Your response will be used to formally address this concern as stated on page 2 of Attachment A, Phaseout Use of Asbestos-containing Materials in Work Place, issued by Mr. J. E. Sanders on January 6. Please answer the following questions and send your responses to me by April 8. 1. Do you have industrial hygiene monitoring data for field exposure during the cutting or removal of asbestos-containing gaskets or packing? If yes, were employees overexposed with respect to the OSHA action level or permissible exposure limit on an eight hour time -weighted average basis? If no, do you have plans to gather such monitoring data? 2. Does your location have a written maintenance procedure describing the proper methods for the cutting or removal of asbestos-containing gaskets or packing? If yes, what type of abatement methods are required when cutting or removing asbestos-containing gaskets or packing? If no, do you anticipate an active role in developing such a procedure with your maintenance department? / t ~~t- UCTC 16966 PLAINTIFF'S EXHIBIT 4 Page 2 3. Is it a practice at your location to wet and/or use glove bags before cutting or removing asbestos-containing gaskets or packing? 4. What is your professional opinion on the need for personnel protection-during the cutting or removal of asbestos-containing gaskets or packing? DISCUSSION The Manufacturing Council has accepted a proposal by the Asbestos Phaseout Task Group to discontinue the purchasing of asbestos-containing materials after January 1, 1989. Gasketing and packing have been identified as the high-priority issue since the purchasing of asbestos-containing insulation has been discontinued since 1976. The Task Group is currently studying the need for development of a personnel protection policy when cutting or removing asbestos-containing gaskets and packing. As a reference for this study. Appendix G of 29 CFR 1926.58, OSHA's final rule for exposure to asbestos fibers in the construction industry, is included as Attachment B. This appendix is considered non-mandatory when employers choose to comply with all of the requirements of 1926.58. However, it is mandatory when employers wish to be exempt from paragraphs (e)(6) and (f)(2)(ii)(B) of 1926.58. These paragraphs normally require negative-pressure enclosures and initial monitoring when the exposure of workers to concentrations of asbestos fibers may exceed the action level. When employers choose to follow Appendix G during small-scale, short duration renovation or maintenance tasks involving small-amounts of asbestos-containing materials, the requirements for negative-pressure enclosures and initial monitoring are replaced with other abatement methods. These include the use of glove bags, specific methods for the removal of an entire asbestos-covered pipe or structure, and the construction of mini-enclosures. Whenever feasible, and regardless of the abatement method to be used (e.g. . removal, enclosure, use of glove bags). Appendix G requires wet methods during small-scale, short duration activities. Handling asbestos materials wet is one of the most reliable methods of ensuring that asbestos fibers do not become airborne and hazardous. Sincerely, 6*. TEH Terry E.

In an effort to address the Implications for Chemicals and Plastics concerning the continued use of asbestos-containing materials In the work place, the Manufacturing Council requested that a Task Group be appointed to evaluate the Issue and to recommend a course of action for Chemicals and Plastics. The key recommendation In the Task Group proposal to the Manufacturing Council was that no asbestos-containing material be purchased after January 1, 1989. The recommendation was accepted and the Task Group was then chartered to develop Implementation plans. It Is Important to note that neither the Task Group nor the Manufacturing Council recommend retrofitting, unless the structural Integrity of the asbestos material had been compromised; the plan Is to discontinue purchasing only. Early work by the Task Group Identified gasketing and packing as the high-priority Issue since the purchase of asbestos Insulation had already been discontinued. The Task Group determined that UCC's GRAFOILTM to be the designated replacement for asbestos-containing gaskets and packing In most applications. It Is recognized that GRAFOILTM has a higher Initial cost; however, when disposal costs alone are considered, asbestos-containing gaskets and packing cost Union Carbide considerably more than the GRAFOIL1" counterparts. / UCTC 16968 J >> A. S. Amatangelo, et al January 6, 1988 Page Two The handling costs of asbestos-containing products have been significantly affected by the June, 1986, OSHA ten-fold reduction In allowable exposure levels from 2 flbers/cc to 0.2 flbers/cc, with an action level of 0.1 flbers/cc. At the request of the Task Group, work Is under way to determine If personnel protection Is required when cutting or removing asbestoscontaining gaskets and packing. The Piping Technology Skill Center In Central Engineering Is In the process of revising the Valve and Piping Specifications to' reflect the change to GRAFOIL" products. Revisions are currently being Issued, and by early In 1988, all Valve and Piping Specifications revised to Identify the replacement GRAFOIL"1 gaskets and packing will be Issued. Thus at this time, each location will have the needed Information to develop a plan to completely phase out the use of asbestos-containing gaskets and packing. In this period of transition, locations will need to train their people In the use and Installation of GRAFOIL" gaskets and packing. To achieve this most efficiently, they can use a videotape prepared by the UCC Specialty Products Group, Carbon Products, for use In training Installers. Karl Schmidt (216-529-3902) In Specialty Products, Cleveland Office, can provide Information and assistance. The Task Group has now turned Its attention to Identifying asbestoscontaining products other than gaskets and packing. As the work of the Task Group progresses, we will keep you Informed. Feel free to contact any one of the members for more Information or further discussion. Team UNICOM Function C. C. Neely L. E. Calvert S. W. Clark G. B. Elder R. W. Engle T. E. Hanning M. E.

