Is Thermal System Insulation (TSI) friable or non-friable?

Thermal System Insulation (TSI) is categorized as friable because it can crumble or break apart easily, releasing asbestos fibers into the air when disturbed. This characteristic is significant because friable asbestos poses a higher risk of exposure compared to non-friable asbestos, which tends to remain intact and does not easily release fibers unless significantly damaged. In the context of asbestos training, recognizing TSI as friable is critical for understanding the necessary precautions and safety measures required when handling or working near such materials, as any disturbance could lead to inhalation of dangerous asbestos fibers.

Other options might suggest that TSI is non-friable or conditional based on type, but TSI's inherent qualities confirm it is primarily viewed as friable in accordance with safety regulations and guidelines in asbestos training. This understanding is essential for managing potential health risks associated with asbestos exposure.
