February 15, 2011 > Carbon monoxide detectors Carbon monoxide detectors By Meenu Gupta Carbon Monoxide (CO) is a poisonous gas that cannot be seen, smelled or tasted. Because of this, to make sure that homes are safe from CO problems, installation of carbon monoxide detectors are recommended. According to the Carbon Monoxide Poisoning Prevention Act of 2010 an approved carbon monoxide device listed by the State Fire Marshal should be installed on every level of a home, especially in the sleeping areas, with a fossil fuel burning heater or appliance, fireplace, or an attached garage. Detectors should be installed within the earliest applicable time period for all existing single-family dwelling units on or before July 1, 2011. All other existing dwelling units intended for human occupancy should comply on or before January 1, 2013. With respect to the number and placement of carbon monoxide devices, an owner shall install CO detection devices in a manner consistent with building standards applicable to new construction for the relevant type of occupancy or with the manufacturer's instructions, if it is technically feasible to do so. A carbon monoxide device shall be operable at the time a tenant takes possession. Tenants shall be responsible for notifying the owner or owner's agent if they become aware of an inoperable or deficient carbon monoxide device within his or her unit.
