For decades, manufacturers have packed the foam cushions inside sofas, loveseats and upholstered chairs in homes across America with toxic flame retardants. Companies did this even though research shows the chemicals - linked to cancer, developmental problems and impaired fertility - don't slow fires and are migrating into the bodies of adults and children. That began to change in 2012 when the Chicago Tribune's investigative series “Playing With Fire” exposed how the chemical and tobacco industries waged a deceptive, decades-long campaign to promote the use of flame retardant furniture and downplay the hazards. As a result of the series, historic reforms are underway, and flame retardants became one of the top public health issues of the year. The series sparked two U.S. Senate hearings and the Environmental Protection Agency began a broad investigation. Most importantly, California announced it would scrap the rule responsible for flame retardants' presence in homes throughout the nation.
