Considering that boiling temperature is very close, you have to be careful with pressure drop, that could give you a dangerous vapour phase.

I don't know how much the pressure inside is, but I think it would be dangerous in a large scale, to work with atmospheric pressure.

If some of the IPA evaporates for any random reason, you would have a pressure inside that is lower that the outside, that means that if the system it's not perfectly isolated, you will have air inside.

For explosive compounds, it's always better to work with higher pressure, because in the worst case, you would have a IPA loss instead of air inside.

Have a nice day and good luck

Hi Matteo,

Thank you very much for your inputs.

I will consider the pressure issue.
