Alert others if possible. Go directly to your meeting place and then call the fire department from a neighbor's phone or an alarm box. Every member of your household should know how to call the fire department. Crawl low under smoke. Roll, don't jump out of bed.
Smoke contains deadly gases, and heat rises.
If you encounter smoke when using your primary exit, use you alternative escape route. If you must exit through smoke, crawl on you hands and knees, keeping your head as close to the floor as possible. Once you're outside your home, don't go back for any reason. If people are trapped, the firefighters have the best chance of rescuing them. The heat and smoke of a fire are overpowering.
