Mayor Bloomberg signs legislation requiring all newly installed carbon monoxide alarms to have an audible signal and requiring their replacement upon expiration.

The New York City mayor, Michael R. Bloomberg, signed legislation, which requires all new carbon monoxide alarms to have  audible and visual end-of life signals.  In August of 2009, the Underwriters Laboratory standard UL2034 required all CO alarms made after August of that year to have some sort of visual and audible signals.  Typical those signals can be LED and beeper. An end-of-life signal is dictated by the UL standard as 2 beeps and 2 flashes every thirty seconds. This is a very good idea and should be extended to UL2075 for system CO and smoke detectors.

At a Public Hearing in December 2011 on Local Laws Mayor Bloomberg stated "The first of eight bills before me today is Introductory Number 746, sponsored in conjunction with the Administration by Council Members Dilan, Weprin, Jackson, Mark-Viverito, Lander, Barron, Chin, Crowley, Eugene, Ferreras, Gennaro, Greenfield, Mealy, Palma, Recchia, Rose, Van Bramer, Williams and Halloran.  Introductory Number 746 requires all newly installed carbon monoxide alarms to have an audible signal that alerts residents when they expire and requires the replacement of carbon monoxide alarms upon their expiration.”

Carbon monoxide is an odorless and poisonous gas produced by combustion of fossil-fuels, including, gasoline engines, gas lights, BBQ, wood, natural gas, propane and fuel oil.  Some of these fossil fuels are used in furnaces, water heaters, boilers, and other appliances. When the appliance has restricted air or too much fuel the carbon monoxide rises sharply creating a deadly hazard. When something goes wrong such as a bird building a nest in a vent, air intake screen picking up lint and dirt, or improper venting, improper installation, carbon monoxide gas emissions become deadly.

The symptoms of carbon monoxide are considered to be the great imitator often resulting in Flu like symptoms such as headaches, dizziness, giddiness, nausea and eventually unconsciousness and death.

In NYC and hopefully soon in many cities around the country local laws will eliminate, within six months, the old carbon monoxide alarms and detectors from most homes. In my opinion, this will save many lives. In NYC Local Law 7 of 2004 required carbon monoxide alarms to be installed in all dwellings. Therefore all of the NYC alarms installed in 2004, 2005 and 2006 to meet code should be replaced now!

This is true in many other locations as well.  I recommend everyone check their alarms for age if your alarm is over 6 years old replace it now.  Quantum’s products have a replace by date on the side of the cover, which makes it easy to check. In all cases, if you cannot determine the date: replace the alarms NOW!
