New nozzle designed to suppress flashover

This morning, Firegeezer.com has an exclusive article describing a new nozzle for firefighting that has been designed by Franck Gaviot-Blanc, a fire research scientist in France who specializes in advanced research into fire behavior and extinguishment methodology.

Optimal nozzle for firefighting

 

 … (it) is designed to suppress “flashover” conditions in a fire building and protect the firefighters inside from the deadly effects of the flashover.  This is done by creating an engineered fog pattern designed to suppress and cool the fire gasses that are waiting for ignition and flashover.

An interview with the inventor and complete description of the nozzle can be found HERE.

The Wheeling Fire Department received a call reporting a dryer fire this morning at 226 S. Fletcher Drive in their town. First arriving units reported light smoke showing. When they surveyed the house they noted active fire inside. Battalion 24 upgraded the alarm to a Code 4 which requested mutual aid from Buffalo Grove (Tower 25), Arlington Heights (Engine 4) and Long Grove (Ambulance 55). As the first engine company stretched a line and prepared to make entry into the 50×25 ranch house, the fire flashed. Crews were able to extinguish the bulk of the fire within minutes and then hit hot spots and performed overhaul. There were no injuries.

In the five to seven minutes that passed before crews arrived, the heat caused most of the house to “auto-ignite,” Battalion Chief Dave Palmeri said. Firefighters had the blaze under control within 10 minutes.
