Letter to James E. Peavy, M.D., Commissioner of Health, State of Texas, from William M. Johnson, M.D., Acting Deputy Director, Division of Field Studies and Clinical Investigations, NIOSH, dated November 16, 1971 2. Letter to William M. Johnson, M.D, from the undersigned dated November 29, 1971. The subject meeting was requested by the undersigned to a/oid further misunderstanding between Dr, Johnson and the undersigned ,is set forth in Reference 2 above. This meeting was attended by Dr. Joseph K. Wagoner, Director of the Division of Field Studies and Clinical Investigations, NIOSH and several members of his staff and also by Dr. Charles Powell from Ur. Marcus Key's office in Rockville, Maryland. NIOSH expressed their concern for the employees of the Tyler Plant of Pittsburgh Corning whom they felt were being exposed to too much amosite asbestos and were evidencing some adverse effects based on data they had available from their own study of the employees, including n history, auscultation of the chest and inspection of the hands and data on mechanical ventilation studies of the lungs assumed by the undersigned to have been given them by Dr. George Hurst, Director, East Texas Chest Hospital, who is conducting a medical study at the request of and financially supported by Pittsburgh Corning Corporation, They were also concerned that Mr. McMillan, who was the former Plant Manager had died from lung cancer, Mr. Snavely, the Plant Accountant, apparently has a partially disabling lung disease, and one other employee has a pleural lesion as yet undiagnosed. < They felt that little had been done to control the exposure to asbestos at the Tyler Plant since the Public Health Service Study in 1967, while they felt that the conditions at the Port Allegany Plant were much better. They wanted their panel of experts to review the chest x-rays taken of the employees by Dr. Hurst as soon as possible. The undersigned indicated he has also evidenced a long-standing interest in the health of the Tyler employees. He said that following the Public Health Service Industrial Hygiene Survey in 1967, he discussed a medical examination follow-up THIS DOCUMENT WAS NOT A RECORD i L i'' n PPG INDUSTRIES, INC.

The undersigned said that the Public Health Service never got around to performinj these examinations, so in 1971 Dr. Hurst was requested by him to go ahead witl the studies. These studies were delayed until August because of personnel shortages in Dr, Hurst's hospital. These facts were mentioned to put in perspective the urgency of NIOSH now to have their panel of experts review the Hurst films. The undersigned indicated he does not want to unnecessarily delay this review but feels that it will serve the best interest of the employees if the x-rays are released following his meeting with Dr. Hurst on January 5 and 6, 1972, at which time the complete study will be discussed so as to determine (a) If a health problem related to employment exists, (b) If so, the extent of the problem, (c) What further study or clinical care may be indicated, if any. A NIOSH representative was invited to participate in this meeting with Dr. Hurst and the undersigned. The undersigned, again attempting to put the industrial hygiene data obtained at Tyler in 1967 by the Public Health Service into proper perspective, made the following analysis based on a reasonable industrial hygiene interpretation of the data in terms of the TLV for asbestos of 5 million particles per cubic foot of dust. It was pointed out that the material being manufactured was only 607. amosite asbestos, not 100%: (The complete report as submitted to the Tyler Plant Management is shown in Attachment if 1). Mixing Area - 5 samples taken: 5, 13, 9, 7 for a 8 MPPCF average. One sample of 51 was considered contaminated since itwas6X greater than average of other samples. Forming Area Curing 8 samples taken: None above TI.V for 3.1 MPPCF. 1 sample: .1 MPPCF Finishing 6 samples taken: 1.9, 1.6, 2.6, 2.0, 2.4 for 2.1 MPPCF average. One sample was 10.9 and was considered contaminated since it was 5X greater than average of other samples. Inspection 3 samples taken: 2.5, 2.1 for 2.3 MPPCF average. One sample, 45, was considered contaminated since it was 20X greater than average of other samples. In no case was the average of the samples that agreed relatively closely, one with the other, in excess of the then TLV. This TLV was not changed to 12 fibers/ML until 1970, at which time the intended value became TLV. The undersigned pointed out that in a studydone'by University of California at Berkeley, at the request of and supported by Pittsburgh Corning comparing Unibestos and 4 leading asbestos-containing thermal pipe insulation materials indicated that none of these products would be used in cite construction industry without exceeding the 12 fibers/ML TLV and that this study intensified the research effort in Pittsburgh Corning to find an asbestos substitute. Being 0007888l Page 3 W unsuccessful in finding such a product that was economically competitive witli the asbestos-containing products was a factor in the Pittsburgh Corning decision to get out of this market. The undersigned had provided copies of this University of California Study back in September, 1971, to Dr. Johnson. The undersigned requested the following be provided to him, if possible: ) Copy of OCAW request to NIOSH to investigate asbestos exposures at Tyler, Texas. 0^(2) Copy of NIOSH Survey of October 26-29, 1971, at Tyler. ) History and physical findings of NIOSH on Tyler employees.

