Key messages
Reviewing controls should be done regularly and must be done:
- when the control does not work effectively
- when more could reasonably be done to eliminate or minimise risks
- before changes at the workplace that might result in new or different work health and safety (WHS) risks
- when new hazards or risks are identified
- if the results of consultation indicate a review is necessary, or
- if a health and safety representative (HSR) requests a review for one of the reasons stated above, or if they believe your review of control measures was inadequate.
Reports, incidents, complaints (including informal complaints) or grievances from workers may identify new hazards or risks and should trigger a review. These do not have to be raised in a WHS context to be seen as a WHS issue. For example, a worker raising concerns about excessive work hours may indicate that the risk of fatigue is not being managed well in the workplace.
Questions to consider may include:
- Are controls working effectively, without creating new risks?
- Have risks changed or are they different to what you previously assessed?
- Are workers (and their representatives if they have them) actively involved in and consulted on the risk management process?
- Are workers open to raising WHS concerns and reporting problems promptly?
- Are workers trained to identify and report WHS concerns?
- Are there any upcoming changes that might result in a worker being exposed to new or different risks?
- Are new controls available that might better control the risks?
- Have risks been eliminated or minimised as much as they reasonably can be?
If the effectiveness of the controls is in doubt, go back through the risk management steps, review your information and make further decisions about controls in consultation with workers.
