Health and safety training
IWH research on occupational health and safety (OHS) training focuses on its effectiveness—from the effectiveness of delivery methods and contents to the effectiveness of training programs overall. OHS training, mandated by workplace health and safety laws in jurisdictions across Canada and beyond, is considered an important part of managing workplace hazards and risks. Such training may involve instruction on identifying occupational risks and how to control them, learning about safe workplace practices and how to properly use personal protective equipment.
