Asbestosis is caused by the inhalation of small particles of asbestos. There is apparently some chemical reaction within the lungs to the asbestos as well as an irritating effect by the fibers of asbestos. There are several factors in the development of this disease that should be noted. Of the three common kinds of asbestos available one kind is' much more' toxic than the other two and we do not use the more toxic kind. The size of the fibers inhaled have a definite bearing on how much is inhaled and how far into the lungs these can be breathed. The amount of asbestos in the air obviously affects how much is inhaled; further, the number of hours of ex posure per day will influence how much is inhaled. Another factor we do not have any measurement of is the resistance of any individual that might be exposed. The most common symptom experienced by those people that have been diagnosed as having asbestosis is shortness of breath on exertion. Obviously, this is also a symptom of many other diseases which include not only pulmonary or chest conditions but any systemic illness and especially circulatory illnesses. The second most common symptom is a dry hacking cough. Other symptoms do occur when the disease is more advanced. 2. Can asbestosis be cured; and how? When asbestosis has developed enough to be recognized I do not believe it is curable. By this I mean that I do not believe the asbestos can be removed from the lungs; however, we would certainly not allow any further exposure to asbestos or any other type of pulmonary irritant. This again points to why we are continually monitoring the conditions under which we work and the preventive measures that we have insisted upon such as good ventillation and masks. In this instance prevention is the only cure that is of any great value. % ANSWERS TO QUESTIONS ASKED BY INSUIATORS Page 2 3. Can insulators have more frequent respiratory examinations? If all of our preventive measures are carried out we feel that the frequency of a complete examination and x-ray annually is all that is necessary, but if any one of you has any symptom that you would like to discuss at any time we hope you will do this. The protection of your health is your own personal responsibility first the same as your safety is and I hope that we can be made aware of any conditions that might jeapordize your health immediately when you think such exists. You also raised the question of could you see your x-rays. If any of you as individuals would like to see your x-ray, if you will make an appointment I will be glad to show you your x-ray and interpret it for you. 4. Why did Construction change^from Unibestos to Thermasil? Cost, at the time. This is no longer applicable, and future projects will specify Unibestos. Concerning dust, Thermasil has the smaller particle size. 5. Will Construction quit using Code 502.1 (one-eoat) cement? (Excessive dusting during tear-do .) On future jobs, Johns-Manvil will be specified. #450 cement and #352 (finish coat) 6.- Is Unibestos the safest insulation to use? It is as safe as any on the market today. 7. Will the Company - A. Furnish Insulators coveralls? Only where now furnished (Fiberglas and rotoclone cleaning) B._ Install vacuum system in shops to replace brooms? Further study required, i*-" C. Provide dust collection system for exhaust fan? v Further study required. 1 , D. Put Emiron on floors? Yes, R.O. issued. 4. E. Allow insulators to see their x-rays? / Yes, with Medical help to interpret what they are looking at. F. Have labor group housekeep on large overhaul jobs. (Example* S.M. 15) No, each group housecleans its own job. G. Isolate saws from rest of shop? Yes, with curtain. ANSWERS TO QUESTIONS ASKED BY INSULATORS A Page 3. 8. Why did the Company quit using Air-Cell and Sponge Felt Insulation? Cost. These are not considered safer types, because the particle size in them is smaller. I!. !.

HAYDEN MartinsviJle, Virginia In August. I`)'U, wo began an air sampling program to determine me level ol asbestos dust caused by tin- handling ol asbestos insula tic .. We have used the sampling procedure as recommended by the companywide Asbestos Dust Conference outlined in the ''Asbestos Dust Control" manual. Uu arc using as our sDj^clard for exposure to asbestos fillers the bureau of Occupational Safety & Health Documentation, which states: 'The P.II.S. recommends that occupational exposure-, to asbestos dust be controlled so that no worker shall be exposed to more than 5 asbestos fibers/milliliter based on a count of fibers greater than 5 mm in length as determined by the recommended method, and based on time weighted average exposures for a 40 hour work week. Concentrations greater than 5 Tibers/mlj but not to exceed 10 fibers/ml nuiy be permitted for 15 minute periods in any one hour up to 5 limes daily." from August through November we took 12 air samples on routine work and work which created unusual amounts of insulation dust. These samples were sunt to the University of Pittsburgh Graduate School of Public Health lor analysis. Attached is a summary of the analysis of our air samples. Of the 12 samples, two did not meet the accepted standard. The .job safely writeup fur these jobs has been modified to require the use ol a dust mask. J - K. 11.

