PENNSYLVANIA A study of this plant "as conducted from March 17 to April 7, 194S by the Industrial Health Section, Health and Welfare Division of the Metropolitan Life Insurance Company to determine the health hazards, if any, associated with the manufacturing operations. Previous studies were made in 1935, 1939 and 1943. . ` The results of the current study led to the following recommendations: ( 1. AH exhaust systems should b kept properly repaired 2nd main tained. 2. Lead free pigments should be used wherever possible. If pig ments containing lead in any form must be used, the Medical and Safety-Deportments should be informed. ** ' 3- Exhaust ventilating systems at pigment or color scales should' . be re-designed to efficiently entrap and remove all dust pro duced by the operation. 4* Periodic samples of urine and/or blood should be collected from those^employees who handle or are exposed to lead pig- ** ' ments or litharge and should be analyzed for lead to determine possible absorption. * In collecting the samples, necessary precautions should be taken to prevent contamination from the bends or clothes of the employees end the samples should be .,, qaalysed by trained, experienced personnel. - 5. Eating should be forbidden in locations There lead pigments $ are used.. Employees who work in these areas should be cautioned to wash hands and face thoroughly before eating. . 6. Employees h&ncll ing lead pigments should be instructed as to the need for careful operating procedures to prevent dis persion of the dust into the atmosphere. rr l > T- -- <. -- 7. 3uildir.~ #59-A - Litharge should be weighed directly into the bucket to be used for charging, rather than being dumped in to the charging bucket from a tared weighing bucket. 3.The exhaust system at the welding table in the Sheet Rletal Shop should be re-desicned to remove the welding fumes at their source. This may best be done by the use of a flex ible, easily adjustable exhaust duct,or by lateral e:iaust . if the nature and size of the work will permit. 9. Lids should be provided for the charging chutes in the Asphalt Tile 3uilding. These chutes should be kept covered except when charging is taking place. 10. Positive exhaust ventilation should be applied to the lead melting pot and at the Douring table in the Machine Shop, Building #30-N. ' 11. The present shot blasting equipment in Building #72 should be replaced with modem equipment that will provide a more efficient method of entrapping and collecting the dust. 12. The use of compressed air for `floor cleaning should be dis continued, also dry sweeping - especially in departments where lead bearing dusts are encountered. Vacuum cleaning methods should be employed. 13- Approved type dust respirators should be used by yard men, and car unloaders in the Sundries Department, when unloading bulk or bagged raw materials - especially when handling asbestos or siliceous materials. 14* The general ventilation in Building #406 should be increased by the use of wall or ceiling ventilating fans, -especially in the area of #3 Lacquer Machine, front end.. 15* Operators at all hopper or mixer charging operations should be instructed to handle with reasonable care all begs of raw material and, after emptying, the bags should be shaken within the effective range of the exhaust hoods. A separate exhaust ed hood should be provided to take care of the shaking and stacking of empty bags where required. 16. The inlay backing-in operation should be studied to devise a method of ventilation to prevent the vapors of mineral spirits from accumulating at the rear of the machine dose to the wall. d W d C tc u -ro+i $ c a. a.

Sizing Department Dust concentrations in this department were low and the free silica con tent of the dust was negligible. No potential health hazard was detected. Bag Cleaning This operation is done in a separate building. The bags are attached to an exhaust duct which draws the bag inside out and into the exhaust duct. That dust is dispersed into the atmosphere is produced by hand handling prior to cleaning. At the time of sampling in this area, .bags that had contained wood flour principally,and a very few with serpentine, were being cleaned. The dust con centration found, considering the comparatively non-toxic nature of.the dust, does not indicate any health hazard. However, when cleaning bags that had con tained more toxic substances, such as asbestos or highly siliceous material, a # ' " dust concentration in the same range would indicate a potential health hazard. *>' * * - Linotile Department ' . "' - . - ' " Dust concentrations were low and no potential hazard'was observed. -N. ' Callender Denartaent "' ' 1 The only potential hazard detected in this department was at the opera tions involving the handling of lead pigments. A mixed sample of colors #35 and #38 was analyzed and found to contain 35*5 ?er cent lead. An air sample, #49, collected at the color weighing operation showed the presence of an average lead concentration of 3.71 milligrams of lead per cubic meter. Samples #46 and #48, - 12 - that the vapor was produced by the heating of the various oils added to the mix. . d--' The irritating condition was noticed principally during unloading of the B & \ jjjixer on the 4th floor, and at the hopper charging area on the 3rd floor. A nan cooler fan is located at the 3 i-^liopper on the 4th floor. The vapors on the 3rd floor can be controlled by keeping the loading chutes closed. Yard Department Exceedingly high dust concentrations were found at wood flour, asbestos hnd whiting car unloading operations. Samples ;fl32 and #133, taken while un loading and stacking bags of Super-fine fir wood flour, and Sample 37, taken rtile unloading whiting, show concentrations exceeding 50 million dust particles per cubic foot of air - a standard now being suggested for non-toxic and non- siliceous dusts, rio respirators are com by the men while unloading. Sample- #134 End #135 show very high dust concentrations for asbestos, . exceeding the maximum allowable' limit of 5 million particles per cubic foot of sir. Although the exposure to the asbestos dust is not constant, it is, however, frequent enough to warrant dust control measures either by exhaust control ecuip-j ' . .. i aent or by the use of personal-respiratory protective devices. The sane crews uf men are used daily for unloading various raw materials. This means that their exposure to high dust concentrations of one kind or another is quite frequent. Cut Order Department, Building #150 -- Inspection and Trimming Building. #155, Crate shop Dent., Building #435. r No excessive or toxic concentrationsof dust or solvent vapors: were found in these departments. * Tube Winding Department, BivilnSng Ah ga Sample #138, taken while cleaning up, is the only sample to show a dust 1___ r .... . ..--......... n AK&TfiOMG COHX COUPANY FLQOfl DIVISION Health Hazards Asbestos /.sbestosis is a pneumoconiosis caused by the inhalation of asbestos dust. It is distinct from silicosis in its pathology and clinical course. As long as asbestos fibers continue to be inhaled, scar tissue develops as a gradually thickening sleeve about the respiratory bronchioles. The stimulus from inhaled asbestos nay be mechanical rather than chenicnl. Asbestosis is a disease which must always be watched for where asbestos dust is present. V.ith respect to tuber culosis and asbestosis, the two diseases nay soerist, but there does not appear to be a predisposition to tuberculosis as is the case v.ith silicosis. The Threshold linit for asbestos dust adopted by the American Conference of Govern mental Hygienists at their 1948 meeting is 5 million particles of asbestos per cubic foot of air. Hood Dust hood dust has possibly a tendency to irritate the upper respiratory tract and, in hypersensitive individuals, may cause asthma and the like. Very rarely .fungous disease is reported as occurring due to the inhalation of rood dust on which molds have grown. Ordinarily, v:ood dust is not hazardous to the lungs. Hhlting The dust of whiting, which is understood to be calcium carbonate, would no" De expected to cause any lung trouble even in fairly high concentretions.
