It is important if you replace your thermostat to check to see if it has mercury before throwing it in the trash. If you see a little oval bulb with a silver liquid inside the bulb you have a thermostat which contains mercury. It is important to properly dispose of this part of your thermostat which contains mercury. Other HVAC controls which contain mercury are boiler controls especially on steam boiler systems. It is improbable that the typical homeowner or business owner will replace this control if it malfunctions but maintenance personnel and HVAC and boiler technicians should be aware of these new laws and the fact that mercury harms the environment so that they properly dispose of any product which contains mercury.

At the end of the usable life of a product which contains mercury the products which contain mercury must be recycled or disposed of in accordance with Local, State, and Federal Regulations so that the mercury in these products do not harm the environment.

Please refer to your individual state laws and regulations to determine specific requirements for disposal of any products containing mercury. Never put products which contain mercury in the trash. Call your local refuse or Disposal Company or the State Environmental Protection agency and ask how to properly dispose of products which contain mercury.
