Critical risk

A risk that can kill or cause permanent harm; the risks a critical risk programme names and controls.

Critical risk programmes and life-saving rules name the fatal risks and specify their controls. In energy terms, most critical risks are high-energy hazards. EBS adds the energy model that lets a crew recognise those risks in an unfamiliar task, and the Direct Control test that tells them whether the listed control is actually doing the job on the day. From 1 April 2027 New Zealand’s Health and Safety at Work Act, as amended in 2026, directs PCBUs to prioritise critical risks.
