In which cases can nitrogen be dangerous ?

In which cases can nitrogen be dangerous ?
When it is in liquid state and when it is compressed.

How long is a bit of string?

You ask a very open ended question!!

Nitrogen in itself is harmless, we are surrounded by it.
We breath it in at 80% of the total make up of air.

It only becomes a problem when you miss use it when it is under pressure. Pressure kills.

Nitrogen is very safe, but do not leave any in your system after pressure testing because it is a non-condensible.

Sorry Taz.
I meant nitrogen in cylinder for refrigeration work purposes.
I would like to know how safe are the kits sold.
I write about electronics and refrigeration service and I am very worried about safety.

It can also be dangerous if it displaces the normal room air.
For example a Liquid Nitrogen freezing tunnel may require a O2 measuring device in case spillover into the room lowers the available oxygen.

Thanks for mentioning asphyxiation risk.

I found an nitrogen accident report, but I can not post links yet because I am a new member:

Just store it in a safe place and have it secured.

I was told by someone that if the cylinder falls and the neck snaps it could kill someone.

I don't know how likely this scenario is, but better be safe than sorry.

As far as I know the standard pressure in a standard
88 cuft cylinder is @ approximately 2214 PSIG, if the end were broken of from a fall, say off 2 story roof, then there is a good possibility that the nitro cylinder could turn into a rocket and end up being a short lived and very deadly health hazard.

Personally I never stand up my nitrogen in the field, unless I can tie it up to something sturdy, but I'm lazy so I just lay it down for safety.

I don't suppose you could be a tad more accurate with your approximation Enthalpy?
