Although tremendously valuable to industry, these minerals have bees closely listed to astostosis, a degenerative lung-aearring disease, aad to lung cancer, The Oeoupatleaal Safety and Health Administration (OSHA), therefore, baa regulated employea exposure to asbestos since shortly after the agency1 s inception. OSSA h&B defined asbestos, established standards for its use, end set permissible expo sure limits. The initial airborne asbestos fiber limits have bees revised downward. Regulations under the OSHA asbestos standard are covered in 29 CER 1910.1001. Asbestos exposure in Ontario is regulated under the Occupational Health and Safety let (Revised Statutes of Ontario, 1980, Chapter 321, August 1982). Exposure limits presently differ under the two regulations; however, industrial hygisne work practices to control dust and fiber in air are the same. Six fibrous minerals, mentors of a family called silicates, are recognised as astostosi chrysotile (white asbestos), actinolite, aaosite (brown asbestos), aathoptayllite, orocidolite (blua asbestos) and tremolite. Counneretally, chrysotile is the most impor tant form of asbestos, accounting for approximately 95? of the asbestos used in North America. Some talc contains.various amounts of asbestos. Asbestos has about 3000 different uses, with approximately two-thirds being used in the construction industry in building products, inaulatim, friction natarials, and textiles. Manufactured products have inoludsd reinforced asbestos cement sheets and pipes, patching and taping compounds, floor and ceiling tiles as well as paints, costings and sealants containing asbestos as reinforcing fillers, pipe linings and fillers for various liquids, friction products include dutch facings end brake linings for automobiles and trucks, railroad care, airplane6, and industrial machinery. A variety of other uses ore known including theater curtains, fire blankets and other thermal protection, filtration materials aad, until roosatly, dry wall patch compounds and imitation fireplace ashes. Once incorporated into manufactured items, hazards resulting frcm asbestos aro less probable, as long ae the substance is not disrupted. However, the fibers are nearly indestructible, end a potential health risk arises whenever asbestos fibers are set free, re suiting is airborne asbestos dust. Health Hatarde Asbestos exposure can causa astostosis, cancer of the lungs and digestive tract, and mesothelioma. Astostosis ie a diffuse fibrotio lung disease caused by exposure to high concentrations of asbestos dust and fiber, usually after several years of exposure. Tbs onset cf astostosis appears to depend os dust and fiber concentration, fiber shapes, type of asbestos, and length of exposure, Usually, the disease toeoaes evident 20 or more years after the first exposure to asbestos. Once established, however, a highly disabling pneumoconiosis can progress even after exposure has ceased. Bronchogenic carcinoma (lung canear) and mesothelioma of the pleura and peritoneum (cancer of membranous lining of the chest end abdominal cavities) are also associated with asbestos exposure. Excesses of canoer of the larynx, stomach, colon, and rectum h&VB also been observed. Some forms of asbestos appear for more hazardous than others. Aa with astostosis, there eon to a long latest period, generally more than 25 years for mesothelioma. The mechanism of action is not currently known. Asbestos is different from most chemical carcinogens beoause it ie not metabolised. Thus even limited expo sures to high levels leads to continuing presence of inhaled astoetoe particles or - over - PRObUCro vBiy FORD IN PRODUCED BY FORD SBBttMBCMif1^TWWT'BinH.niriTMn - 105584 SCF-ALLF-08980 Bulletin Bo. k -2- &/22/B3 I fibers witbin the lung. These can translocate to the abdominal cavity and to other tissues. The prognosis for asbestosis and asbestos-induoed cancer is generally poor. Risks of disease due to asbestos exposure hare not been defined clearly for all oeeupational groups known to have significant closure, firs epidemiological data ars available only for heavily exposed workers employed in asbestos mining, nanufaeturing and insulation handling. Howaver, there is evidenos that the problem is more widespread than previously believed and that workers from a variety of trades and occupations, including painters, electricians, carpenters, machinists, boiler maker*, pipefitters, mechanics, welders, and ethers, may be at increased risk. The issue of risk of disease from asbestos exposure is further complicated in that smokers who have had asbestos exposure clearly have markedly increased risk of developing lung disease related to aabeetoa. Asbestos exposure** vithin Vard Hotor Company may occur from . Insulated pipe covering for parts washers sad olaanars, steam and hot water lines. , Insulated coverings for boilers and associated parts in powerhouses. Drying oven and furnace insulation. Asbestos blocks, bricks, sheets, and sleeves. . Clutch and brake linings for various maohlnery and transportation equipment (power presses, conveyor beltB, hi-loe, locomotives, tow tractors, trucks, automobiles). . High temperature gasket materials for manifolds, pipes. . High temperature blankets, gloves. 