According to national statistics from the centers for disease control, carbon monoxide kills more than five hundred people and accounts for an estimated twenty thousand emergency department visits annually. Specifically, Washington state has experienced the dire effects of carbon monoxide poisoning. In the storms that struck Washington in December 2006, it was estimated that over one thousand people in the state were seen at hospital emergency rooms with symptoms of carbon monoxide poisoning, and eight people reportedly died of carbon monoxide exposure. It is the intent of the legislature to implement policies to prevent similar tragedies from occurring in the future." [ 2009 c 313 § 1.]
