New York State Asbestos Investigator Practice Exam

What does Class I OSHA work classification involve?

1. Removal of miscellaneous materials

2. Repair and maintenance operations

3. Removal of TSI and surfacing ACM or PACM

4. Cleaning up asbestos spills

The correct answer is: Removal of TSI and surfacing ACM or PACM

Class I OSHA work classification specifically refers to the removal of thermal system insulation (TSI) and surfacing asbestos-containing material (ACM) or presumed asbestos-containing material (PACM). This classification is crucial because it addresses the most hazardous types of asbestos work, where exposure risk tends to be the highest due to the friable nature of the material, which can easily release asbestos fibers into the air. The distinction made in Class I work emphasizes the significant safety measures and handling protocols required when dealing with these particular materials, given their potential to pose serious health risks if not managed correctly. Regulations and standards apply to ensure that workers are protected through the use of appropriate personal protective equipment (PPE), containment methods, and environmental controls during these operations. Understanding this classification is fundamental for any asbestos investigator or professional working in the field, as it informs the guidelines and best practices for handling highly dangerous asbestos materials.
