The intent is to control personnel exposure to asbestos dust through training, asbestos maintenance programs, safe work procedures, proper use of protective equipment, and by the substitution of non-asbestos containing materials. It is Dow's philosophy to eliminate the use of asbestos where feasible. MAJOR MANAGER APPROVAL IS REQUIRED WHEN USING ASBESTOS MATERIALS IF A SUITABLE ALTERNATE IS KNOWN. Asbestos has been widely used as insulation, structural wallboard, roofing material, etc. Asbestos fibers are currently in use as a mechanical reinforcing matrix in insulation, roofing paper, certain piping systems, gaskets, brake linings, clutch plates, etc. Dow Engineering Specifications were revised in 1970 to exclude asbestos-containing insulation before the enactment of Federal regulations controlling the use and handling of asbestos. The revised OSHA standards (1910.1001 and 1926.58) which became effective July 21, 1986 define the precautions, procedures and controls required for asbestos handling. These standards also define the allowable exposure levels and the manner of determining exposure levels. The National Emission Standard for Hazardous Air Pollutants (NESHAP) also established specific requirements for notification, removal, packaging, transport and disposal of asbestos-containing materials. Violations of these regulations may result in a citation or fine or both. Dow is committed to meeting or exceeding government regulations, to protect the health of personnel. -1- ST0224845 SECTION II HEALTH & ENVIRONMENTAL SCIENCES INFORMATION CENTER POTENTIAL HEALTH EFFECTS ASBESTOS DR-0027-0713 REVISED: 10/14/88 SYNONYMS AMPHIBOLE APPEARANCE: fibrous solid in various colors EXPOSURE GUIDELINES: OSHA PEL is 0.2 fibers (>5 urn) per cc. 8 hr. TWA OSHA General Industry Standard 29CFRI910.1001. OSHA Construction Standard 29CFR1926.58. OSHA Excursion Limit is 1 fiber/cc averaged over a sampling period of 30 minutes. ACGIH TLV is 0.5 fibers (>5 urn) per cc for amosite, Ala; 0.2 fibers (>5 urn) per cc for crocidolite; 2 fibers (>5 urn) per cc for chrysotile and other forms of asbestos, Ala. POTENTIAL HEALTH EFFECTS This section includes possible adverse effects which could occur if this material is not handled in the recommended manner. EYE - Mechanical injury only.

Get positive identification. Sample and have analysis performed at Analytical Services, phone 409-226-1199. 2. Take sufficient samples. Some vessels, equipment, etc. may contain more than one type of insulation. Asbestos materials may be covered by refractory, siding, or insulation. 3. Consult the appropriate section of this handbook if asbestos is present. Materials containing more than 0.1% by weight must be handled as asbestos. 4. Put all asbestos waste (old insulation, transite, mastic, dust collector solids, disposable clothing, gaskets, packing, shingles, Haveg piping, furnace refractories, pump packing, pipe gaskets, brake shoes, etc.) in approved containers for disposal. The containers must be properly labeled to warn of the asbestos hazard and sent to the designated asbestas landfill. 5. Inform all personnel in the general area that asbestos work is in progress. DO NOT 1. Use materials containing asbestos (i.e. insulation, fireproofing, transite siding, Haveg piping, weatherproofing, and cooling tower materials) where an adequate alternate exists. MAJOR MANAGER APPROVAL IS REQUIRED WHEN USING ASBESTOS MATERIALS IF A SUITABLE ALTERNATE IS KNOWN. 2. Use asbestos labeled bags for disposal of general trash because of landfill permit requirements. 3. Sandblast or hydroblast materials containing asbestos. When sandblasting or hydroblasting adjacent areas, protect the asbestos materials from overblast. Examples of items to be protected are transite walls, pipe insulation, fireproofing, etc. 4. Use compressed air to remove asbestos materials. For example, do not clean brake drums and clutch housings with compressed air. This procedure may fill the surrounding atmosphere with asbestos fibers. An acceptable method is to use an approved vacuum. Dispose of the debris in approved containers and send to the designated asbestos landfill. -8- SECTION V ASBESTOS DO'S AND DON'TS (Cont'd) 5. Eat, drink, smoke, chew gum/tobac.co products, or apply cosmetics in a regulated area or a decontamination area. 6. Dry sweep asbestos materials. 7. Spray asbestos-containing materials. 8. Use hand-operated or power-operited tools (such as but not limited to saws, scorers, abrasive wheels and drills) without local exhaust ventilation if the use of these tools would cause asbestos exposures to personnel in excess of 0.2 fiber cc. 8 hr. TWA. 9. Hang plants or pictures on structures covered with asbestos-containing materials. 10. Sand asbestos-containing floor- tiles. 11. Damage asbestos-containing materials while moving furniture or other objects. 12. Install curtains, drapes, or d'viders in such a way that they damage asbestos-containing materials. 13.

Special purpose, 6 mil, polyethylene bags with the appropriate label are available through Dow Stock #17-30522. -22- SECTION X PACKAGING OF ASBESTOS WASTE FOR DISPOSAL 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. The recommended container is a 6-mil thick polyethylene bag. These bags are available through Dow Stock #17-30522. Other acceptable containers are polyethylene lined cardboard containers or polyethylene lined metal containers (drums, dempster boxes, or dino boxes). Polyethylene bags labeled with an approved asbestos label must be used only for bagging asbestos waste. When using bags, minimize the amount of void space or air in the bags to minimize their bursting during stacking and disposal. All containers used for asbestos waste must be sealed to make them leak-tight. Torn bags must be rebagged (double bagged) rather than repaired by taping. Disposable clothing worn during asbestos removal, packaging, and disposal must be placed into properly labeled polyethylene bags and disposed of as asbestos waste. An open-top fiber or steel drum containing a polyethylene liner may be used to accumulate small quantities of bagged and sealed asbestos waste (brake shoes, b'-ake dust, garlock gaskets, etc.). The drum must have an approved warning label, be labeled for asbestos waste use only, and the top must be kept on except during deposit of waste. All dempsters used for unbagged asbestos waste must contain a disposable polyethylene liner obtained from, or approved by, Environmental Operations. Dempster boxes must not be fil;ed higher than the top of the walls. Dempster liners must be lapped over and secured for temporary closure whenever the job is discontinued for a prolonged period (overnight, holiday, weekend). Dempster liners must be securely closed before transport of the dempsters; the sides and ends are to be lapped over and then secured. Proper lapping and sealing procedures are provided in instructions by Environmental Operations. Tie-downs for dempster liners must not be attached to the dempster boxes. All dempster boxes used for asbestos waste packaging and transport, and all packages of asbestos waste (including dempster liners) must be labeled with an OSHA-approved label. Note: Call 409-238-1176 for information.
