any body know much about this stuff?

the other day i was at work cleaning a packaging machine, and i put my had under a part, and something very cold dripped on the back of my hand.

after asking the person who runs that particular machine, he told me it was liquid nitrogen. then he showed me where the off switch was for the sensor, WHICH WAS LIVE WHEN I HAD MY HAND UNDER IT.

so i have a question:

does storage temperature or quantity have any affect on the damage this stuff can cause?

 

I had some warts and moles "burned" off with the stuff.

I don't think quantity or quality has any effect, liquid nitrogen is liquid nitrogen
and is a specific temperature regardless of storage temp, really darn cold!

You'll have a nice blister, at the least.

It is usually (and opinions vary) about 350-400 degrees below zero. We use it where i work to shrink bearings and inserts for assembly. A couple of drops wont hurt, but stay away from any streams or direct contact. It will freeze a Dixie cup of water in about 20 seconds.

 

A little bit does not hurt on regular skin, so you'll be ok. I've played with it like a retard, and it never hurt me.

 

We use it on the pipeline when Hydro testing the pipe is full of water and we install fiberglass sleeves with lines running into it kind of like a pipeline coozie and turn the nitrogen on it freezes the water inside and you can then cut the line open and make repairs the "freeze plug" will hold everything in the line instead of having to drain up before doing the repair work.

 

I remember the guys in the periscope shop catching wharf rats and dipping them in a vat of liquid nitrogen. After a few seconds dip, they would throw them oven on the pier and they would shatter like a light bulb. Then they thawed out.
Kinda neat.

Dont get a drop in your eye, itll blind you. We pump N2 at work, its some cool stuff, but can be dangerous if your not careful. Ever heard of a nitrogen bomb??? (in a bottle of course...)

 

We use it to freeze brand horses. Only a few seconds of contact with the iron and in a week or so, you get a white hairs growing back in the shape of the brand. it just kills the cells that pigments the hair.
A few drops wont hurt you, might sting and maybe a blister, but like to other guys said, none in the eyes, no concentrated direct contact etc.

 

that sounds like fun! i wounder where i can get some of that.

 

Do yourself a favor and avoid getting hurt, maimed or killed.
Lock out, Tag out (with your own lock and keep the key on you) & isolate the machine before working on it. Next time it could be loosing a limb or worse, and we don't want that happening to anyone! Especially a fellow Cummins owner.

 

Same here hat. We used that stuff for fire suppresion on the C-5. Dude we would freeze frogs and stuff with it, they pick them up trow them and watch them shatter. Liquid oxygen does the same thing, just a little more dangerous. It was always fun except in the winter when it was cold outside and then having to deal with the cold nitro.
