A reader reacts to an earlier Nozzlehead column about how fire science is challenging our tactics, arguing that recent research supports the department’s long-used tactic of employing semi-fog patterns in direct attack.

Changes to building construction and fuel loads have transformed most fires we go to from being fuel-controlled to being ventilation-controlled. Fire behavior researcher and fire chief Ed Hartin discusses the implications of this change, and the importance of door control and anti-ventilation in today’s fire environment.

Andy Speier provides several examples of incidents that firefighters may encounter while off-duty and key considerations for how to ensure a successful outcome.
