Which of the following are the three types of evidence?

The question is testing how evidence is categorized at hazmat scenes. The three types are direct, physical, and transient. Direct evidence is information that establishes a fact without needing inference—things you can observe or identify at the scene that point to the hazard, such as properly labeled containers, placards, or shipping papers. Physical evidence consists of tangible items from the scene that can be collected and analyzed, like the actual chemical container, packaging, or samples. Transient evidence refers to temporary conditions that can change or disappear quickly, such as odors, vapors, heat or smoke, color changes, or wind patterns; these require rapid documentation and preservation because they may not be available later. These three categories cover the main ways responders learn what they're dealing with and decide on protective actions. Other terms like photographic documentation or anecdotal reports are methods of recording or sources of information, but they aren’t the primary three types of evidence used in this framework.