Two Plant groups, Insulators ar.d Carpenters, are routinely exposed to asbestos dust particles. To date,, our program to protect these and other employees has been: o Protective Eciuicmcnt for each mail. - Vacuum cleaners - nil shops. - Two special, vacuum equipped, portable work buggies for Insulators. - Exhaust system is provided for all shop powered equipment. - New vacuum system for general housekeeping - main Insulation Shop. 9 Rul?5 aud Procedures - All asbestos scraps must be disposed of in identified poly ethylene bags. - Approximately three air samples per month are made to: Make sure that current safe levels do not become unsafe without our knowledge, o DeU'imino if jobs exceed allowable limits. o Evaluate each hazardous task and try to bring the level of contamination within limits. - In three years of dust sampling, we have exceeded permissible dust limits on five jobs. These jobs Involved fabrication or cleaning and have now been eliminated hv not us inr, a six's cos materials. 1 BI-TT- ASlikhTOS iHim CO'ni'OT. 2- - v - Dust ro.sk is required when: o For for.nine d-.wo!: eicn work a Opes: ..ting 7-.-u" .;v.;s o Cleaning dust ccLlectors or vacuum cleaners c Other jobs ns juig-uent die:'.res - Insulations rust be dampened during demolition to prevent excessive dust. - If applicable, work areas must be roped off and asbestos warning`signs displayed. Any employee entering roped area must wear sane protection as Insulator. - Portable work buggy equipped with vacuum cleaner is used for field fabrication cf fittings. - Vacuum cleaners are used for shop housekeeping (Carpenters may use broom when r.ot fabricating asbestos-containing ma t c?r inis). ^- ^ a Eating and Smoking in l.'ork Areas wk re Asbestos is . Lee - According to the OSHA regulations, eating and sr.uk.ins -`a the asbestos shop is not prohibited if the dust ccr.uuncraties', is less than the allowable standard (5 fibern/cc gtoatur than 5 microns in length). In those plants where local policy prohibits eating ancLsmoking in shuns, there io nu reason not to continue such prirtice. On the other hand, where eating and smoking has traditionally been permitted in shop areas, there is no legal basis for discontinuing the practice, because analyses of our shops indicate we operate far below this standard. Eating is allowed in the main Carpenter Shop, but not in the Insulation Shops because a separate eating .area is available. Smoking, coffee drinking, gum chewing, and snacking are allowed in all shops as long as dust concen tration is kept below allowable standard. e Special Medical Requirements - Annual X-rays and pulmonary function tests arc required of all Insulators regardless of age. To date, all findings arr- negative. - Insulators are allowed to view Lheir X-rays if they so desire. - Comparisons are made between current X-rays and X-rays at hire. To date, findings are negative. Replacement of Asbestos-Containing Materials - Insulation inventories are being replaced and should be complet duringIQ*74. We still expect co purchase "A" cloth, Marinite, asbestos gaskets, and\asbestos packing until such tine as suitable commercial substitutes become available. i , - There is no program planned for wholesale replacement of *' existing, installed, asbestos-containing insulation. However, alterations, repairs (where practical), and new installations will use only asbestos-free materials. .* ASUKNT05 DUST CONTROL -3- 1-YLruary 12, 1974 As a result of the activitii 's outlined above, our primary concerns at this time (subject to. .i:Ht-rnr- tntJ.cn of 'a pjiations) ore: * Legal requirements for pirctoctive clothing. o Legal requirements for dual lechers, change rocir.s, laundering, etc. o Installation of vacuum system in tvo auxiliary Insulation Shops (exhaust syclem ex:Lots in one). We are currently addressing to these and expect decisions by IQ174 The above decisions will undoubtedly be influenced by the fact that in 1976 the permissible asbestos dusr. cor.ccntv.'.iion in the air will be reduced from 5 ft 2 fibers/cc greater than 5 microns in Vn-ib.

Status: Process Hazards Committee Review - Asbestos Following are the recommendations made by the Process Hazards Committee and our status on each: On anv job, where Du Pont provides coveralls, skull caps should also be provided. No asbestos contaminated coveralls or skull cans should be stored in a locker that is used for street clothes. STATUS We currently have approximately 20 pairs of coverhalls that arcavailable for insulators use. It has been our practice to be some what lenient in our approach to providing coveralls. Wo furnish. coverall on some dirty jobs where in our opinion thei'e is no hazard from-asbestos fibers. Coveralls are also furnished for asbestos protection on any job where the urea is roped off, signs ei-eeied, and respirators worn. We feel that the case of asbestos protection is the only time we sho.uld require skull caps. In order to insure that no contaminated coveralls come into contact with street clothes, the following proposal is offered: (1) Purchase an additional 20 pairs of coveralls and 20 skull cans. (2) Purchase a heavy duty washing machine and clothes dryer to be installed in the Insulation Shop for daily laundering. (We now pay $1.00/pair for laundering.) (3) Continue our present practice of providing coveralls. (This, in part, is to avoid a request from Council for 100? coveralls.) Asbestos dust sampling should be the responsibility of the Plant Pollution Control Coordinator, as is the case with other air borne contaminants. Currently, the Insulating Supervisor docs the samp ling. e An interlaboratorv check should be conducted on a regular basis (recommend 2 times/year) to confirm that the contract Laboratory in Richmond that does our analyses is accurate and consistent. STATUS e As soon as George Adams returns from vacation (week of 7/1), we plan to transfer the dust sampling job and inter-lab check tc the Plant Pollution Control Organization.

