Manual dial thermostats
Older thermostats with manual dials may contain mercury. Safely dispose of these thermostats for free at a household hazardous waste drop-off location:
Special instructions
- Package thermostat in a puncture-resistant, non-breakable, sealed container like a yogurt or margine tub.
- Label the container as "thermostat" or "mercury" with a permanent marker.
- Call 911 if a thermometer, thermostat, or wall-mounted blood pressure cuff is broken and mercury is released.
Programmable thermostats
Modern digital thermostats (programmable with a display) do not contain mercury. They can be placed in your black cart as garbage.
