What is the primary difference between Type I and Type II asbestos work?

The primary difference between Type I and Type II asbestos work lies in the nature of the asbestos-containing materials (ACM) being handled. Type I work specifically addresses non-friable ACM, which means that the material is solid and cannot release fibers into the air unless it is subjected to grinding, cutting, or demolition tasks. This includes materials like floor tiles, asphalt roofing, or certain types of insulation. On the other hand, Type II work involves friable ACM, which can easily crumble and release asbestos fibers when disturbed. This type includes materials like sprayed-on insulation or ceiling tiles that can be damaged through minimal handling.

Understanding this distinction is crucial for compliance with regulations and for ensuring the safety of workers and occupants in environments where asbestos is present. The other options do not accurately reflect this critical difference: the first inaccurately attributes the handling of friable and non-friable materials to the wrong types, while the second misidentifies the nature of the work done under each type. The last option erroneously categorizes Type I and Type II work based on property type rather than the material characteristics.
