Here’s a simple practice for SA I read about for survival. Everytime you check in to a hotel find the staircase exit. Then count how many doors you are away – this comes in handy in the event you have to crawl out of your room with a hallway filled with smoke. Next, look at every fire extinguisher on the way to your room – are they full? Now expand on that every chance you get and repeat every time. Where are all the exits, are the doors chained shut (recent nightclub fire disasters), hall cameras, what side of the building are you on, who doesn’t fit in, etc. Practice everywhere you go.
