Amanda’s Law: Under Amanda’s Law, homes built before January 1, 2008, are permitted to have battery-powered CO alarms, while homes built after this date are required to have the alarms hard-wired into the building. Previously, only homes built or bought after July 30, 2002 were required to have these devices installed. Additionally, Amanda’s Law will require contractors in New York State to install a CO alarm when replacing a hot water tank or furnace if the home is not equipped with an alarm.
On average, about 170 people in the United States die every year from CO produced by non-automotive consumer products. These products include malfunctioning fuel-burning appliances such as furnaces, ranges, water heaters and room heaters; engine-powered equipment such as portable generators; fireplaces; and charcoal that is burned in homes and other enclosed areas.
