I took this picture outside my friend's apartment in London. I just found it interesting that they used a honk as fire alarm. I wonder what would happen in case of a real fire. Would you still have time to read the pamphlet behind it and hold the air honk? I guess when you see smoking or a fire, you would be freaking out and trying to run down the stairs as soon as possible, rather than trying to locate the honk and read the notice sheet behind it.
Bravo! I guess that's the British way of fire safety!
