What must be done prior to the disposal of glovebags?

Prior to the disposal of glovebags, it is essential to remove the air inside using a HEPA vacuum. This step is crucial for several reasons related to safety and containment. By using a HEPA vacuum, any potentially hazardous airborne particles that could have accumulated inside the glovebag are effectively removed. This minimizes the risk of asbestos fibers escaping into the environment during the disposal process, which can pose health risks to both workers and the surrounding area.

Additionally, removing the air helps to compact the materials inside the glovebag, making it easier to seal and store. Proper removal and handling of glovebags are part of a comprehensive approach to asbestos management and demonstrate adherence to safety guidelines designed to limit exposure to hazardous materials.

The other options either do not address the containment of airborne particles effectively or focus on sealing without ensuring that the interior is free from contaminants. For instance, cutting open glovebags could release harmful fibers, and sealing them with duct tape or double-bagging without first removing air does not adequately mitigate the risk of contamination. It is critical to follow proper procedures like vacuuming to maintain safety standards in asbestos handling and disposal.
