What must glovebags be subjected to before use?

The correct process that glovebags must be subjected to before use is pressure testing. Pressure testing ensures that the glovebag is airtight and can effectively contain any potentially harmful asbestos fibers during removal or handling procedures. This is crucial for maintaining a safe work environment and preventing asbestos exposure.

Visual inspections are also important to check for any obvious defects before use, but they do not guarantee that the glovebag can withstand the necessary pressure during its operation. Smoke testing, which involves using smoke to detect leaks, is not a standard procedure for glovebags. Water testing is similarly not relevant in this context as it does not relate to the performance requirements of a glovebag that is meant to contain airborne particles.

Ultimately, pressure testing is essential as it confirms the structural integrity and functionality of the glovebag, ensuring compliance with safety standards in environments where asbestos is present.
