RE/
At 800 ppm, for instance, the symptoms will start in 45 minutes and you'll be dead after 3 hours. At 1600 pps it starts in 20 minutes and you're dead 40 minutes after that. At 6400 the pain starts in 2 minutes and you fall down go boom die in 10-15. This is why I've got CO monitors - plural - in my house. This stuff is NOTHING to fool around with. And, according to what I've heard, a nasty little add-on is that one's hemogloben has a greater affinity for CO than it does for O2. Net result is that once the stuff's bonded to enough hemogloben even if you get out to fresh air or somebody drags you out you're still going to die because the O2 from the fresh air can't get to the hemogloben. -- PeteCresswell |

One can detect the odor at about .03 ppm with the human nose. At about 10 ppm of hydrogen sulfide your nose loses it's sense of smell in as little as 3 minutes. So one might think it was just a little passing gust of the gas and it's now gone. But that may not be true. At about 30 ppm, the human nose loses it's sense of smell almost immediately. Yah just detect the odor, then it's gone. Because now yah can't smell anything. Guy in the previous post mentioned 800 ppm of CO as being hazardous if you're exposed to it long enough. With hydrogen sulfide, at 800 ppm, you're going nowhere. Not escaping. You hit the deck abruptly and promptly. Immediate unconciousness.

Didn't know that about H2S. Never used it. (Never will, now.) A *very* effective 'stink bomb' is a mild butyric acid solution. Smells like vomit (which is why it is know as "stench") and being a mild organic acid, bonds to just about anything. You can render clothes and packs un-wearable, and tents and buildings and vehicles un-usable, for very long periods, if not forever. A guerilla team in the bush that ran afoul of stench booby-trap would be in serious trouble. They could be smelled for a long ways and would upset the wildlife all around them and be incredibly miserable, IF they could even bear to wear their clothes and packs. I don't think they could. That stuff is upchuck city. I think they'd have to return to get re-supplied, and would be lucky to make it if they were very far into enemy territory. There's something very primal about scents. It's the only sense we have that is connected directly to the brain. AC |

Pumpers (oil lease caretakers) are issued electronic H2S detectors and those who occasionally work in those areas are issued a litmus paper sort of thingy that has a roll of the test paper inside and a small open window. If it changes color..bail. At the end of the shift, one simply pulls out a half inch of paper, exposing a new section. Some nasty shit. Ive had my snozz go dead in it, simply driving through a low spot on my way to my hunting shooting grounds. It of course is a by product of some oil wells, in this particular oil area there are various formations rich in H2S. Gunner " ..The world has gone crazy. Guess I'm showing my age... I think it dates from when we started looking at virtues as funny. It's embarrassing to speak of honor, integrity, bravery, patriotism, 'doing the right thing', charity, fairness. You have Seinfeld making cowardice an acceptable choice; our politicians changing positions of honor with every poll; we laugh at servicemen and patriotic fervor; we accept corruption in our police and bias in our judges; we kill our children, and wonder why they have no respect for Life. We deny children their childhood and innocence- and then we denigrate being a Man, as opposed to a 'person'. We *assume* that anyone with a weapon will use it against his fellowman- if only he has the chance. Nah; in our agitation to keep the State out of the church business, we've destroyed our value system and replaced it with *nothing*. Turns my stomach- " Chas , rec.knives |

Whether or not man is causing "global warming", man could correct it. Man could also probably fix the "nuclear winter" by vaporizing an appropriate volume of ocean with nukes. That's just brilliant.

Good disasters to ya, VLJ -- Take only pictures, leave only bullet holes ... I asked in an earlier post which disaster was under discussion here, because there are a few possibilities. 1. Global warming-which is happening now. 2. Nuclear winter which could happen if the wrong people press the button, or terrorists somehow- hopefully not for many years. 3. Fossil fuels used up. Oil production is expected to peak in about 10 years, which will bring prices up. No big deal, but what is next? In 250 years humans will use up all the fossil fuels that took 5 billion years to create. I don't remember god telling us we could do that? 4. Overpopulation and diminishing food supply- But hopefully this can be managed somehow. So is this all loony? Maybe, but it is all real and we hope that "THEY" whoever they are, will solve these problems. I am 43 so I think I will make it off the planet in time, but what about the little tikes of today and tomorrow? Overall, a sustainable way of life sounds better to me than trying to solve these problems with technology. Right on! The abuse and over-indulgence in technology is a big part of what's CAUSING our problems... More isn't going to do anything but make it worse. Does create jobs and profits for pension funds, though... Recycling is a perfect example of the folly of most technological 'solutions'. It actually does more harm to the environment than throwing things in a landfill and making new stuff. That's why recycled paper costs more than regular paper, even with subsidies. AC |

I remember the Internet in the Pacific Northwest being down for a half a day a while back because some farmer got careless with a backhoe. It is still dependent on microwave links and fiber-optic cables are more vulnerable than copper ones. A few teams of saboteurs could bring down the Internet right now, and never be caught.

It is associated with many types of oil...one clue there is that much of the original Texas classifications was "Light, Sweet Crude"...where there wasn't much of sulfur in the oil... So, smelling Sulfides around a petroleum plant (or a paper mill for that matter, where sulfites are used for bleaching), is not unusual. And as far as the oil fields go, there is an old John Wayne movie, "The Hellfighters"...a mildly fictionalized version of Red Adair's life...where Red, Boots and Coots were actual consultants on the set...they had one scene in Malaysia where the well out of control was a H2S well... ck -- country doc in louisiana (no fancy sayings right now) |
