Everything burns in Oxygen

Helium?
Neon?
Argon?
Only asking like.

Just did a quick search on what elements oxygen reacts with, but it turns out the question should be what doesn't it react with.

Hell of a BBQ if you can find the bits...

I found a picture of the horse after it was boiled.

Not a pretty sight.

At 95% it reacts with everything.

Especially at 22psi.

I would assume that the woman was outside the chamber operating the controls, rather than in there with horsey.

Probably got totalled by the door, which is the weakest part.

I think Zeity's comment above is most probably the cause!!!!

Must have been a bit of a loud bang if they heard it 30 miles away.

The Apollo one you mention seems to be have been more of a hiss, probably because the pressure vessel was a lot weaker than the horse box. But what's more of interest is that it was a fire that went on for some 17 seconds before boom time, rather than immediate explosion. The fire created the boom.

Only 17 seconds after the first indication by crew of any fire, the transmission ended abruptly at 6:31:21 with a cry of pain and then a hiss as the cabin ruptured after rapidly expanding gases from the fire over-pressurized the CM to 29 psi (200 kPa) and burst the cabin interior

No. I think he kicked the wall of the metal chamber with his steel shoes causing a spark but also driving a nail into the nerve in his hoof making him bite down in surprise. What he forgot was that he had metal fillings in his upper and lower frontal hook teeth. This resulted in sparking.... and also some smoke which reminded him we was gasping so he sat down and got out a fag and his zippo lighter. Put the fag in his mouth and light up taking a long slow wonderful drag. Upon exhaling he started coughing hard, so hard in fact he let out an involuntary fart which ignighted from his ciggy and blew the bleedin doors orf.... simple if you think about it really...

A slightly simpler explanation is that either there was combustible material in the oxygen rich air (e.g. hay particles) , or the horse burnt a horrible death (hair caught fire) that caused a secondary explosion that blew the chamber apart.

So you think the horse's steel shoes ignited and exploded?

Why are you guys trying to guess what it reacted with?? It's in the story. Pretty bloody dumb to put a metal shod horse in a steel container.. someone is going down for this...

She was Zeity.

Apparently the horse got spooked while inside and kicked out, horse shoes and metal sides did the rest.

They hadn't sedated the horse because it had been in the chamber before without incident.

I can see some changes to procedures coming.

Rhonda Stroup, a Marion sheriff detective, said the horse kicked off a protective shield inside of the oxygen-filled chamber, and as the steel shoe as struck the side of chamber, it caused a spark and ignited instantly

Probably shouldn't laugh, but I did when I got to the bit where it says "Acupuncture has become more widely accepted as an alternative therapy for horses."

Bloody good job too by the sounds of things...

[TimberWolf]

22 psi, 95% O2?

Stone me, Apollo 1 went up with 5psi & 100% O2.

Just did a quick search on what elements oxygen reacts with, but it turns out the question should be what doesn't it react with.

[TimberWolf]

Presumably the problem was worse than a normal gas explosion in this case because she was in a [strong] sealed container. Not a happy place to be.

[TimberWolf]

Presumably whatever the oxygen reacted with was in aerosol form, maybe quite a bit of hay dust or something. While the horse's hair and hooves would burn energetically in oxygen, to the detriment of the horses future well-being, I can't see it blowing the roof off.

I'm often surprised at how well people survive gas explosions though, not in this case; a house can be blown apart but people escape with singed hair and a surprised look.