Pursuant to section 8(c) of the Wllllams-Steiger Occupational Safety and Health Act of 1970 ( 84 8tat. 1598, 29 UB.C. 866), Part 1910 of Title 39, Code of Federal Regulations (38 FR. 10488, May 29, 1971) la hereby amended tn the manner Indicated below in order to pro vide an emergency standard dealing with the expoeure of employees to asbestos dust. In light oi increasing Information on the results of exposure of employees to airborne asbestos dust, including recent studies by the National Institute for Oc cupational Safety and Health and others, and recommendations by the American Conference of Governmental Industrial Hygienists (ACGIH), It Is hereby deter mined that (1) exposure under the pres ent standard for asbestos dust In Table 0-3, 11910.93, of 13 fibers per milliliter greater than 6 microns in length or 2 million particles per cubic loot of air, which Is derived from an established Fed eral standard promulgated under the Walsh-Healey Public Contracts Act on May 30,1989, constitutes a grave danger to employees exposed to this 8-hour time-weighted average concentration; And that (3) an emergency standard Is necessary to protect employees from this excessive exposure. The National insti tute for Occupational Safety and Health concurs that the proposed change in the asbestos dust standard recommended by the American Conference of Governmen tal Industrial Hygienists should be the substantial base for the emergency standard. Action concerning the standard will be commenced tmder section 8(b) in the Immediate future. Any notice of pro posed rulemaking under section 8(b) will give notice of the emergency standard as a proposed rule and also of any ap propriate subsidiary proposals which may be required under subparagraphs (5) and (7) -of section 8(b) relating to the ex posure of employees to toxic substances.

During the week of October 26 - 29, 1971, the National Institute for Occupational Safety and Health conducted a comprehensive industrial hygiene and medical survey of the Pittsburgh-Corning Corporation amosite asbestos thermal pipe insulation plant in Tyler, Texas. The survey pointed out major industrial hygiene deficiencies which included a grossly inadequate ventilation system and poor housekeeping practices. Per- sonal air samples yielded grossly excessive fiber concentrations. One hundred 4 seventeen of 138 samples exceeded 5 fibers/ml for fibers >5p in length. * The National Institute for Occupational Safety and Health medical questioner naires and examinations for rales and clubbing were conducted on 63 male - -* employees in order to complement the X-rays and pulmonary function tests per,r . Even without benefit of interpretation of the X-rays, 7 of 18 workers with 10 or.-/ uj pulmonary function was observed in a few workers with less than 5 years Js j ` r '' employment. ^ f. - " - eiX, In conclusion, an extremely serious and critical occupational health situation exists at this plant. Immediate corrective action is necessary to reduce asbestos exposures to conform to existing standards. Appropriate recommendations are presented in this report. In all areas and operations except the office area, average and maximum concentrations of dust greatly exceeded the presently existing Threshold Limit Value of the American Conference of Governmental Industrial Hygienists and the Emergency Standards of the U. S. Department of Labor (see Table I). ,/ | BB 0007900 1 't . .. .1 i 3TE: THIS DOCUMENT rvn ia-; V n ^ i-* r* ** js ^ r*N > *a. ..i -3- INTRODUCTION AND PURPOSE On October 2G - 29, 1971, at the request of Mr. Martin C. Wukasch of the Texas State Health Department and Local 4202, Oil, Chemical, and Atomic Workers International Union, an environmental and medical survey was made of the Pittsburgh-Corning Corporation plant in Tyler, Texas. The survey was made to determine the level of asbestos dust in the working environment, to evaluate the existing environmental controls for asbestos and to conduct medical questionnaires and examinations for rales and finger clubbing. The study was conducted by the Division of Technical Services and the Division of Field Studies and Clinical Investigations of the National Institute for Occupational Safety and Health (NIOSH). Previous industrial hygiene surveys for asbestos dust were made of this plant in March 19G7 and January 1970. On both occasions the levels for asbestos dust greatly exceeded the