Viera, 2000/3201 (511) SUBJECT: Safety Alert - Hav 27. 1987 1 have read your "Safety Alert" and do not agree with your statement that "the enclosures [built for work on asbestos containing materials] are confined spaces and need to meet your location [confined space] requirements." The enclosure may or may not have to be treated as a confined space based on each specific case. If the enclosure were In a pit deeper than 4 feet, or within a room/area previously designed as a confined space, etc.. It would be a confined space under the existing "confined space" definition. One must realize that whenever you build any type of enclosure within a chemical plant you must be cognizant of the fact that a hazardous atmosphere may be created Instantaneously (release of a safety relief device, flange rupture, etc.) or slowly over time (such as minor leak, disturbing flammable/toxlc materials within the enclosure, etc.). Thus, creating an asbestos removal enclosure In a unit must be very carefully thought out and safety reviewed by competent Individuals. In all cases, I have highly recommended to our POD location safety and health managers (unless of course the enclosure has been designated a confined space and then the full confined space entry requirements must be met) that: UCC 011407 BUSINESS L. . Calvert CONFIDENTIAL -2- June 3, 1987 1. Prior to each dally entry Into a negative pressure enclosure and each time It Is reentered after 'breaks" and periods following blower shutdown that LEL, oxygen, and toxicity (If warranted) tests be taken to assure entry is being made Into a safety atmosphere. 2. Each Job requiring the use of a negative pressure enclosure be carefully evaluated, and where the enclosure encompasses a known potential hazard such as a vent, safety relief device, etc., that continuous LEL/O2 monitoring be conducted. [Note: Ue do not require a standby attendant, emergency equipment, etc., that are required by the "Confined Space Policy".] Again, to reiterate. It Is my contention that not alj. asbestos removal negative pressure enclosures are confined spaces by definition as your safety alert Infers. They may or may not be confined spaces based on their physical location or construction characteristics. Considering the aforementioned, I would recommend that you Immediately clarify this "confined space" misconception with the recipients of the Safety Alert, especially the location Maintenance Department Heads. The Safety Alert as written appears to establish a C&P standard namely, all negative pressure enclosures used In the asbestos removal process are confined spaces. At best. It could be causing confusion at the location (Maintenance Interpretation versus Safety Group Interpretation), and at worst. It could cause a plant to unnecessarily receive an OSHA citation and spend time on subsequent litigation. Should you have any questions on this subject, please give me a call.

FEY RtCEIVtD MAy 4 1987 L L COL^S To: See Attached Distribution List Copy to: See Attached Distribution List t Subject: Asbestos Gasketing and Packing Rapid changes in the asbestos area are taking place and the rate of change will probably stay high until the majority of asbestos is replaced. This communication is an overview of current activities to help you meet regulatory requirements. A task group (C. Neely, et al) dealing with the phase-out of asbestos containing materials in the work place for C&P, made their recommendation to the Manufacturing Council via B. G. Perry, and it was approved in March, 1987. (Recommendation attached) A key recommendation was termination of purchase of asbestos containing materials7~ifter January 1, 1987. ' During the development of the original recommendation, the supply world has changed. UCC's three major suppliers are no longer manufacturing asbestos containing materials. No supplier is willing to make a firm commitment to supply asbestos containing materials after the end of 1987, because of the inability to get liability insurance. In addition, the cost of asbestos has gone up 2556 in the last twelve months. Therefore, the recommended deadline for purchase cessation may be met by lack of supply. - continued UCC 011409 -2 In order to help prepare for this change-over, the following actions are in progress: 1. The task force has initiated and expedited actions to do the engineering specification work for asbestos replacements for gasketing and packing. These C&P Engineering Standards will be available for each location by September, 1987. Specific questions before then should be discussed with Rex Engle at the South Charleston Tech Center. Manufacturing Services - Maintenance working with UCC Carbon Products and Texas City Plant Maintenance is developing a video tape of "How-To's" for Grafoil , installation in gasketing and packing applications. This videotape will be available thru Manufacturing Services - Maintenance in June, 1987 and you will be notified later how to obtain it. The videotape is designed to simplify the work of training your people. In addition to the use of the videotape, it would be wise to contact Jim Polomsky of Carbon Products to provide further follow-up, Hands-On Training. (713+852-9468 - Home - Houston, Texas or 1-800-822-4322 - Office - Cleveland, Ohio). See attached seminar content defail. 3. Exposure level data for situations of removing, cutting, and handling gasketing and packing is now being collected from several locations by Industrial Hygiene. With these data, the appropriate removal methods can be specified. Industrial Hygiene coordination of this data collection program should eliminate the need for each location collecting data. 4. We are representing maintenance for all C&P locations in the on-going review of the OSHA field compliance Instructions Draft. As conclusions are drawn we will let you know. We are coordinating these efforts In order to speed communications and minimize the efforts for each location. For further assistance, please call Ashton Barefoot at UNICOM 529-6437 or 713+486-6437.

