THE DOW CHEMICAL COMPANY" TEXAS DIVISION FREEPORT, TEXAS 77SA1 September 6, 1972 MAINTKNANCK FOHEMKN ST05744I5 In order to obtain data on exposure levels during removal of asbestos-containing insulation, the Environmental Health Department must take several samples, during removal, of each type or class of asbestos insulation. This data must be obtained anu evaluated prior to December 1, 1972. Most high temperature insulations (above 800P) installed prior to August, 1970, should te suspected of containing asbestos. Before removing this type material, the appro priate Plant A or Plant B Insulation Foreman should be advised cf the .lob so that monitoring may be arranged as required. This information car. most readily be conveyed A complete revision of the ''Handbook for Handling Asbestos Materials" is attached; it defines the procedures and safe guards required for proper handling. It should be noted that, precautions for savsing of transite (cement-asbestos board) sre included. All waste asbestos-containing material must be properly bagged and labeled for disposal by the Yard Department. Labeling tags have been ordered (see attached sketch) but ar*o not yet available.

The intent- is to control the exposure of employees to asbestos dust through the proper use of safe work procedures and by the sub stitution of non-asbestos containing materials. Asbestos is widely used as structural wall board, insulation, and roofing material. Asbestos fibers are used as a mechanical reinforcing matrix in in sulation, roofing paper, certain piping systems, etc. However, Dow Ehgineering Specifications were revised to exclude asbestos-containing insulation prior to installation of Federal regulations controlling the use and handling of asbestos. Eventually, the use of asbestos will be eliminated as the ultimate solu tion to the problem. The OSHA standards -which became effective July 7, 1972 define the precautions required for asbestos handling and the allowable safe working limits. Should a hazard exist, and these procedures appear insufficient, contact the superintendent of the Plant A or B Functional groups for exceptions or variations. These procedures will be reissued prior to 7 December to incorporate revisions dictated by results obtained from the Division Monitoring P-ogram. SAFETY The health of -hose who breathe asucslos bust may bo 3srJ. o'..i3.1;/ affect.*d. .-{erul tr> can be similar but more serious than t'r.ooo caused the xore common ly !cncwn materials such us sills;:, and coal dust. This phenomena has been observed for many centuries. Current medical discoveries :;l:ow teat handling of asbestos by a confirmed clca-otte er.olcerr i s espec ially hazardous, in tec res of potentially serious lung disorders. J.t is recommended that those persons handling asbestos s:.v; smoko cl ga:,ottos in any quantity. When working with materials which contain asheston fiber, care must be taken to eliminate as much loose dust as possible. Wetting, Isolating the work area, or other suitable procedures tc eliminate the dust hazard are absolutely necessary. The main problem areas will be in removal of ole, deteriorated in sulation and the sawing of Transits. Respiratory protection, dust, collect ora, blowers, etc., will be mandatory where asbestos-containing material;-} must be handled. The two "nose and mouth" dust respirators vihlch have been approved by the Safety Copartment are; (l) MSA Dustfoe 77, Dow Stock No. 15-2?C'J5, Cartridge No. i-5-2377t> and (2) Wilson Dust Respirator, Dow Stock No. 15-2.5460, Cartridge Xo. 15-23790. Disposal of asbestos will he In polyethylene bags. Dew Stock No. 15-05030 for largo bag arid 15-04170 through 15-04l85 for small bags. Ac required, special protective clothing such as cover alls, head covering and gloves will be provided. Such requirements will be determines by the Division Moni toring Program.

In some cases, job conditions may dtebnbe none stringent, requirements. Those could include com pletely wetting down the a .'a w;l in viator when re moving old insulation, or completely isolating the work area with tarpaulins, etc. Specific require ments for each Job will be detailed on the"Insulators Safety Check List." Because Dow's Engineering Specifications have been re vised to exclude use of asbestos-containing insulation, most of the Safe V,rcrk Procedures in this section of the Manual will seldom be referred to t'or new installations. These procedures are to be used in conjunction with Plant Safety liu.les, Maintenance Standard Safe fork Procedures for the Area, and Safety Standards. c/> --i :.Z> ai --1 ro o SAPP.

The eight hour time-weighted average shall not exceed five (b) fibers per cubic centimeter.* In order to assure corapliar.co with these limits., the Environmental Health Group will make random samples. When special field testing is desired, call Environmental Health at ?-3ft-2L21. In order to keep asbestos dust concentration within the proper limits, any dusty conditions connected with the handling of asbestos materials must be kept to an absolute minimum. This must be done as out lined in the previous Safe Work Procedures by wetting down the area, pre-soaking the material, or vacuuming the material as it is cut. Each individual job should be planned with this uppermost in mind. co --i :~) CA ---j ("O * Effective I July 1976, ibis limited Is reduced from five (p) to i/Wo (?) fibers per cubic centimeter. 11 'a^> ' 'OaLsds ^UI&H. i.O %f't ^iU^JSuJ}, ^ sxS&U-i'Uj-. `^h'$jCpL,<D t ST0574428
