Next tonight our real answers team is back. With the weather getting colder across america, more families are turning up the heat at night and that means more house fires, 1,000 every day. Abc's byron pitts shows us how to make sure that every member of the family gets out alive. Reporter: Six months ago a neighbor's house went up in flames. SO the DeCampo family knew they needed a plan. That's why today 8-year-old eli knows it like his abcs. If we're in bed sleeping and the smoke alarm goes off, we go down stairs and see if we can get out the front door. Reporter: It's his 4-year-old sister lila who worries parents ann and ray. Sometimes the smoke alarm goes off when I'm cooking and she refuses to get out of bed. Reporter: With the help of the fire department, we put this family to the test. Tip one, smoke detectors, the more the better. the DeCampos had one in the kitchen, the basement, every bedroom. But the fire department installed another in the bedroom hall way. Smoke rises. Before it hits the room it will hit the hall way. Reporter: Tip two, practice in real time. We put cameras in the kids' bedroom and hall way and waited for them to fall asleep. Refighters added theatrical smoke. It's harmless. He's getting up. He's getting low under the smoke. Take it easy. He did very good. She's sound asleep. Are you all right? Are you okay? Yes. Good job. Reporter: But where is lila. She needs to wake up. Reporter: Minutes tick by, the alarm doesn't stop. Lila never moves. I can't believe she's still asleep. Reporter: Firefighters tell us young children tend not to wake up so you need to plan for that. Authorities say children respond more redly to a parent's voice. Tip three, record a personal fire alarm warning. In a real blaze this bedroom could have gone up in flames in 45 seconds. At the fire department training center we suit up. Tip four, stay low. Standing in a room filling with smoke, the reasons to get low become obvious quickly. One, it's easier to see as the toxic smoke rises to the ceiling. The number one cause of death in a house fire is asphyxiation. Reporter: Even in their protective gear, firefighters stay low. It can be probably 400 degrees down here. If you go up two or three feet it could be 1500 degrees. Reporter: Once it's engulfed in,flames bang ketd in smoke your home becomes a trap, everything inside a river of fuel. There is no time fo waste. If we can get you out 30 seconds earlier it may be enough to save your life. Reporter: Keeping your family safe. It's possible in a fire if you have a plan.
