Posted by Astro Well, first...where are you? What part of the country? |
Posted by MYSTERY-IS-IN-THE-AIR I live near LA. Just about an hour away |
Posted by MYSTERY-IS-IN-THE-AIR I wouldn't mind just going down these tunnels, but I don't want to die because of the lack of oxygen. There could be busy streets further down these tunnels which would fill them with carbon monoxide. What do you recommend me to do? |
Posted by Dominus Take a look at this, it might be able to help you a bit. http://dpw.lacount...ormdrain/index.cfm Also, I suggest taking a look at this: http://sleepycity....proach-to-draining Not all the information will be relevant, but it's an excellent introduction to draining and has some helpful information. Good luck! |
Posted by Sectovan So this may sound like a stupid question but I've never been draining before. How can you tell the difference between a drain and a sewer? Is it obvious? I've seen some nice tunnels around Milwaukee I've been meaning to check out but I haven't had the time and was wondering what they actually were. |
Posted by MYSTERY-IS-IN-THE-AIR I have some waterproof boots, a breathing mask, and a good flashlight, but I'm not sure if I should go all the way down these tunnels. Is there a way to get the drain tunnel lay out from a website, or maybe from the city? I wouldn't mind just going down these tunnels, but I don't want to die because of the lack of oxygen. There could be busy streets further down these tunnels which would fill them with carbon monoxide. What do you recommend me to do? |
Posted by Ptasteful_Pteranodon Don't want to spread misinformation, but I've read that a potentially useful technique for determining if oxygen is too low is by bringing matches. Supposedly, if you can't get a match to stay lit, that could indicate that O2 levels in the area are dangerously low, and you should leave immediately. I can see this as working in theory, but I would imagine that a flame could probably survive in lower-oxygen levels than a human could for very long, and that's not even accounting for the toxicity of potential asphyxiant gases like H2S or CO in tunnels. Can anyone with greater knowledge in the field shed some more light on the effectiveness (or lack thereof) of this technique? |
Posted by Nihil Novi Well, you can usually gauge how well known a tunnel is by the amount of graffiti. More graffiti=more people. More people=greater chance of human based danger. However, less graffiti and less human contact can mean more environmental dangers, ie deep water, dangerous animals, or hazardous gas. |
Posted by Aran Also be aware that when you are in a drain, you are under several feet of concrete, dirt, and asphalt. It's not uncommon for there to be no cell service inside tunnels and drains. If you slip or fall and hurt yourself or somehow get stuck, you're on your own. Unlike abandoned buildings and rooftops, you can't count on being able to call for help in a life threatening situation. |
