U/l/ ISX - ! UNION CARBIDE CORPORATION o TECHNICAL CENTER f SOUTH CHARLESTON, WEST VIRGINIA RECEIVED MEMORANDUM SEPTEMBER 30, 1983 OCT 4 ist>3 R C. ELLIS TO: COPY: FROM: SUBJECT: Mr. C. D. Twait Mr. P. D. Black* Mr. R. C. Ellis* Mr. J. E. Liana* Mr. E. C. Powell, Jr. Mr. J. L. Riffle* Mr. D. T. Watters D. W. Moody, Jr. ASBESTOS FIBERS HEALTH CRITERIA/SAFETY-HEALTH TECHNOLOGY MANAUL This is in response to your memo of September 23, 1983 requesting information on current sources of asbestos in Carbide plants. Our above grade valve and piping specifications specify asbestos for the following: 1) Valve packing 2) Gaskets (Both compressed asbestos and spiralwound with asbestos filter.) We do not.plan to expand the use of asbestos to other items. Our specifications for potable water above grade specify asbestos for both valve packing and gaskets. We do not have specifications for breathing air in the PIPING TECHNOLOGY-VALVE AND PIPING SPECIFICATIONS Manual. However, since our plants have breathing air lines, you may wish to check with them to determine if they use asbestos in this service. P. D. Black is responsible for our underground piping specifications. You should check with him regarding the specification of asbestos in under group lines. Let me know if you need additional information.

All Insulation materials approved through the use of UCC Insulation Standards have been specified asbestos-free since 1976; however, insulation installed before that contained asbestos fibers. Special precautions should be taken to assure that an/ new construction installed as nodules is not supplied to UCC with asbestos-containing insulation. 17.1 GEHERAL Asbestos refers to a number of naturally occurring fibrous ninerals of which there are six major Types: CD Actinollte - ZCaO-AHgO-FeO-aSiOg-H^ (2) Anoslte - 5.5FeO-!.9lgO-8Si02-HzO (3) Anthophyllite - TNgO-flSfO^-H^ (A) Chrysotile - 3Mg0-2Sf0z-2H20 (5) Crocidoltte - ^O-Fe^-SfeO-BSIOj-H^ (6) Tremollte - ZCaO-WgO-aSIOj-H^ The principal type is chrysotile. 11.2 HEALTH EFFECTS Inhalation of all types of asbestos fibers has been associated with these diseases: (7) Asbestos!i, (21 Bronchial carcinoma, (3) Cancer of the gastro-intestinel tract, (4) Mesothelioma 11.2.1 Asbestosis. Asbestos)s Is non-mallgrant scarring of the lung tissues that Is caused by the formation of abnormal fibrous tissues connecting the lungs and pleura (the delicate membrane encasing the lungs). This tissue formation Induced by asbestos continual even after exposure to asbestos fibers has ceased. The average onset time for asbestosis is 20 to 40 years. The symptoms of this fatal disease is shortness of breath. 11-2.2 Bronchial Carcinoma. Bronchial carcinoaa Is a form of lung cancer which may develop from asbestosis. It has an average onset time of 40 years. It fs suspected that many of the people who had been occupationally exposed to asbestos fibers die from asbestosis before contracting bronchial carcinoma. 11.2.3 Sastro-intestlnal cancer. Cancer of the gastro-intestfnal tract has been linked to inhalation of asbestos fibers. Because adverse health effects from Ingestion of asbestos fibers have not been determined, asbestos-cement pipe, asbestos gaskets, and occasionally even asbestos filters are still used 1h potable water end food-processing systems. However, this link between gastro-intestlnal cancer and asbestos Inhalation has increased the concern about the harmful effects from swallowing asbestos fibers. 11.2.4 Mesothelioma. Mesothelioma Is a fatal tunor of either the pleura or of the peritoneum (the pleura-like membrane that lines the abdominal cavity) and also has a long latency period. 11.3 UCC Exposure Limits The Internal Exposure Standards list, which Is compiled by the UCC Health Effects Review Board and Included In the UCC Occupational Health Manual, specifies the exposure limits for asbestos to be followed for UCC employees In the U.S. and Puerto Rico. It also lists asbestos ax a known carcinogen. UCC 022310 PAGE 2 OF 2 SEPTEMBER 1963 O., i CENTRAL ENGINEERING 11.4 Handling and Removal of Asbestos-Containing Insulation Material Federal OSHA regulation 29 CFR 1910.1001 specifies exposure limits, work practices, personal protective equipment, personnel monitoring, sign-posting, and record-keeping requirements regarding asbestos fibers- UCC fteconmended Practice SH-255, Removal and Handling Asbestos-Containing Insolation Material, describes procedures to comply with OSHA and EPA regulations and to ensure the safety and health of UCC employees. EPA regulation 40 CFR 61 requires specific removal and disposal practices and also require notification of demolition or renovation activities that Involve the removal and disposal of asbestos-containing insulation material. ) i i UCC 022311
