Background
© 2020 WESTECH | 5
Asbestos
▪A generic name given to naturally-
occurring, fibrous minerals
▪Comes from the ancient Greek word
ἄσβεστος, meaning "unquenchable"
or "inextinguishable"
© 2020 WESTECH | 6
Asbestos ▪First recorded use more than 4,500
years ago
▪Greeks used in pottery, wicks,
funeral dresses and as napkins
▪Egyptian pharaohs were wrapped in
asbestos cloth
▪Romans used in building materials
2,000 years ago
▪Large-scale use not until the end of
the 19th century

Asbestos Definitions
▪ ACM: Asbestos-containing material
▪ ACBM: Asbestos-containing building
material
▪ Friable: Can be crumbled, pulverized or
reduced to powder by hand pressure
▪ Regulated ACM: Friable ACM or non-friable
ACM that will become friable
▪ Asbestos-containing material (ACM) - any
material that contains greater than 1%
asbestos
▪ Trace amounts of asbestos - materials
containing 1% or less of asbestos

Uses of Asbestos
▪Mined and used commercially in
beginning in the late 1800s
▪Use increased greatly during
World War II
▪Peak use in 1973
▪More than 5,000 products contain
or have contained asbestos
In the United States

Asbestos Bans
▪1973: EPA bans spray-on
fireproofing/insulation
▪1975: EPA bans pipe insulation
▪1989: EPA bans most ACM
▪1991: Bans overturned by courts
▪Few uses banned in the USo Floor felt
o Rollboard
o Corrugated, commercial and
specialty paper
o New uses (after 1989)
▪No bans on imported materials

Exposure & Health Effects
© 2020 WESTECH | 37
Why Care ▪Body cannot break down asbestos
fibers or remove them once they are
lodged in body tissues
▪The fibers remain in the body where
they cause disease
▪Diseases associated with asbestos
exposure: Asbestosis, Mesothelioma,
asbestos-related lung cancer, pleural
plaques/thickening
▪Routes of Exposure: Inhalation &
Ingestion

Health Effects

Health Effects ▪No “safe” level of asbestos
exposure
Everyone is exposed to asbestos at some time
during their life. Low levels of asbestos are
present in the air, water and soil. However, most
people do not become ill from their exposure.
People who become ill from asbestos are usually
those who are exposed to it on a regular basis,
most often in a job where they work directly with
the material or through substantial environmental
contact.

Health Effects
Determining Factors for
Developing Disease
▪ The amount and duration of exposure.
▪ Whether you smoke.
▪ Smoking increases the risk of developing
asbestos-related cancer by a factor of 50%
to 90%

Health Effects
World Trade Center
▪The collapse of the World Trade
Center Towers released an
estimated 2,000 tons of asbestos

Health Effects
Libby, Montana
▪ One of the largest asbestos exposure
cases in U.S. history occurred at a
vermiculite mine near Libby, Montana.
The Libby mine opened in 1921 and
once accounted for almost 80 percent of
the world’s vermiculite production.
▪ The mine closed in 1990.

Health Effects Talcum Powder
▪Talcum powder is made from talc,
a mineral
▪ In its natural form, some talc
contains asbestos
© 2020 WESTECH | 55
Asbestos Exposure
▪Knowledge is Goodo Asbestos inspection
▪Good Work Practiceso Avoid disturbing ACM
o Never drill, hammer, cut, saw,
break, burn or scrape ACM
o Do not attempt to clean friable
ACM
▪Personal Protective Equipment

Detection & Assessment
© 2020 WESTECH | 58
ACM Determination
▪Two Choices:1. Collect and analyze samples
2. Assume ACM
© 2020 WESTECH | 59
ACM Determination ▪Cannot see asbestos fibers with
naked eye
▪More then one sample is required
to determine non-ACM
▪Must be certified state to collect
samples
© 2020 WESTECH | 60
ACM Determination
Comprehensive vs.
Limited Asbestos Inspections
© 2020 WESTECH | 61
ACM Determination
Asbestos Inspection Report:
▪ Types of suspected ACM
▪ Sample data
▪ ACM / Non-ACM Determination
▪ Location and quantity of ACM
▪ Type of ACM (friable or non-friable)
Inspection Cost (typically): $1,000
to $10,000

Summary
▪ACM can be in a variety of building
materials
▪Friable ACM poses potential risk of
exposure
▪ACM can remain in buildings and
long it is in good condition and not
disturbed
▪Asbestos inspection required prior to
renovation and demolition
(regardless of age of building)
▪Only trained personnel can conduct
asbestos work
▪Asbestos should be respected not
feared
