During every fire scene examination, the presence and condition of fuel gas systems need to be what?

The presence and condition of fuel gas systems during a fire scene examination must be examined and documented because they play a crucial role in understanding the cause and behavior of the fire. Fuel gas systems can be potential ignition sources and can significantly impact the fire dynamics, including how the fire spread and the potential hazards that may arise during an investigation. Thorough documentation ensures that investigators can evaluate the systems accurately, consider them in their analysis, and provide comprehensive reports.

Ignoring these systems could lead to misinterpretations of the fire's origin and cause, while immediate repairs might interfere with the investigation process. Monitoring for leaks alone does not address the broader necessity of assessing all aspects of the fuel gas systems. Therefore, careful examination and thorough documentation are essential for establishing a complete understanding of the fire scene.
