The Institute for Work & Health (IWH), in collaboration with Workplace Safety North, piloted a workplace questionnaire to measure perceptions of practices related to the internal responsibility system in Ontario's mining sector. In a February 2017 presentation, IWH President and Senior Scientist Dr. Cameron Mustard presented an overview of the development of the instrument, called the Internal Responsibility System Climate Assessment and Audit Tool (IRS CAAT), and the psychometric analysis of that instrument at four mining operations.
