What is fire dynamics mainly concerned with in the context of fire investigations?

Fire dynamics focuses primarily on the growth and behavior of fire. This encompasses understanding how fire ignites, spreads, and how its intensity changes over time. Analyzing these elements is crucial for fire investigators as it helps them determine the origin and cause of the fire. By examining the way fuel, oxygen, and heat interact, investigators can reconstruct the sequence of events that led to a fire, which is essential for accurately assessing incidents and identifying potential safety hazards.

While other factors such as social reactions to fire alarms, structural integrity during a fire, and investigation of fire-related injuries are relevant in the broader context of fire safety and response, they do not specifically fall under the purview of fire dynamics. Understanding fire dynamics enables investigators to link the physical effects of fire with patterns of damage and injury, contributing to a comprehensive investigation.
