These periods are legal maximums. After changes in the workplace, a work accident or an occupational disease, the risk assessment and emergency plan must be renewed without waiting for the deadline. Equipment inspection intervals may vary by equipment type.
When does each document need renewing?
Most OHS documents have a legal “expiry date” that depends on the hazard class. The easiest way to stay on schedule is to track the last issue date of every document in a single list. The tool above does this calculation for you.
Remember: these periods are maximums. The risk assessment and emergency plan must be updated without waiting for the deadline after events such as relocation, new machinery or chemicals, a change in production methods, a work accident, an occupational disease or a near miss.
For details, see our risk assessment, emergency plan and periodic inspection pages.

Frequently asked questions
When should first aid refresher training be taken?
A first aider certificate is valid for 3 years. Under the amendment of 27 December 2025, refresher training must be taken within the 3 months before the certificate expires. We recommend setting this date in your calendar 3 months before expiry.
Why do equipment inspection dates vary by equipment?
Annex III of the Regulation on Health and Safety Requirements for the Use of Work Equipment (revised on 23 December 2025) sets the maximum intervals: at most 1 year for most equipment and 6 months for scaffolding. If a standard or the manufacturer’s instructions specify a shorter interval, that interval applies.
