Turner Valley-Sour Gas!

[fishinhogdaddy]

Just heard that a sour gas line ruptured in or around Turner Valley. People around there keep as safe as you can!

H2S is nasty stuff. At first it smells like rotten eggs, your second breath you will smell nothing at all, and your third breath will be your last. Scary. Be careful down there!!

Actually if you can smell it you are okay <100 ppm. At concentrations above that is when you begin to lose the sense of smell.

 

Very scary stuff indeed.

Sorry to correct you muffin but one of my back grounds is oilfield safety. 8 ppm is ohs standards is 8 hour exposure limit, at 50 ppm you lose senses ie. Smell, taste , and motor functions start to limit. At 100 to 150 if you are unable to have breathing aid scba etc available death or severe brain damage is likely. Im not trying to be a know it all person just rather educate people from my experience as i have witnessed h2s poisoning and i tell you its frieghtning having to save one who thought it was ok to breath in 20 ppm for 10 mins while he fixed his scba pack. But you are right be scared of h2s by the time you realize it its to late.

Oh good lord no, far from ok. <100 ppm will still cause you some serious eye, nose, throat and lung damage and can be fatal if exposed long enough. If I could smell H2S after a ruptured pipeline I wouldn't be hanging around there too long.

Sorry mistake on my part 100-150 ppm was supposed to be 150 to 1000 ppm 1000 being instant death. This is why you should not watch tv and type ha ha. Distracted typing could be a new one

[Muffin]

Oh right sorry. I knew my H2S tickets were coming due, this serves as a great reminder. I always go back through and read it when I am going back to the field which sadly hasn't been for awhile.

 

Thanks for the information drlevi and thanks for putting the correct info out there.

[drlevi]

Dxh you got that right get outta there up wind preferably if you know where leak is

[drlevi]

No problem muffin like i said i meant nothing by it, thats what this forum is great for so many people with such a diverse knowledge base. Now if i could just catch more fish id be a happy man

[Muffin]

Haha well when the waters go down drlevi we will get out.

Just a bit of a correction to this point...1000ppm does not mean instant death. You will lose consciousness immediately, in fact this will happen at 700ppm. Your body will shut down and you'll have to be rescued and revived within 4 to 6 minutes. Just a little info, the word was that the concentration of H2S in the pipeline was 1%...1% = 10,000ppm.
