What does the term 'leak-tight' mean in asbestos containment?

The term 'leak-tight' in asbestos containment specifically refers to the ability of materials to securely contain both solids and liquids without any escape. It emphasizes that within an asbestos containment setup, all materials that could potentially release asbestos fibers or hazardous substances are designed to prevent any leakage. This is critical in protecting the environment and human health, as even minor leaks can pose significant risks regarding asbestos exposure.

In situations involving asbestos, maintaining a leak-tight environment is essential to prevent contamination and ensure that any airborne fibers or hazardous materials are contained. The definition reflects the stringent requirements for safety and compliance in asbestos management, where integrity of containment systems is paramount.

Other options either suggest methods of inspection, temporary solutions, or partial containment, which do not meet the strict standards implied by 'leak-tight.' This term unequivocally denotes a complete and secure containment strategy, making option B the most appropriate choice.
