In 2010, WorkSafeNB asked the Institute for Work and Health (IWH) to assess its Internal Responsibility System Questionnaire (IRSQ), a survey tool it had developed to measure safety culture within an organization. As part of its assessment, IWH compared the IRSQ with another previously validated tool designed to measure leading indicators, called the IWH Organizational Performance Metric (IWH-OPM). IWH's findings and recommendations are outlined in this report.
