Take action to reduce or eliminate health and safety risks in your workplace with the new HazardAssess app, a collaboration between CCOHS and OHCOW. HazardAssess is available free of charge on iOS and Android.

Audit your health and safety conditions, identify concerns, and report them for action and follow-up.


StressAssess is a free, evidence-based online survey tool designed to assist workplaces in identifying psychosocial hazards that can lead to stress and mental injury, providing suggestions and pathways to address them, thus preventing harm. It is simple to use, fosters a team approach, and includes a Wizard to support preparation, implementation and subsequent problem solving. StressAssess is particularly timely given the recognition of Chronic Mental Stress as compensable in Ontario beginning January 1, 2018. Plus reducing stress and promoting Workplace Mental Health is good business on many levels.


Indoor air quality issues at work can be caused or aggravated by a number of factors. The interrelationships between these factors can be quite complex. By answering questions about your environment, symptoms, workplace stress levels, and allergies, you can help identify issues which may be related to the air quality in your workplace. This app will look for links and provide you with some ideas to help address these air quality issues.  Plus you can share the results to raise awareness and start a discussion about IAQ solutions in your workplace.

AirAssess consists of three scientifically recognized questionnaires on the indoor environment (air quality), job strain (stress), and asthma symptom screening. The app, and the tips provided, are based on the work OHCOW, who have used these surveys in a large number of workplaces over the past several years.  It is brought to you through the technical assistance and support of our partners at the Canadian Centre for Occupational Health and Safety (CCOHS).  


This app is the result of a valuable and productive professional collaboration: combining the clinical expertise and ergonomic content of the Occupational Health Clinic for Ontario Workers (OHCOW) with the technological knowledge and communication skills of the Canadian Centre for Occupational Health and Safety (CCOHS).
