Evacuation or shelter in-situ
In some circumstances, taking shelter in your own home/office (shelter in-situ), closing windows and turning off air conditioning etc. may be a safe option. Alternatively, evacuation from your home/office may be necessary.
The decision to shelter in-situ or to evacuate will be made by the agencies responding to the emergency and will be based on a risk assessment of the nature of the emergency and the environment at the time.
You will be informed of what you need to do via a number of channels that may include local radio, social media, public address systems or having someone knocking on your door.
