The study, published in the American Journal of Preventive Medicine, looked at data from 2000 to 2008. More than 30,000 people die from accidents in the home each year, the study found. The three leading causes of accidental deaths were poisonings (43 percent), falls (34 percent), and fire or burn injuries (9 percent). Firearm mishaps accounted for just 1 percent of all accidental deaths in the home.
