In case of fire, don't stop for anything. Do not try to rescue possessions or pets. Go directly to your meeting place, and then call the fire department from a neighbor's phone. Every member of your household should know how to call the fire department. Crawl low under smoke.
Smoke contains deadly gases, and heat rises.
Cleaner air will be near the floor. If you encounter smoke using your primary exit, use your alternate escape plan. Once you are out of your home don't go back for any reason. If people are trapped, the fire fighters have the best chance of rescuing them. The heat and smoke of a fire are overpowering.
