Which of the following is NOT a type of valve commonly associated with fire investigation?

Diverter valves are not typically associated with fire investigation in the context of identifying and analyzing fire scenarios. They are primarily used in plumbing systems to direct the flow of water or gas to different outlets, rather than being specifically linked to the control or regulation of fuel supply in fire scenarios.

On the other hand, the other mentioned types of valves—main burner control valves, manual reset valves, and individual burner valves—are directly involved in managing fuel flow and combustion processes, which are critical aspects of fire investigations. Main burner control valves regulate the fuel supply to the main burner, whereas individual burner valves control the flow of fuel to different burners separately. Manual reset valves are also important because they require action to reset after an incident, which can be crucial in understanding what occurred during a fire event.
