Two male workers were acutely intoxicated with gas produced by heating tar epoxy resin paint, and developed peripheral neuropathy. To assess the work atmosphere, we analyzed the degradation products by GC-MS. The major toxic products emitted by heating tar epoxy resin were hydrogen cyanide, phenol, and benzene, as well as naphthalene. From 1 m2 of the surface of steel plates painted with tar epoxy resin, 2.4 g of hydrogen cyanide, 9.6 g of benzene, and 1.2 g of nephthalene were produced by heating at 1000 degrees C, At 700 degrees C, the amounts of phenol and p-isopropylphenol produced were 3.7 g and 0.57 g, respectively. Based on these results and the area of steel surface burned, the concentration of hydrogen cyanide, benzene, and phenol in the atmosphere of work environment was estimated to be 16, 64 and 24 mg/m3, respectively. Some of the symptoms of the workers including peripheral neuropathy might be related to the sole or cooperative action of the foregoing toxic chemicals mentioned above.
