Introducing air into a ventilation-limited fire can result in:

Introducing air into a ventilation-limited fire can significantly enhance the fire's intensity and rate of growth, potentially leading to explosive fire growth. In a scenario where a fire is ventilation-limited, it means that there is insufficient oxygen available to support combustion at a rate that maximizes energy release.

When additional air is introduced into this environment, such as through openings created by ventilation efforts or breaks in the structure, the fire suddenly receives the oxygen it needs to accelerate combustion. This can result in rapid, nearly uncontrollable increases in heat and flame spread, culminating in explosive fire growth. This phenomenon is often referred to as flashover, where all combustible materials in the vicinity ignite almost simultaneously due to the intense heat and abundant oxygen.

Understanding this concept is crucial for firefighters, as it informs tactics related to ventilation, suppression, and overall fire management. Thus, introducing air into a ventilation-limited fire not only risks the safety of firefighters and occupants but also significantly exacerbates property damage.
