Asbestos Training Questions and All
Correct Answers 2025-2026 Updated.
Three types/forms of asbestos - Answer Chrysotile (white): Most Common,
Amosite (brown): Most Dangerous,
Crocidolite (blue) : Rare
What is the name and color of the most commonly found type that is present in asbestos
materials - Answer Chrysotile (white)
What color is amosite and why is it more dangerous than the other forms of asbestos - Answer
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 - Answer 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 - Answer 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 - Answer No (not friable)
Is TSI (Thermal System Insulation) friable or non-friable under normal conditions - Answer
Yes (is friable)
Is Plaster friable or non-friable under normal conditions - Answer no (not friable)
How can one determine if a building material contains asbestos - Answer 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 - Answer 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 - Answer 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 -
Answer An accredited lab
According to EPA and OSHA, asbestos containing materials contains how much asbestos by
weight - Answer Greater than 1% asbestos by weight
Currently how many products/ building materials contain asbestos - Answer 3,000-4,000
products
When/ which year was spray-applied and TSI application/installation of asbestos banned -
Answer 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 - Answer 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 - Answer 32
hours
What are the EPA regulations for 1) asbestos located in schools and buildings and 2) public
buildings and commercial properties - Answer 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 - Answer
1. Removal-Permanently gets rid of the asbestos
2. Encapsulation- Covers or soaks into the material thereby preventing a river release
3. Enclosure- Covers/encloses the material
