What is the technical understanding of how fires ignite, grow, and spread called?

The term that describes the technical understanding of how fires ignite, grow, and spread is known as Fire Dynamics. This field covers the principles of combustion, the behavior of fire in different environments, and how various materials affect the spread and intensity of a fire. Understanding fire dynamics allows fire safety professionals to predict fire development, implement effective firefighting strategies, and enhance overall safety measures.

While Fire Behavior is closely related, it typically focuses more on the observable actions of fire rather than a comprehensive study of the science behind it. Fire Safety encompasses a broader range of practices and measures designed to prevent fire incidents and protect lives, not specifically the technical processes involved in fire development. Fire Prevention is a proactive approach aimed at eliminating the conditions under which fire could start, but it does not delve into the underlying mechanics of fire behavior and growth.
