Evacuation
From Wikipedia, the free encyclopedia.
Evacuation can have several meanings:
- In wilderness first aid, evacuation is the transport of a seriously injured person out of the wilderness to the nearest point an ambulance can reach to take them to the hospital, or to the nearest emergency room. It is first necessary to stabilize the patient prior to moving them to avoid causing further injury. Evacuation may involve carrying the victim some distance on improvised stretchers, a travois or other improvised carrying gear. See also Casualty movement.
- In bomb threats, it is usual to evacuate an area by clearing all people out and securing the perimeter, usually until the bomb squad conclude that there is no bomb, remove it, detonate it safely or dismantle it.

- At the start of World War II, around 3.75 million British civilians were temporarily relocated out of the major urban centres, to minimise casualties. See Evacuations of civilians in Britain during World War II for more details.
