Each member of the family should understand the importance of crawling low under smoke. Smoke and heat rise so the best place to find fresher, cooler air is near the floor. When a person is caught in a building filled with smoke, they should drop on hands and knees and crawl to the nearest exit. Test all closed doors before opening them. Feel the back of the door. If it is hot, don’t open it. Turn and go to the second route of exit. If the door is not hot, open slowly but be prepared to slam it closed again if there are flames.
Practice what to do if you become trapped. Since doors hold back smoke and firefighters are adept at rescue, the chances of survival are excellent. Close doors between you and the smoke. Stuff the cracks and cover vents to keep smoke out. If there’s a phone, call in your exact location to the fire department even if they are on the scene. Wait at the window and signal with a sheet or flashlight or something visible.
