I contend that flashover would potentially be a normal part of fire development, but is also extreme, at least in the … Read more

Myth of the Self-Vented Fire

When fire is showing from one or more windows or other opening on arrival, firefighters and fire officers often observe that the fire is “self-vented”.

Ventilation Tactics: Understanding and Application

Second only to the great solid stream versus fog debate, ventilation strategies seem to create the most discussion and disagreement among fire service practitioners.
