The sample taken from material to determine asbestos content is called:

• A. Air Sample
• B. Surface Sample
• C. Bulk Sample
• D. Wipe Sample

Answer: (C)

The main idea is identifying the type of sample used to determine the asbestos content of a material itself. When you need to know how much asbestos is actually in a material, you take a piece of the material itself and send it to a lab for analysis. This is called a bulk sample. It provides a direct measurement of asbestos content in the material, which is essential for deciding how to handle or remediate it and for meeting regulatory requirements. Air samples, by contrast, measure asbestos fibers that are present in the air you could inhale, not the material’s content. Surface or wipe samples collect dust or fibers on surfaces to assess contamination after work or cleaning activities. These serve exposure or contamination assessments rather than determining the material’s asbestos content.
