A new law in California will require all homes in the state to install carbon monoxide detection hardware by the end of June. It is hoped that the law, SB 183, will save many lives. The carbon monoxide detectors alert residents to dangerous levels of the gas, which is invisible and has no odor, so it can result in serious health consequences and even death if not detected promptly.
At lower concentrations it causes vague symptoms but can quickly lead to loss of consciousness at higher levels. The new law only applies to homes that have appliances running on fossil fuels, and to those that have fireplaces and attached garages as well. All other residences in the state have until January 1, 2013 to get the detectors installed. These small devices cost around $20, and can be found at various hardware and home improvement stores.
