Worries of a potentially dangerous chemical leaking at the University of Alberta caused officials to issue its emergency broadcast system as a warning. The system sent out text messages, e-mails, and phone calls to warn of a potential danger on campus.

Fire crews were called to the university Tuesday morning on a report of an unconscious person at a residence in HUB Mall. The caller also reported to emergency officials of a possible chemical on scene.

Shortly after, students and staff began receiving messages about a possible emergency on campus. Students sign on for the emergency broadcast system at registration by providing their cellphone number.

"It was the first time I received this message. I was a bit confused about whether I should trust it or not. Then it kept coming four times and I realized something must be going on," said student Nazlee Sharmain.

The system has been in place for several months, but this is the first time it has been used.

Firefighters determined there was no danger to the public. A deceased person was discovered by crews, but the individual's cause of death is not being released.