threshold limit value (TLV) for asbestos dust as set forth by the American Conference of Governmental Industrial Hygienists (ACGIH). In this study the asbestos dust was also grossly in excess of the existing TLV's (see Table I). DESCRIPTION OF PLANT AND MANUFACTURING OPERATIONS The plant occupies two large buildings approximately 1000 ft. long and 50 ft. wide and covers approximately 100,000 sq.ft. The buildings are approxi mately 30 ft. high with corrugated metal roofs, a wooden shell, and concrete floors. . The plant employs 74 persons, including 62 hourly and 12 salaried employees There are four major departments: 1. Production 2. Finishing 3. Shipping, Receiving and Warehouse p-> ': ; I ,, 4. Maintenance 1 BB 0007901 1 / With the exception of the production department which operates three full shifts, the plant operates only one shift. In this plant asbestos insulation for pipe is manufactured from a variable mixture of asbestos (approximately 90%) and varying amounts of natural diatomaceous earth, sodium silicate and mineral wool. The amosite asbestos used by Pittsburgh-Corning is mined in East Africa. It-arrives at the Tyler plant by railroad cars packaged in polyethylene lined hissian bags with each bag weighing 110 lbs. After the materials are received they are stored and used as needed. There is also a large inventory of "governmental surplus" amosite asbestos in the warehouse. This material is stored in burlap bags without the polyethylene liners. All types of used asbestos bags are sold to nursery companies to wrap trees or they are disposed of in the local dump. When the materials are ready for processing they are placed in material feeders. There are 3 feeder lines with each line having 3 stations. Each station contains different materials. The first station contains the virgin amosite; the second contains mineral wool (at times the final formulation con tains approximately 5% mineral wool). The third station contains scrap. (Scrap is regenerated asbestos and is approximately 25% of the formula.) The new bags of asbestos are placed on top of the feeder and cut with a knife and allowed to fall into the feed hopper. The scrap`is removed from metal containers using a large fork and placed in the feeder hopper. Both systems generate excessive amounts of dust. The diatomaceous earth used in the formula (7%) is`placed in large hoppers and fed by auger to the conveyor system. _BB^0007902~7 conveyor belts to the attrition mill which opens the amosite fibers and blends all the ingredients together. From the attrition mill the material is transported through ducts to the cyclone where the heavy material is separated out and the light material is recycled to the attrition mill. From the cyclone the heavy material goes to the building machines. In the building machine, through a system of spiked belts and lay belts, a lap is formed. The lap is a dry mass of the total blend of the raw materials. Controlling the speed of the spike belt determines the thickness of the lap. The material then goes through a mechanical rake to smooth the lap; it is then sprayed with sodium silicate. Alter the lap is sprayed it exits the building machine and is roiled on a mandrel to desired size. Sand or Perlite is applied at the beginning of the roll to ease the mandrel from the finished roll. It then goes to the finishing mill. From the finishing machine it goes to the coating machine where a clay coating is applied. At the building machine in the roll-up process, small amounts bf the material cling to the lap belt and are scraped off the boLLom side of the turn around drum. This material is gathered up, loaded on a truck and dumped in a large field adjacent to the plant as waste. At the present time no provisions have been made to bury this material. This practice has been carried out for at least 15 years. This produces a serious air pollution problem. After the rolls have been claj' coated they are removed from the mandrel and put into a drying room. From the drying oven the rolls go to the finishing department where the ends are sawed off, split down the middle, bound together with string, packaged and then removed to the warehouse for storage. j BB 0007903 / iHjS finp' m mm emu m ni! ENVIRONMENTAL STUDY PROCEDURES AND INSTRUMENTATION Atmospheric samples for fiber count were collected on Millipore filters, Type AA*, encased in three-piece plastic Millipore