Martinsville Plant is in compliance with 1910.1001 OSHA standards and Textile Fibers dust exposure guidelines (ref.: J. A. Sigman; June, 1974) B. All asbestos containing materials, except whore no acceptable substitute is available, have been^eliminated from use. C. Insulation shop policy - no smoking, eating, or drinking allowed in Insulation Shop. D. Dustfoe 66, MSA approved, respirators are required on jobs where past experience and/or sampling cheeks have revealed exposure greater tii.m permissible limits. E. Downdraft tables and dust collection facilities provided in all Insulation Shops. F. All damaged (existing) asbestos containing insulation is discarded when removed and replaced with asbestos free (AF) insulation. G. Insulation materials are discarded in accordance with OSHA 1910.1001 paragraph (h) (2) to minimize dusting by sealing in dust-proof con tainers. 11. When working in applicable areas, all outer clothing is furnished .uul laundered by the Company. Dual lockers are also provided to prevent exposed clothing contact with individuals' street clothes. (Ref.: OSHA 1910.1001 (d) (3 & 4). I. Identified wetting procedures, OSHA 1910.1001 (c) (2), are used during removal of asbestos inhibited materials. Communications used to inform those exposed: A. All employees dealing with asbestos are fully aware of hazards and personal protection procedures/equipment. B. Caution signs posted per OSHA 1910.1001 (g) at entrance to each Insulation Shop. J fr C. Each /Insulation worker is given training on the precautions necessary for the protection of this health (i.e., respirator program OSHA 1910.1001 (d) (2) (iv). i1 I). Routine air sample quality chock:; are made to riel on.ii n<- aal'c.a !. p.irlu in breaching air. Insulation employees and/or their representatives are given a reasonable opportunity to observe mouitut iug .mu irview ii-.mU:. >!' dust samples taken. E. All air samples taken in the past two years have not exceeded either OSHA or TF guidelines. Program and timetable for replacement if hazard can be eliminated by use of alternate materials: A. No asbestos containing material is used in new installations with the following exceptions (no acceptable substitute available:): 1. "A" cloth (dustless) 2. Tadpole tape 3. Asbestos thread 4. Asbestos tap'e ^ 5. Asbestos Cubing 6. Tedlar paper 7. Transite ^ Items 1-6 create minimum dust when used. Of all samples taken on Plam involving these materials, none have been over the exposure Limits. Item 7 is used to reinforce the bottom of grid insulation. Fabrication of transice is done by outside contractors. If minor field work is required, OSHA and TF guidelines are followed. B. The following materials are currently under evaluation as per-`acini replacements: - Nomex - phenolic and woven - Fiberglass - Kevlar Although substitutions on low temperature applications are acceptable due to brittleness and wearability. Martinsville has followed other fibers plants lead in using asbestos-free fiberglass and TIW wool ("soft" insula tion) on certain applications. Audit procedures and frequency to determine if proper precautions are being utilized: A. Annual pulmonary checks are made by Plant Medical per OSUA 1910.1001 (j) (3). B. Routine air sample determinations are conducted semi-annually [rei.: OSHA 1910.1001 (f) (2) (ii)__/. Additional checks on infrequent]/ performed or questionable jobs are taken as necessary. C. Additional air sample checks are conducted by other independent Plant groups (i.e.. Plant Environmental). D. Daily safety and housekeeping inspections are conducted on all Insulation Shops and personnel. cc: G. B. Adams n. B. Avrrv T? D.. Barco n. M. Cloud J. ln\ # 1 U1 L .1.* 1I, UT . I?.