Neely SUBJECT: Final Draft of Recommended C&P Program Phase-Out Use of Asbestos-Containing Materials In Work Place Chemicals and Plastic Group Attached herewith on behalf of the Special Working Group Is a copy of the subject document dated 9/29/86. It Is a slightly fine-tuned version of the 8/2B/86 version which was transmitted to you under my transmittal also dated 8/28/86. The changes that have been made are of a clarifying rather than substantive nature. At this point, we have not made an effort to obtain broad, formal review of the subject program. However, Larry Calvert has discussed It briefly with the Maintenance APK*ls and Maintenance Managers. In addition, Stan Clark arranged for Its review by the Safety, Health Advisory Committee (SHAC), and your staff has reviewed It. Feedback Indicates these groups to be supportive of the concept, but some have expressed concern regarding the January 1, 19B9 date specified for the discontinuance of the purchase of asbestos-containing materials, believing It to be optimistic. Some of the concern relates to the following: 1. CED's ability to revise and reissue the ViP Specifications and the Valve Manual In time to support the deadline. The responsible CED specialists have carefully reviewed this matter and believe that reissuance of these Manuals by July 1, 19BB Is realistic. This date has not been published, however. UCC 011412 Hr. J. E. Sanders -2- September 30, 1986 2. Belief that field testing of new gasket and packing materials will be required. Such testing will not be necessary since the plan at this time Is to accommodate most of the substitutions by broadening the use of materials already In use, materials such as reinforced Teflon and GRAFOIL". This plan has not been broadly disseminated, and we can fully appreciate the reluctance to agree to a purchasing cut-off date for asbestos-containing products without knowing what the substitutes are. We also appreciate that, once this material substitute plan Is known, there will be a natural resistance due to the higher first cost of these substitute materials. 3. Some belief that Installers will need special training to handle the new gasket and packing materials. For reasons cited In (2), we do not believe this requirement will be significant. , 4. Perhaps lack of understanding that the January 1, 1989 date Is the cut-off date for the purchase of asbestos-containing materials except as approved by a variance. 5. "Is this really necessary" attitude. The Special Working Group believes that OSHA's recently revised exposure limit of 0.2 fibers per cubic centimeter of air (was previously 2.0 fibers per cubic centimeter) add significant Impetus to Implement the proposed Recommended Program. According to Terry Hanning's September 5, 1986 memorandum (copy attached), labor union representatives do not believe that controlling the exposure limit to this lower level provides adequate protection. The above concerns notwithstanding, the Special Working Group decided to submit the subject Recommended Program to you with the January 1, 1989 date Included since we believe that, with proper communication with the key plant personnel responsible for Its Implementation, along with management support, this date Is realistic and achievable. We are submitting under separate cover a proposed CED Technology Program which Includes request for funds to cover the Important communications aspect of the understanding, acceptance and Implementation process. Please let me know how we can be of further assistance regarding this matter. CCN:mr 43191 Attachment UCC 011413 8/28/86 0RAFT RECOMMENDED POLICY CHEMICAL AND PLASTICS BUSINESS GROUP (C&P) SUBJECT: USE OF ASBESTOS-CONTAINING MATERIALS^)lN THE WORK PLACE PURPOSE/BACKGROUND The Corporate Charter (1.1) contains the following commitment to employees: "To provide working conditions, programs of training and education, and persistent review and appropriate modifi cation of facilities and practices to protect the health and safety of