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.

Research Highlights
Evaluating the effectiveness of mandatory working-at-heights training standards
The introduction of a mandatory training standard for construction workers using fall protection equipment is associated with a 19.6 per cent reduction in the incidence rate of lost-time claims due to falls targeted by the intervention. This decline is larger than an overall decline in injuries in the sector during the same time frame. Reductions in incidence rates are also largest among the smallest employers.

Regulated working at heights training works and needed: studies
Two recently released Ontario studies demonstrate why mandatory, standardized working at heights training is so critical to worker well-being. One study undertaken by the Institute for Work & Health (IWH) conducted an evaluation of the impact the province’s working at heights training standard had on workers and their work sites. A second and earlier probe prepared by the Ministry of Labour (MOL) for the Chief Prevention Officer undertook root cause analysis of worker deaths from falls from heights.
