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.
