A worker completed safety training two years ago. Since then, their role has changed, the equipment has been upgraded, a new procedure has been introduced and the team has had two near misses.
Is that worker still properly trained?
That is the problem with treating health and safety training as a one-time event. A certificate may show that training happened, but it does not always show that the training is still relevant to the work being done today. This is especially important for higher-risk work, where small changes in process, equipment, environment, or supervision can affect how safely a task is performed.
One-and-done training often creates uncertainty because no one knows when to revisit it. A more practical approach is to define clear triggers for reviewing training.
A useful framework is to review training when there is a change in:
This helps managers make decisions based on real workplace changes rather than relying on memory or waiting until a certificate expires.
The Canadian Centre for Occupational Health and Safety notes that competency in OHS contexts may involve knowledge, training, experience, and awareness of hazards. That means employers should look at training alongside practical experience, supervision, observation, and workplace changes.
Keeping training current does not always mean sending everyone back through the same full course. The right response depends on what changed and how much risk is involved.
For example, a minor procedure update may only require a toolbox talk or supervisor briefing. A new piece of equipment may require formal instruction and a practical demonstration. A serious near miss may require retraining, closer supervision, or a review of whether the original training was effective.
Employers can ask:
What changed? Who is affected? What do they need to know or demonstrate before continuing the work safely?
This keeps refresher training focused, relevant, and easier to apply.