employees." / It also contains a social commitment to conduct business "In accordance with all the applicable national and local laws and regulations." As a result of available evidence that airborne asbestos In the occupa tional environment had proven to be carcinogenic In man, all C&P Insulation Standards were revised In 1976 to specify only asbestos-free Insulating materials; and new or replacement Installations of these materials have sub sequently been selected accordingly. Additionally, a Safety/Health Standard designated SH-256 was prepared covering the safe removal and handling (In cludes disposal) of asbestos-containing insulating material during renova tion and demolition. The requirements of this Standard equal or exceed those of current applicable government standards. OSHA's rule-making efforts relative to asbestos usage In the work place are mired In controversy. Hearings on the latest EPA proposal which In cludes the phaseout of all asbestos over a ten-year period are now In prog ress. The proposal states: "EPA Is considering banning the manufacture. Importation, and processing of asbestos construction products and asbestos clothing soon after the rule's promulgation with the category of asbestos friction products banned about five years later, and other asbestos products banned at a later time." Gaskets and packing that contain asbestos are In the category of "other asbestos products" that would apparently be banned after ten years. No peer company that we are aware of has a target date for removal of existing asbestos-containing Insulation, gaskets, or packing; however, one major chemical company has recently discontinued the purchase of asbestos-containing gaskets and packing. A cost analysis of pipe-size gaskets shows that GRAFOIL*, probably the most expensive of the acceptable gasket substitute materials. Is, In fact, cost effective when only the cost of mandatory work practices associ ated with the use of asbestos (e.g. wetting for removal or airborne fiber (11"Asbestos-containing materials* Include but are not limited to Insulation, gaskets, packing, welding blankets, and building materials. UCC 011414 DRAFT 2- - 8/28/86 exposure monitoring during removal, placing In labeled plastic bags after removal, landfill disposal, and record keeping) Is considered. The same conclusion Is drawn relative to valve packing when the additional considerations of Improved service life and sealablllty are Included. Consistent with the aforementioned commitments and the economic use of materials, C&P has concluded that positive actions relative to asbestos-con taining materials^) should be taken. POLICY Except as otherwise provided by applicable law. Chemicals and Plastics Business Group will: f Continue to phase out the use of asbestos-containing materials: Asbestos-containing Insulation shall be replaced with asbestos-free materials as required to maintain structural and functional Integ rity. No asbestos-containing materials shall be purchased after January 1, 1989. C&P approved practices shall be ..employed for the Identification, removal, modification, and/or disposal of asbestos-containing mate rials. Evaluation of asbestos substitute materials shall Include considera tion of health effects as well as suitability for Intended service and cost. A variance approval procedure shall be employed to cover considera tion of uncommon circumstances. Approval must always Include en dorsement of C&P HS&EA management. SCOPE This recommended policy applies to all C&P operated/hosted facilities. Other components of the Corporation will be apprised of Its content. DELEGATION The assignment of duties and authority to carry out the policy defined herein Is delegated as follows: To Central Engineering Department Develop and maintain engineering standards covering: - Identification of asbestos-containing materials; UCC 011415 D RAFT 8/28/86 -3- - Removal, modification and/or disposal of asbestos-containing mate rials; and - Use of asbestos-substitute materials.