aerosol field monitor with face cap removed and filter completely exposed. The samples were taken at the operators' breathing zone using battery powered Mine Safety Appliance (MSA) gravimetric pumps, Type G. The pumps and samplers were worn by the employees. The pumps were calibrated to operate at 1.7 liters/minute with each sample being taken for one hour. Each employee on each shift was sampled at least twice, with some employees on the first shift being samples three times. Ventilation measurements were made using pitot static tubes and a magnehelic gauge. A ten-point traverse was attempted on the larger ducts with a six-point traverse on ducts six inches or smaller. A more detailed report of the ventilation system will appear later in this report. Face velocity measure ments were made on hoods using a thermal anemometer. Noise measurements wore also made of the plant using a General Radio sound level meter. Type 1GG5-A, calibrated at the time of this study. No read ings were found to be above 85dBA. TOXICOLOGY AND HYGIENIC STANDARDS Asbestos is a general name given to a variety of liberous minerals. The major asbestos minerals are chrysotile, crocidolite, arnosite and anthophyllite. Asbestosis, lung cancer, pleural and peritoneal mesotheliomas may follow exposure to asbestos. The risk is related to the length of exposure and the dust concentration. rr iqqiq I; j I ; i ' ^Registered trade name of the Millipore Corp., Bedford, Massachusetts I BB 0007904 j 'w' 3 f' -7- w'-J :L.' rfKcAU?i.VSi O 3` O t <-*- <J O < < -- * The Threshold Limit Value (TLV)* for asbestos dust, as listed in the Threshold Limit Values for 1971 of the ACGHI is 5 million particles per cubic V*,1 foot of air. In 1968, the U.S. Department of Labor (Waish-IIealcy Act) pro ..i ]' mulgated a standard limit of 12 fibers per ml of asbestos, for fibers > 5p in 1 length. On December 7, 1971, the U.S. Department of Labor established an I "Emergency Standard for Asbestos Dust Exposure of 5 libers per milliliter, '<j >5p in length for an eitht-hour weighted exposure. The ceiling exposure con <3 ditions shall not exceed 10 fibers per milliliter >5p in length. " RESULTS OK STUDY A total of 138 personal samples were taken of the various operations at the Tyler plant. These samples were analyzed in the Cincinnati laboratory of i NIOSII. Each of the membrane filters were rendered transparent using a 50:50 mixture of dimethyl phthalato and diethyl ozalato and counted using a 4mrn(43X) phase contrast objective 400X magnification and phase contrast illumination. Counts were recorded for all fibers > 5p. Of the total of 138 samples taken, 117 exceed the presently accepted Hygienic Standards of 5 fibers/ml of air and >5p in length. In all areas and operations, except the office area, average and maximum concentrations of dust greatly exceeded the presently existing TLV of the ACGIH and the Emergency Standard of the U.S. Department of Labor, (see Table I.) The plant was in very poor condition including housekeeping, health hazards, ventilation, and storage and disposal methods. Each aspect will be discussed below. pr | ' CLrj ( BB 00079Q5_2 *TLV Booklet. Threshold limit values refer to airborne concentrations of sub stances and represent conditions under which it is believed that nearly all workers may be repeatedly exposed, day after day, without adverse effect. Because of wide variation in individual susceptibility, however, a small percentage of workers may experience discomfort from some substances at concentrations at or below the threshold limit, a smaller percentage may be affected more seriously by aggra vation of a pre-existing condition or by development of an occupational illness. HOUSEKEEPING The housekeeping was very poor. At the time of our arrival, when a walk through survey was made, the floors, ceilings and rafters had an excessive amount of dust on them. The drinking fountains and eye bubblers were very dirty as were the rest rooms. There were also small piles of dust around the machines that had been swept there by the operators using push brooms. Thus, asbestos dust Was re-disbersed into the work atmosphere. VENTILATION The ventilation system, as a whole, was found to be grossly inadequate. Some of the deficiencies are listed below. NOTE: THIS DOCUMENT DID 1. Blast gates were closed. ^QJ COME FROM RPQ f' L . 3 2. Small ducts on all three feeder stations were plugged. 3.

