Building Safety The following is a set of guidelines to be followed to ensure a safe and secure environment: Ensure that all exterior doors are locked when you enter and leave the building after hours. Building hours are as follows: Monday to Thursday: 7:30am to 8:00pm; Friday: 7:30am to 6:00pm Do not leave a door propped open. If you find one, close it. Report all unlocked doors of faulting locking mechanism to the UofT Campus Police after hours. You can reach them at 416-978-2323. Do not let anyone you do not recognize as working in EEB into the building with you after hours. Report any suspicious looking/acting individuals roaming the building to the EEB administrative office, or call UofT Campus Police directly. Whenever possible, lock the door to your lab, group room, or office when you leave. If your door is equipped with a dead bolt, engage it using the door key when you leave. Do not leave valuables, including laptops, lying around on your desk or lab bench. Keep them out of sight. Lock them away before you leave. Keep a record of serial numbers for computers and other valuable electronic equipment. Make sure your data is backed up elsewhere. Immediately report ALL lost or stolen door keys to EEB reception by email, in person, or by calling 416-978-8514. Do not, under any circumstance, lend your door keys to anyone, even if for a short period of time.
