Indoor Air Quality Update – Wildfire Smoke

Shared on behalf Capital & Facilities and Occupational Health and Safety


As many of you have noticed, wildfire smoke in the community has resulted in a noticeable smoke odor in some areas of the Hospital. We understand this may be concerning and want to provide an update on our indoor air quality monitoring.

The primary health concern associated with wildfire smoke is exposure to fine particulate matter (PM2.5), which can affect respiratory health. To assess indoor air quality, particulate levels (PM2.5 and PM10) were measured throughout the Hospital.

The monitoring results show that both PM2.5 and PM10 levels remain within acceptable ranges, indicating that the concentration of airborne particles associated with wildfire smoke is low inside the facility.

These results demonstrate that the Hospital’s ventilation and filtration systems are effectively reducing airborne particulate matter from the outdoor wildfire smoke. While a smoke odor may still be noticeable indoors, this is likely due to gases and volatile compounds produced by the wildfire that can be detected by smell but are not measured by particulate monitoring equipment.

Although the presence of a smoke odor can be unpleasant, it does not necessarily indicate that harmful levels of smoke particles are present. Based on the monitoring completed, indoor particulate levels remain within acceptable limits, and the Hospital’s air handling systems continue to provide effective filtration.

Our Maintenance team is actively monitoring indoor air quality and testing areas throughout the Hospital on a daily basis to ensure ventilation and filtration systems continue to perform effectively. If you have concerns about the air quality in your work area, please submit a work order so that an assessment can be completed.

We will continue to monitor indoor air quality and outdoor wildfire conditions and will take additional measures if conditions change.

Please note that due to poor external air quality, the outdoor courtyards and terraces are closed until further notice. 

Thank you for your continued dedication to providing safe, high-quality care to our patients and community.

Code Grey – Air Exclusion Policy Refresher

Shared on behalf of Ryan Sears, Director, Capital and Facility Services


As we begin to encounter the effects of wildfire season in our region, it is important that we review and follow our indoor air quality monitoring processes and Code Grey – Air Exclusion policy. 

This wildfire season, Environment Canada has yet to issue a special air quality statement for the Thunder Bay area. However, smoke from active area fires has become noticeable. These fires put particles and gases into the air that can be harmful to human health. When this occurs, people may experience symptoms such as increased coughing, throat irritation, headaches, or shortness of breath. Our Air Exclusion Policy aims to reduce this risk to the internal environment and mitigate or reduce these associated impacts. 

With Ontario’s legislated fire season running from April 1 to October 31 annually, Maintenance monitors internal air quality and will advise leadership accordingly should air quality degrade beyond acceptable thresholds.

On July 10, Thunder Bay Regional Health Sciences Centre (TBRHSC) welcomed a delegation of health care professionals from the Republic of Korea for an educational exchange focused on medical education and clinical training.

The visiting group included faculty members from Inha University College of Medicine, experts from the National Medical Center, and representatives from the Korean Institute of Medical Education and Evaluation. Their visit provided an opportunity to learn more about the innovative approaches to medical education, distributed learning, clinical training environments, simulation-based education, and learner support systems offered at TBRHSC.

The delegation toured several key clinical and educational areas, including the Ibn Sina Simulation Lab, the Physician Lounge, the ICU Regional Critical Care Response Program and Regional Paediatric Response Program. Throughout the visit, team members shared knowledge on how our programs support learners and health care professionals across Northwestern Ontario.

The visit highlights TBRHSC’s ongoing commitment to excellence in education and its role as a leader in training the next generation of health care professionals. International collaborations such as this foster the exchange of ideas, strengthen global partnerships, and contribute to continuous innovation in medical education and patient care.

We were pleased to host our colleagues from Korea and look forward to future opportunities for collaboration and shared learning.
