What is the purpose of a bulk sample in asbestos testing?

• A. To determine asbestos content in material
• B. To measure airborne asbestos concentration
• C. To assess moisture content
• D. To determine fiber type

Answer: (A)

The main idea is to check the material itself for asbestos content. A bulk sample is taken from the actual building material to determine whether asbestos is present and, if so, roughly how much asbestos is in that material. This information helps decide if the material is asbestos-containing (ACM) and informs what kind of remediation or controls are needed. It’s different from measuring asbestos in the air, which is about exposure rather than the material's composition. Lab analysis may identify the type of asbestos fibers as part of the work, but the primary purpose of a bulk sample is to determine the presence and amount of asbestos in the material. Moisture content isn’t the goal of this test.
