preventive-action

Preventive action is a structured safety practice that identifies, evaluates, and eliminates the root causes of potential nonconformities or hazards before they materialize into actual incidents. It operates prospectively rather than reactively: the procedure triggers when risk assessments, trend analyses, audit findings, or hazard reviews surface conditions that *could* cause harm, and prescribes targeted interventions to remove those conditions from the operational environment. Unlike corrective action, which addresses a nonconformity that has already occurred, preventive action targets the causal chain upstream. Its persistence mechanism is organizational: codified in safety management systems (e.g., ISO 45001 procedures), documented in standard operating protocols, and enforced through management review cycles that verify the action was taken and evaluate its effectiveness. The practice is explicit — it is written, taught, audited, and measured — and persists across organizational memory through documented procedures, training programs, and institutional routines that outlast individual practitioners.
