What is essential to ensure during glove bag operations?

During glove bag operations, sealing the glove bag airtight is crucial for maintaining safety and minimizing the release of asbestos fibers into the environment. A properly sealed glove bag prevents airborne contamination and ensures that any asbestos-containing material that is disturbed during the operation remains contained. This containment is vital in protecting the health of workers and preventing exposure to the surrounding area.

The other options involve practices that do not align with the safety protocols for glove bag operations. Limiting the operation to one worker may not be practical, as team dynamics and safety checks are essential during such hazardous work. Disposing of materials within 24 hours is not a standard requirement; rather, safe disposal follows regulatory guidelines that ensure materials are handled appropriately based on local regulations. Lastly, post-operation testing is a critical step in confirming that the work area is safe and free from asbestos fibers before reopening it to general occupancy, so dismissing testing is not in line with best practices or legal requirements.
