MURPHY Superintendent Risk No. S.I. 2647 Dear Mr. Early: On October 8, 1975 an inspection was conducted at Delco Products at 361 1st Street in Dayton, Ohio, by Michael P. Goyda, an industrial hygienist from the Division of Safety & Hygiene. The inspection was the result of a complaint involving the dust shield welding machines in plant #3. Air samples, were collected at the dust shield welding machines using a personal sampling pump operating at 2 liters per minute and a poly vinyl chloride filter with a 37 millimeter diameter and a 5 micron pore size. The air samples were collected .in the employee's breathing zones. - The air sample results are listed in Table #1. The American Conference of Governmental industrial Hygienists' recommended threshold limit values for total welding fumes and oil mist is 5 mg/M-^ (milligrams per cubic meter). The results obtained during the inspection were below those recommended by the A.C.Q.I.H. There was, however, a mist or fumes being generated at both welding machines and it could produce an unpleasant working environment for the employees operating the machinery. The mist or fumes appeared to be generated three ways: (1) metal fumes from the welding of the parts (2) oil mist from the oil on the metal parts and (3) steam when the hot metals parts were dropped into water. If the metal parts are clean when they are welded, there should be a reduction in the contaminants in the air.

Goyda and Richar^.* M. Maykowski, two industrial hygienists from the Division^?-, of Safety Hygiene. The investigation was to evaluate ` conditions under which the claimant had worked, f- This company manufactures brake systemss^trahsmissionr#^ engine bearings and. powdered metal products*' V. According to information furnished by Don Abbott,^the supervisor of employee benefits, the claimant's work history^ was as follows: .v*'--'-a* " ^ , * V. '' - ' 9/15/70 - 2/26/73- Maintenance Millwright, Plant 5 ' 2/26/73 - 9/22/73 Maintenance Millwright, Main Plaa^, One of the employee's work assignments'was repairing"; the furnaces treating the powdered metal* ; -This repair work, is intermittent and was not being performed during-the" inspection. However, bulk samples were collected in and around the furnaces*.. Bulk samples were also collected of"`: the powdered metals. Since the employment records do not record the exact^r- day to day activity of the claimant and only designate dejraa?t- mental assignment, it was necessary to obtain bulk samples??, of material in all areas where the claimant may ..have received, an exposure to arsenic. * ^ : " r>-rT3C All the samples were sent to the laboratory-for anal^is. The sample results-are listed, in Table The American Conference of Governmental..Industrial . ,v-t| - /"5i  I -- 2 0.5 milligrams of arsenic per cubic meter of air.
