Which system is primarily used to protect workers from asbestos fibers during cleanup?

The use of HEPA filtration systems is crucial for protecting workers from asbestos fibers during cleanup operations. HEPA, which stands for High-Efficiency Particulate Air, is a type of air filter that can trap at least 99.97% of particles that are 0.3 micrometers in diameter. Asbestos fibers are known to be microscopic and can pose significant health risks when inhaled; therefore, a filtration system that can effectively capture these tiny particles is essential for maintaining safe air quality.

In environments where asbestos is being disturbed, such as during cleanup or demolition, HEPA filtration systems help to ensure that airborne asbestos fibers are collected and removed from the air. This is especially important because respirable asbestos fibers can remain suspended in the air and pose a risk to workers' health.

While disposable uniforms, ventilation systems, and chemical shielding may all play roles in a comprehensive safety approach, HEPA filtration is specifically designed for effective removal of particulates from the air, making it the primary system relied upon in situations involving exposure to asbestos fibers.