As discussed in the Summary' and Explanation section of the preamble for paragraph (g). Methods of Compliance, wet methods can be used in the great majority of workplace situations. Only in cases where asbestos work must be performed on live electrical equipment, on live steam lines, or in other areas where water will seriously damage materials or equipment may dry removal be performed. Amended water or anolher welting agent should be applied by means of an airless sprayer to minimize the extent to which the asbestos-containing material is disturbed. Wei methods; Asbestos-containing materials should be Removal methods wetted from the initiation of the maintenance or renovation operation and wetting agent? should be used continually throughout the work period to ensure that any dry' asbestoscontaining material exposed in the course of the work is wet and remains wet until final disposal. Removal ofSmall Amount of AsbestosContaining Materials Several'methods cab be used fo remove small amounts of asbestos-containing materials during small-scale, short-duration renovation or maintenance tasks. These include the use of glove bags, the removal of an entire asbestos-covered pipe or structure, and the construction of mini-enclosures. The procedures that employers must use for each of these operations if they wish to avail themselves of the final rule's exemptions are described in the following sections. Clove Bags As discussed in the Summary and Explanation section of the preamble for paragraph (g). Methods of Compliance, evidence in the record indicate that the use of glove bags to enclose the work area during small-scale, short-duration maintenance or renovation activities will result in employee exposures to asbestos that are below the final standard's action level of o.l f/cc This appendix provides requirements for glovebag procedures to be followed by employers wishing to avail themselves of the standard's exemptions for each activities. OSHA has determined that the use of these procedures will reduce the 8 hour time weighted average (TYVA) exposures of employees involved in these work operations to levels below the action level and will thus provide a degree of employee protection equivalent to that provided by compliance with all provisions of the final rule. Clave Bag Installation. Glove bags are approximately 40-inch-wide times 64-inchlong bags fitted with arms through which the work can be performed (see Figure G-t(A)|. When properly installed and used, they permit workers to remain completely isolated from the asbestos material removed or replaced inside the bag. Glove bags can thus provide a flexibile, easily installed, and quickly dismantled temporary small work area enclosure that is ideal for small-scale asbestos renovation or maintenance jobs. / UCTC 16971 ( *23786 / Fetferal Register / Vol. 51, .Na. 119-/ Friday; June 20. 1986 / Rules and Regulatipns , . bag is attached to the pipe by folding the open edges together and securely sealing d them with tape. AH openings in the glove bag must be scaled with duct tape or equivalent material The bottom seam of the*glove bag must also be sealed with duct tape or equivalent to prevent any leakage from the .bag that may result from a defect in the bottom {Figure G--1(B)).

(3)The removed asbestos material from-the ` pipe oc other surface that has fallen into the enclosed bag must be thoroughly wetted with a wetting agent (applied with an airiest ,. sprayer through the pre-cut port provided in most gloves bags or applied through a small hole cut in the bagl (Figure G-t(C)). (4) Once the asbestos material has been thoroughly wetted, it can be removed from the pipe, beam or other surface. The choice of tool to use to remove the asbestos-containing material depends on the type of materiaFto 5 j ^ be removed. Asbestos-containing materials i are generally covered with painted canvas and/or wire mesh. Painted canvas can be-eut with a razor knife and peeled away from the asbestos-containing material underneath. Once the canvas has been peeled away, the asbestos-containing material underneath ma> be dry. in which case it should be re-sprayed with a wetting agent to ensure that it generates as little dust as possible when removed. If the asbestos-containing material is covered with wire mesh, the mesh should be cat with nips, tin snips, or other appropriate tool and removed. Flgun G-t. Diagram.

