|ATF Warns Emergency Response Personnel about Flame Jetting Phenomenon|
|March 6, 2013|
The ATF crew wanted to share this information and below video segments for distribution on The Secret List. They have been trying to get the word out to firefighters, fire investigators and code officials. It's a not-so-well known flame jetting phenomenon that they came upon while evaluating a suspects statement. Since they've begun to get the word out, it turns out that there have been numerous flame jetting injuries that were once thought to be isolated "freak" incidents. The 17 year old victim in this particular case was the daughter of a Baltimore County Firefighter (and good friend of Fallen Firefighter, Mark Falkenhan).
In separate tests, flame jetting was documented with burner flames in direct contact with the mouth of the container (piloted ignition) as well as with burner flames that were several inches from the mouth of the container at the time of ignition (non-piloted ignition). The flame jet was observed extending as far as 4 m (13 ft) horizontally.The flame jet propelled ignited liquid out of the gasoline container.The propelled liquid ignited cotton clothing on a mannequin located 1.3 m (4.3 ft) away and sustained burning after the momentary flame jet self-extinguished. The entire jetting event lasted less than one second, with no observable warning signs prior to the phenomenon.When jetting did occur, there was no evidence of thermal or pressure damage to the container.The length of the flame jet was dependent on several variables, including the total quantity of liquid, the mixture ratio and the percentage that the gasoline was "weathered."Flame jets as small as 6 inches were observed in subsequent testing. If the nozzle is in place when the flame travels into the container, the container has been documented to rupture and often injures the person holding the container.
