Module 6 of 7 · ISO 45001 · Clause 9

Performance evaluation

This clause forces safety into real data: accident-rate indicators, incident investigation, internal audits and management review.

Content reviewed on

Monitoring and measuring performance

Determine what needs monitoring —frequency and severity rates, legal compliance, health surveillance results— and evaluate the system's performance.

Incident investigation

Investigate accidents and incidents to identify root causes, not just the immediate cause, and determine actions to prevent recurrence.

Internal audit and management review

An internal audit programme for the OH&S system, and management review with specific inputs such as worker participation and investigation results.

What an auditor usually asks for

  • Up-to-date frequency and severity rates
  • An accident and incident investigation log with root cause
  • A completed internal audit programme for the OH&S system
  • Management review minutes containing the standard's specific inputs

How to cover performance evaluation in Kimobox

  1. 1Set up accident-rate indicators to calculate themselves from logged reports.
  2. 2Log every accident investigation with its root cause and associated actions.
  3. 3Prepare management review with OH&S data already aggregated.

Accident-rate indicators stop being calculated by hand every quarter.
