What does NYSDOL classify as Class One asbestos work?

Class One asbestos work, as defined by the New York State Department of Labor (NYSDOL), pertains specifically to the abatement of thermal system insulation (TSI) and presuming asbestos-containing material (PACM). This classification is critical because it involves procedures that significantly disrupt materials containing asbestos, requiring the highest level of precautions and protections for worker safety due to the potential for asbestos fibers to become airborne and pose health risks.

In the context of this classification, abatement is an active process. It encompasses activities such as the removal, encapsulation, or enclosure of asbestos-containing materials, particularly those known to be present in insulation products used in heating systems and other areas requiring thermal protection. Given the high risk associated with Class One work, rigorous training and comprehensive safety measures are mandated.

The other choices, while related to asbestos work, do not fall under Class One as defined by NYSDOL. Disturbance of ACM (asbestos-containing material) is broader and can apply to various asbestos-related activities but does not specify the abatement of TSI or PACM. Similarly, surveying suspected materials is a preparatory activity aimed at identifying asbestos presence, while final clearance air sampling is a process conducted after abatement to ensure that the area is safe for
