Neutralizing H2S-- Rendering Hydrogen Sulfide in the air into a non-toxic state Yes, as the title suggests I need to neutralize some H2S so that I can safely enter some confined spaces. I was hoping if I had another chemical that would neutralize the H2S then I could fill a fire extinguisher with it and use that to make the air non-toxic. I'd also like to reduce it into something that is safe to breathe, and prefferably non-corrosive and non-explosive. I know they don't make chemical indicators for it, either. The masks and containment suits I would need for this are more than 5 grand a pop and the meters are 2 grand a pop. I've also heard that by disturbing the H2S just from moving it in any way, can produce electrostatic charges and cause it to ignite itself. That might be a problem. If all else fails, I read an MSDS on the stuff and and am trying to figure out where I can get my hands on some Isoamyl Nitrite to use as an antidote. Alternatives to Isoamyl Nitrite are Sodium Nitrite, Pyridoxine, and Urea. The first two are to be taken through the inhalation route and the second two are to be taken intravenously as antidotes to H2S poisoning by inhalation. If anyone has any idea how the neutralization of H2S can be achived--even if you're just bouncing ideas--please let me know ASAP. Thanks!
