asbestos remover Interview Questions and Answers
-
What is asbestos?
- Answer: Asbestos is a naturally occurring fibrous mineral that was once widely used in building materials due to its strength and heat resistance. However, inhaling asbestos fibers can cause serious lung diseases like asbestosis, lung cancer, and mesothelioma.
-
What are the different types of asbestos?
- Answer: Common types include chrysotile (white asbestos), amosite (brown asbestos), crocidolite (blue asbestos), tremolite, actinolite, and anthophyllite. Chrysotile is the most common type historically used.

Describe the health risks associated with asbestos exposure.
- Answer: Exposure can lead to asbestosis (scarring of the lungs), lung cancer, mesothelioma (cancer of the lining of the lungs or abdomen), and pleural diseases (thickening of the lung lining). The severity depends on the intensity and duration of exposure.
