Safety Action Closure Rate Calculator

Use one process, asset or item scope, reporting period, cutoff, measurement unit, and written classification rule across both values. The opening action cohort remains fixed through the review cutoff. Cancelled, merged, transferred, reopened, and verification-pending actions use explicit rules. Reconcile the numerator to the eligible denominator rather than combining separately filtered reports. A changed population can move the percentage even when underlying operations did not change.

The rate describes follow-up completion for one cohort, not hazard removal quality, residual risk, incident frequency, severity, or safety performance. Compare periods or targets prepared from the same rules, not an assumed universal benchmark. Product mix, sampling, schedule changes, reporting delay, exclusions, automation, and event granularity can move the value. Review absolute observations and reason-level evidence beside the percentage before deciding on corrective work.

No. This calculator applies disclosed arithmetic to values you supply; it is not an audit, quality release, maintenance authorization, supplier ruling, forecast, or process certification. Closure counts cannot establish that a hazard is controlled; competent safety review and residual-risk verification remain necessary. Retain source records, version the metric definition, test late-arriving events, and obtain accountable review before using the result for incentives, acceptance, or contractual action.
