A bill signed in 2010 by former Governor Arnold Schwarzenegger requiring California homeowners to install carbon monoxide detectors goes into effect today. The bill, authored by Sen. Alan Lowenthal, D-Long Beach, aims to protect against what the California Air Resources Control Board calls "avoidable deaths."
About 40 people per year die from carbon monoxide poisoning, Lowenthal said at the time of the bill's signing.
The law requires alarms to be installed in existing single-family homes with a fossil-fuel burning appliance, fireplace or attached garage. All other residential units will have to have the detectors in place by Jan. 1, 2013.
