Kehoe ^ Dr. B. W.Doty Mr. 3, F.Koebal Toxicity Investigation S. 5. Hinaman Garage Gridley ~ Sacramento, California Sow lork Los Angelos September 19, 1952 The following is a brief summary of the investigation of a reported lead poisoning incident. This, coupled with th attached copy of John Koehnle's report, gives the couplet (feta of our participation in this investigation. Thursday August 21st, John Koehnle received a report from Union that had died of a ruptured liver, and that several other Esnwowffitt^S^his garage ware ill. After talking with Or. Doty and having 1dm talk with Or. Keho, we instructed John Koehnle to mice an investigation on Friday, August 22nd, and report to us. Th original report mentioned that competition ted first been called in and had told Union Oil Company, who delivered gasoline to th garage, to turn it over to us, since we furnished lead to Union in that area, Th original information indicated that the death might have been caused from lead poisoning. On Monday, August 25th, Ik*. Doty and 1 met John Koehnle in Sacramento and mads an investigation at Grldlsy. Dr. Doty handled th medical in vestigation with th local doctors, and I looked over the garag. V mat Dr, Carry - who took re of John Perrys Br* Bartsehi - who was taking care of Lloyd Bigerstaff, J. L. Brothers, B. A. Bears and J, Enr&sj and Dr. Msrphy, Countb Health Officer for But County . offices In Ohio. q took load analyses at th garage and found two samples gav an absolute ssro reading. This information, coupled with other data, Indicated to us that lead was in no way involved. After leaving Grldley, and discussing th subject with Sr. Doty . h was of th opinion that tea causa of the death and th illness of the other men whose symptoms were exactly the same as Mr.^fljjjPtwho died, indicated that it might be hydraearbon poisoning* On Dr, Doty's return to Dos Angeles he discussed the subject with Dr. Rutherford Johnstone, a Toxicologist in loa Angeles, and with Dr, Kehoe, Mite what information that was available, they felt that it might be chlorinated hydraearbon poison ing. 19, 1952 they bad been using Bendix "2-fetal CleneB, and Halite Formula 555a for cleaning carburetor and fuel pump parts*. Before our visit to Sacramento, Ur* Doty and X wore able to obtain rather complete information on tbs composition on the ttKlite% which lias chlorinated solvents plus detergents which were sulphurn&tsd hydr&carbons plus other ingredients* Dr, Doty will undoubtedly cover a complete analysis in his report* We were unable to learn the chemical analysis of the Bendlx cleaner* On my visit X found that the Bendix cleaner had been used for quite a number of months, and was almost "spent Therefor, they had bought Kelite to take its place* The Bendix cleaner ted been used to about July 15th, and the Selite was started to be used somewhere about July 1st* On John Koehnle1s investigation he found that both five gallon earn of cleaner ware open sitting in the garage. The Bendix cleaner was sitting next to the heating and ventilating system, and the "Kelit" was sitting next to the carburetor work bench* Their heating and ventilating system consisted of a rather large blower in one side of the garage, which picks air up at about three feet off of the floor of the garage, and circulates it through a duet system over head that blows directly down where the men work* This air is heat ing in the winter time, and circulated in the summer time for cooling. After leaving Gridley, and discussing the possibility of hydra<mrbon poisoning with Dr* Doty - X suggested that the testing system would be a perfect distribution system for hydrocarbon vapors, however, we did not determine any source from which the vapors could have com* It is signifi cant that the stock man ia also showing symptoms and. at m time works out in the .garage in cleaning parts- or mopping floors and such* : Upon receipt of a negative answer from Bxvi)oty*s blood and urine samples, the Sales tepartaent will discontinue further work on tbs project* Wo feel that in this invsstigatioa we have been of definite service to our customer, the I M o a Oil Company, where competition pulled out* V " . very truly, Y-v" ABKsdo.

