Every major accident in the process industries shares one root cause: hazards that were known, and risks that were not adequately controlled. Bhopal. Texas City. Piper Alpha. Buncefield. In each case, process hazard analysis tools existed that could have identified the failure modes before the event. HAZOP and LOPA exist precisely to prevent these outcomes — and in regulated industries, conducting them is not optional. This course is the complete practical guide to HAZOP and LOPA for process, safety, and C&I engineers.
HAZOP — Hazard and Operability Study — is the primary technique for identifying hazards in process plant design. It is required by IEC 61511 as part of the functional safety lifecycle, by OSHA PSM for covered processes in the United States, and by COMAH for major hazard sites in the UK. If you are working on any process plant, pipeline, or offshore installation, HAZOP is not optional — and knowing how it works at a practitioner level is a professional requirement.
