In 1976, the tumes generated during the manufacture of the Teaprel hose were investigated by the Environ mental Health Department. While the fumes wore not specifically character!red, certain observations were reported by the investi gators. Diallyl phthalate (DAP), triallyl isocyanurate (TAIC) which has since been replaced by triallyl triaellltate (TATN) and peroxide related aaterials could ba detected in air samples. Howevei belief was expressed (see attachment) that no Simla Tempre1 ingredient, when heated, could produce the irritating fumes associated with Teuprel stock. GC studies related the fumos to poroxtde decomposi tion products and to allyl phthalate but those could not be confirmed in plant samples. Horn recently, customers using Teoprel hoses have complained bout the irritating fumos resulting from the cutting of these materials with hot knives which can approach the pyrolytic decom position temperature of these antorinis. Theso considerations and ( the feme problem at IN Marlon resulted in planned study of the stuck tail ml the fuses gomerated from the ingredients likely to ho responsible withj TtSwAv-BtTaA saanda GuCw/MmS..