011576 . Asbestos-containing parting compounds, certain talcs. Filtration media. Employee Exposure # Sines we do not manufacture asbestos materials, exposures are primarily limited to those who work with asbestos-containing products. However, these exposures ere no less significant. Employee exposure can generally occur during material handling and maintenance of asbestos-containing friction materials. Exposure can occur during grinding, saving, sanding, drilling, or otherwise disturbing or finishing asbestos-- containing products. Demolition, removal, and repair of asbestos coverings and coatings offer other eouroes of worker exposure. Insulation removal or repair and brake and clutch servicing can be especially bscardoua. Permissible Occupational Exposure Limits (PEL) -- Breathing Zone Concentrations Eight-hour tiae-weighted average expoiuret 2 fibers longer than 5 micrometers per cubio centimeter of six (2 f/ec >5 pm). Ceiling concentration: 10 f/eo >5 pa. Ontario TVAE PEL for smosite, crocidolite, and other forma of asbestos are 0.5, 0.2, and 1.0 f/ce >5;um, respectively. The Ontario ceiling PEL for amosite, crocidolite, and other forms are 2.5, 1.0, end 5*0 f/cc >5 pa, respectively. Methods of Compliance . . Engineering controls, such es isolation, enclosure, local exhaust ventilation, and dust collection are required and should be used to meet the PEL. . Compliance with the PEL may not be achieved by sole use of respirators or shift rotation except under special conditions approved by Industrial Hygiene. . AH bend and power operated tools, which may produce or release asbestos fibers in excess of the PEL, must be provided With local exhaust ventilation. . Insofar ae practicable or unless the usefulness of the product would be diminished, asbestos must be handled, mixed, applied, removed, out, scored, or otherwise - worked in a wet state. Vet methods of control are very effective in suppressing airborne asoestoB fiber and dust in pipe and furnace insulation repair and demolition. , PROPERTY OF ' FORD MOTOR COMPANY PRODUCED BY FORD Bullatin Ho. 4 -3 8/22/63 .

Employes Health Servioea Asbestos Insulation Removal and. Repair (Supplement to Bulletin No. 4} MOKMI ......... ......... MTCb------------------New 1 ------------_- ------ -....---- 1--- Most boiler, furnaoe, steam, and oondensate piping insulation installed prior to 1975 oontains asbestos, the removal or maintenance of dry asbestos insulation oan be very hazardous to health. Old asbestos-containing insulation tends to be dry, very friable, and oan easily generate high concentrations of airborne fibers and dust if oarelessly handled.. Stringent industrial hygiene precautions mist, therefore, be taken to protect employee health by preventing inhalation of asbestos duet and fibera. The following procedures and steps are recommended to minimise dust exposures during asbestos-containing insulation demolition, removal, and repair. They supplement work practioea, engineering controls, and personal protective equipment usage specified in Industrial Hygiene Bulletin No. 4 and in OSBA and Ontario OHSA asbestos standards and regulations. These procedures apply primarily to protection of pipe ooverers and insulation maintenance and installation employees. Compliance with these procedures should assure that others in vicinity of insulation maintenance activities are not exoessively exposed to airborne asbestos fibers. These industrial hygiene work practices focus on safe techniques for removing asbestos insulation from older equipment and build ings. They do not address asbestos encapsulation, top-coating, or enclosure methods. 1* Steam and hot water pipes, fumaoes, boilers, ovens, and other equipment must not be reinsulated with asbestos-oontaining products including insulation oemonte, tape, and grout. Suppliers of acceptable substitute insulation for asbestos oan be provided by Plant Engineering Offioe, Manufacturing Staff (Meohanioal Design and Equipment Standards, page M4-1, January 1976). > 2. Unless there is specific evidenoe to the eontrary, all insulation should be treated and bandied aa if it ia aabestos-oontaining until proven otherwise. Samples of insulation materials suspected of containing asbestos may be submitted to the Indus trial Hygiene Laboratory who will return an analytical report of amounts and types of asbestos in the samples. Contact Industrial Hygiene at 33-78955 for sampling procedure end shipment method. A profile and map of asbestos-containing insulation in the plant can be established by a judicious sampling and boiler and steam pipe tagging procedure. 