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. Asbestos has been widely used as insulation, structural wallboaxd, 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 asbestoscontaining insulation before the enactment of Federal regulations controlling the use and handling of asbestos. It is Dow's philosophy to eliminate the use of asbestos where feasible. The revised QSHA 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 removal, packaging, transport and disposed 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- SECTICN II HEALTH & ENVIRONMENTAL SCIENCES INFORMATION CENTER POTENTIAL HEALTH EFFECTS 01/07/87 ASBESTOS ER-0027-0713 REVISED: 12/11/86 SYNONYMS AMFfUBQLE PAGE 1 APPEARANCE: fibrous solid in various colors EXPOSURE GUIDELINES: OSHA PEL is 0.2 fibers (>5 um) per cc. 8 hr.

POTENTIAL HEALTH EFFECTS This section includes possible adverse effects which could occur if this material is not handled in the recommended manner. These effects apply to stated material and may not apply to dilutions or formulations of that material. ST0073 I 45 EYE - Mechanical injury only. SKIN - Mechanical injury only. - Skin absorption is unlikely due to physical properties. INGESTION - Single dose oral LD50 has not been determined. - Amounts ingested incidental to industrial handling are not likely to cause injury; however ingestion of larger amounts may cause injury. ACUTE INHALATION EFFECTS - Excessive exposure to dust causes chronic inflammations of lung tissue and pleural membranes, as well as cancers, in both man and animals. SUBCHRONIC EFFECTS - Prolonged exposure to asbestos dust has been found to cause pulmonary fibrosis (asbestosis), which may be disabling and even fatal. CHRONIC EFFECIS/CARCTNOGENICITY - Has been shewn to cause cancer in humans. - For hazard communication purposes under OSHA standard 29 CFR part 1910.1200, this chemical is listed as a carcinogen by NIP and IARC Group I.

DO 1. Get positive identification. Sample and have analysis performed at Analytical Services, phone 1075. 2. Take sufficient samples. Sane vessels, equipment, etc. may contain moire 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 them 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 asbestos 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 for matching replacement/repair of existing asbestos covered structures or equipment 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 hydrdblasting 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 rot 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- ST00731 52 SECTION V DO NOT'S 5. Eat, drink, smoke, chew gum/tobacco 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-operated 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. TYJA 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 dividers in such a way that they damage asbestos-containing materials 13. Dust floors, ceilings, moldings or other surfaces in asbestos-contaminated environments with a dry brush 14. Use an ordinary vacuum to clean up asbestos-containing debris 15. Remove ceiling tiles belcw asbestos-containing materials without wearing the proper respiratory protection, clearing the area of other people, and observing asbestos removal waste disposal procedures 16. Remove contaminated ventilation system filters without wetting. Do not shake. NOTE: Items 5 through 16 are directly from the OSHA Asbestos Regulations. -9- SECTION V SOME ASBESTOS-CONTAINING MATERIAIS IN BUILDINGS SUBDIVISION______________GENERIC NAME_________ASBESTOS (%) DATES OF USE BINDER/SIZING ST0073I 53 Surfacing material sprayed-or trcweled-on 1-95 1935-1970 sodium silicate, Portland cement, organic binders.

ST0073 I 66 REMOVAL If the gasket or packing to be removed is not adhered to the seating surfaces.and can be removed by hand without breaking apart, remove and package for disposed, according to Section IX of this manual. If the gasket or packing is adhered to the seating surfaces so that mechanical means are used and this operation creates particles in the air or surrounding area, then as a minimum, the asbestos abatement minimum requirements for glove bags or small-scale short-duration jobs shall be used. Spiral-wound gasket removal shall comply with the glove bag or small-scale short-duration minimum requirements if wet methods cannot be used. - CUTTING GENERAL: 1.

Two methods can be used to reduce exposure to asbestos fibers. The Enclosed Cylinder/HEPA Vacuum System Method and a wetting method. .. A. The Enclosed Cylinder/HEPA Filter Vacuum System Method consists of three components. * A wheel-shaped cylinder designed to cover and enclose the wheel assembly * A compressed-air hose and nozzle that fits into a port in the cylinder, and * A HEPA-filter vacuum used to evacuate airborne dust generated within the cylinder by the ccmpressed air. B. The wetting method consists of spraying water containing a surfactant to loosen the asbestos containing residue and to capture the resulting airborne particles in the water mist. * Begin spraying the asbestos-containing parts at a sufficient distance to ensure that the asbestos particles are not dislodged by the velocity of the water spray. * When the asbestos particles are thoroughly wetted, the spray will be brought closer to the parts and the parts will be sprayed as necessary to remove grease and other material. * The parts roust then be wiped with disposed, rags or towels which must be placed in a labelled plastic bag and sealed while they are still wet. -35- t ST0073 I 79 SECTION X ASBESTOS ABATEMENT MINIMUM REQUIREMENTS 2.
