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.
