How can you tell if your thermometer or thermostat contains mercury?
 |
 |
| Mercury thermometers have SILVER, METALLIC GREY or BLACK filling in their bulbs. Any other color filling indicates it is a non-mercury thermometer and it may be thrown in the trash at the end of its life. | Mercury thermostats have dials or levers that you need to manually adjust. If you take their faceplate off and see one or more sealed glass capsules containing a silver substance, you have a mercury thermostat. |
If you have mercury thermometers gather them along with other household toxics and make an appointment for OCRRA's free Household Hazardous Waste drop off program.
If you have mercury thermostats, find a list of locations that accept mercury THERMOSTATS in the community.
If you have a broken thermometer or other mercury containing device, follow these steps:
- Place all parts in an airtight container and seal it.
- Make an appointment for OCRRA’s Household Hazardous Waste Drop Off Program.
- Maximize your appointment by bringing other household toxics to your appointment drop off too.
