The Hazard Communication Standard (HazCom) under Title 8 CCR §5194 requires that, for every hazardous chemical in the workplace, the employer must maintain:

Explanation

Section 5194 requires all four together: a written hazard communication programme listing the hazardous chemicals present; labels on containers in the workplace; a safety data sheet for each chemical, readily accessible to employees in their work area during each work shift; and training. Option (b) is the commonest real-world shortfall - the binder exists but it is in the trailer, and accessibility is measured from where the worker is standing when they need it. Option (c) treats the written programme as paperwork that can be skipped; it is the first document the Division asks for. Option (d) borrows a quantity threshold from transportation and fire-code placarding; hazard communication has no such floor, and a single quart of a hazardous chemical carries the full set of duties.
