This guide is a working reference to workplace safety law for employers, workers, and the counsel who advise both. It sets out the statutory architecture, distinguishes specific standards from the general duty clause and states the four elements of a general duty citation, and explains how standards are made, challenged, and varied. Procedural chapters follow a matter from complaint through inspection, citation, informal conference, contest, and review commission adjudication, with the warrant question and the scope negotiation that decide how much an inspection produces. Classification and penalty chapters explain what moves a citation up the ladder and why the abatement obligation outlasts the fine. Separate chapters treat the anti-retaliation provision and its thirty-day deadline, the narrow protected refusal, the four multi-employer roles, and recordkeeping with its short severe-event reporting deadlines. Program chapters supply a hazard assessment method organized around the five categories that cause most serious harm. Reference tables close the guide with every authority linked to its text.
