Here's one persons story on their life without a stomach;

The Fukking idiot.
Have pity on this person? No way. It's just as bad as some fool swimming in shark infested water and has his legs chewed off. "oh poor me, i thought it'd be a good idea to get in and swim with sharks, they're nice animals really. But one of them didn't really like me, so he bit my legs off. Anyway, the authorities are going to shoot it now, because im a Fukking fool who couldn't just go for a swim in a pool and leave the sharks to swim around in their own territory"

...what? Did you actually read the article you quoted? In what way does your shark analogy have any relevance whatsoever?

It's also very likely that the owners will face criminal charges for some combination of criminal negligence, health and safety, and food safety violations.

This is the part I want to see.

I know that. It likely has been treated so not fit for human consumption. If not, then grand. But thanks for letting me know that ethanol is available from a laboratory supplier.

You misunderstand.... the 96 % which is available from Aldrich is drinkable. It is NOT treated chemically to prevent anyone from drinking it and you STILL have to pay duty on it when you buy it for your lab!

The 99 % is not. But not because it has been treated to prevent anyone form taking a sip.

That's just plain wrong. You can get 99.9999% pure ethanol from suppliers. There's no such thing as sigma and the rest of then putting a poison part into the alcohol to deter people drinking it. And yes, there are customs exemption forms you sign when ordering the stuff, so you pay zero duty on it. The reason you shouldn't drink the lab stuff is because it is produced by ethylene hydration, so there's potentially loads of petrochemical gunk in it (and also it started off life in coal / oil) ,compared to the food stuff, which is produced by fermenting sugars with yeast.

Funnily enough I was working in a lab where we flew through the stuff, and the boss did get a call from the guards to make sure he wasn't selling the stuff to the public.

You are a cruel bastard. The girl in that article sounds really brave, if I was in her position I probably would have just taken my chances and probably ended up with the cancer.

I reckon he didn't read the article and thought it was about the girl that drank the liquid nitrogen. Even at that it's still a harsh opinion of what happened. At 18 after a few drinks you'd assume what a bar serves is safe for consumption. The worst you'd be thinking of is maybe a really bad headache if you had no knowledge regarding the safety of consuming such a chemical.

Citing Material Safety Data Sheet:
"No specific information is available in our database regarding the other toxic effects of this material to humans. (...)
Ingestion is not a normal route of exposure for gases. Contact with cryogenic liquid can cause frostbite and cryogenic burns. (...)
No known significant effects or critical hazards. (...)
May cause rapid suffocation"
http://www.airgas.com/documents/pdf/001040.pdf

All of the above means liquid nitrogen is not toxic nor hazardous.

That's one of the strangest MSDS I've ever seen and I've used a lot of liq nitrogen.

As already mentioned in the thread liquid nitrogen expands 700 times when it evapourates i.e. 1 Litre of liquid will produce 700 Litres of gas. In a confined space this is extremely dangerous and hazardous as it rapidly decreases the levels of oxygen in the air and suffocation can easily occur and very rapidly.

Since it boils at -196C its also pretty cold in its liquid form which sounds like prety hazardous to me.

Liquid nitrogen is non toxic.

It is very hazardous.

A single drop on your hand is safe see my previous post about film boiling or look youtube. Prolonged contact is not good, ingestion is not good.

Don't ever get into a lift with a container of liquid nitrogen
if it spills you die
if the lift gets stuck you die.

Nitrogen is inert , most of what you breath is nitrogen gas
The hottest temperature liquid nitrogen can exist is -147 C and that's under a lot of pressure. Above that it's a supercritical fluid.

Just like Nitrogen, lead free solder is supposedly non toxic at room temperature. But at 200 degrees away from room temperature it like Nitrogen is most definitely hazardous.

I guess this might have been what I read in that textbook years back.

People do this in my workplace. :eek: Why they don't just send the container up in the lift and have someone meet it up there, I don't know.
