On February 1, 2011, Wisconsin’s new carbon monoxide detector law will go into effect, requiring all homes to have a carbon monoxide detector.
Carbon monoxide is a dangerous, poisonous gas, which cannot be detected by human senses. Dubbed the ”silent killer”, carbon monoxide claims more than 2,000 lives each year and sends more than 40,000 people to the emergency room in the U.S. alone. At high concentrations, carbon monoxide can be fatal within minutes. Twenty-three other states already have laws requiring carbon monoxide alarms in residential properties.
