A vertical evacuation is also known as searching for a safe environment. This could mean that you need to look for this environment on a higher or lower location. A vertical evacuation usually only applies to buildings with multiple floors. The vertical evacuation will, in this case, take place across stairs. ‘Searching for a safe environment on a higher location’ could occur when an area is plagued by a flood. This is also often a “cheaper way” to evacuate in contrast to a pre-emptive evacuation of a complete area.
When immobile persons are involved in a vertical evacuation, it is advisable that organizations are equipped with the right evacuation equipment which can speed up the evacuation. This can ease the evacuation process for those in need and for the aid worker.
