At the Luton airport they have these big "mass casualty event" supply boxes on the walls. Presumably full of supplies to provide efficient first aid after such an event on the spot.

As I was writing this comment I learned that they were inspired by a bombing which happened in Brussels: https://www.shponline.co.uk/fire-safety-and-emergency/mascal...

One of those things you hope will never need to be used. But if it is ever needed it will be very handy.
