Carbon Monoxide Detector 04
Carbon Monoxide Detector 04 : Installation: The devices, which retail for $15-$60 USD and are widely available, can either be battery-operated or AC powered (with or without a battery backup). Battery lifetimes have been increasing as the technology has developed and certain battery powered devices now advertise a battery lifetime of over 6 years. Some smoke detectors are equipped with an internal rechargeable battery backup that recharges when the detector is receiving AC power. All CO detectors have "test" buttons like smoke detectors. CO detectors can be placed near the ceiling or near the floor because CO is very close to the same density as air. Since CO is colorless, tasteless and odorless (unlike smoke from a fire), detection in a home environment is impossible without such a warning device. It is a highly toxic inhalant and attaches to thehemoglobin (in the blood stream) with an affinity 200x stronger than oxygen, producing inadequate amounts of oxygen traveling through the body. In North America, detectors are required in new construction in the U.S. states of Alaska, California, Colorado, Connecticut, Florida, Georgia, Illinois, Maryland, Massachusetts, Minnesota, New Jersey, New York, Oregon, Rhode Island, Texas, Vermont, Virginia, Wisconsin and West Virginia, as well as New York City and the Canadian provinces of Ontario and Alberta (homes with a secondary suite or new homes with a fuel-burning appliance). When carbon monoxide detectors were introduced into the market, they had a limited lifespan of 2 years. However technology developments have increased this and many now advertise up to 7 years. Newer models are designed to signal a need to be replaced after that time-span although there are many instances of detectors operating far beyond this point. According to the 2005 edition of the carbon monoxide guidelines, NFPA 720, published by the National Fire Protection Association, sections 5.1.1.1 and 5.1.1.2, all CO detectors "shall be centrally located outside of each separate sleeping area in the immediate vicinity of the bedrooms," and each detector "shall be located on the wall, ceiling or other location as specified in the installation instructions that accompany the unit"
