Anything that burns fuel can potentially become a source of carbon monoxide, an invisible, odorless gas that can kill. CO alarms should be installed in a central location outside each bedroom and on every level of the home. The safety tips for CO detectors mirror those of smoke alarms: change the batteries, test them and interconnect them, if possible. Also, make sure vents for your gas appliances (fireplace, dryer, stove and furnace) are free and clear of snow or debris.
