| Abstract: | Common floor-coverings, carpet, synthetic turf, vinyl flooring and pad (underlay) were exposed to a real-life fire environment consisting of an ordinary combustible fuel load in a room. Samples of the floor-coverings were recovered immediately after extinguishment and subjected to laboratory testing using heated head space and charcoal trap-carbon disulphide extraction. Polyethylene/polypropylene synthetic turf and polyurethane padding were found to present a significant volatile signature after such exposure. In a second test, several floor-coverings were burned in a room fire involving the use of three common petroleum products. None of the floor-coverings presented significant interference to identification of these accelerants in the post-fire debris; however, they were found to generate volatiles which might be mistaken for synthetic blends or specialist solvents. The difficulties and value of reproducing full-scale environments and their effects on combustibles are discussed. |
