What does Class I asbestos work involve?

Class I asbestos work specifically refers to activities that involve the removal of thermal system insulation (TSI) and surfacing asbestos-containing materials (ACM). This classification is crucial as it addresses the most hazardous types of asbestos-related work due to the friable nature of TSI and surfacing materials, which can release asbestos fibers into the air when disturbed.

The focus on removing TSI and surfacing ACM is driven by the significant health risks associated with exposure to airborne asbestos fibers. Workers engaged in Class I operations are required to follow stringent safety protocols, including the use of specialized containment measures and personal protective equipment to prevent asbestos exposure and contamination.

In contrast, other classifications of asbestos work focus on different types of materials or less hazardous activities. For instance, the encapsulation of non-friable asbestos does not fall under Class I, as it involves managing asbestos without the intention of removal. Similarly, inspections and other forms of non-removal work or handling materials that are not classified as TSI or surfacing ACM are categorized differently due to their lower risk level.
