asbestos shingle inspector Interview Questions and Answers

1. What is asbestos?

   • Answer: Asbestos is a naturally occurring fibrous mineral that was once widely used in construction materials due to its strength and fire resistance. However, it's now known to be a serious health hazard when its fibers are inhaled.

2. What are the health risks associated with asbestos exposure?

   • Answer: Inhaling asbestos fibers can lead to serious lung diseases, including asbestosis (scarring of the lungs), lung cancer, and mesothelioma (a rare and aggressive cancer of the lining of the lungs or abdomen).

3. What types of asbestos were commonly used in shingles?

   • Answer: Chrysotile (white asbestos) was the most common type used in asbestos shingles.

4. How can you identify asbestos shingles?

   • Answer: Visual inspection can sometimes suggest the presence of asbestos, but it's not definitive. Shingles containing asbestos often have a textured surface and may be somewhat brittle. However, definitive identification requires laboratory analysis of a sample.

5. Describe the proper procedures for sampling asbestos shingles.

   • Answer: Sampling must be done by a trained and certified asbestos professional following strict safety protocols. This includes wearing appropriate personal protective equipment (PPE), such as a respirator, gloves, and protective clothing, and using proper sampling techniques to avoid fiber release.

6. What safety precautions must be taken when inspecting asbestos shingles?

   • Answer: Always wear appropriate PPE, including a respirator, gloves, and eye protection. Minimize disturbance of the shingles to reduce fiber release. Properly dispose of any samples according to regulations.

7. Explain the difference between friable and non-friable asbestos.

   • Answer: Friable asbestos is easily crumbled or pulverized, posing a greater risk of fiber release. Non-friable asbestos is bound in a matrix and less likely to release fibers.

8. What are the legal requirements for asbestos abatement?

   • Answer: Asbestos abatement is heavily regulated. Requirements vary by location but generally involve notifying the relevant authorities, using licensed and trained abatement contractors, and following specific procedures for removal and disposal.

9. What is the role of an asbestos inspector?

    • Answer: Cracking, crumbling, significant wear, and damage from weather or impact can increase the risk of fiber release.

12. How do you determine the appropriate sampling strategy for asbestos shingles?

    • Answer: The sampling strategy depends on factors such as the size and condition of the roof, the suspected location of asbestos, and the regulatory requirements. A professional judgment must be made.
