law firm summaries we cite say serious OSHA violations can carry penalties of up to $16,550 each and willful or repeat violations up to $165,514, and that an inspection can produce several citations when there are many containers or an outdated program or training record. The employer date for substances is November 20, 2026, which is about four weeks from this page being written. Sources: Shipman and Goodwin, Robinson and Cole. Penalty amounts change, so check OSHA for current figures.
