SafeZone - our free safety app
Download SafeZone for instant alerts during emergencies, such as cyber attacks, campus evacuations, and other critical incidents.
Why download SafeZone?
Whilst the app has multiple functions, one of its most critical roles is to deliver immediate mass communications during major incidents. Its ability to send immediate notifications, independently of the campus network, means we can alert you quickly and directly during emergencies such as cyber attacks, campus evacuations and other critical incidents.
SafeZone is also the easiest way to contact Campus Safety & Security for emergencies, urgent assistance, or to report incidents.
To get the maximum benefit from using the app, read SafeZone’s FAQ on recommended settings.
Coverage areas
SafeZone covers our main campus, residences and the Advanced Manufacturing Group (AMG) site. You can view coverage maps via PDF, or directly in the app by selecting 'Regions' or the map icon.
Outside these areas, SafeZone connects to local emergency services (999 equivalent) worldwide. To communicate directly with security teams when visiting other universities that use SafeZone, you can join the SafeZone Alliance.
How SafeZone works

- Push notifications
When it would be used: Immediate alerts for major campus incidents such as closures, extreme weather, security threats, and terrorist attacks.
Benefit: It’s our fastest, most reliable way to reach you in emergencies. SMS can take 15-20 minutes (and relies on updated personal mobile numbers in MUSE), and emails can take over an hour to reach everyone.
How it works: In an emergency or major event, SafeZone can send instant push notifications containing information, instructions, or links to websites for further details.
What else do you need to know: During phone or email server overload, push notifications are the only guaranteed instant alerts. (Think sending texts on New Year's Eve in a busy city).
Tip: Ensure your mobile number is always updated in your staff or student record. Students can update via the Student Hub's All Services link, and staff via communication preferences in their myJob/myTeam/e-Recruitment personal profile on MUSE.
- First Aid, Help and Emergency buttons
When to use: For minor medical or mental health needs, use the green First Aid button. For immediate threats, use the red Emergency button. For non-urgent security help, use the blue Help button.
Benefit: The buttons instantly connect you with Campus Safety & Security and share your location. Outside our coverage areas, you will be prompted to contact local emergency services.
How it works: Press a button (First Aid, Help, or Emergency) and you'll get 5 seconds to cancel (for accidental presses). If not cancelled, your location is shared with Campus Safety & Security. In critical emergencies, tap the button five times to bypass the timer.
What else do you need to know: Read more about where SafeZone works.
- Check-in
When to use: Working alone or out-of-hours on campus.
Benefit: Provides reassurance that your location is known to Campus Safety & Security.
How it works: Checking in (within our coverage areas) shares your location with Campus Safety & Security, who will only contact you if there's a safety issue related to the building you’re in.
What else do you need to know: Only Campus Safety & Security sees your location when you check in. Location sharing ends when you check out or leave our coverage area.
- Check-in timer
When to use it: Working alone or out-of-hours with higher risks, like lab experiments or walking alone in the dark.
Benefit: Ensures Campus Safety & Security checks your location if you don’t stop the timer, even if your phone stops working.
How it works: Set a timer with location and risk notes. If it expires, Campus Safety & Security is notified and will perform a safety check if you don't respond.
What else do you need to know: Only Campus Safety & Security sees your location and details. Outside our coverage area, they may notify police. Learn more about the check-in timer.
- See it? Say it!
When to use: Reporting non-urgent campus incidents like damage, theft, harassment, or suspicious activity.
Benefit: It's the quickest, most convenient way to report to Campus Safety & Security, saving time over calls and emails, and allows for anonymous reporting.
How it works: Report anonymously, share location, add photos, and notes directly to Campus Safety & Security.
What else do you need to know: Find details on incident reporting.
