10 BACKGROUND INFORMATION n FRIABLE VS. NON-FRIABLE –FRIABLE CRUMBLED BY HAND PRESSURE SANDED,GROUND ABILITY TO BE AIRBORNE –NON-FRIABLE HARD/ROCK LIKE

11 Non-Friable Friable

12 BACKGROUND INFORMATION n CATEGORIES OF ACBM/PACM –SURFACING SPRAY/TROWLED –THERMAL SYSTEM INHIBIT HEAT TRANSFER –MISCELLANEOUS ANY OTHER MATERIAL

13 BACKGROUND INFORMATION n PROPERTIES OF ASBESTOS –FIRE RESISTANT –THERMAL QUALITIES –ACOUSTICAL PROPERTIES –ELECTRICAL INSULATOR –TENSILE STRENGTH –CHEMICALLY REST

14 BACKGROUND INFORMATION n COMMON USES OF ASBESTOS –PIPE INSULATION –BOILER BREECH/LAGGING –BOILER DOOR –FIRE PROOFING –DEC/ACOUSTICAL –CEILING TILE –ROOFING –ELECTRICAL INSULATION

15 HEALTH EFFECTS n HARMFUL PROPERTIES –SIZE OF FIBER –DURABILITY FIBERGLASS 2-3 YEARS ASBESTOS >100 YEARS –SHAPE OF FIBER –BODIES ABILITY TO BREAK DOWN –NO PROOF ON DIFFERENT TOXICITY

16 HEALTH EFFECTS n MAN-MADE MATERIALS –FIBERGLASS n ROUTES OF ENTRY –INHALATION –INGESTION

17 HEALTH EFFECTS n RESPIRATORY SYSTEM –NATURAL DEFENSE NASAL HAIRS MUCUS SILIVA CILIA TRACHEA PRIMARY BRONCHI –DEEP LUNG ALVEOLI EXCHANGE OF GASES

18 ASBESTOS RELATED DISEASES n ASBESTOSIS –LUNG DISEASE CALLED ASBESTOSIS DIAGNOSED IN 1900 –SCARING OR FIBROSIS OF THE LUNG TISSUE IMPAIRS ELASTICITY RESTRICTS O2 INTAKE –LATENCY PERIOD:15-30 YEARS –IRREVERSIBLE WITH NO CURE

19 ASBESTOS RELATED DISEASES n LUNG CANCER –MALIGNANT TUMOR OF THE BRONCHI COVERING –LATENCY PERIOD: 20-30 YEARS

20 ASBESTOS RELATED DISEASES n MESOTHELIOMA –CANCER OF THE MESOTHELIUM LINING OF CHEST/ABDOMEN –AT TIME OF DIAGNOSES USUALLY FATAL –NO DOSE RESPONSE EFFECT –LANTENCY PERIOD: 30-40 YEARS n OTHER DISEASES

21 HEALTH EFFECTS –SYNERGISTIC RELATIONSHIP BETWEEN ASBESTOS AND SMOKING –20 CIGARETTES/DAY –10X FOR LUNG CANCER ASBESTOS ONLY –5X FOR LUNG CANCER CIGARETTES + ASBESTOS 90X GREATER