Many of the ducts are disfigured, probably caused by bumping by machinery. 6. Holes in ducts were repaired by applying Permagum, a putty like substance: 7. Too many 90 entries were attached to the main ducts, which can cause excessive air turbulancc and static press'.re losses. An attempt was made to do a pitot traverse of the ventilation system. This i was impossible since the ducts on each of the three feeder stations were plugged. Static pressure reading could not be made due to holes in the blower housing and the bag collectors. | BB 0007906 | / i 1 < Jt V'" / -* -J .* -j * -9- SCRAP GRINDER The scrap grinder is located north of the feeder stations. Scrap from various operations are ground up to be reused in the process. The operator p must lift the pieces of scrap above his head to feed the grinder. After the -- scrap is ground up it is deposited in a metal container approximately 4'x4' * with wheels. After the container is full it is removed and then taken to the feeder stations where it is reintroduced into the process. The grinding opera-^; otion was very dusty and the ventilation was insufficient. Velocity across the face of the opening was only 20-30 ft./minute (fpm). A slot at the floor level o was pulling approximately 200 fpm but is incorrectly placed; it should be located above and close to the metal container. CO zc MATERIAL FEEDERS The material feeders consist of three lines with each line having three O leZl stations. The duels used to ventilate these stations are located approximately 2 ft. from*the opening of the feeders with each having a 90 entry. The ducts are 4", 5", and G" in diameter, depending on the location to the main duct. Face velocities across each station ranged from 0-15 fpm. A fan located in the area contributed to the turbulence and re-dispersion of dust in the work atmosphere at the feeder stations. There were openings on the feeder stations that allowed the operator to see into the feeder. Although they were equipped with plexiglass they were left open. This also contributed to the dust buildup in the area. The scrap grinder and the feeder stations are on the same collec tion system. This collecting system, consisting of three units of canvas bags with 1G bags in each unit, is located inside the plant. These bags are cleaned by mechanical shaking with the asbestos falling into 55 gallon drums located beneath the bags. There is a large opening between the bags and the drums and when the bags are shaken a large portion of the dust is released to the work area. The spillage, like the spillage from the scrap grinder and the feeders, n r;? 1 BB 0007907 J NOT COME FROM PPGFILES -10- is swept up by using a push broom. Although the plant has a vacuum cleaner it was not used in these areas. BLOCK SAW OPERATION The exhaust on this operation was in the best condition of any in terms . __ of removing the dust at the source. However, the blower assembly and the collector bags had holes in them and the dust exhausted from the operation wasl^y released into the work area. "" LARGE SAW OPERATION In this operation the larger sections of pipe insulation are trimmed. TheOO band saw. At the base on each side of the saw there is a G" duct to exhaust the}j c3 dust. The face velocity at these ducts was measured at 200 fpm. This does ^ good job at the bottom but the dust generated at the top of the cut is released """ to the work area. When the ends are trimmed, the pipe lhen goes to a splitter which makes a cut along the length of the pipe. For exhausting the dust from this operation there is a side draft or suspended hood arrangement. It does a good job of exhausting the dust around the outside and along the cut, but the dust is not removed from the inside of the pipe. When it is removed it is inverted and the dust is released to the work area. There is a considerable amount of dust in this part of the operation. This was the only operation in * , which the dust collector was located on the outside of the building. RESPIRATORS i In 1971, the wearing of respirators was made mandatory in all areas of the plant. Respirators used in the plant were MSA Comfo Mask with BM21B-90 filters. Although they have a definite application, respirators should not be worn as a regular means of protection. Respirators should be used only as an / 7 BB~000790fM w -11- emergency or for backup protection. This does not seem to be the intent at this plant. Unless properly fitted, correctly used, and properly maintained, a respirator may become a hazard because it gives the wearer a false sense of security and permits him to become careless and may add to his exposure, If respirators must be used they should be controlled through a company ^LUj operated program providing for proper selection, fitting, maintenance and cleaning. This part of the program is lacking Since many workers were seen Lr ,f o i'X. with straps too loose, and straps not connected. There is no maintenance and standardization program for the respirators. HEALTH HAZARDS In addition to the health hazard from the amositc asbestos, the following potential hazards were noted: 1. The lunch room is located too close (approximately 40-50 ft.) to ,,. c- j the dustiest operation in the plant. ZzZ 2. Workers are allowed to go into the lunch room wearing clothes contaminated with asbestos. 3. There is a potential health hazard from the diatomaceous earth handling operation. 4. The scrap material that is dumped into the open field may cause a serious community health problem. 5. The sand, used on the .floor to enable cartons to be moved more easily, may present a silica dust problem. ADDITIONAL COMMENTS Some additional potential hazards were observed as follows: 1. There are G homemade natural gas heaters located throughout the plant. Since they arc vented into the plant this may cause carbon monoxide or fire and explosion hazard. | BB 0007909__i / ill llll'l* -12- 2. Compressed air outlets operating at 90 psi are located throughout the plant for the purpose of blowing excess dust off employees. This is I not only a hazard to the employees but it reintroduces the asbestos dust to the working environment. MEDICAL PROGRAM The company lias no in-plant medical facilities or first aid room. Two `~T\J > ,, i first aid cabinets were stocked inadequately, and one first aid cabinet had a door with broken glass. ^ * - , *"* i Occupational health consultation is available from corporate headquarters^ . 