Alerts point to one single source of information

When an alert is sent out, the TMU Safe system will generate an accompanying web page that will act as the single source of information. This page will be hosted by AppArmor (the mass notification system supplier) on their servers. Alerts to your device, email, on the website banner and Twitter will point to this page for all the details we have available for you.

The aim is to get you the information you need to make informed decisions, which means you may receive multiple alerts within the span of a few minutes.

The source of information page include all details about a specific safety alert on campus.

Each time a new alert is sent, a new source of information page will be generated. We encourage you to pay attention to the date and time stamp on the alert so you know when it was sent. 

When the issue is resolved, an “all clear” notification will be sent

TMU Safe alerts provide the latest and most up-to-date information. When an issue has been resolved, we will send an alert stating the issue is all clear.
