MADISON, Wis. (AP) -- All homes and duplexes in Wisconsin will be required to contain carbon monoxide detectors as a safety precaution staring Feb. 1.
There is no penalty for not complying.
The law was passed and signed into law last year.
It requires detectors on every level of the home, including the basement, but not the attic or storage areas. Supporters say the requirement will save lives, even though there is no penalty for ignoring it.
Any dwelling that requires a building permit will be required to have carbon monoxide detectors directly wired to the electrical service with a backup battery. Existing buildings can use stand-alone battery powered detectors.
It's estimated that up to 2,000 Americans die every year from carbon monoxide poisoning.