7 in. Pittsburgh, Pennsylvania. Dr. Lee Grant, Medical Director of PPG Indus< ' r: tries, Inc., is Medical Consultant to the Pitts burgh-Corning Corporation. ,C, i -_ Employees are sent to the Tyler Medical and Surgical Clinic for X-rays^ ; physical examinations, and emergency care. Pulmonary function and X-rays ,`. were performed on all male employees in August 1971, at the nearby East Texas Che`st Hospital by Dr. George Ilursc, an internist and specialist in chest diseases. , 1.;.; i"- ! - Cl* v / , Diffusion studies and arterial blood gases were obtained on those male employees with greater than 5 years employment. At the present time the workers do not receive pre-employment X-rays due to the high turnover of new personnel; however, after CO days employment chest X-rays are taken. In August 1971, U.S. Bureau of Mines approved respirators were made mandatory throughout the plant concomitant with an application to the Occupa tional Safety and Health Administration, U.S. Departmcntof Labor, for variance from the asbestos standard. In the finishing and batching area of production (feeders and scrap grinders), the use of respirators has been mandatory since 19G5. Safety glasses are required. No protective clothing is issued to employees, and there are 5 air hoses operating at 90 lbs/sq.in-. and located throughout the plant to blow off excessive dust. j* - i -13- Also, the variance request sets forth the requirement: "Continuing health education program on asbestos will be provided. " However, dur 1 ing the present survey, many employees apparently were unaware of th^ serious implications of asbestos exposure, 1 & MEDICAL DATA AND HECOMMENDAT C^vkA j. v Asbestos is a general name given to a Variety of fibrous minerals. The major asbestos minerals are chrysotile, crocidolite, amosite, and antlmophylite. Amosite is used exclusively aL this plant in the pro duction of thermal pipe insulation. Asbestos-r elated diseases have been well documented in the medical and occupational health literature. The risk of developing asbestosis or pulmonary fibrosis varies directly with length of exposure and concentration of exposure. The association between occupational exposure to asbestos and lung cancer, pleural mesothelioma, and peritonial mesothelioma is recognized. NIOSII industrial hygiene surveys in 19G7 and 1970 yielded grossly excessive fiber concentrations compared to current and proposed standards. Again, the present survey yielded grossly excessive fiber concentrations in all production, finishing, and shipping areas. ,- , ,,r : . ! .. : n | BB 0007911 I NIOSII medical questionnaires and examinations for rales and finger clubbing were conducted by our survey team on 63 male employees in order to complement the X-rays and pulmonary function tests performed by Dr. George Hurst of the Hast Texas Chest Hospital in August 1971, at the request of the Pitts burgh-Corning Corporation. Several films were read as possible pulmonary fibrosis. Dr. Lee Grant, Medical Consultant to Pittsburgh-Coming Corporation, lias delayed release of these films to NIOSII and its expert panel of radiologists pending his personal review of the X-rays, Even without benefit of X-rays, 7 of 18 workers with 10 or more years employment at the Tyler plant meet at least 3 of 4 criteria for asbestosis. These criteria include: 1. Forced vital capacity below 80% nf nrediH-.TM! 2. Dyspnea. 3. Finger clubbing. 4. Hales. Positive X-rays could increase further the number of cases of asbestosis. Reduced pulmonary function was also observed in a few workers with less than five years employment. In conclusion, the following medical recommendations arc set forth; 1. Chest X-rays obtained in August 1971, should be forwarded to NIOSII and its expert panel of radiologists for the benefit of the T3'ler employees. ' 2. Reduction of asbestos-exposure levels to conform to existing standards is imperative in order to prevent any irreversible pulmonary damage. 3, Following a review of the X-rays, further' and mope specific medical recommendations will be made. 4. Medical follow-up of present and past employees is indicated. Certainly asbestosis has been reported to progress following cessation of asbestos exposure. 1~b1T0007912_| D\Ub- ..nTPTWSDOCUWEjW 1 s DISCUSSION AND CONCLUSIONS SWjw>w?pg Inhalation of asbestos dust has long been recognized as a serious occupational health hazard. Asbestos-related health effects were detected in many Tyler employees. This plant has been in operation since 1954. NIOSII surveys in 19G7 and 1970 yielded excessive fiber concentrations, and again, this survey yielded fiber concentrations grossly in excess of current and proposed standards. Housekeeping practices and the ventilation sj'stem were inadequate. According to the APIA Industrial Ventilation Manual, a minimum capture velocity of 200 fpm at the face of the material feeders and a duct velocity of 3500 to 4500 fpm should be maintained. Since the open area of the material feeders is approximately 9 sq.ft., the minimum effective air movement would be 8 ft. x 200 fpm = 1GO0 cfm, The currying velocity in the main duct should be approximately 3100 cfm. The present system does not meet these criteria. The respirator program is inadequate and does not offer sufficient pro tection. In conclusion, immediate measures should be taken to insure the employees a safe and health work environment. Further asbestos exposure could result in irreversible pulmonary damage. Immediate corrective action is mandatory and the following industrial hygiene recommendations are set forth: 1. A complete redesign of the ventilation system. 2. Locate all dust collectors on outside building and tquip collectors with automatic shakers. 3. Appoint a safety committee to educate employees to hazards of asbestos. rr I? r - 0 4. Remove all homemade gas healers from the plant. >.;'j | ,, ; ) | BB 0007913 | 5. Do not allow employees to use compressed air to remove dust from clothes. C. Establish a company operated and controlled respirator program providing for proper selection, fitting, maintenance and cleaning. 7. The lunch room should be located in a clean area of the plant and employees should not be allowed to enter with dirty clothing. 8. All employees should be issued protective c lothing such as coveralls and cotton caps and these clothes should bo removed before eating and before going home. 9. All scrap materials should be buried. 10. Used asbestos bags should be buried also and not sold to nurseries or removed to the local dump. 11. Do not use sand on floor to transport cartons.

