Class II Asbestos work encompasses the removal of which of the following materials?

Class II Asbestos work specifically pertains to the removal of certain types of asbestos-containing materials (ACM), particularly those that are non-friable. This includes materials like asbestos-containing wallboard and floor tiles. The classification helps to delineate the types of materials and work involved in asbestos abatement, ensuring that appropriate safety guidelines and procedures are followed during the removal process.

In contrast, Class I work addresses the most hazardous materials, such as thermal system insulation and surfacing material, which are typically friable and pose a higher risk of fiber release. Class III work involves repair and maintenance activities that disturb ACM. Class IV work includes custodial activities where ACM might be present but typically does not involve disturbance or removal.

Thus, the correct focus for Class II work on non-friable materials like wallboard and floor tiles aligns with the established definitions and classifications of asbestos work, reaffirming that option B accurately represents the scope of Class II Asbestos work.
