"Know your exits. If you're at a concert or bar or theatre or anywhere like that take a second when you arrive to note the location of the exits. In a fire or other disaster most people will head for the door they came in. If there's going to be a crush, that's where it will be.

If there is smoke then, if possible, get low and stay down until you're out of the building. One or two breaths of smoke can incapacitate you. If you can't get low try and find something - a shirt, a scarf, anything, to tie over your mouth and nose. If you can wet it first so much the better.

And remember once out never ever re-enter a burning building. The odds are that you won't save anyone, you'll just add to the body count. I mean if your kids are in there you're probably going to ignore this and that's understandable, but just know you have very low odds of success without breathing apparatus.

The first of these is hugely important though, so I'm repeating it. Always always know your exits."
