From Monsanto Chemical Company At St. LoulB, Mo. Date August 7, 1956 To PILE At Reference Subject MONTAR This is a series of tarry-like materials recovered from the still bottoms of the Aroclor units. A new bulletin is being prepared to possibly arouse some interest. Some of them are 50-60# chlorinated so I told Svehla we should have a general statement about avoiding skin contact (possibly chloracne?). With our permission, Svehla is putting the following statement in the new bulletin; Subject; Toxicity and Safe Handling Information, Bulletin 0-139, On Montar Compounds "No formal toxicity data exists on Montar compounds. As a general precaution, prolonged skin contact should be avoided, especially when working with solutions of the compounds. Otherwise, the compositions can be handled in the same manner as roofing tar." EPW-.dh Elmer P. Wheeler MUMS 095658
