Hello I am trying to find out how flame retardants react to heat -- of about 220 degrees F, but possibly as high as 350 degrees. I am thinking about steam cleaning my carpeting and sofa with a machine that reaches these temperatures, (its boiler goes up to 350, and the temperature at the point of contact with the floor is reported to be 220) but I do not want to create/release toxins into my home. To what temperature are flame retardants "safe" and stable before they break down or are released into the environment? Also, can you address, specifically, halogen flame retardants? At what temperature do they break down into dioxins and dioxin-like compounds? Are there any other chemicals that could pose problems when steaming carpet?
