A report just released by San Fransisco fire officials on Friday said that flashover, not procedural errors, was cited in two San Fransisco firefighter LODDs last year.
Two San Francisco firefighters died in a house fire last year because a window blew out and turned a minor blaze into a 700-degree inferno that overcame the men within minutes, an eight-month Fire Department investigation has concluded.
A flare-up fueled by a broken window caused the deaths of two firefighters in a Diamond Heights house fire last year, and not procedural errors, San Francisco fire officials said Friday.
An internal safety investigation on the June 2, 2011, fire at 133 Berkeley Way indicates that firefighters Lt. Vincent A. Perez and Firefighter Paramedic Anthony M. Valerio were killed by extremely high temperatures of up to 700 degrees caused by a sudden flare up, known as a flashover.

Firefighters must continue to study and learn about hostile fire events
A sudden opening in the “box” (structure), whether triggered by the intense heat from the fire or created through fire-control (ventilation), lets in a rush of oxygen that can cause an intense fire event, a flashover. Flashover happens more often today, so figuring out what a fire is about to do before committing to an environment is not easy. Because firefighters have limited control over unexpected events, such as flashover, they must continue to study and learn the proactive warning signs of a hostile fire event to avoid being caught off guard.