3. Removal of aabestos-oontaining insulation associated with renovation or demolition should be done by an outside contractor with proven experience in successfully--^ handling this hazardous work in compliance with OSHA standards. The cost and/or inconvenience associated with utilization of a specialized contractor is justified by elimination of potential inhalation health risks. Any outside contracting should be oonsistent with the outside oontraeting clearance procedure provided for in the 'current Company-UAH agreement. 4. InsUlation-hendling areas must be posted and restricted to prevent unauthorized entry ae specified in OSHA regulations. ' 5. The number of employees authorized to handle`asbestos-oontaining insulation should be kept to a minimum. A designated crew, educated and trained in proper insulation handling, work practioea, who understands OSHA asbestos regulations, and baa reviewed this bulletin, is reconmended. As far as feasible, work should be performed at a time when any inadvertent fugitive asbestos fiber emissions would expose fewest-. ' people in adjaoent areas. " " 6. Insulation should not''be removed, handled, or scored, sawed, or drilled until it has been thoroughly soaked with water. Wherever possible, steam flow should be inter rupted to prevent wet insulation next to pipe from drying out during insulation - over - . 2**0 9008 PRODUCED BY FORD Bulletin No. 4b -2- o/aa/oi removal. A vetting agent such ae a dishvasher rineing aid can be added to the water to promote rapid, complete vetting of the insulation. During handling and saving, x small atomizer bottle (e.g. "Winder") can be used to spray insulation to keep it ' vet until sealed in labeled, plastic trash bags. .* 7. Employees handling vet insulation must wear respiratory protection equivalent to that provided by a 3M 9920 air-purifying respirator. All employees must be included in a. respiratory protection control program in compliance vith OSHA standards. 6. Disposable polyethylene Bheeting should be placed on floor belov removal site to catch insulation debris provided the drop is not too far (e.g. greater than 10 feet). Othervise,'polyethylene sheeting hammocks should be suspended belov steam pipe lines to catch vet insulation as it falls. Vet residue should not be allowed to dry before it is placed in trash bags. Vehicle and pedestrian traffic should not be allowed to disturb unbagged insulation debris. 9* An alternate dust containment procedure is available for situations where vet methods of dust suppression cannot be used during removal of asbestos pipe covering. A poly ethylene bag attaches to a pipe and seals the insulation for isolated removal by the attached "Tyvek" and latex gloves. The bag is moved along the pipe in sections until the insulation is removed. About 50 feet of pipe insulation can be handled vith one bag. The bag and attached remote-handling gloves containing the asbestos insulation debris may be disposed after precautionary labeling. Bags are available from: Asbestos Control Technology, Inc. 38 North Pine Street Maple Shade, Nev Jersey 08052 Employees removing insulation by this method must wear respiratory protection bb .^ specified in Item 7* l-J) > 10. Employees must wear disposable protective clothing if, during insulation removal and maintenance, regular work clothing could be contaminated vith asbestos dust and fibers. duPont "Tyvek" coveralls, jackets, and hoods are recommended. Gloves and disposable overshoes are required. 11. Vhen insulation cannot be worked thoroughly vetted vith vater or within enclosed containment bags (as specified in Item 9) ore rigorous respiratory protection is required. Depending on respiratory protection factor required, either full-facepiece powered air purifying respirators or Type C full-facepiece supplied-air respirators, continuous flow or pressure demand class, must be used. Such situations would be rare and should normally be bandied by approved outside contractor. Industrial Hygiene should be consulted vhen wet methods, containment bags, or outside contractors cannot be used. 12. The use of power-operated tools on asbestos-containing insulation iB discouraged unless the asbestos is thoroughly vetted or ms chemical local exhaust ventilation captures all airborne dust and discharges outside the plant vith no possibility of reentry. 13* The use of compressed air to remove asbestos insulation from pipes is prohibited. Dry wire brushing of asbestos-contaminated pipeB is not permitted unless local exhaust ventilation is used. 14. Tvo training aids are available: - Employee Health Servioes slide-tape cassette mentioned in Industrial Hygiene Bulletin No. 4. - An OSHA film: "Asbestos Control: Encapsulation, Enclosure, and Removal", a nine-minute presentation using on-site soenes to stress good vork practices for the control and removal of asbestos ($28). mMwm 8006 0441 ) PRODUCED BY FORD
