The alarm sounded simultaneously in the building and at the fire station, as well as at our security office. And I have to say, we're very proud of the way the students reacted. We do drills a lot, we do fire safety constantly and we're reinforcing that all the time. They did a really good job to get out of the building, to get themselves together and to look out for each other. All of the systems worked the way they should have and nobody was hurt.
