From the Oregon Office of Emergency Management:
Loss of power and freezing temperatures have some Oregonians using alternate heating sources, many of which come with the added risk of carbon monoxide poisoning.
Carbon monoxide is a colorless, odorless, toxic gas produced when anything is burned. Gas and oil furnaces, water heaters, fireplaces as well as wood burning and gas stoves are common sources in the home.