By itself, GRAFOIL flexible graphite seals about as readily as rubber. It is also fabricated into metal core laminates or into spiral wound gaskets, and significantly improves their characteristics. In general, GRAFOIL gaskets will seal the maximum pressure specified on properly designed, correctly manufactured and suitable maintained equipment. While being flexible and resilient, GRAFOIL flexible graphite is still all graphite. It has no resins, binders or filler materials or other additives that might detract from the chemical inertness and temperature resistance of pure graphite. GRAFOIL gaskets will not cold flow, become brittle, or vulcanize to gasketing surfaces in service. The unique chemical and physical properties of GRAFOIL flexible graphite combine to make it a nearly universal gasketing material especially suitable to high temperature and cryogenic service and|or corrosive environments. GENERAL POINTS TO REMEMBER WHEN GASKETING WITH GRAFOIL FLEXIBLE GRAPHITE 1. ) Ine flange surfaces must be clean, free ofnicks, scratches, burrs, metal fillings, scale or other foreign matter. 2. ) Use a proper bolt tightening sequence to ensure a uniform load is applied to the joint (see Figure VI). The use of a torque wrench is advantageous to ensure that a uniform tensile stress is applied to each bolt. 3. ) GRAFOIL Grade GHE 316 Stainless Steel Tang Metal Inserted gaskets (Catalog Section G-8B17 and G-8819) should not be used between any metal surfaces that are softer than the stainless steel (i.e. aluminum, brass, bronze), or between glass or ceramic surfaces. When GRAFOIL Grade GHE gaskets are used, the metal tangs must be compressed such that the GRAFOIL begins to seal. Due to the minimum seating stress recommended for these gaskets (i.e. 2500 psi), the metal tangs can-make small indentations in the softer metal of the flange face. The tangs can also create stress concentration points on glass or ceramic surfaces. 4. ) GRAFOIL flexible graphite gaskets must be loaded with a net compressive unit load as shown in the Unit Load vs. Leak Pressure Curve, Figure I, and in GRAFD2L Catalog Sections G-8816 and G-8817. 5. ) The initial thickness of the GRAFOIL gasket must be such that when it is compressed between two mating surfaces, the GRAFOIL is strained sufficiently at all points in the joint to seal the maximum service . pressure. If the flange surfaces are scratched, serrated, or warped, the initial gasket thickness must be large enough to completely fill and compensate for their effects when - the joint is made and the gasket is compressed. PO Box M637 UNION CARBIDE CORPORATION OniO^-itOT flerww (031622-4323 inOno I?16| 539 2900 TELEX 81P-C21 0CU7 UCC 011418 S^iOO? ^meOmU.S * 6.) The flatness of the flange surfaces is as essential to good gasketing practice as the proper gasket unit load. If gasketed surfaces are perfectly flat under operating conditions, the average unit load is also the minimum unit load. If, for any reason the gasketed surfaces are not flat while in service, the gasket unit load can be less at some point or points than the amount required to seal operating or test pressures. In general, if when the flange faces are brought together (i.e. just touching and under no bolt load), a 0.001" feeler gauge can not be inserted anywhere around the circumference of the joint, then a 1(64 inch (0.015") thick GRAF0IL gasket can always be used. If this criteria can not be met, then the thicker GRAF0IL gasket will be required. IMPORTANT POINTS CONCERNING FLANGE SURFACE FINISH AND "STANDARD11 SERRATIONS Under equivalent compressive unit loads, GRAF0IL gaskets will seal w^ere surface finishes range from 5 RMS (root mean square) to 125 RMS. Within tha,t range any RMS finish will seal as well as any other. Flanges ordered with "standard serrations" or a "standard finish" usually have finished surfaces machined in accordance with MSS Standard Practice SP-6 (1) which allows for considerable latitude in finish. The SP-6 Standard refers to AARH finishes or arithmetic average roughness. AARH values are different from RMS valves for any given surface. RMS measurements can be made with stylus tracer instruments, whereas, AARH can not. AARH finishes are evaluated only by "sight and touch" comparisons with standard specimens. The standard serrations may be concentric or spiral. If concentric, there may be up to 32 serrations per inch, and the depth of the serration may range from 0.005" to 0.015". The serration cross-section can range from a radiused "u" cut to a "v" cut. Flange surfaces having the maximum serrations per inch at maximum depth can leave a "saw tooth" surface with little or no flat areas between the serrations. GRAF0IL flexible graphite gaskets a re not recommended for use with this type of flange finish. Spiral serrations can range from 20 to 50 per inch in number and from 0.001" to 0.006" in depth. Again, the maximum number of serrations to maximum groove depth can produce a sharp, "saw tooth" surface. However, in contrast with concentric serrations, a spiral serration can form a continuous leak path if the gasket material does not deform and .seal all the way to the bottom of the groove. Consequently, the greater the depth of the spiral serration, the greater the required thickness of the GRAF0IL gasket in Drder to seal. The required thickness can be calculated in a manner similar to that shown in Case 3. While serrations, in general, do not help GRAF0IL gaskets to seal, GRAF0IL gaskets with their unique physical properties will seal serrations more dependably than most other materials. If a flanged joint is being designed with the intent of using GRAF0IL flexible graphite gaskets, it is recommended that the serrations and surface finish be dimensioned in detail, rather than left to the broad limits permitted by Standard Practice SP-6.

