  1. Asbestos Awareness Developed by: State Safety and Industrial Hygiene Unit Department of Employee Relations September 2000

  2. Asbestos Awareness Purpose of training: • Provide all employees with basic information about asbestos and its hazards, • Identify typical asbestos-containing materials within employee work areas, • This training does not qualify employees to work with asbestos-containing materials

  3. Asbestos Awareness What is Asbestos???? • Naturally occurring fibrous mineral • Six different forms of asbestos Chrysotile - most common type in US (95%) Amosite - 2nd most common (2-3%) Crocidolite - 3rd most common (1-2%) Actinolite Anthophyllite Tremolite

  4. Asbestos Awareness Where does asbestos come from??? • Mined from the ground • Contaminant with other minerals (vermiculite) • physical properties ideal for building • materials Why do we use asbestos???

  5. Asbestos Awareness • What makes asbestos unique? • Abundant • Cheap • Fibers cleave into smaller fibers • What makes asbestos dangerous? • Extremely small fibers are very aerodynamic • (Fibers can remain airborne for extended periods of time and inhaled into the deep lung)

  6. Asbestos Awareness • Friable vs. Nonfriable - what’s more hazardous? • Friable - easily crumbled to dust using hand pressure • Spray fireproofing • Pipe insulation • Nonfriable - not easily crumbled by hand but can be crumbled by mechanical means • Floor tile • Roofing products

  7. Asbestos Awareness • Physical properties • Thermal resistance • Forms fibers with high tensile strength • Chemically inert • Absorbs sound • Electrical insulator

  8. Asbestos Awareness • History of uses: • Used in classical times by greeks and romans • Modern use began in 1880’s • Extensively used by US during WWII • Used in buildings extensively 1940’s-1970’s • Limited asbestos products still available today • asbestos use extensive in developing • countries

  9. Asbestos Awareness • How do we know if something is asbestos-containing? • Requires laboratory analysis with microscope • Certain products routinely contain asbestos

  10. Asbestos Awareness • Common asbestos-containing materials Pipe, boiler and duct insulation Sprayed or troweled plaster Spray fire proofing Cement pipes and panels Mechanical gaskets and packing Ceiling tiles Floor tile and adhesive Linoleum backing

  11. Asbestos Awareness Health hazards of asbestos exposure • Asbestosis - fribrotic scaring of the lungs • 10-20 year latency period • Associated with high dose exposure • Smoking creates synergistic effect • Increased chance of other asbestos diseases

  12. Asbestosis fatalities Spray-on use ends

  13. Asbestos Awareness Health hazards of asbestos exposure • Mesothelioma - cancer of the chest cavity • 20-40 year latency period • Not necessarily associated with high dose exposure • Rare • Almost always fatal

  14. Asbestos Awareness Health hazards of asbestos exposure • Lung cancer • 20-30 year latency period • Many other causes of lung cancer • Most frequent form of asbestos disease today • Smoking synergistic effect (50-90 times) • Associated with high doses

  15. Asbestos Awareness Asbestos is extensively regulated! • Regulated by: • State and federal OSHA • Environmental Protection Agency (EPA) • Minnesota Pollution Control Agency (MPCA) • Minnesota Department of Health (MDH)

  16. Asbestos Awareness OSHA Regulations • Requires employee training (i.E. This training) • Exposure monitoring when working with asbestos • Establishes “permissible exposure level” for employees = 0.01 fibers per cubic centimeter (cc) of air (1 cc is approximately a sugar cube) • Identifies work practices • Identifies personal protection requirements • Identifies work practice prohibitions

  17. Asbestos Awareness EPA and MPCA regulations • Requires building survey prior to construction work • Removal of asbestos containing materials before renovation or demolition • Establishes notification requirements • Defines proper transport and disposal requirements • EPA regulates asbestos in schools

  18. Asbestos Awareness MDH regulations • Requires building survey prior to construction work • Requires building owners to maintain asbestos- containing materials in good condition • Requires certification of people working with asbestos • Identifies notification requirements • Establishes specific removal procedures • Establishes clearance criteria for removal projects

  19. Asbestos Awareness Your responsibilities: • Do not damage or disturb any asbestos-containing materials • Immediately report the presence of damaged asbestos-containing or suspect asbestos-containing material to your supervisor or asbestos coordinator • Verify that building materials you will be working with are not asbestos-containing

  20. Asbestos Awareness Asbestos-containing materials in our facility:
