Am I the only one that looks at gas masks and goes "What's the point?"
If it displaces oxygen I'm screwed
If a chem plant accident/train derails I'm screwed unless the industrial chemical is very common
If the Chicoms slime us I'm screwed. Not only can I not tell if an agent is present, I don't have the facilities or training to decon after I leave the area.
The one thing it's good for is particulate matter.I doubt I'll run into much CS and if I'm nuked I'll have much bigger problems than breathing in some alpha/beta particles, but it should be good for ash from volcanoes or forest fires. At least you can get a P100 respirator from 3M relatively cheaply. I already have a couple of those in the garage.
That's my take on it. Anyone have any other thoughts? Is a P100 full face respirator good enough or should I break down and buy one of those new M50 masks?

In recent years there's been a number of moments in my life where a mask has been of use:
A flu, volcano ash, bushfire smoke, and more recently ebola.
You mention nuclear explosion, and sure, you get nuked while sipping coffee in ground 0 and you're toast, but for a much larger of people such an explosion will give them some time, in some cases and depending exaclty where you are and where wind blows it may be just a matter of getting away from the fallout. Nuclear powerplant disasters also involve some time to evacuate or put a mask on.
Its not something people should rush into but I at least see it as vital enough that you should study your own situation, research whats available and prepare for it within your means.
