Sewage gases from toilets post shtf

[Geordie_Rob]

I've googled sewage gas & allegedly normal gases aren't dangerous, just smelly. It's when they get into higher concentrations (I'm assuming by rotting away in pipes rather than being treated as they are now) that it becomes dangerous. The sulphide gas (smells of rotten eggs) normally measured in parts per billion. If it gets to the concentration of more than 300 parts per million its usually fatal. If not, can give you all sorts of lovely things like pneumonia (taken from wiki).

If where you're bugging out to has a toilet connected to the mains sewerage, you're still gonna have the problem BP.

I know it's not a great subject, just I think it's something we're going to have to face upto post shtf if an event happens.
