Which of the following is required for proper glove bag procedures?

The requirement for using a HEPA vacuum to evacuate air from the glove bag is essential for ensuring safety and minimizing the risk of asbestos exposure during abatement activities. A HEPA (High-Efficiency Particulate Air) vacuum is designed to filter out 99.97% of particles that are 0.3 microns in size, which is crucial for capturing asbestos fibers that may be released into the air. By evacuating air and potentially hazardous particles from the glove bag, this practice helps to maintain a controlled environment, preventing the spread of asbestos and protecting both the worker and surrounding areas.

In addition to using a HEPA vacuum, proper glove bag procedures also involve other measures such as ensuring that the glove bag is adequately sealed to prevent leaks and following specific protocols for handling and disposing of asbestos-containing materials. While there might be a necessity to have personnel present to manage the operation, relying solely on visual inspections does not provide the same level of safety assurance as utilizing filtration systems like a HEPA vacuum. The focus on air evacuation with proper filtration is a critical step in safe asbestos abatement practices.
