Which of the following is an indication of a possible chemical leak during transport?

Visible damage to packaging is a critical indication of a possible chemical leak during transport. Packaging for hazardous materials is designed to contain and protect the contents from leaks, spills, and contamination. If there is visible damage to the packaging, such as punctures, cracks, or deformation, it suggests that the integrity of the container has been compromised. This can lead to the release of hazardous substances and poses a risk to both the environment and public safety.

Stable temperature readings, increased visibility, and clear atmospheric conditions typically do not indicate a chemical leak. Stable temperature readings may suggest that the material is being transported under controlled conditions, while increased visibility or clear atmospheric conditions do not provide any information about the potential for a leak. Therefore, visible damage to packaging serves as a clear warning sign of potential chemical exposure, making it important for responders to take precautionary measures.
