Process audits help officers to meet their third due diligence obligation, ensuring the processes you have made available are being used to eliminate or minimise risks of harm. They are designed to confirm the elements of your health and safety management system are consistently used across the entire business. An example is your contractor management system that should be effective in enabling the PCBU to confirm all its workers are competent to work safely, or how well your Safety in Design processes are meeting your duties as an upstream PCBU.
It is good practice to undertake periodic random audits, to give you confidence that your health and safety systems and processes are embedded throughout your organisation.
Maybe you can confirm you have a health and safety management system, but do you know if it’s being used, consistently?
