Cold alert: open windows risk flooding on campus

As winter tightens its grip on the campus, we’re navigating an icy challenge—freezing pipes and radiators causing unwelcome floods.

But why is it happening and how we can collectively minimize the risks? 

The cold truth unveiled: behind the freeze

When indoor flooding happens in winter, open windows and doors are often the culprits.  

When outdoor temperatures drastically drop, the heating systems in buildings attempt to maintain optimal indoor temperatures. In response, individuals might feel too hot and decide to prop open a window or door to stay comfortable.  

However, because water expands when it freezes, what initially seems like a harmless practice can result in a broken pipe! This can lead to leaking, flooding, and even costly property damage when temperatures return to normal. 

The urgency: safety matters

Fire sprinklers are also susceptible to freezing.  

When sprinkler pipes freeze, they can also burst and cause a flood; more importantly, frozen pipes can cause fire prevention equipment to malfunction, putting everyone’s safety at risk.  

What you can do to prevent it

1. Most importantly, report any temperature irregularities immediately!  

If you notice spaces that are too hot or too cold, submit a service request to notify building operators so that they can address the issue.  Emergencies—such as temperature issues that affect sensitive research facilities, animal facilities, or daycare centres—should be reported to 416-978-3000 immediately. This will help to ensure the safety of our community and research operations.  

2. It’s best practice to keep windows and doors closed, especially during cold weather.

If a window must be opened, ensure it is closed shortly afterwards—and take care to firmly shut exterior doors when entering or leaving a space. 

3. Avoid using door automation when possible.

Unless necessary for accessibility reasons, we recommend avoiding the use of automated doors during periods of extreme cold.

In the face of winter’s tests, it’s essential for us to collectively remain vigilant. Taking proactive measures can ensure our safety while protecting our historical campus and world-class research.
