Officials would like to remind everyone that November is Carbon Monoxide Awareness month.
With the cooler temperatures, most people will start to use heaters, fireplaces and furnaces. All of these appliances produce a certain amount of carbon monoxide, which is colorless and odorless.
Across the nation, about 480 people a year die from carbon monoxide poisoning, officials note.
Carbon monoxide alarms are already required by state law to be in every California home. By the start of 2013, apartments and other dwellings will also be required to have one.
A quick perusal of Amazon shows that a carbon monoxide alarm can go from around $19 to upwards of $30.
