Rochester, MN (KROC AM News) - Minnesota will become the first state in the nation to require carbon monoxide detectors and warning stickers on certain boats. Sophia’s law takes effect May 1st.

“Carbon monoxide is a hidden danger,” said Adam Block, boating law administrator for the Minnesota Department of Natural Resources. “The deadly gas is odorless, invisible and closely mimics signs of intoxication or seasickness. Even at low levels, carbon monoxide can be lethal.”

Under the new law, functioning, marine-grade carbon monoxide detectors must be installed in recreation motorboats with a designated sleeping accommodation, a galley area with a sink, and a toilet compartment.

All gasoline-powered motorboats with an enclosed occupancy compartment, three carbon monoxide warning stickers are required. The stickers must be attached at the helm, the enclosed occupancy space and the stern.

Warning stickers and information were mailed to registered boat owners in the spring of 2017. Stickers can also be found at all Minnesota deputy registrars and many marinas and marine dealers.

Sophia’s law is named after 7-year-old Sophia Baechler, who died from carbon monoxide poisoning while on her families boat.
