Smoke & Fire Alarms/Detectors
Smoke and fire alarms/detectors are NOT ACCEPTED at SWALCO collection programs (Electronic Collections or Household Chemical Waste Collections). As you probably know, there are numerous brands and types of smoke detectors available, selection can be tricky. Additionally, some smoke detectors have a small amount of the radioactive material Americium-241, leaving residents uncertain of how to dispose of the detectors in a responsible manner. If a smoke detector contains radioactive material, it is required by law to have a warning label on the body of the smoke detector. The label is usually located at the “top” of the detector, facing the mounting base that attaches to the ceiling or wall. So, before wandering the isles of the hardware store, please take a moment or two to review possible detector selections and end-of-life disposal options. After all, we are all responsible for what ends up in our landfills.
Listed below are the types and functionality of each plus information about possible hazards.
Ionization Smoke Alarms
Ionization smoke detectors are designed to detect quick, flaring fires. These detectors contain a small amount of the man-made, radioactive material Americium-241. When smoke enters the ionization chamber of this type of smoke alarm, it disrupts the flow of particles coming from the radioactive material, causing the alarm to activate. The quantity of Americium-241 contained in the ionization chamber of the detector is small and emits minimal radiation, so it is considered safe for human exposure (unless the device is tampered with - Don't do that!). These types SHOULD NOT be disposed of through the regular trash. Please check the manufacturer’s website for mail-back programs/disposal options or information included in the device packaging (phone number and/or address).
Photoelectric Smoke Alarms
Photoelectric smoke detectors function best for detecting smoky, smoldering fires. Unlike ionization smoke alarms, photoelectric smoke detectors do not contain any radioactive material but rather rely on an electric current to produce a beam of light. When the light beam is disrupted by smoke, the smoke alarm is set off. As long as there in no radioactive symbol or warning label. This type of CAN be disposed of through the regular trash. PLEASE BE SURE TO INSPECT the device thoroughly before making your final decision regarding disposal.
Dual-Sensor Smoke Alarms
Dual-sensor smoke alarms combine ionization and photoelectric technology in one detector. These types SHOULD NOT be disposed of through the regular trash. Please check the manufacturer’s website for mail-back programs/disposal options or information included in the device packaging (phone number and/or address).
Combination Smoke/CO Alarms
Combination Smoke and Carbon Monoxide alarms can detect both smoke and carbon monoxide. These types SHOULD NOT be disposed of through the regular trash. Please check the manufacturer’s website for mail-back programs/disposal options or information included in the device packaging (phone number and/or address).
