Home Smoke Detector Disposal – How To

Photo of improper smoke detector disposal.

Surprisingly, we were hard pressed to find federal regulations or programs for recycling smoke detectors. We couldn’t even find a smoke detector disposal site at Lowes or Home Depot. Fortunately, a few agencies have come up with some helpful guidelines to show you how to dispose of smoke detectors properly.

Do not throw your smoke detector in the trash.

Smoke detectors contain a number of elements and materials that are not suitable for landfills. The following guidelines may be followed when disposing other types of electronic equipment as well. In the interest of preserving our planet, caution should be taken upon disposing of smoke detectors for the following reasons:

Some Detectors Contain Radioactive Materials

Ionization smoke detectors use a small amount of radioactive material in the sensor called Americium 241. While the amount used in most newer ionization smoke alarms is minute and not harmful to humans, it has a very long half life. In fact, chances are when the time comes to replace your ionization smoke alarm, even one with a 10 year battery will have the same the amount of radioactive material as when you bought it.

Pyrotronics Ionization Smoke Detector

Pyrotronics Inc F3 / 5A Ionization Smoke Detector With Base Mount Fire – These outdated units contain more radioactive material than their modern counterparts.

Some older and uncommon high voltage ionization detectors that are typically hardwired and exist in commercial buildings may contain a higher amount of radioactive material and need to be handled differently. Since they were phased out over 20 years ago, it is unlikely that you would encounter this. Click here to view a publication by the Federal Emergency Management Agency which can guide you on how to identify one of these older high voltage ionization detectors and properly dispose of it.

Circuit Boards in Smoke Alarms Are Bad for Landfills

Nearly all smoke detectors, photoelectric or ionization models contain circuit boards which are very bad for landfills. Circuit boards contain lead among other toxins that can leach into the ground and eventually our water supply.

Alkaline and Lithium Batteries

Some detectors contain removable alkaline batteries, just like the ones you would use in your remote control. Furthermore, 10 year sealed battery smoke alarms are as stated, sealed—thus making battery removal impossible. Batteries, alkaline or lithium do not belong in landfills.

Hazardous Waste Drop-Off Sites

You may be able to find local hazardous waste programs for smoke detector disposal. Finding one could be as simple as Googleing “your city + hazardous waste”. While you’re there you can also get rid of your old batteries, medications, chemical cleaners and other electronic equipment. They know how to dispose of smoke detectors and you can drop it off with assurance that the radioactive material contained in an ionization smoke detector is handled properly.

For Radioactive Smoke Detector Disposal – Return it to the Manufacturer

For americium smoke detector disposal or other highly radioactive smoke detector disposal your best bet is to return it to the manufacturer. Albeit, a pain in the butt, this is also the best method of carbon monoxide detector disposal, photoelectric and ionization smoke alarms (all others). First alert disposal address can be found below as well as other manufacturers and their respective shipping address to return old smoke detectors.
