What is the name and color of the most commonly found type that is
present in asbestos materials correct answers Chrysotile (white)
What color is amosite and why is it more dangerous than the other forms of
asbestos correct answers Brown; it's needle like structure and that the fact
it is very hard to wet, making it the most dangerous type/form
What are the properties of asbestos correct answers 1. Has a high tensile
strength (10 X greater than steel)
2. Won't conduct electricity
3. It has good insulation capabilities
4.Has acoustical/ soundproofing capabilities 5. Is resistant to heat,
chemicals, friction and wear
6. Won't burn
What is the definition of friable correct answers Able to crumble or
crush by hand pressure or easily mechanically into a dust/powder
when dry
Is Floor Tile friable or non-friable under normal conditions correct
answers No (not friable)
Is TSI (Thermal System Insulation) friable or non-friable under normal
conditions correct answers Yes (is friable)
Is Plaster friable or non-friable under normal conditions correct answers no
(not friable)
How can one determine if a building material contains asbestos correct
answers A bulk sample must be collected and submitted to a lab for analysis
by polarized light microscopy (PLM) analysis. A material that is equal to or
greater than 1% asbestos by weight is positive for asbestos
What is the name of the lab test used for bulk sample analysis correct
answers Polarized Light Microscopy (PLM) this method tells the %
(amount) asbestos content and the type/form present in the sample
, What is the names of the lab tests used for air sample correct answers
Phase Contrast Microscopy (PCM) and Transmission Electron Microscopy
(TEM)
According to the regulations, who is authorized to perform the lab tests
indicated in H & I correct answers An accredited lab
According to EPA and OSHA, asbestos containing materials contains
how much asbestos by weight correct answers Greater than 1%
asbestos by weight
Currently how many products/ building materials contain asbestos
correct answers 3,000-4,000 products
When/ which year was spray-applied and TSI application/installation of
asbestos banned correct answers 1978
According to the OSHA Construction Standard for Asbestos, how many
asbestos activities are there and what are the training requirements for
workers for each activity correct answers 1. Class 1- Activities that involve
the removal of TSI and surfacing materials; 32 hours
2.Class 2- Activities that involve the removal of miscellaneous
materials (materials that's are not TSI and Surfacing Materials); 32 hours
3. Class 3- Operation and maintenance activities; 16 hours
4.Class 4 - Custodial/ housekeeping activities; 2 hour
awareness (supervisor/competent person- 40 hours for
each class)
What is the minimum number of training hours to become a abatement
worker correct answers 32 hours
What are the EPA regulations for 1) asbestos located in schools and
buildings and 2) public buildings and commercial properties correct
answers 1. Schools- Asbestos Hazard Emergency Response Act (AHERA)
2. Public/Commercial- National Emission Standard for Hazardous Air
Pollutants (NESHAP)
List asbestos control methods and describe the advantages and
disadvantages of each correct answers 1. Removal-Permanently gets rid of
the asbestos
5. Encapsulation- Covers or soaks into the material thereby preventing a
river release
6. Enclosure- Covers/encloses the material
7.Repair- Allows for small amounts to be permanently removed thereby
controlling the potential for release
8. Operating/ Maintenance- control method that allows the owner to operate
the building
with asbestos in the building while maintaining the material in good
condition
According to your state regulations how many days notification must be
provided to the state prior to beginning an asbestos project correct answers
