The acute inhalation toxicity of smoke produced by five halogenated polymers used as electrical wire coatings was investigated in this study. The polymers in cluded two chlorofluoropolymers (Halar 500® and Halar 555®) and three fluoro polymers (Teflon 100® , Tefzel 200® and Kynar® ). The toxicity of each material was evaluated under flaming and nonflaming combustion using the NBS developmental protocol supplemented with measurement of incapacitation and analyses of the combustion atmospheres for HF, HCl and COF2.
