mma s a Dr. 0 S. Kurt J. H. Hvguet Hovmb3? 2,5p 19^6 Subject: TE h6~k< 7, Air caldea at SchuylScLll Products Go, Plant this report covers the second air .contamination-.'survey;carried out at the-.Schuylkill lead eselter snd includes all air..analyses mad .-since the first survey, reported in a memorandum of August 2, 1946 from E. H. Eoberi to. Turner, Data from both survey are reviewed end evaluated, 1 The purpose of the oecond purvey tas (1) to dstormins if improve: plant operation plus the wetting-dorm of dusty areas and piles of lead-hearing materials has- .decreased plant contamination, and (2) to obtain additional data as a basis for further operational"and process improvements, Tho general plant condition, was' much .better'."during the second -survey than curing the period covered by lir. Hobart*s report, due primarily to. a.;lower: low u'ca"' contamination (the content of air before it in contaminated ..by-the..smelter operation at mi upwind sample point). Tho fact that the adjacent area contamination .{fields-within a half mil radius of the smelter) was much lower indicates that improved smelter operation should be credited with this reduction. -' ---Data are inadquat to show that the wetting-down program has actually reduced the? amount of lead :dust in -the air. However, the greatly improved househooping and general appearance/are sufficient justification' for continuing the program, '-Tibia' vie is -shared -by.'the Schuylkill people. - Tjable 1 repeats the data of the first survey and presents th feta- of the. Qocond enrvpy. --Ebqperiflmt'numbers, revised sample point numbers.; to coincide with'..the permanent edsipl points shorn on Figura 1, and classification letters have been added. Table II shows tho contamination of the various plant areas derived, from the data ,of Tabla I, . . Figure 1 shmis a typical conssatration pattern to be expected, from the values obtained in Table II. The results of these surveys may be sunuaariaed as follows:' 1 By good operation of the fuse collecting system, it is possible to maintain a low adjacent area contamination. This is -desirablefrom, the standpoint of the health of th community and also because .of.the-, resulting increase in plant contamination which occurs when the wind changes following poor operation, :2. Protection is needed (metal'fume respirators)' when tapping furnaces, v?orking near dust, and. in -general, :throughout th smelter area. Wind direction and low arad" eontaiaiaaticn diefest the; -opeh areas where respirators; are" not required, Hoods -over pots should reduce -smelter contamination. 4 4 0062633 - ; 3 Kiln operation ia not so bad as might be expected,however* kiln cleaning is hazardous. ' ' .. ' ' ' . - 4,, The dust concentration in the laboratory exceeded the tolerable limits and a laboratory annex for crushing, grinding and sampling waa provided:.to lessen the dust exposure in the laboratory.' 5. 'Normal'tack loss (battery plate charge) is 8 lb./day/furnacso Recommandations A system of hoods is presently being installed over the kettles. It is recommended that their effectiveness be studied by additional air analyses It is further recommended that areas adjacent to the Ethyl plant be studied to determine the extent of reverberatory furnace stack contamination. Remarks The Medical Department has dona extensive work on correlating analyses of blood and urine on-Schuylkill employeea. his report should be of assistance to thorn in further studies of cause and effect. Tha cooperative assistance of 'all those who participated-in this work is acknowledged,-, particularly th Safety Departisant, the Schuylkill Management, and other Development Section personnel engaged in making the tests.
