Abstract
The use of spray polyurethane foam (SPF) insulation in the United States is increasing. The primary flame retardant used in SPF, Tris (1-chloro-2-propyl) phosphate (TCPP), has been detected in micro-chamber emission experiments investigating SPF. However, due to the use of TCPP in furniture, SPF has not previously been positively identified as a source of indoor TCPP concentrations. This research measured airborne TCPP concentrations in a furniture-free residential test faculty that contained 15 m2 of exposed, two-year-old, open cell SPF.
