"I j /*i; i; 5* .'.r. y/C'/ct February 4, 19M Dr. William C. Quinn 1 1521 De la Chaiaa Stroot V Hew Orleena 15, Louisiana V, Hear Dr. Quinni 'i'hia confirms my telephone conversation with you yesterday, concerning Therralnol rn-o. As I explained to you, this ia a chlorinated hydrocarbon, which has been subjooted to considerable toxicological wort, an well ae a long history of use in the hoat transfer field. X, therefore, believe we are in a position to evaluate the ,degreo of hazard to which your maintenance workers might be 'exposed... ,' From the standpoint of acute exposure, one must consider in halation of furaoa which aro evolvod. When the material hits a hosted surface there eould be some breakdown into eldehydoe, CO, and hydrochloric acid fumes, X believe those resulting products would be so obnoxioun that no one would stay long enough to got a serious exposure. One could expect coughing duo to bronchial irritation but, certainly, thle should'not be et all serious. From the standpoint of chronic low level exposure, I would not consider any inhalation exposure from breathing the fumes nt normal tomperatures. If the material wore heated, a dif ferent situation would arise and then one would look for an affect on the liver. Iloro, again, tho material has warning qualities, inasmuch as the odor would be extremely pronounced and dlsagraeable. Tho material can be ebaorbed through tho skin, so good house keeping and the use of gloves are rocommonded. This will avoid the defetting or solvent ection of the material on the skin. \ \ MQNS 090281 Or. William C. Quinn -2- Tebruary 4. 1966 In nummary. 1 can atata that the use of relatively simple procedure! haa been effeetlvo in tho safe uae of thia material aa a boat tranofer agent. If you have any further questions, please let me Know. Sincerely, R. Emmot Kelly, M. 0. Medical Director RKK/ln beet Stan Richa Dicki As I told you on the phone, this man was not too " 1 concerned. He only had two men, who had really a very minor acute exposure. REK HONS 090282
