| | | | Well, I'm not the biggest drainer, but I know that methane buildup is a pretty big danger. Actually, there are many dangers to deal with, such as slipping and falling, bacteria in the water, and becoming trapped.
What you say sounds like methane. And a gas mask won't do you any good against it. You say it seems like you can't breathe. It might be that there is bad air circulation down there and this methane is building up, and if that's the case then you should find yourself a different drain. If you can see clouds of haze with distinct edges in the beam of your light, then you definitely have methane. This can suffocate you and is extremely flammable. This bad air, that contains too little oxygen, is dangerous because it can cause you to pass out.
Your gas mask won't help you with bad air, it can only filter impurities out. And that WWII gas mask probably isn't the best thing for exploring. You should get yourself a respirator that is designed to filter out mold and asbestos and other particulates in the air.
If you want to get into draining, I recommend you read http://www.infiltr...ions-approach.html which contains everything you want to know about the subject.
Close to the bottom is a whole section on gases and bad air.

| | | | Probably easier to list the safe things about going into drainage tunnels... unlikely to be strike by a falling satellite. /s
Seriously though if you don't think you can breathe that well it's probably from lack of oxygen... and a gas mask isn't going to help you.

|  | | | Occasionally, wildlife can be a concern. Turtles, raccoons, even catfish (which supposedly are armed with poisonous barbs).

| | | | It could certainly flare up...but in terms of filling the tunnel, there would have to be a lot of gas and I'm not sure you could breathe with that much...Plus doesn't it float at the top of the pipe/drain?
To fail in what you've yet to achieve is more the spirit of exploration than to make no attempt at all.

| | | | In an environment with 100% methane, it won't burn at all. Methane is a fuel. For kaboom you need the proper mix of fuel and air, then an ignition source. The big movie blasts are usually small explosive charges which blow a pool of gasoline into the air, atomizing it.
Oh, and if you do see a catfish, the spine is in it's dorsal (on the back) fin. They can be super nasty.

Ah, so that's where it is. I was in a drain this week crawling around in a roughly 2-foot pipe, with an inch of water in the bottom. There were a few small catfish flopping around in there (which I had to carefully crawl over), and one of them looked like he wanted to kick my ass xD
As far as gas buildups are concerned, I think you don't have to worry as much in storm drains, as opposed to sanitary sewers (never been in one, luckily). There are a few good signs to look for which should put your mind at ease - running water, I think, carries oxygen with it. Movement, as opposed to stagnation, should ventilate a drain. If the water is clear, that's a good sign too, as it's not full of rotting biomass. Of course, small holes, grates, gutters, and diverging pipes are good for air flow. It's always nice to take a break next to an opening to get some fresh air and light from outside - enjoy fresh air when you can in order to fight off that suffocating feeling.

I usually check for drops by taking a broom handle / stick with me to check depth and whatnot as I go, sweeping it back and forth in front of me like a stereotypical old-timey blind dude. It also provides you with something to rest your weight on when you're crouching down.

Stay in tunnels with airflow. Air has to come from somewhere, so either a cryogenic nitrogen truck spilled upstream to supply it, or there's wind coming through from the surface.
Bring more lights. You can navigate most drains in the dark, but it sucks.
Check the weather, know the drainage basin.
Don't hit your head, don't gouge your hands, feet, or legs, don't stick your fingers in cracks looking for spiders, and watch for snakes. If your heart rate starts to rise, the wind in the tunnel dies, or you feel faint/drunk/fuzzy, leave. If you hear rushing, roaring, or rumbling, get up out of where water will probably be flowing soon.

| | | | Easily the most understated danger of draining is dihydrogen monoxide.
Dihydrogen monoxide is a chemical that often accumulates in drains in both residential and commercial areas, and it can exist as either a gas or a liquid, occasionally in certain drains (mostly up north) as a solid. Dihydrogen monoxide is a natural byproduct of life and seeps into the sewers via the ground and osmosis and stuff.
To the rookie drainer, dihydrogen monoxide is a severe threat, highly caustic, suffocating and any contact with clothing will result in the clothing becoming saturated with the chemical and making a bad situation worse, creating massive rashes over large areas of the body and in short order it will make your wiener shrivel up and fall off. However, over time, the body creates a resistance to dihydrogen monoxide, and the vetern drainers among us lose any fear of dihydrogen monoxide after our first few encounters with a big, scary pool of the stuff.