This survey was don by the State of Pennsylvania, k nueher of the enployeee In this plant, namely, the copes/erloader, building operator and some of the saw operators were exposed to asbestos dust exceeding the TLV of five million particles per cubic foot of air. In addition to tha UO regular enployees in this department, there are about 6 service department employees who spend all of th* time in the asbestos department. Others exposed to asbestos are unloaders who about once every U or 5 months spend h to 5 days unloading burlap bags containing asbestos from box cars. These unloaders are usually from the work gang and are not the same people used each time. The ingredients are scrap, DX and DX-11 which are two forms ef asbestos (incidentally, this asbestos comes from Africa and is aeoeltotype* It hss a relatively high specific gravity and it is not shredded as much as the asbestos in the textile industry is shredded, both of which increase its settling rate from the air. Dicalite Grade 185 is a diatomaceous earth that is supplied by Great Lakes Carbon Corporation and is shipped from California. About 2 to 3 bags of this material are used per eight-hour shift as a filler material. These ingredients are chopped up and mixed and pneumatically conveyed to a building machine where they are laid down on a conveyer. They are then sprayed with a liquid solution of souium silicate which is about 80$ water and 20$ silicate. This material is received from Dupont or Philadelphia Quartz.

Only pre-eeployment X-rays have been done on any f the e^>loyeas in this area* 3. The Port Allegany Plant was started up in 1937 as a glass block plant. In 19k2, foam glass was added - in 1955, fabrication of foam glass ded - in 1961, the urethane foam was added - in 196k, unlbestos was k. Trethsam Foam Department, Shortly after the start up of this operation, the Industrial Hygiene Foundation did a survey of this area and generally found conditions well-controlled with no significant exposure to TDI. In the operation, a prepolymer prepared by the Chase Cheedcal Company oonelsting of a polyall resin and TDI are combined with a premix which is made ig> on site and consists of polyall resins and some silicones and a catalyst sad other materials* When these materials are combined, there is a levlning effect and a hardening effect which produces the bun. This is ell done under what appeared to be adequate exhaust ventilation, however, the exhaust fumes are ventilated to the outside and are not scrubbed out. There have been a number of people who have been sensitized by the TDI including the plant manager. Nr. Larry Griffith. Therefore, it is doubtful whether the controls are entirely adequate. Further fabrication of the bun takes place in a tengwrary like loose plastic hood area where the buns are cut with hot steel wires of various sizes. Recently, in addition to the exhaust ventilation of this teng>orary like hood, they have also placed local exhaust ventilation on each of the cutting arms where the wires are attached. This seems to be quite effective in fume capture. 5. Glass Foam. One batch house provides batch for both the foam glass tank which is tank no. 2 and the glass block tank which is Tank No. 1. The basic batch for the two tanks varies only in the cullet. The glass block uses glass block cullet and the foam glass uses foam glass scrap. The batch consists of a Bepleton sand, a Barberton soda ash, rascrite which is a borax material, limestone and a methylene cyanide. The batch house is a threeshift operation in which there is an unloader, batch house operator and two ndjdng and malting maintenance people. An additional batch house operator is addad when they are on two tanks. A five-gallon pail of levining is added to the foam glass in addition to the normal batch. This consists of sodium nitrate, sodium sulfate and fluorospar. The batch is fed into the tank with a fraser simplex screw type charger. This is a completely sealed operation as opposed to the usual open feeding in other glass tanks. Tank No. 1 which is only used about half the time is kept in heat between production runs. About 80 tons of foam glass is made per day - maximum capacity is about 85. THIS DOCUMENT WAS NOT A RECORD OF PPG INDUSTRIES, INC.

