Control measures must be reviewed and, if necessary, revised, and review should be regular. It is required when a control is not eliminating or minimising the risk so far as reasonably practicable, before a workplace change likely to create a new or different risk the control may not manage, when a new hazard or risk is identified, when consultation results indicate a review is needed, or when an HSR who reasonably believes one of these has occurred requests a review. Reports, complaints including informal ones, and grievances may reveal new hazards and should trigger a review of whether controls and response procedures worked. Review methods include inspection, consultation and analysing records and data, and workers and HSRs must be consulted. The reviewer should have the authority and resources to do it thoroughly and recommend changes. If effectiveness is in doubt, go back through the risk management steps.