Glove Bag Work Practices. The proper use of glove bags requires the following s;eps: (1) Glove bags-must be installed so that ' they completely cover the pipe or other structure where asbestos work is to be done. Glove bags are installed by cutting the sides of the glove bag to fit.the size of the pipe from which asbestos is to be removed.

Such an enclosure should be constructed of 6-mil- thick polyethylene plastic sheeting and can be small enough to restrict entry to the asbestos work area to one worker. For example, a mini-enclosure can be built in a small utility closet whea asbestos- containing duct covering is to be removed. The enclosure is constructed by: (l) Affixing plastic sheeting to the walls with spray, adhesive and tape: - (2) Covering the floor with plastic and scaling the plastic covering the floor to the plastic on the walls. (3)-Scaling any. penetrations such as pipes or electrical conduits with tape: and (4) Constructing a small change room (approximately 3 feet square) made of 6-mil* thick polyethylene plastic supported by 2.fnch by 4-iach lumber (the .plastic shoujd be . ' attached to the lumber supports with staples or spray adhesive and tape). . The'change room should be contiguous to the mini enclosure, and is necessary to allow the worker tovacuum off his protective coveralls and'remove them before leaving the work area. White inside the enclosure, the worker should 'wear Tyvok4- disposable coveralls and-use the appropriate HEPA . filtered dual cartridge respiratory protection. The advantages of mini-enclosures are that they limit the spread of asbestos contamination. reduce the potential exposure of bystanders and other workers who may be working inadjacent areas, and are quick and easy to instaUL The disadvantage of mini enclosures is that they may be too small to contain the equipment necessary to create a negative pressure Within the endosure: however, the double layer of plastic sheeting will serve to restrict the.release of asbestos fibers to the area outside the enclosure. Removoi ofEntire Structures When pipes are insulated with asbestoscontaining materials, removal of the entire pipe may be more protective, easier, and more cost-effective than stripping the asbestos insulation from the pipe. Before such a pipe Is cut the asbestos-containing insulation must be wrapped with 6-mil polyethylene plastic and securely, sealed with duct tape or equivalent This plastic covering will prevent asbestos fibers from becoming airborne as a result of the vibration created by the power saws used to cut the pipe. If possible, the pipes should be cut at locations that are not insulated to avoid disturbing the asbestos. If a pipe is completely insulated with asbestos-containing materials, small sections should be* stripped using the glovebag method described above before the pipe is cut at the stripped sections. Enclosure The decision to endose rather than remove asbestos-containing material from an area depends on the budding owner's preference, i.e- for removal or containment. Owners consider such factors as cost effectiveness, the physicat configuration of the work area, and the amount ef traffic in the area when determining which abatement method to use. If the owner chooses to endose the structure rather than to remove the asbestoscontaining material insulating it a solid structure (airtight watls and ceilings) must bo built around ike asbestos covered pipe or structure to prevent the.release of asbestoscontaining materials into the area beyond the. enclosure and to prevent disturbing these * Mention of trade names or commercial products does not constitute endorsement or rtrcommendation for c$e.

