Where oxygen-free gases will kill you is if they're able to accumulate
in an enclosed space of some sort, and you then enter that space
expecting breathable air and pass out without warning.
The higher the volume of oxygen-free gas flow, the larger and/or
worse-enclosed the enclosed space that can become dangerous. (I won't
say it's impossible to have such a problem in open air with a breeze,
but you'd probably go deaf from the noise level of such a flow long
before you'd pass out from lack of oxygen.)
Mind, depending on how oxygenated your blood already is and how fast
you're currently using oxygen, an oxygen-free breath or two from right
near the source might make you dizzy enough to fall down. As long as
you're not hurt falling, and you land somewhere away from the immediate
source - neither a sure thing with a rocket test stand - you'll probably
be OK.

If you are sniffing the outlet you absolutely MUST use dry AIR as Paul says,
not dry NITROGEN so you don't suffocate yourself. I thought this was worth
some capital letters.
