is it bad for you to be in an atmosphere with a higher than usual concentration of nitrogen?
I ask because we make large air conditioning units at work and they use nitrogen to purge the pipes whilst brazing and it's just venting into the shop..
also they use nitrogen to pressure test the units up to 300psi and they sometimes take 2-3 bottles of gas.. also vented into the shop..
