Expiry Dates on Training Some occupations / tasks have stipulated Code or Regulation type expiry dates. As we know Forklifts = 3 years. For us, we reckon, in our risk environment, our people could do with a refresher, to bring matters back to front of mind, every 2 years. Hasno Regs have 5 years for Certified Handlers. 5 years is fine for us.
In the absence of Code/Regulation it is for you to consider your risk and set your own time limits to ensure your people are trained and safe.
It gets a bit complicated when you have training providers (Such as First Aid) put a two year limit on their training, but if you look at literature, such as the Australian Code they reckon 3 yeas is fine. So in this instance you adhere to the training provider standards
Like most things its situation dependent and you need to make your own call - worksafe won't ping you if you can show you are managing a risk through training. The time limit will, broadly, become irrelevant because if they come to investigate a serious accident there will be more apparent factors/fault that led to the issue.
