When James Morrison accepts a regional Safety Excellence Award for eighteen months without a lost-time injury, he believes he has built something real. A culture where safety matters. A system that works.That same night, Danny Chen is injured in the warehouse.The warehouse that wasn't in scope.Exposure follows the aftermath of a preventable incident at a manufacturing company - the regulatory investigation, the hard conversations, and the systematic rebuilding of a safety management system that looked adequate on paper but failed in practice. Told through the people who lived it - a warehouse supervisor who reported a hazard nobody acted on, a union representative who'd seen this before, a safety coordinator who knew the standard but not the operation, and a CEO who finally understood what accountability actually meant.Each chapter maps directly to a clause of ISO 45001:2018, the international standard for occupational health and safety management systems. The story doesn't simplify the standard - it makes it real. Scope. Normative references. Terms and definitions. Context. Leadership. Planning. Support. Operation. Performance evaluation. Improvement. Ten clauses. One organisation learning what it actually means to keep people safe.A Framework Reference Guide at the back maps every story event to its ISO 45001 requirement, making Exposure a practical companion for anyone implementing or auditing an occupational health and safety management system.Part of the Collision Series - teaching international standards in practice.
