Australia Model Code of Practice: Managing Risks of Hazardous Chemicals in the Workplace 5.2: 5.2 Review chemical risk controls on defined triggers and at least every five years (rr 38 and 352)

Controls must be reviewed and revised as necessary to maintain a work environment without risks (r 38; r 352). Reviews are required when a control does not control the risk so far as reasonably practicable; before a change likely to create a new or different risk; when a new relevant hazard or risk is identified; when consultation shows a review is needed; when an HSR who reasonably believes one of these has occurred asks for a review; when an SDS or the register changes; when a health monitoring report shows elevated exposure, possible disease or injury, or a recommendation for remedial measures including whether the worker can continue the work; when atmospheric monitoring shows the exposure standard is exceeded; and at least once every five years. A change includes a change to the workplace or work environment and to a system of work, process or procedure. Review by inspection, consultation, testing and analysis of records, consulting workers and HSRs, and questions such as whether controls work, introduced new problems, procedures are followed, training succeeded and incidents are falling. If problems are found, return through the risk management steps.
