Smoke Detectors

Two common types of smoke detectors are ionization detectors and photoelectric detectors. Ionization-type smoke detectors contain a small amount of radioactive material. For these detectors, it is required by law to have a warning label, usually found on the “back” of the detector, or the part facing the mounting base that is connected to the wall. Photoelectric-type smoke detectors do not contain radioactive material.

Household Ionization Smoke Detectors

• Detector Manufacturer: mail the detector to the manufacturer. Manufacturer name should be listed on the back of the detector, in the instruction booklet or warranty.
• Household Chemical Collections: Accepts household ionization smoke detectors for hazardous waste disposal from Berrien County residents. 

Detectors with No Radioactive Materials

• Remove and recycle the battery. See Battery recycling options. The detector itself can be disposed of in household trash.

Note: Industrial smoke detectors are not accepted at the County recycling events and should be disposed properly through the manufacturer.
