Illness/injury prevention
IWH has a long history of conducting research to provide practical guidance to employers, workers, OHS professionals and regulators about what works and what doesn’t in injury or illness prevention. This research targets the injury and illness prevention practices of workplaces, as well as the programs developed by governments, health and safety associations and others to support and motivate workplaces to adopt effective practices.

Occupational health and safety performance in Ontario's unionized construction sector
A previous Institute study found that, during the period 2006-2012, unionized contractors in Ontario's industrial, commercial and institutional sector had higher no-lost-time claim rates and lower lost-time claim rates than their non-unionized counterparts, suggesting unionized contractors may do better at encouraging injury reporting and reducing injury risk. A new IWH study is replicating the methods of this previous study for the time period 2012-2017.

Research on silica exposure controls finds PPE comes at a cost
Research estimating cancers averted and intervention costs of two silica control measures offers an important new perspective on the control of occupational cancers. Among the compelling findings, researchers concluded that personal protective equipment (PPE) is not the most cost-effective method of protecting workers from silica exposures, calling into question the common practice of providing PPE to workers exposed to hazardous materials.
