No Smoke, No Fire... Why The Foam?

Hello, I was looking at this pictures of an aircraft that crash landed today in an access road to the city of Viña del Mar, Chile.

http://www.emol.com/MundoGrafico/index.asp?G_ID=17983


There is no sign of smoke or fire, however this guys are spraying foam everywhere ( the left engine was totally covered with it ).

Were they preventing a possible fire due to a possible fuel leak ?

Is this the correct action to take ? or was the foam unnecessary in this case and they are only causing more damage to the engine ?

Rgds.

It is to prevent possible fire from leaked kerosene.

Did that crash happen near Rodelillo or on the Ruta 68 .. can't quite make it out ...

Thank you, that confirms my thought.

According to this article they were landing with tail wind, in a flight from Juan Fernandez with 1000 lobsters valued in 20000 USD.
The two occupants sustained minor injures only.

Sorry but is only in Spanish

Also additionally, in some areas, the foam is to prevent the fuel from being caught in the runoff since the foam makes the water and fuel/foam mixture immiscible.

Yes to prevent flash fire and to contain fuel leak for environmental purposes. Lucky the plane's cabin missed that pole!

First was this a turboprop or piston? Avgas, with a lower flashpoint, would be much more dangerious than jet A. Second why was the fire engine parked in the potentioal fuel spill??!! Like putting water on the roof when the fire is contained in the living room. Why were people without fire gear on allowed in the danger zone??!! You are correct in questioning why foam on the wing. If there is a fuel spill, the fuel is on the ground. Looks like they have good equipment but very poor training and or leadership

Good point! One could only hope this photo was well after the scene was secured and they moved in, but I sense you are correct that may be where they rolled up to during the initial response... and not a good idea. Scene safety fail if so.

Yeah that's a nice truck. Looks new. Glad it did not get cooked.

Although not captured from the actual beginning all it took was a spark and some kerosene

Or as it says in the comments, an engine fire. A spill of JetA is not that easy to start on fire due to its high flash point. However if leaking on a hot engine, it will catch on fie.

Ran out of fuel?

Totally agree. One of the problems of being a member of the Chilean Fire Department is, you got very good equipment, but little training ( for basic combat of "common fire" ), and no pay, is an entirely volunteer activity. Only the FD of Santiago have the training to cope with fires in our "skyscrapers" and other situations like a plane crash, or HAZMAT related.
In my job we were amazed a couple of times for the lack of basic training in HAZMAT they had, although I really appreciate the bravery of this people, but is totally true, they need better training and some basic understanding of the different types of emergencies they could face daily.

That wouldn't surprise me at all...

Well, this is a common problem here, the "paparazzis" and all the curious always find a way to the site, and once they're there, is very hard they leave the scene unless all the thing blows up.... very smart people

This part is irrelevant - 2/3 (little over) of America's fire fighters are volunteer - but they are trained and professional.
