What is Asbestos?
http://www-admn.csun.edu/ehos/safeshop/ASBESTOS%20AWARENESS.ppt
 Mineral Fibers
 Long & Thin
 Strong
 Flame/Heat resistant
 Durable
 Friable
 Detectable only with a
microscope

Is Asbestos Still Around?
 Siding and Roofing
 Cement
 Insulation
 Gaskets
 Friction products –
http://www-admn.csun.edu/ehos/safeshop/ASBESTOS%20AWARENESS.ppt
brake pads
 New uses banned in 1989
 Damage to structures

Fibers become airborne
http://www-admn.csun.edu/ehos/safeshop/ASBESTOS%20AWARENESS.ppt
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
 High blood pressure
in your lungs
 Heart problems




Asbestosis
Lung Cancer
Malignant Mesothelioma
Progressive Respiratory
Insufficiency
 Other cancers
Health Hazards of Exposure Pulmonary Hypertension
 Arteries of the lung become
blocked or narrow due to
asbestosis-related scar
tissue.

Health Hazards of Exposure Heart Problems – Cor Pulmonale
 Excess pressure in the
http://health.allrefer.com/health/cor-pulmonale-cor-pulmonale.htl
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 Exposure


High blood pressure in your lungs
Heart problems
 Asbestosis

Lung Cancer
Malignant Mesothelioma
Progressive Respiratory Insufficiency
Other cancers
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 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 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.

in contaminated areas.
Esophagus
Larynx

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
http://en.wikipedia.org/wiki/Libby,_Montana
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



http://www.atsdr.cdc.gov/asbestos/vermiculite_overview.html
EPA begins to respond
to local health concerns
ATSDR sets up a
screening center in
Libby
What’s different about Libby?
 Most vermiculite does not




http://www.atsdr.cdc.gov/asbestos/libby_gallery/frameset.html
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
Prevention
 Avoid exposure
Identify asbestos – kits,
professionals
Have it removed or
contained
Stay away if friable
 Stop smoking, avoid 2nd
http://www.poy.org/59/16/1601plonb05.html
hand smoke, pulmonary
sensitizers and irritants
 Get regular medical
care
http://www.sign.co.za/P1.htm
Diagnosis
 Abnormal lung function




– crackles with
stethoscope
Chest X-ray
CT Scan
Biopsy

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
Treatment
 Malignant disease:



Resection (surgical removal of a part)
Chemotherapy
Radiation

Fact or Myth?
You can tell that a material contains
asbestos just by looking at it.
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 Myth?
A common end result of asbestos related
disease is difficulty breathing.
Fact or Myth?
The symptoms of asbestos
disease will begin to appear
immediately or soon after
exposure.
Fact
The latency period for the
development of asbestos disease is
generally 10-40 years after the
initial exposure.
