You should schedule regular intervals to review how well your safety action plan is working and update it when necessary. In addition, when there is new equipment or procedures, your risk assessment may need to be revised as introducing something new could introduce a new risk. An effective way to do this is to talk to your workers about the possible change/s.
As your safety plan is updated, your hazard reporting procedure should also be reinforced with workers encouraged to report any hazards for which action should be taken immediately.
You should also dedicate time to conduct workplace inspections at regular intervals to enable you to identify hazards that have not been picked up during a normal working day.
In some cases, you may need to bring in a subject matter expert (SME) to assist in setting up a safety system. This could be an independent workplace safety and health professional from a reputable company or it could be a workplace safety and health advisor from your trade association. It is good practice to have an audit of your safety systems done every 2 – 3 years and can assist you to monitor how you are complying with the law.
