Firefighters are often called upon to speak to school and community groups about the importance of fire safety, particularly fire prevention and detection. Because smoke detectors cut a person's risk of dying in a fire in half, firefighters often provide audiences with information on how to install these protective devices in their homes.    
A smoke detector should be placed on each floor level of a home and outside each sleeping area. A good site for a detector would be a hallway that runs between living spaces and bedrooms.    
Because of the ''dead' air space that might be missed by turbulent hot air bouncing around above a fire, smoke detectors should be installed either on the ceiling at least four inches from the nearest wall, or high on a wall at least four but no further than twelve inches from the ceiling. Detectors should not be mounted near windows, exterior doors, or other places where drafts might direct the smoke away from the unit. Nor should they be placed in kitchens and garages, where cooking and gas fumes are likely to set off false alarms.
