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.

New funding announced for worker safety in mining and forestry

In what was described as a strategic, provincewide collaboration, the WSIB has partnered with Workplace Safety North (WSN) and the Institute for Work and Health (IWH) to lead a proactive campaign aimed at enhancing hygiene monitoring practices and reducing exposure to harmful workplace hazards. The initiative, spearheaded by WSN, is to focus on high-risk sectors such as mining and forestry, where workers continue to face some of the highest rates of occupational illness fatalities in Ontario. WSN has developed a suite of specialized training materials and will work directly with employers and workers through hands-on coaching and real-time use of hygiene monitoring equipment. The IWH will support the initiative by applying its expertise in health and safety research to assess the effectiveness of the training programs and their impact on improving worker safety.