SWATS* DISPOSAL 01- ASntlSVQS CONTAINING INSULATION A meeting was conducted on 2/2S/7S, to discuss the disposal oF pipe and vessels covered with asbestos containing insulation. It was determined that our current disposajL procedures (selling pipe and vessels through Salvage without removing insulation or advising buyer oF asbestos hazard) was not in compliance with current OSITA or CPA regulations. Therefore, the foilwing procedures will be implemented immediately until a suitable disposal procedure can be Found; Salvage (J. B. Lamkin) will designate and rope-off an area as a collection point for pipe and vessels covered with asbestos containing insulation. Warnings will be posted as necessary to advise personnel of the asbestos hazard. All pipe and vessels covered with asbestos containing insulation will be removed in accordance with WEP E/j - 623, tagged with an asbestos caution tag (form G-322, Stores Item No. 14418), and sent to Salvage. Pipe covered with asbestos containing insulation will not be placed in scrap hoppers; it will either be delivered to Salvage or placed on a pallet for pick-up by a Salvage operator. J. B. Lamkin and D. L. Swats respectively will contact the Surplus Material Division and the Division Engineer's office for additional guidance on proper disposal procedures. *Attended meeting. __ J s. TO: B. M. CLOUD FROM: D. L. SWATS^ DISPOSAL OF ASBESTOS CONTAINING INSULATION (Ref: Letter, dated 3/3/7K) J. B. and I respectively contacted the Surplus Material. Division and the Division Engineer's office for additional guidance on proper disposal procedures for pipe and vessels insulated with asbestos con taining insulation. Both offices recommended removal of all asbestos containing materials prior to sale, or disposal in accordance with procedures for asbestos containing materials. We feel the least expensive method will be to have contractors (BWB) remove the insulation, then sell the uncovered pipe and vessels. J. B. is scheduling a meeting with Jerry Cummings to discuss this proposal. We are currently following the procedures outlined in referenced letter; however, to date. Salvage has only received four steam chests which are covered with asbestos containing insulation. Therefore, we do not believe that removing the insulation prior to sale will have much impact. I will keep you advised as to how we resolve the disposal problem. DLS/hh cc: M. Cloud A. Ferrante rn Griffin F. Hesselberth W. HH. G. Kouk C. C. Smith K. W. Stueber H. ?. Varn R. M.

YATES (3) US% OF ASBESTOS MARTINSVILLE PLANT STATUS In order to minimize personnel exposure, the use of asbestos containing materials has been discontinued where acceptable substitutes are available. As a result, no asbestos containing material is now being used in new installations with the followinc exceptions: Pump and valve packing Gasket material Brake linings' Generally speaking, these items are asbestos impregnated and are therefore unlikely to present a health hazard. "However, handling of these items can cause asbestos fibers to become dislodged over a period of time. Therefore these items should be stored in a manner that prevents the accumulation of asbestos containing dust. For example, a peg board is an acceptable method for storing gaskets. If the material must be stored in a drawer or bin, it should be placed in a plastic bag. The storage place should be cleaned periodically to prevent dust buildup. Of course, existing asbestos insulation is in place all across the site. Attachment I is a listing of these installations. Each area should inspect their asbestos insulation for conditions which could lead to employee exposure to airborne asbestos fibers 2 (i.e. badly damaged insulation). Conditions needing repair should be reported to J. W. Cobler, Insulation Supervisor, ext. 2781. Jimmy can also help identify asbestos. Obsolete asbestos materials should be discarded and good housekeeping maintained in storage areas. Asbestos containing materials should not be stored with respirators, respirator filters , food, gum, cigarettes or any other item which may be placed in the mouth.

WATLINGTON J. M. YATES (3) CONTROL OF ASBESTOS MATERIALS On recent audits observations of exposed damaged insulation and asbestos gloves available for use have pointed out the need to review control of asbestos materials throughout the plant. It has been plant policy to eliminate the use of asbestos insulation and other asbestos containing products which could release fibers during normal use or disposal. Currently, the only permissible asbestos containing materials now in use for new installations are: pumps and valve packing gasket material brake linings These items are asbestos-impregnated and thereby unlikely to present a health hazard. However, handling of these items can cause asbestos fibers to become dislodged and therefore should be stored in a manner' that prevents the accumulation of asbestos containing dust. * A peg board is an acceptable method for storing gaskets but if asbestos material is stored in a drawer or bin, it must be placed in a plastic bag. The storage place should be cleaned periodically to prevent dust buildups. 2 Asbestos containing materials must not be stored in the same cabinet or drawer with food, gum, cigarettes or any other items which come in contact with the mouth. In addition, asbestos containing materials will not be stored with respirators or respirator filters. Permanent asbestos insulation is still in place across the plant. Each area should inspect their insulation for conditions of badly damaged insulation which could lead to employee exposure to airborne asbestos fibers. Conditions needing repair should be reported to the Insulation Supervisor on ext. 2781. He may also be helpful in identifying questionable materials containing asbestos and the .safe disposal of such material. The attachment lists those items across the plant which contain asbestos material. It is suggested that each area review this list to make sure it is correct and all other asbestos containing materials have been eliminated. If any items have been eliminated or replaced with asbestos free material or you have questions on asbestos, contact the writer on ext. 2302.
