Which of the following is a characteristic listed for inspecting hazardous materials?

Inspecting hazardous materials involves several critical characteristics that help determine their safety and manageability. Leakage is a primary concern because it indicates that a hazardous substance is escaping from its container. This can lead to contamination, environmental harm, and health risks for individuals nearby. Identifying leaks quickly allows for swift intervention to mitigate the risks associated with hazardous materials.

While the color of the material, temperature, and weight can provide useful information during an inspection, they do not specifically highlight the immediate dangers associated with hazardous substances as clearly as detecting leakage does. Understanding the presence of leakage is essential for ensuring safety protocols are followed and that appropriate responses are taken to protect human health and the environment.
