What is defined as Class I asbestos work?

Class I asbestos work specifically refers to activities involving the removal of thermal system insulation (TSI) and surfacing asbestos-containing material (ACM) and presumed asbestos-containing material (PACM). This type of work is classified as high risk due to the potential for significant exposure to airborne asbestos fibers, which can pose severe health risks.

Professionals engaged in Class I asbestos work must adhere to stringent safety regulations and guidelines because the disturbance of these materials can release harmful asbestos fibers into the air. Consequently, workers are required to use specialized training, personal protective equipment (PPE), and follow strict protocols to effectively manage and mitigate risks associated with asbestos exposure.

This definition emphasizes the critical nature of Class I work, distinguishing it from activities like minor repairs or maintenance tasks involving nonfriable asbestos, which do not involve the high levels of risk associated with the removal of TSI or surfacing materials. The distinction is significant for workers and safety regulators when establishing appropriate training and safety measures to protect both workers and the public from the dangers posed by asbestos.
