What is Invacuation

Invacuation is the opposite to evacuation, i.e. refuge is sought inside a building during an emergency. Invacuation may be required when there is an environmental hazard, (such as a smoke cloud or suspected chemical leak), or a security related incident.

If invacuation is necessary a warbling siren (peow-peow) will be sounded for 30 seconds. This siren is very different from the fire alarm and should therefore be instantly recognisable.

Within a few minutes of the siren sounding emergency messages will appear on the computer screens around the Campus giving the reason for the siren and certain instructions to follow. [The computer system only searches for these emergency messages on a 2 minute cycle].

When you hear the siren you should take the following action:

  • If you are in the open air, proceed to the nearest building and go inside.

  • Take immediate cover away from windows and doors (which should remain closed and locked if instructed dependent on the nature of the emergency)

  • Seek a volunteer(s) who can monitor the main doors from a safe location to allow entry to other known members of staff or students to take cover

  • Remain in the secure area until instructions are received from Security staff (First Responders) or the Emergency Services or as directed on the computer screen emergency messages

  • Make sure you have access to a computer screen

  • Keep computers and TV screens switched on for further information.

  • Tell others about the computer message if it is obvious that they don't have access

  • Only leave a building when directed to do so by Security staff (First Responders) or the Emergency Services or as directed by the computer screen emergency messages

  • Sheltering inside can be an effective way to protect yourself in some emergency situations but you should only do so if directed by a member of the emergency services or by activation of the invacuation alarm.

  • Once the emergency is over a second steady tone siren will be sounded to demonstrate the ‘All Clear’; this will be accompanied by an emergency message giving information about the all clear.
