The Science of Safety Training: What Works and What Doesn't

The Question

Safety training is one of the largest recurring investments in workplace safety. It is also one of the least scrutinised. Most organisations default to classroom lectures, e-learning modules, or toolbox talks — methods chosen for scalability and cost rather than effectiveness. If you are responsible for safety training spend, you need to know: which training methods actually reduce injuries? Is there a point at which more training stops helping? And why does so much safety training fail to change behaviour beyond the training room?

Key Findings

The Bottom Line

The evidence on safety training effectiveness reveals an uncomfortable gap between common practice and what actually works. Across 123 studies and over 20,000 participants, the research is clear: as training methods become more engaging and participatory, safety outcomes improve. Behavioural modelling and hands-on practice produce the largest effects. Lectures, pamphlets, and passive e-learning — the methods most organisations rely on — are the least effective. And mandatory training consistently underperforms voluntary training.
