Asbestos Contractor/Supervisor Practice Exam

Which of the following asbestos-containing materials is considered an OSHA Class II job during removal?

1. Pipe insulation with a torn jacket inside a classroom

2. Floor tiles

3. Roofing shingles

4. Acoustic ceiling tiles

The correct answer is: Pipe insulation with a torn jacket inside a classroom

The correct answer pertains to the classification of asbestos-containing materials for removal by OSHA, specifically regarding Class II jobs. A Class II job is defined as the removal of materials that contain asbestos that are not thermal system insulation or surfacing material. In this case, pipe insulation typically falls under the category of thermal insulation and typically would not qualify as a Class II job when it is intact. However, when the insulation has a torn jacket, it may expose the underlying asbestos and could require a more controlled removal process which can bring it under the scope of a Class II job. In contrast, floor tiles, roofing shingles, and acoustic ceiling tiles are materials that, when removed, generally fall under the Class II category. However, the context suggests that the torn jacket on the pipe insulation necessitates careful handling akin to that of Class II, particularly since its integrity is compromised. This means that even though the material is technically insulation, the state of the material elevates it to a Class II level due to potential release of asbestos fibers during the removal process. Thus, the correct answer is justified as it reflects the specific circumstances that classify the material's removal type, considering the risk presented by the damaged condition of the pipe insulation.
