4.5.1 Performance Measurement and Monitoring Accidents, Incidents, Non-conformances and Corrective and Preventive Action Records and Records Management Audits

3. 4.5.1 Performance Measurement and Monitoring
The organisation must institute and maintain procedures for regularly monitoring and measuring OH&S performance. These procedures must comprise the following:
Qualitative and quantitative measurements based on the organisation's requirements
Monitoring the extent to which the organisation's OH&S objectives are being achieved
Proactive performance measurements that monitor conformance with the OH&S management programme, the criteria for operational sequences, and the prevailing laws and regulations

4. Reactive performance measurements for monitoring accidents, illneses, incidents (including near-accidents) and other evidence of negative OH&S performance
Recording of the data and results of the monitoring and measurements to the extent that they can facilitate the future analysis of correction and preventive actions.
If certain instruments are required for measuring and monitoring performance, the organisation must institute and maintain procedures for calibrating and servicing the instruments. It must retain verification of these calibration and servicing activities.
