Carbon monoxide (CO) is a colorless, odorless gas that is often called the "silent killer". It is created when fuel source doesn't burn completely. CO gas can kill people and pets.
Washington State law (RCW 19.27.530) requires carbon monoxide alarms to be installed in new homes. As of January 1, 2013, carbon monoxide alarms are required in existing homes, apartments and condominium properties, with some exceptions.
Installing CO alarms
Installing CO alarms can give you an early warning if CO is detected in your home and protect your family and pets. CO alarms should be installed outside of each separate sleeping area and on every level of the home. Follow the manufacturer's instructions for installation and maintenance.
Maintenance of alarms
Just like smoke alarms, CO alarms have to be maintained over their lifespan. If your alarm is beeping every 30 seconds, the battery may need to be changed or the alarm has reached its end of life. Most CO alarms last up to 7 years. Replace the CO alarm according to manufacturer’s instructions or when the end-of-life signal sounds.
Go outside and call 911 if:
- The alarm is beeping continuously without stopping, which could indicate CO is present.
- You feel sudden signs of CO poisoning such as dizziness, headache, vomiting or flu like symptoms.
