When fire occurs in your home, your chances for survival are two times better when smoke detectors are present than when they are not. Early warning increases your chances for survival and allows the fire department to save more of your property. In support of smoke detector effectiveness, many cities and states have laws requiring the installation of smoke detectors in dwellings. Check with your local fire department or State Fire Marshal for further information.
Time is crucial.
Most fatal fires occur between midnight and 8 a.m. Many fire victims die in their sleep from breathing smoke and toxic fire gases. Develop and Practice a Home Escape Plan. Electric smoke detectors should be connected to a lighting circuit with no intervening switches. For this, you may need an electrician.
