Removal of friable boiler insulation falls under which class of work?

The correct answer is that the removal of friable boiler insulation falls under Class I work. This classification is important in asbestos management as it pertains to the handling of materials that are highly friable, meaning they can easily crumble and release asbestos fibers into the air.

Class I work specifically involves the removal of asbestos-containing materials (ACMs) that are sprayed or otherwise applied in such a way that they can easily be disturbed, leading to a higher risk of exposure for workers and surrounding environments. Friable boiler insulation is considered more hazardous because when it's disturbed, it releases asbestos fibers that can be inhaled, leading to serious health risks.

Class II work pertains to the removal of non-friable ACMs, which do not easily release fibers and generally pose a lower risk. Class III work involves repair and maintenance activities where ACMs are likely to be disturbed and potentially release fibers, but it does not involve outright removal. Class IV work includes maintenance and custodial activities, which do not involve any disturbance of ACM.

Understanding these classifications is crucial for ensuring safety protocols and regulations are properly followed during asbestos-related work, as different classes require different safety measures and training.
