asbestos surveyor 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, heat resistance, and fire-retardant properties. There are six types of asbestos, each with varying degrees of harmfulness. However, all forms of asbestos pose a significant health risk when their 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, mesothelioma (a rare and aggressive cancer of the lining of the lungs or abdomen), and pleural diseases (thickening or scarring of the lining of the lungs).

3. Describe the different types of asbestos.

   • Answer: The six types are chrysotile (white asbestos), crocidolite (blue asbestos), amosite (brown asbestos), tremolite, actinolite, and anthophyllite. Chrysotile is the most common type historically used, but all pose health risks.

4. What are the common materials containing asbestos?

   • Answer: Asbestos was used in a wide range of building materials, including insulation (pipe lagging, sprayed coatings), ceiling tiles, floor tiles, textured paints, cement products (roofing felt, asbestos cement sheets), and fire-resistant materials.

5. Explain the process of conducting an asbestos survey.

   • Answer: An asbestos survey involves a visual inspection of the building, identifying materials that may contain asbestos, sampling suspected materials, and laboratory analysis to confirm the presence and type of asbestos. The process is documented in a detailed report.

6. What are the different types of asbestos surveys?

   • Answer: There are typically two types: a Type 1 survey (management survey) which is a visual inspection to identify the presence and location of asbestos containing materials (ACMs); and a Type 2 survey (remedial survey) which is a more detailed intrusive investigation to identify, locate and quantify ACMs prior to demolition or refurbishment.

7. What safety precautions are necessary when conducting an asbestos survey?

   • Answer: Surveyors must wear appropriate personal protective equipment (PPE), including respirators, coveralls, gloves, and eye protection. Air monitoring may be required, and all work must be carried out in accordance with relevant health and safety regulations.

8. How are asbestos samples collected and analyzed?

   • Answer: Samples are carefully collected using specialized techniques to avoid fiber release. They are then sent to a UKAS accredited laboratory for analysis using polarized light microscopy (PLM) or transmission electron microscopy (TEM).

9. What is the role of a competent person in asbestos work?

   • Answer: A competent person is an individual with the necessary training, experience, and qualifications to supervise and manage asbestos-related work safely and in accordance with regulations.

10. What are the legal requirements for managing asbestos in buildings?

    • Answer: Legal requirements vary by country and region but generally involve identifying and managing asbestos-containing materials to prevent exposure and ensure the safety of building occupants and workers. This often involves keeping an asbestos register and complying with regulations regarding removal and refurbishment.

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

    • Answer: Friable asbestos is easily crumbled or reduced to powder, posing a higher risk of fiber release. Non-friable asbestos is more stable and less likely to release fibers unless damaged.

12. What are the different methods for asbestos abatement?

    • Answer: Abatement methods include encapsulation (sealing ACMs in place), enclosure (creating a barrier around ACMs), and removal (complete removal of ACMs). The chosen method depends on the type of ACM, its condition, and location.

13. What is an asbestos register? Why is it important?

    • Answer: An asbestos register is a document that records the location and type of ACMs found in a building. It’s crucial for managing asbestos safely, informing stakeholders, and preventing accidental exposure during maintenance or refurbishment.

14. What are the key aspects of an asbestos management plan?

    • Answer: A management plan details how asbestos will be managed throughout the building's lifecycle. This includes identifying ACMs, assessing risks, developing control measures, monitoring the condition of ACMs, and outlining procedures for repairs and refurbishment.

15. Describe your experience with different types of asbestos-containing materials.

    • Answer: (This requires a personalized answer based on the candidate's experience. They should describe specific materials encountered, such as sprayed asbestos insulation, asbestos cement sheets, textured coatings, etc.)

16. How do you handle unexpected asbestos discoveries during a survey?

    • Answer: Immediately cease work, isolate the area, inform relevant stakeholders, and follow established protocols for managing unexpected asbestos findings. This may involve further sampling and analysis, and revising the survey report.

17. What are the key regulations and standards that you follow in your work?

    • Answer: (This answer will vary by location but should include relevant national and local regulations, and standards such as HSE guidance in the UK, or equivalent regulations in other countries.)

18. How do you ensure the accuracy and reliability of your survey reports?

    • Answer: Through meticulous record-keeping, clear photographic evidence, accurate sampling techniques, and the use of UKAS accredited laboratories for analysis. Regular calibration of equipment and adherence to strict quality control procedures are also crucial.

19. How do you communicate your findings to clients and other stakeholders?

    • Answer: Clearly and concisely, using plain language, avoiding technical jargon, and providing visual aids (maps, photos) to illustrate findings. A detailed written report is provided, and verbal explanations are given to ensure understanding.

20. Describe a challenging situation you faced during an asbestos survey and how you overcame it.

    • Answer: (This requires a personalized answer describing a specific challenging situation and the steps taken to resolve it. Examples could include difficult access, unexpected asbestos types, or client communication challenges.)

21. What are your professional development plans regarding asbestos surveying?

    • Answer: (This should detail plans for continued professional development, such as attending training courses, staying up-to-date with regulations, and maintaining professional certifications.)

22. What software or tools do you use in your work?

    • Answer: (This should list relevant software for report writing, data management, mapping, and potentially air monitoring data analysis.)

23. What is your understanding of the different methods of asbestos removal?

    • Answer: Detailed knowledge of different removal methods, including their suitability for various asbestos types and locations. Understanding of the importance of using licensed and competent contractors for asbestos removal.

24. How do you ensure compliance with health and safety regulations during asbestos surveys?

    • Answer: By meticulously following all relevant health and safety regulations, using appropriate PPE, implementing risk assessments, and ensuring proper training for all involved. Understanding of emergency procedures and reporting requirements.

25. What is your experience with air monitoring during asbestos work?

    • Answer: (This requires an answer detailing experience with air monitoring equipment, procedures, and interpretation of results. It should explain how air monitoring data informs decisions on control measures.)

26. How do you manage potential conflicts of interest in your work?

    • Answer: By maintaining objectivity, disclosing any potential conflicts, and ensuring that decisions are made based on professional judgment and ethical considerations.

27. What is your understanding of the Control of Asbestos Regulations (or equivalent in your region)?

    • Answer: (This requires a detailed understanding of the relevant regulations. The answer should demonstrate knowledge of key requirements, including responsibilities of duty holders, management procedures, and legal obligations.)

28. How would you explain the importance of asbestos management to a non-technical client?

    • Answer: In plain language, explaining the health risks associated with asbestos exposure, the importance of identifying and managing ACMs to prevent fiber release, and the long-term benefits of responsible asbestos management.