August 29, 1952 TO AAC:: IT HAT CCUCERU: These men are trie employees of the 3. S. Hinenan Garage, in Cridlcy, California, in whom there was seme question of J5L intoxication: industrial medical History: This nan first began working at the 0 . 3, Rineman garage in 19 gl. Since that tine, he lias done all types of work around the garage, but be has worked primarily in tho mechanical Department and in the Service Station. Many tines, while in the Mechanical Department, ho has dipped automotive parts in five-gallon buckets of gasoline, but as to the exact number of tines-- daily or meekly-- it is difficult to ascertain: however, lie does state that on occasion, then he has dipped his hands in the gasoline, his hands have become numb from the mixture, (Dote: This mixture is apparently not -- gasoline, but contains two and one-half gallons of Union Oil '76 gasoline, plus -approximately one quart of lubricating or drainage oil,) On occasion, lie has also dipped automotive parts in a solution of Kelite, but this has been rare. Past History:: This patient had the usual childhood diseases. In April of this year, be had an operation for correction of Stro.bisr.ius of his right eye. This apparently mas a congenital abnormality. He was rejected from the United States Army because of this eye and because of rather parked Pes Planus Present illness: On or about August 1$} 1992, the patient vrent to bed feeling quite well, but during the night he was awakened by an intense burning and itching of his hands. He noticed that his fingers contained numerous rather large bullae; these were apparently primarily on the dorsum of the fingers. Ey the following morning, he also noticed KB 001233 r Pace three his hands and the soles of his feet. He had no other symptoms of any kind-- no headache, no frequency of urination, no pain in his extremities, no constipation, no diarrhea. Past History: The patient had the usual childhood diseases without any serious illness of any kind. He has also had some constipation, but he has frequenti;." been told by his doctor that this was due to "pure laziness". During the time he was in the army, he suffered an injury'to his ear, but otherwise he has had no injuries or serious illnesses. Ucamination:: Ilnnination. of this patient was negative except for the presence of rather snail vesicles around the tips of the fingers, pains of the hands, and soles of the feet. These vesicles were very small. There was no evidence of any bullae-- past or present, lamination of the abdomen revealed the liver margin to be palpable and tender. Sxanination was otherwise negative. Industrial iedical History: This man has worked for the S, S. idnenan garage since 19h9* he has also worked in the Parts Department, At the present time, he calls himself the"lh.nag;er of the Parts Department", he has only dipped his hands in the oil mixture,or the Bendix.solution, or the Eelite, on rare occasions when he has been out to the Mechanical Department to inspect a broken part. In fact, he very infrequently lias any contact directly with any of these solutions. Very thorough questioning of this man revealed that, to the best of his knowledge, he load done nothing unusual, either in ids work or at hone. Present illness: This man also began having small blisters on his hands and feet approximately one week ago. He describes those areas as itelling severely and then, before ho was aware of the fact, the snail blisters began to appear. The itching was most intense, especially in the areas where he perspired a great deal. He did not develop any bullae. Past History: This man had the usual childhood diseases. He has been Page four in good health, except for the fact that he has had some hay fever which has never been disabling in any tray* Ee has never had ai$r history of allergies, . Txanination revealed some snail vesicles around the tips of the fingers, the palms of the hands, and the soles of the feet. The liver margin was palpable and tender. There were no other abnormal physical findings. Comnent! It vas the- usual custom, in this garage, to wash up the floor nightly with Union Oil #76 gasoline. This ivas done by putting gasoline on the soiled areas and where there was excessive grease,- . putting rice hulls on, then sweeping up the mixture, mono of the men mentioned, have ever had anything to do with, this cleaning-up job; the man who docs this is, to the best of my knowledge, in good health at the present time* Hr. Brothers told me that many timos as he ivas opened cans of Kelite, h.e has noticed a strong smell of the funes, but this lias lasted only a few seconds. The automotive parts were apparently cleaned by putting them into a basket and then dipping the basket in either the Kelite or the fendix solution. The basket was then taken out of the cleaner and carried away and washed with a hose. 1 did not look at the working environment myself, but this was thoroughly checked, by Ur. Chenault and -or. Koehnle, of the Ethyl Safety department. The report will be forthcoming from Ur.Chenault. EODUcK U. m . \ E^fTT^ot^mTS 0 900 Fine Avenue Long Beach 13, California ? 0013639
