Tests were performed on (1) polyvinyl chloride-containing materials, (2) neoprene compositions, (3) polyurethane foams, and (4) miscellaneous materials (including jute and fiberglass) using a stagnation burner arrangement. In the case of the chlorinated materials, significant quantities of hydrogen chloride were detected; its rate of evolution is strongly temperature dependent. Once glow occurred, carbon monoxide became the predominant toxic species formed. Urethane foams produced cfcl3 and co2 together with some hcl and chlorinated hydrocarbons. Jute compositions liberated methyl chloride as well as other products. A composition of resin reinforced with glass fibers ignited spontaneously at 487 deg. C and produced significant quantities of carbon monoxide.
