What is a "crack" in the context of packaging integrity?

In the context of packaging integrity, a "crack" refers specifically to a narrow split or break in the packaging material. This definition is crucial in hazardous materials handling, as even small breaches in packaging can lead to potential leaks or the release of hazardous substances. A crack indicates a compromise in the material that, while not necessarily catastrophic, still poses a risk for exposure to the contents inside the package.

Understanding the implications of a crack is vital in assessing the overall safety and integrity of the packaging. For example, a small crack might not be as evident as a large break, but it can allow substances to escape over time, especially under pressure or temperature fluctuations. Hence, identifying and addressing even small defects such as cracks is critical in ensuring safe storage and transport of hazardous materials.
