What model is it, I really want to know as it said more about the injured than the actual siren.

Reminds me of the video where an STL-10 blew up during testing.

Probably had a casting flaw. Decot had a large pit that he would lower each siren into for testing just for the this type of failure. Asc has a similar sound-proof enclosure

....As far as the explosion goes, would this be along the same lines as a clutch exploding in a manual transmission during high r.p.m's such as in a racing environment.

It was a Bullard siren.

Many years ago, speaking with one of J. N. Hedberg's workers, said they had a big siren, like the ones in my avatar, where the rotor/impeller maker had ran out of metal for the casting, had to melt more metal, then finished the casting. It also exploded during testing.

Hold on a minute...

So we obviously know that nowadays it is E.D. Bullard, but something struck me as a bit weird here. If you look closely, you can CLEARLY see that it says: "W.D. Bullard". Could this be an error when it was written, or does this mean that it originally stood for something else?

I had noticed this myself. I have a feeling it was a missed typo.

On most keyboards, the E key is right next to the W key. I'm 99% certain W.D. Bullard was a typo.

Woah mate the service drop exploded by the looks. Wires heated up and melted together perhaps?

That's what I thought too - the sparks came from the conduit a few feet below the siren, not the siren itself, although it wasn't doing much better!
