SECTION OP OCCUPATIONAL HEALTH YALE UNIVERSITY SCHOOL OF MEDICINE DEPARTMENT OF PUBLIC HEALTH 3 io CEDAR STREET NEW HAVEN n, CONNECTICUT H. Bmat tally, R.D. Medical Direotor Monsanto Chemical Company St, Louis 4, Ulssour1 Star Doctor tallyi May 7, 1964 " - i' ' Thanks far your lsttsr of April 28th. Our observations of ohlaraone (mostly quits mild) ware confusing to me too. That was ona reason for publishing the data, slnoa there is a tendency ' among all of us to assume that oertaia conditions oan be characterised as "safe" on the basis of environmental studies alone. Rone of us hare (including the State Health Department Survey people) have any good answer to why the air saaplaa were so low. Re secures that somehow other eonditlon* nay have existed for e few weeks-or months prior to the reoognitloa of ohloraono. Organic aold A did not eontaln ohlcrlne, nor did anything olso la the partioular building. However, the produet may have played a part, although by itself it mots.only as an irritant (it la paokagad at a powder). The Aroohlor was from ona of the large suppliers end was a combination of high boiling ohlcrinated hydroearbona. Slnos the repair* on the circulating system there have been no more oases - over e tbre* year parted. My conclusion Is that ohlorlnated hydrooarbona should ultimately be Judged as safe *r haxardoua la ralatlon to observation of worker* thornselves. 8tudy of tho onriranmsnt would stem et host to b# only a guide/. On* of our purpose* was to stimulate interest in oooupatlonal audioins. I hop# the artlole will net oeus* e rash of claims. It seemed to us that the diagnosis of ehloraena was so spaelfio that any competent dermatologist oould make it. Therefore, disputed eases ehould not be frequent. On the other head, if even mild ohlarecn* is occurring, management reprceentativee would want their dootors to bo alert to it, at it would soon to bo a preventable condition. Finally, I an not suggesting that the m.a.e, for Aroolor has bean eat too high. It will take years of observation and azperlenos to determine this. Our "outbreak* any have been an laolated expcrlsno* net likely to bo duplicated, In that eonneetion, it would bo helpful and informative If yon oould publish your oxperionoa on exposures over long periods to these substances. Re need many mors reports to hate a heel* for .col Judgement. Ritli best regards to you and RlBinr Rheolei. JIM inf*
