Liquid air is the same as normal air. During its liquid stage it would be entirely enclosed in pipes. It can be safely expanded using the technology used in mine rescue suits like those from Draegerman.
You are confusing it with liquid oxygen which is just as dangerous in its gas form as it is when liquid. Air has some 70+ percent nitrogen in it, whether gas or liquid, and that prevents it from being any more corrosive or flammable than plain air.
