Leading OHS indicators
Occupational health and safety (OHS) leading indicators are performance measures that help predict injuries and illnesses, allowing workplaces and system partners to gauge an organization’s health and safety climate, safety culture and OHS performance before injuries and illnesses occur. Their opposite is lagging indicators such as injury and claims rates, which measure performance based on injuries and illnesses that have already occurred. IWH research focuses on finding and validating the measures that will accurately gauge the likelihood of an organization’s future OHS performance, as well as the best way to use leading indicators to prevent future work-related injuries, illnesses and deaths.

SCSA uses survey tool to help companies prevent incidents before they happen
An innovative new survey tool is being used by the Saskatchewan Construction Safety Association (SCSA) to help companies identify hazards and prompt them to take steps to reduce injury risks, reports Grant Cameron. The tool was developed by the SCSA in collaboration with EHS Analytics, a Calgary-based company that specializes in health and safety data, research and machine learning. The survey is an eight-item questionnaire developed by the Institute for Work & Health (IWH) and Ontario’s prevention systems partners to assess values and beliefs around a company’s workplace culture. Data collected can be used to help identify where improvements need to be made.
