what is asbestos
What is Asbestos?
  • Friable
  • Detectable only with a microscope
  • Mineral Fibers
    • Long & Thin
    • Strong
    • Flame/Heat resistant
    • Durable

is asbestos still around
Is Asbestos Still Around?
  • New uses banned in 1989
  • Damage to structures
    • Fibers become airborne
  • Siding and Roofing
  • Cement
  • Insulation
  • Gaskets
  • Friction products – brake pads

asbestos is inhaled how do fibers get into the air
Asbestos is inhaled, how do fibers get into the air?
  • When asbestos is disturbed particles can become airborne
  • Asbestos is most dangerous when friable
  • Friable means it can be easily crushed or crumbled

health hazards of exposure
Health Hazards of Exposure
  • High blood pressure in your lungs
  • Heart problems
  • Asbestosis
  • Lung Cancer
  • Malignant Mesothelioma
  • Progressive Respiratory Insufficiency
  • Other cancers
health hazards of exposure pulmonary hypertension
Health Hazards of Exposure - Pulmonary Hypertension
  • Arteries of the lung become blocked or narrow due to asbestosis-related scar tissue.

http:www.nlm.nih.gov/medplus/ency/imagepages/9596.htm

health hazards of exposure heart problems cor pulmonale
Health Hazards of Exposure -Heart Problems – Cor Pulmonale
  • Excess pressure in the lungs causes the right ventricle, which is responsible for bringing the oxygen poor blood into the lungs, to work harder to pump the blood.
  • Causing the right ventricle to weaken and possibly fail.

health hazards of exposure13
Health Hazards of Exposure
  • High blood pressure in your lungs
  • Heart problems
  • Asbestosis
  • Lung Cancer
  • Malignant Mesothelioma
  • Progressive Respiratory Insufficiency
  • Other cancers
health hazards of exposure asbestosis
Health Hazards of Exposure -Asbestosis
  • Chronic, non-cancerous
  • Progressive
  • Leads to disability or death
  • Asbestos fibers cause the lung tissues to scar, scarring spreads making it harder to breathe
  • Symptoms – shortness of breath, a cough, blood in fluid coughed up from lungs, pain in chest or abdomen, significant weight loss, difficulty swallowing

Health Hazards of Exposure
  • High blood pressure in your lungs

  • Asbestosis
  • Lung Cancer
  • Malignant Mesothelioma
  • Progressive Respiratory Insufficiency
  • Other cancers
health hazards of exposure lung cancer
Health Hazards of Exposure -Lung Cancer
  • Lung cancer causes the largest number of deaths related to asbestos exposure
  • The risk can be 90 times higher if you smoke and have asbestos exposure.

health hazards of exposure17
Health Hazards of Exposure
  • High blood pressure in your lungs
  • Heart problems
  • Asbestosis
  • Lung Cancer
  • Malignant Mesothelioma
  • Progressive Respiratory Insufficiency
  • Other cancers
health hazards of exposure mesothelioma
Health Hazards of Exposure - Mesothelioma

Mesothelioma

  • a rare form of cancer of the lining of the lungs, chest and abdomen.
  • it spreads very quickly and eventually the patient cannot breathe.
  • it is painful and always fatal.

  • High blood pressure in your lungs
  • Heart problems
  • Asbestosis
  • Lung Cancer
  • Malignant Mesothelioma
  • Progressive Respiratory Insufficiency
  • Other cancers
health hazards of exposure other cancers
Health Hazards of Exposure - Other Cancers

Fibers can enter the mouth and be swallowed causing cancers in the:

  • Esophagus
  • Larynx
  • Oral cavity
  • Stomach
  • Colon
  • Kidney
  • This can happen if you are careless with food and drinks in contaminated areas.

who is at risk
Who is at Risk?
  • Nearly everyone is exposed to asbestos
  • Brief exposure probably won’t cause harm
  • Most illness caused by regular exposure, at a job or through substantial environmental contact
  • Paraoccupational exposure – exposure to asbestos fibers brought into homes on shoes, clothing, skin and hair of workers

libby montana
Libby, Montana

http://en.wikipedia.org/wiki/Libby,_Montana

libby montana23
Libby, Montana
  • Mining began in 1920
    • W.R. Grace 1963-1990
  • Vermiculite Mines
    • Found in ores and rocks
  • 1979-1998
    • Libby mortality rates: 40 times higher than the rest of Montana and 60 times the national rate
  • 1999
    • EPA begins to respond to local health concerns
    • ATSDR sets up a screening center in Libby

http://www.atsdr.cdc.gov/asbestos/vermiculite_overview.html

what s different about libby
What’s different about Libby?
  • Most vermiculite does not contain detectable levels of asbestos…the vermiculite in Libby does
  • Vermiculite “pops” when heated
  • Libby supplied 80% of vermiculite used worldwide
  • Libby sits in the Kootenai River Valley
  • Environmental exposure a significant cause of the illness in Libby

http://www.atsdr.cdc.gov/asbestos/libby_gallery/frameset.html

prevention
Prevention
  • Avoid exposure

Identify asbestos – kits, professionals

Have it removed or contained

Stay away if friable

  • Stop smoking, avoid 2nd hand smoke, pulmonary sensitizers and irritants
  • Get regular medical care

http://www.poy.org/59/16/1601plonb05.html

http://www.sign.co.za/P1.htm

diagnosis
Diagnosis
  • Abnormal lung function – crackles with stethoscope
  • Chest X-ray
  • CT Scan
  • Biopsy
  • History of Exposure

http://www/shands.org/health/imagepages/1628.htm

http://www.strokecenter.org/pat/diagnosis/ct.htm

treatment
Treatment

Non-malignant disease - Asbestosis:

  • No cure
  • Treatment involves preventing further complications and treating the symptoms
  • Prevent further exposure
  • Stop smoking!!!!
  • Vaccinations – flu and pneumonia
  • Medications – hypertension, blood thinners, pain
  • Supplemental oxygen – makes breathing easier
  • Lung transplant
treatment28
Treatment
  • Malignant disease:
    • Resection (surgical removal of a part)
    • Chemotherapy
    • Radiation

fact or myth

Fact or Myth?

You can tell that a material contains asbestos just by looking at it.

slide30

Fact

It is not possible to tell if something contains asbestos just by looking at it. The only way to tell for sure if a material contains asbestos is to have a sample of it tested at a lab.

fact or myth31

Fact or Myth?

A common end result of asbestos related disease is difficulty breathing.

fact or myth32

Fact or Myth?

The symptoms of asbestos disease will begin to appear immediately or soon after exposure.

slide33

Fact

The latency period for the development of asbestos disease is generally 10-40 years after the initial exposure.
