WISHA HazCom: Washington’s WAC 296-901

No. WAC 296-901-14020 sets July 20, 2026 for substances — employers, chemical manufacturers, importers and distributors alike — which is four months earlier than the federal November 20, 2026 employer date — though two months later than the federal May 19, 2026 manufacturer date, since Washington does not split the two — and is already in the past. Washington's rule was filed December 30, 2025 (WSR 26-02-011, effective February 1, 2026), weeks before federal OSHA extended every HCS 2024 date by four months on January 15, 2026, and Washington did not adopt that extension. Its mixture dates are shifted the same way: manufacturers July 19, 2027 and employers January 19, 2028. A multi-state employer cannot apply one date across a Washington jobsite and a federal-jurisdiction one.

Not by that name. Washington enforces hazard communication through its own rule, Chapter 296-901 WAC, administered by L&I under WISHA. The substance tracks the federal standard — same written program elements, same labeling and SDS duties, same GHS alignment — but the citations differ, and one Washington provision has no federal equivalent at all.

The written program is WAC 296-901-14010, labels and other forms of warning are 296-901-14012, safety data sheets are 296-901-14014, and employee information and training is 296-901-14016. If you are answering a Washington citation or writing a Washington program, those are the numbers to use — the federal paragraph letters do not appear in the state rule.

Yes, and it is the clearest thing Washington offers that federal HazCom does not. Under WAC 296-901-14014(11), the Department of Labor & Industries will translate certain hazard communication documents upon written or verbal request, within available resources, into Cambodian, Chinese, Korean, Spanish or Vietnamese. There is no comparable provision anywhere in 29 CFR 1910.1200.

No — and this is a point where Washington is often assumed to be stricter than it is. WAC 296-901-14012(10) says an employer with employees who speak other languages may add that language as long as the information is also presented in English. That is word-for-word the federal rule at 1910.1200(f)(10). The additional language is permitted, not required, in both regimes.

No. Washington sets no penalty override — L&I applies the federal maximums, so a serious violation caps at $16,550 and willful or repeat at $165,514, the same as a federal-jurisdiction state. What is distinctive is enforcement volume rather than the ceiling: in FY2025 construction enforcement Washington wrote more citations than any other state plan.

Substantively, yes — and that is the useful answer. Unlike California or Michigan, Washington does not add obligations your federal program is missing. What it needs is renumbering: cite the 296-901 sections rather than the CFR paragraphs, and tell a multilingual workforce that L&I translation is available. If you operate in several state-plan states, Washington asks the fewest programme changes — but not the latest deadline: check its date first.
