Morton Chemical Division 101 Carnegie Center Princeton, NJ 08540 Dear Mr. Fabriele: Our Aberdeen, MS plant purchases 2-Mercaptoethanol from your company. An inconsistency in product hazard warning information has been brought to my attention which must be clarified. Your Material Safety Data Sheet indicates the product is classed as a DOT combustible liquid. However, the drums we receive from you are marked with a DOT Poison B label. There is no information on the MSDS you sent us in September that would indicate this material to be a poison. To assure proper handling procedures and product labeling, it is essential that this discrepancy be clarified. Please respond to me in writing as to the proper classification of this product. Your assistance in this matter is appreciated. Sincerely, N\ Thomas G. Grumbles, CIH Environmental Quality Manager ajo/7 cc Ken Birck VVV 000016539
