Comparison: State vs. Federal
• Rules. Washington's hazard communication rules mirror federal regulations, except that the state has adopted rules for biological agents, HAZWOPER training and education, container labeling, Material Safety Data Sheet/Safety Data Sheet (MSDS/SDS), and hazardous substance fees that are stricter than federal rules. Certain employers must pay fees annually according to specified standard industrial codes (SICs) that are applicable to facilities that report at least 10,400 worker hours to the Washington Department of Labor and Industries (DLI). Reasonable efforts must be made by an employer to post notices in employees' native languages. The DLI provides written hazard communication program language translation services to employers. The effective dates of the new hazard communication rule will be delayed and phased in. The effective completion date to train employees on the new label elements and SDS format is 6 months later than the federal requirement.
