Strange sparks at a car fire??????

[FireDiver111]

During a routine car fire last night, I noticed something and have no clue what it was. Something in the area of the airbags reacted like a 4th of July sparkler when hit with water.

The car was pretty much gone when we got on scene........and when the stream passed by both the driver and passenger air bag area.......BIG BRIGHT SPARKS!!!

Can anyone tell me what I was seeing?

Can you be more specific? Make and model of car and the year.

Many new vehicles have parts containing magnisium. I'm not sure if this is accurate or not, but I have heard that water will not extinguish a magnisium fire. I do know that some flares are made from magnisium and this may have caused the sparking you described.

Had to be something made of megnesium. I guess we don't tell recruits what it was like to see a fire in a VW with a nagnesium engine block years ago. They are still on the road; I drive one, and I also put out a few...........

The car was toast when we got there but I did here an police officer say it was a new Chrysler.

You can bet it was magnesium (or maybe titanium or some other exotic metal that burns). We deal with magnesium fire frequently at the local foundry and occasionally get the chance to train with some to show new members the result when you apply water to it. What I am told is happening when you do this is that the fire burns so hot that it breaks down the water into hydrogen and oxygen. When the hydrogen burns in the oxygen rich atmosphere, you get BIG sparking action.

I've also seen the same thing in the steering column of at least one chrysler product. Sure looks like magnesium to me. Plenty of water, it goes out.

Put my vote for Magnesium. Put out a few myself, also.

Another vote for magnesium...and I have had a few of these fires (including a 1973 VW beetle...now that was fun!)

Sounds like Magnesium

What the hell are you guys talking about it's magnesium. As the above statements say it's mag. be careful water can intensifie this type of fire. A couple towns over they had a vw burning in a carport the port wasn't invovled when they started but sure was when they were done.

[Halligan84]

The amount in the steering column is obviously very small. A decent flow from an 1 3/4 and its all gone in a few minutes. As far as V dubs.. Need water there too. Stuff like Metl X is great if you have a pile of shavings, but how do you layer it on a vertical surface of a vw engine block? The most stubborn one I ever saw required taking a hydrant, jacking the car and removing a rear wheel to get access and flood it until it stopped.

It is Magnesium, also there is a support that runs across the length of the dash in certain vehicles that is Magnesium also.

I used to work as a security/fire officer for one of the "Big 3". Magnesium is being used more often in cars now because it is a light metal. With the push for cars to be more fuel efficient the auto companies are trying to lighten the load.

Mag. is a popular metal of choice for the right-hand-drive retro kits to make the cars conform to European standards.

Because magnesium was being used in our plant, we had to train putting it out. The only thing that does the job quickly is a Class D extinguisher.

Saw the same thing in an "accident with fire" last year. I was behind the nozzleman, and when he hit the area of the steering column...whooeee, 4th of July.

It's definitely magnesium.
