ANNAPOLIS, Md. — Maryland Gov. Martin O’Malley has signed legislation (HB 2/SB 173) into law that requires the installation of carbon monoxide (CO) detectors in new and substantially remodeled public schools in the state.

Maryland is the second state to enact a law to require CO detection in schools. The National Electrical Manufacturers Association (NEMA) advocated for this legislation as well as a similar law enacted in Connecticut in 2011.

“Enactment of this law will help ensure that children, faculty, and support staff are protected from CO dangers while they are away from home,” said Sarah A. Owen, NEMA government relations manager. “Maryland Delegate Cheryl Glenn and Senator Kathy Klausmeier should be commended for their leadership in writing a law that has the potential to save lives, prevent illness, and lessen the amount of time away from school,” she said.

“Many states already require CO detection in homes and apartment buildings, but very few have moved to protect people in other places where they work, sleep, and study,” Owen stated. “Expanding CO detection to schools and other commercial buildings is the next step forward in advancing life safety, and Maryland is one state leading the way.”

To date, 37 states require CO detection in various residential and commercial occupancies. For more information on carbon monoxide, state requirements, and NEMA’s advocacy efforts, visit