Glass Brick. This production operation is reminiscent of the optical tank operation at Works 6. The molten glass is extruded like tooth paste into these molds which ere on a rotating disc. The molds of the two halves at the final glass brick. These molds are then welding together much like In the glassweld operation at Lincoln following which they are put into a lehr and slowly cooled following a heating up to close to melting tempera tures* After taking them off the lehr, they are sprayed fl with a prims coat whloh is a hydrolyzed ethyl silicate and then a vinyl coat which is vinyl mersol. These coats are to provide a bond layer or an expansion layer between the glass and the mortar used to hold the glass bricks in place much as the mortar used in regular house bricks. The coat is then allowed to air dry and then packed and shipped. Mr. Roy Thompson is an employee who is sus pected of having lead poisoning by his personal physician. Dr. Herman Moush. Dr. Moush is a friend of the plant industrial relations director, so I called Dr. Moush to discuss his findings. I also talked with Mr. Thompson about his conplaints. The complaints and findings seem to be more closely related to hypertensive- cardiovascular disease with the exception of a cramping and soreness of the stomach that Mr. Thompson has cooplained of within the last year. This, of course, could be caused by the pathology of the gastro intestinal tract not related to lead intoxication. No gastro-intestinal studies have bean mads. Mr. Thompson complained of the dry paint causing his fingers to peel and crack. He said that while he was paint spraying, he kept his hands in rubber gloves and perspired a good deal under this and this caused his hands to be wet a good bit of the time. He had been working on this operation for about 3 years and it was only one year ago that he began to notice this fingernail infection which resembled very strongly a fungus infection. In discussion with Dr. Moush about Mr. Thompson, I suggested that I would obtain a lead urine anafcrsis in not only Mr. Thompson but also other employees doing the same type of work and if these indicated an exposure, I'd have further industrial hygiene studies done to determine the source of the exposure.

TtlflsIaQ, was about thrss week* before tbs undersigned's visit. fh. Thompson war removed from his exposure at that tins and placed at the foes Class finishing area. His doctor had placed him on TttA, a chelating agent. The sigiloye* has noted an i^irovvmsnt in sons of his syvtons since the beginning of this tres'-amot. The glase dkcorutlng operation conelste of spraying a base enamel on the glees blook, allowing this to sir dry and then firing the enamel into the glass block. The spraying is done in e makeshift, but enclosed, ventilated box which Is completely enclosed et the tine the spraying is dons. The spraying is activated by a foot lever outside this box. The vet sprayed block is then reaoved and placed on e pellet where it is allowed to air dry. The spraying operator wears rubber gloves during this phase of the operation. V fairly large number of blocks are allowed to scoumiilete in this manner before they are taken into" the next room and placed on a conveyer line which carries them through a firing furnace. The firing furnaua is exhaust ventilated. Prior to firing, the arled enamel is powdery and can easily be wiped off the glees bricks. The Technical inrector of Pittsburgh Corning, Mr. usorge ursgory, advised that the base enamel contained between 1*5 end 51 percent of lead oxide. Mr. Thomson baa a history of hypertensive oardiovaecular dlse-.se. tie also has --: e fungus infaction of the fingernails. Ho special study has been made cf his gastrointestinal coaplaiots. ~~ " Weirni--nrlation While there is a potential lead hasard, n/ initial observations of the opera* tlon as it waa being done et the time of my visit, lead me to believe that it is probable no lead hasard aotuaUy exists. However, in view of the question that has been raised in regard to potential lead Intoxication, i would strongly suggest obtaining lead urine studies not only on Mr. Thomson but on all of the e^loyees who have recently worked et this operation for significant periods of tine* 31nee these lead urine st jdiss cannot be done in the usual hospital laboratory, upon request, I will oako the necessary arrangensnts to have those studios be accomplished. r*e studies consist of each employee collecting a 21**hour urine sample in a apeelally provided lead free flask end analysing the urine for its lead content. If three load urine studies show evidence of increased absorption of lead in the employees, an Industrial hygiene engineering evaluation of the operation should be accom plished in order to detact end control significant lead sources, .'ere a^ain, U/on request, X will also make arrangements for this survey. ~ W. t foam Glass *lant stripping ' paralion.
