Smoke Detectors Question?




kasmira25


I just moved into a whole house and have noticed that there is one non working old as dirt smoke detector in the kitchen and non anywhere else in the house.

How many smoke detectors do i need?
I live in upstate NY
The house has a full unfinished basement, first floor,second floor with 4 bedrooms and bathroom, unfinished attic.
Gas heat and stove- so do i need a carbon monoxide detector?
I have two small children
The house is not new, its an older victorian

Any info would be helpful as to the amount and placement!! Thank you!



Answer
Not sure what the laws are regarding them, but I will give you best practices.

There should be at least one smoke detector and one carbon monoxide detector on each level of the home.

Each bedroom should have it's own smoke detector, preferably near the door to catch any smoke entering from the hallway.

Don't put a smoke detector in the kitchen due to nuisance alarms, but it's a good idea to have one nearby.

So I would recommend 8 smoke alarms and 3 CO detectors. If you want you can substitute 3 CO/smoke combo detectors.

Put one in each bedroom, one in the main hall on the second floor, two on the main floor, and one or two in the basement depending how big it is.

Is carbon monoxide heavier than air?

Answer
NO. It has nearly the same density as air. (Note the first answer confuses carbon dioxide with carbon monoxide.)

If you're concerned about where to place your CO detector, location doesn't matter. In a room, all gases will tend to mix due to convection, it would take a perfectly still room under controlled circumstances to "layer" different gases. Most alarms are placed high because when there is a fire, the hot gases tend to rise. One of the most common sources of CO is some kind of combustion appliance e.g. heater so again it tends to be hotter and rise. The key points are to have at least one on every floor, to place them in the center of the room so they can measure the general level of CO, and for extra safety to have one 15 feet away from any potential CO sources like a gas burning appliance (not right next to it!).

For more info on placement of CO detectors, pls see these URLs which I got by searching "where place CO detector", they come from authoritative sources such as fire safety sites.
