Which aspect is true regarding the relationship between class I and class II works?

The correct choice highlights that Class II work specifically involves the removal of asbestos-containing materials that are not categorized as thermal insulation or surfacing materials. This distinction is important because it underscores the specific types of asbestos materials that fall under Class II regulations, which include materials that may be less dangerous compared to those in Class I but still require careful handling and removal processes.

Understanding this classification helps workers identify the nature of the materials they are dealing with and the appropriate precautions that must be taken during removal or renovation activities. Class I deals primarily with the most hazardous materials like thermal insulation and surfacing materials, while Class II covers other types that are still significant but may not pose the same level of risk when managed properly.

Other answer choices do not accurately reflect the classifications or their definitions, which is critical for ensuring safe handling and compliance with regulatory standards in asbestos management.
