Which one of the following is a model used for assessing fire growth dynamics?

Egress analysis is a method that focuses on how individuals exit a space during a fire emergency and can indirectly provide insight into fire growth dynamics. By understanding the flow of people in relation to the spread of fire, investigators can gather valuable information on how quickly a fire may grow and spread within a given environment. This helps in assessing fire behavior and the potential for rapid escalation of a fire incident.

The other options, while useful in their respective contexts, do not specifically address the dynamics of fire growth. Thermal energy loss pertains to how heat escapes from a fire and can be a factor in understanding fire behavior, but it does not encapsulate the broader dynamics of fire growth. Carbon footprint analysis focuses on environmental impacts rather than fire dynamics, and psychological impact analysis examines human responses and behaviors during a fire but does not assess fire growth itself.
