Cocktail of liquid nitrogen - Girl has stomach removed

hope they don't ban nitrogen.

quite likely considering their level of scientific literacy.

What would we replace atmospheric nitrogen with? Partial pressures of O2 much above what we have are quite toxic, and fires become a real problem. How much would it cost to replace the atmosphere with a diving trimix?

The sun's got loads of Helium in it, let's go and get that. Added bonus of funny Joe Pasquale voices.

It really doesn't need more fecking legislation, a dose of common sense really should suffice.

They definitely should ban it, what difference does it make really. It shouldn't be being used anyway.

A Tesco approach to the elf in safety would be unsuitable here

[RealSquirrels]

argon would be the best bet for replacing nitrogen I think.

Can't remember the percentage, but argon is quite narcotic.

Not quite the same in terms of detail but just the same in terms of stupidity and the harmful outcome.

More liquid nitrogen idiocy

I think I'm with this guy from the comments:

In what way could this ever have gone 'right'?

Choking on chlorine gas is only mildly less preferable to drinking that stuff in the first place.

I wonder what the reaction they were supposedly getting is? My chemistry is terrible but nitrogen gas is pretty inert. I would have guessed that they were just being suffocated by the nitrogen displacing oxygen.

The article says "Officials say that when the liquid nitrogen came in contact with the water, the chemical substance reacted with the chlorine and formed a toxic cloud that left the young party goers gasping for breath"

I don't really understand that, from a chemistry p.o.v. Anyone?

Seems more likely that a cloud of cold, inert nitrogen would form on the surface of the pool and act as an asphyxiant.

[otolith]

It's total bks, there was no reaction, they asphyxiated in a layer of cold nitrogen.

Without doing any research is it not also quite likely the chlorine is less soluble in water at lower temps hence nitrogen cloud plus chlorine evolving out the water at the same time. All in all, not something I'd choose to inhale.

Probably. Newspapers are not famous for accuracy with things like this.

Oh yes, and there is so much Chlorine in a swimming pool (not aimed at previous posters, just sarcasm ).

Pour liquid Nitrogen into water and the Nitrogen 'boils', expands a lot as it becomes gaseous and people will suffocate invisibly (as stated above, in effect) - just because the party-goers are out of the 'cloud' doesn't mean they have any access to Oxygen ...

When good times go bad, eh?

[otolith]

Gas solubility generally decreases with temperature. Chlorine is usually added to swimming pools in the form of bleach. I think this was a similar accident to a spill of liquid nitrogen in a confined space or pit.

[rhinochopig]

It was probably the prescence of a video camera. In my extensive research there is a strong corrolation between near fatal accidents and the video cameras. They're just lucky someone didn't shout "watch this".

[hairykrishna]

I wonder why they were using LN2? Dry ice lumps would give basically the same effect and at least you'd get some warning that you're suffocating before passing out.

Now consider that you have already put more thought into it than the organisers...