A C3 homopolymer, C2/C3 random copolymer and a C2/C3 impact copolymer will be made. The catalyst is predominantly titanium trichloride and the cocatalyst is a mixture of diethylaluminum chloride (DEAC) and ethylaluminumdichloride (EADC) as a 20% combined solution in isopentane (will be purchased premixed from Texas Alkyls). Nitrogen will be the carrier gas for the catalyst slurry.We may dilute the alkyl solution some more with isopentane if needed for metering purposes. Reaction conditions will be very similar to current SHAC-103/201 runs, with hydrogen used for molecular weight control and nitrogen for inerting, blowbacks, etc. No unusual operating conditions will be employed and all current standard operating procedures for polypropylene will be followed. Standard polypropylene analytical support will be needed. HEALTH AND SAFETY: MSDS sheets for the two raw materials ara^attached. The catalyst slurry will be handled the same as our/SHAC catalysts. The health and safety considerations are the same/though it will react faster to give off more HC1 than SHAC. It is not oyrophoric ,, it can be disposed of via the same procedure as our SHAC catalysts, although we don't intend to throw/fl^of this catalyst* We will receive the catalyst both in slurry and in dry form. We intend to use the slurry and save the solid for contingencies such as making up more slurry. If this is necessary we can handle these in the drybox the same as we do when making SHAC catalyst slurries. We have handled DEAC before, and the DEAC/EADC solution will be treated per our normal alkyl handling procedures. There is no unusual health or safety considerations. These materials can be disposed of via the waste alkyls tank per the waste disposal SOP . The DEAC/EADC forms some associative species when combined but we are not doing the mixing and these,would not change the safety aspects of handling. S\e,\u> Any unwanted resins which are produced as part of this experimental program can be put to the scrap resin gaylords. PROCEDURE: The 3 runs will be made via our standard run plan which gives the process conditions and MSDS sheets. There are no changes in equipment or standard operating procedures. Our slurry feeder and alkyl feed system will be used as is, though the slurry feed rates may be higher. D. J.

This aspect of organoaluminum chemistry has been studied thoroughly,J-45J'60. In general, trialkylaluminum compounds exist as dimers associated through electron deficient bondinig6': R`^ /R\ X R R RR If the alkyl groups possess steric bulk, e.g., isobutyl or neopentyl, the trialkylaluminum compound exists in monomeric form. Dialkylaluminum hydrides are trimerically associated through hydride bridges as below. In contrast to R3AI compounds, association of RR Al HH R Al R- R R R2AIH compounds is insensitive to steric require ments of the alkyl groups. Alkylaluminum halides are strongly dimeric, bridging through the halogen atoms as below. An alkylaluminum sesquihalide is essen tially a 1:1 complex of R*AIX and RAIX2 compounds. /X\ >R RX Association in the vapor phase is a property that affects latent heat values. Empirical equations (Othmer, Ctausius-Clapeyron) are used to estimate employing molecular weight values of the associated species (see Table 2, page 8). -.Al / xXB v x^ ^X Al\ A RX Alkylaluminum alkoxides are associated as dimers, trimers or tetramers depending on the nature of the alkyl and alkoxyl groups.
