If you are trapped, close all doors between you and the fire. Stuff the cracks around the doors to keep out smoke. Wait at a window and signal for help with a light-colored cloth or a flashlight. Every member of your household needs to know what number to call for help in an emergency. Crawl low under smoke.
Smoke contains deadly gases, and heat rises.
During a fire, cleaner air will be near the floor. If you encounter smoke when using your primary exit, use an alternate escape route. Don't go back inside for any reason. If people or pets are trapped, the firefighters have the best chance of rescuing them. The heat and smoke of a fire are overpowering.