Such a permanent {ic.. for the life of the betiding) enclosure should be built of new construction materials and should be impact resistant and airtight. Enclosure walls should t>e made of tongue-a;d-gr<>oee boards, boards with spine joints, or gypsum hoards having taped seams. The underlying structure must be able to support the wcigftt of the enclosure. (Suspended ceilings with laid in panels do not provide airtight enclosures and should not be used to enclose structures covered with asbestos-containing matenals.) All joints between the walls and ceiling of the enclosure should be caulked to prevent the escape of asbestos fibers. During the installation of enclosures, tools that are used (such as drills or rivet tools) should be equipped with HEPA-filtered vacuums. Before constructing the enclosure, all electrical conduits, telephone lines,, recessed lights,, and pipes in the area to be enclosed should be moved to ensure that the enclosure will not have to be re-opened later for routine or emergency maintenance. If such lights or other equipment cannot be moved to a new location for logistic reasons, or if moving them will disturb the asbestos-containing materials, removal rather than enclosure of the asbestos-containing materials is the appropriate control method to use. Maintenance Program An asbestos maintenance program must be initiated in all faculties that have asbestoscontaining materials. Such a program should include: Development of an inventory of .til asbestos-containing materials in the facility; Periodic examination of all asbestoscontaining materials to detect deterioration; Written procedures for handling asbestos materials during the performance of smallscale. short-duration maintenance and renovation activities: Written procedures for asbestos disposal: and Written procedures for dealing with asbestos-related emergencies. Members of the building's maintenance engineering staff (electricians, neating/air conditioning engineers, plumbers, etc.) who may be required to handle asbestoscontaining materials should be trained in safe procedures. Such training should include at a minimum: Information regarding types of asbestos and its various uses and forms: Information on the health effects associated with asbestos exposure: Descriptions of the proper methods of handling asbestos-containing materials; and Information on the use of HEPAequipped dual cartridge respiratory and other persona! protection during maintenance activities. Prohibited Activities The training program for the maintenance engineering staff should describe methods of handling asbestos-containing materials as .veil as routine maintenance activities that are prohibited when asbestos-containing materials are involved. For example, maintenance staff employees should be instructed; :\'oi to drill holes in asbestos-containing materials; .\\>: to hang plants or pictures on structures covered with asbestos-containing materials Not to sand asbestos-containing floor tile; Not to damage asbestos-containing materials-while mo\. ing furniture or other objects: ' * Not to install curtains, drapes, or . dividers in such a way that they damage asbestos-containing materials: A'o/ to dust floors, ceilings, moldings or other surfaces in asbestos-contaminated environments with a dry brush or sweep with a dry broom; Not to use an ordinary vacuum to clean up asbestos-containing debris: Not '.o remove ceiling tries below asbestos-containing materials without wearing the proper respiratory protection, clearing the area of other people, and observing asbestos removal waste disposal procedures: Not to remove ventilation system filters dry: and Not io shake ventilation system filters. Appendix H to $ 2926.58--Substance Technical lafocmatioo for Asbestos, NonMandatory I. Substance Identification A. Substance: "Asbestos'* is the name of a class of magnesium-silicate minerals that occur in fibrous form. Minerals that are included in this group are chrysolite, crocidolite. amosite. anthophyllite asbestos, tremolite asbestos, and actinolite asbestos. B. Asbestos. tremolite. anthophyllite. and actinolite are used in the manufacture of heat-resistant clothing, automotive brake and clutch linings, and a variety of building materials including floor tiles, roofing felts, ceiling tiles, asbestos-cement pipe and sheet, and fire-resistant drywall. Asbestos, tremolite. anthophyllite and actinolite are also present in pipe and boiler insulation materials, and in sprayed-oa materials located on beams, in cruwlspaces, and between wails. C. The potential for an asbestos-containing product to release breathable fibers depends on its degree of friability. Friable means that the material can be crumbled with hand pressure and is therefore likely to emit fibers. The fibrous orQuay sprayed-on materials used for fireproofing, insulation, or sound proofing are considered to be friable, and they readily release airborne fibers if disturbed. Materials such as vinyl-asbestos Hour file or roofing felts are considered nonfnable and generally do not emit airborne fibers unless subjected to sanding or sawing operations. Asbestos-cement pipe or sheet can emit airborne fibers if the materials are cut or sawed, or Lf they are broken during demolition operations. D. P^-misstble exposure: Exposure to airborne asbestos, tremolitc. unihoph\Uite. and actinolite fibers may not exceed 0.2 fibers per cubic centimeter nf air (0.2 f.fcc) averaged over the 6-hourworkday. [1. Health Hazard Oata A. Asbestos. (reoiotite. entiwphyiliffi. and acbnoiite can cause disabling respiratory disease and various types of cancers if the fibers are inhaled. Inhaling or ingesting fibers, from contaminated clothing or skin can lso result in these diseases. The-symptoms of these diseases generally do not appear for 20 ^mply id ac:inolit or more years after initial exposure. - Process v B. Exposure to asbestos, tremolite.
