In fire investigation, what is the minimum drawing requirement?

In fire investigation, the minimum drawing requirement is a simple sketch. This is essential for documenting the scene effectively. A simple sketch allows investigators to accurately represent the layout of the area where the fire occurred, including important landmarks, the location of the fire's origin, and the placement of various items. This form of documentation is critical in helping to visualize the scene and can provide valuable context when analyzing fire patterns, potential causes, and the sequence of events during the incident.

While more detailed depictions such as blueprints, photographs, or three-dimensional models can certainly enhance an investigation, the straightforward and quick nature of a simple sketch meets the basic need for initial documentation. It is especially useful in situations where time is of the essence, allowing investigators to capture the necessary details quickly before evidence can be removed or altered.
