Asbestos Hazards and Controls Exam
Questions With 100% Verified Answers
What is asbestos? -
correct answer ✅Asbestos is a generic term used to describe a
family of naturally occurring silicate minerals that are fibrous. These
minerals are extremely strong, chemically inert, and heat resistant.
Because of these valuable characteristics, asbestos is used to
manufacture many commercial and household products, including
building materials, thermal insulator,, friction production,
reinforcement for cement and plastics, and is even woven into
fabrics..
How is asbestos produced? -
correct answer ✅Asbestos is naturally found in rock deposits and
is mined from the earth by open pit mining. The rocks are
transported to asbestos mills, where the asbestos is extracted from
the rocks. The asbestos is subsequently supplied to manufacturers,
where it is transformed into different products. Asbestos was
widely utilized until the 1980s, when its dangers were discovered.
Since then, most countries have introduced regulations to control
or prohibit the use of asbestos.
Why is asbestos dangerous? -
correct answer ✅Asbestos is a known human carcinogen (a
substance capable of causing cancer. Asbestos fibers can cause
severe illness like lung cancer, asbestosis, and mesothelioma upon

exposure. All of these illnesses are life-threatening. Although the
use of asbestos has reduced significantly in recent years, it can still
be found in many homes and commercial buildings and pose a
health concern to people.
Six main types of asbestos minerals -
correct answer ✅White Asbestos - Chrysotile, is the most
commonly used type of asbestos. It has a white to greenish-grey
color depending on the impurities present. Chrysotile fibers are
very strong, flexible, wavy, easily separable, and with a silky luster.
Chrysotile fibers are rarely brittle. Actinolite, Anthophyllite, and
Tremotlite are the other three types of asbestos. They are not
generally used in the manufacturing of commercially available
products.
Blue asbestos - Crocidolite is lavender-grey to bluish-green with
thin, straight, and sharp fibers. It is weaker than other types and
can be easily broken and inhaled. Blue asbestos is the most
dangerous type and is no longer produced.A
Brown asbestos - Amosite, is a grey-brown and has long fibers that
are harsh and brittle. It has excellent heat resistance and possesses
extreme insulation properties. It is known to be the second most
used type of asbestos.

Asbestos Containing Material (ACM) -
correct answer ✅ACM means any material containing more than
1% asbestos. Since asbestos was widely used till the 1980s as a
thermal insulator and surfacing material, any thermal system
insulation and surfacing material found in building constructed no
later than 1980 is wondered "Presumed Asbestos Containing
Material (PACM)
Which of the following is the most commonly used type of
asbestos? -
correct answer ✅White asbestos
Which type of asbestos is considered most dangerous? -
correct answer ✅Blue asbestos
Hazard Properties of Asbestos -
correct answer ✅Asbestos minerals have many useful properties
that make them suitable for industrial applications. Those
properties include resistance to chemical and biological
degradation, thermal and electrical insulation, wear and friction
characteristics, mechanical strength, and the ability to be woven.
However the hazardous properties of asbestos minerals outweigh
all of the they're useful properties.
