asbestos coverer Interview Questions and Answers

1. What is asbestos?

   • Answer: Asbestos is a naturally occurring mineral fiber that was once widely used in building materials due to its strength and fire resistance. However, it's now known to be a serious health hazard, causing lung diseases like asbestosis, lung cancer, and mesothelioma when its fibers are inhaled.

2. What are the different types of asbestos?

   • Answer: The main types are chrysotile (white asbestos), amosite (brown asbestos), crocidolite (blue asbestos), tremolite, actinolite, and anthophyllite. Chrysotile was the most commonly used.

3. Describe the health risks associated with asbestos exposure.

   • Answer: Inhaling asbestos fibers can lead to asbestosis (scarring of the lungs), lung cancer, and mesothelioma (a rare and aggressive cancer of the lining of the lungs, abdomen, or heart). These diseases often have a long latency period, meaning symptoms may not appear for decades after exposure.

4. What safety precautions are necessary when working with asbestos?

   • Answer: Strict adherence to all relevant regulations and safety protocols is crucial. This includes wearing appropriate PPE (Personal Protective Equipment) such as a respirator, coveralls, gloves, and eye protection; using appropriate containment methods; following proper decontamination procedures; and monitoring air quality.

5. Explain the process of asbestos abatement.

   • Answer: Asbestos abatement involves the safe removal or encapsulation of asbestos-containing materials. This typically involves careful planning, assessment, containment, removal or encapsulation, disposal, and thorough cleaning and air monitoring to ensure worker and public safety.

6. What are the different methods of asbestos abatement?

   • Answer: Common methods include enclosure (covering the asbestos in place), encapsulation (sealing the asbestos with a sealant), and removal (carefully removing and disposing of the asbestos-containing materials).

7. What is the role of air monitoring during asbestos abatement?

   • Answer: Air monitoring measures the concentration of asbestos fibers in the air to ensure that exposure levels remain below the permissible limits, protecting workers and the surrounding environment.

8. What type of respirator is required when working with asbestos?

   • Answer: A properly fitted, NIOSH-approved respirator with HEPA (High-Efficiency Particulate Air) filtration is required. The specific type will depend on the task and concentration of asbestos fibers.

9. Describe the proper disposal procedures for asbestos waste.

   • Answer: Asbestos waste must be properly contained, labeled, and transported to a licensed asbestos disposal facility. Specific regulations vary by location, but double-bagging in heavy-duty plastic bags and secure transport are always crucial.

10. What is asbestos-containing material (ACM)?

    • Answer: ACM refers to any material containing more than a specific percentage of asbestos (this percentage varies by region and regulation). Examples include asbestos cement sheets, sprayed asbestos insulation, and asbestos-containing floor tiles.
