Control measures must be maintained so they remain fit for purpose, suitable for the nature and duration of work, and installed, set up and used correctly (r 37), and reviewed and if necessary revised (r 38) so that, so far as reasonably practicable, the work environment is without risk. Review is needed when a control does not control the risk so far as reasonably practicable, before a change likely to give rise to a new or different risk, when a new or relevant hazard or risk is identified, when consultation shows a review is needed, or when a health and safety representative reasonably believes a circumstance affects their work group and the control has not been adequately reviewed. Common review methods are workplace inspection, consultation, testing and analysis of records, and workers and HSRs must be consulted.
