The worst danger is a house on fire when people are asleep. Always be ready to leave through a window into the garden by making sure you can open it if necessary. If you should be on holiday in a tall building or hotel, make sure you know where the fire escape（太平梯） is . When you can’t find any way out, try to find pieces of cloth and make a rope to get out of a window to safety. If you smell burning in your home, get out right away. If you can’t breathe properly because of smoke on your way out, crawl（爬行） on your hands and knees because smoke rises and the air will be cleaner near the floor. Smoke is a killer and more people have died from breathing it in than actually being burnt.
Fire in a cinema, hall or public place often means people pushing to reach a door. Keep your head up with arms up in front of your chest（胸）.This protects your chest and gives you the best chance to breathe. Above all, don’t get frightened!
