Do smoke detectors really prevent fires?
When I started in business some times I would see a photograph in the Chronicle News Paper that showed ther result of a fire. There was nothing left but the foundation.
Smoke detectors do a really good job of saving lives. here are two kinds of smoke detectors. Ionization and light sensing. Either one will do a good job.
Smoke detectors detect smoke. Smoke is hot so it rises to the ceiling. For this reason smoke detectors give the earliest warning when located on the ceiling rather than lower down on the wall. I recommend a smoke detector be placed on the ceiling in the area above the door because that walk way space is almost always clear enough to place the ladder when it is time for the yearly battery check. The electrical code recommends the smoke detector be at least 12 inches from the wall because when there's a fire the smoke circles around and does not go in to the corners. If you've ever gone into a house after a fire you will notice the corners of the rooms are still soot free.
The smoke detector followed by the fire department does a good job of stopping fires. However there still a big problem. Everyone has to move out due to fire damage in one room and smoke damage in all the other rooms. Another problem is during a fire the air temperature usually gets hotter than 60 degrees centigrade which is the temperature which Old Knob & Tube is approved for use there for the old wiring has to be ripped out replaced with new wire.
You should have a smoke detector in each bedroom and the hallway. The hallway is your escape route. I also recommend a smoke detector in your basement and another in your garage. Do not place a smoke detector in the kitchen. You will have false alarms.
Smoke detectors are placed in the bedroom because when people are asleep a small fire will not wake them in time. The smoke detector in the hallway will alert them not to go out in to the hall if there's a fire outside the door.
