On hearing the fire alarm signal, all persons must leave the building they are in promptly and make their way to the appropriate assembly point (pdf) for that building. Note: in CBG, FAW, NAB, PAN, PEL and SAW there is an additional signal for occupants to prepare to evacuate.
If you hear this signal, you should wait for the full alarm before leaving. People should not attempt to re-enter the building until they have been directed by a member of Security staff that it is safe to do so. For more information please see the Fire Safety web page.
Anyone who has a disability or medical condition (whether temporary or permanent) that could affect their ability to respond to a fire alarm and leave a building using staircases should contact the Fire Safety Officer so that a personal emergency evacuation plan can be developed for them.
