hey MIke
I too work in a sour gas plant , the sour comes from H2s mostly and co2, the h2s can kill you in 1 breath if the concentration is high enough, the co2 is an inert gas and it will kill you to because of o2 defficiencies, if you get some you will start acting wierd and going crazy on your buddies and let the wife re-model the kitchen while he posts on the TDR... ... ... man sounds like dangerous stuff... ..... glad I didnt get any :{ Kevin
