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

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 | 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 | 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

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
