Which measurement system is NOT utilized in documenting a fire scene?

The angular displacement system is not commonly utilized in documenting a fire scene. In the context of fire investigations, accurate scene documentation is crucial to establish the origins and spread of the fire. Investigators typically rely on systems such as the coordinate system, baseline system, and triangulation system, which provide effective methods for measuring and recording specific locations and distances within the scene.

The coordinate system allows for the establishment of a grid that can help pinpoint exact locations, while the baseline system is effective for measuring distances from a fixed reference point. The triangulation system involves using two known points to create a triangle from which all other points can be referenced, aiding in precise documentation.

Conversely, the angular displacement system is more relevant to specific technical applications, such as engineering or physics, rather than the practical needs of fire scene documentation. This lack of relevance to fire investigation results in it not being a standard measurement system used by fire investigators.
