For post 1000, a gas mask question...
I picked up a couple gas masks at my local surplus store. I wasn't really sure what kind they were but they were so cheap I figured I couldn't go wrong. The only markings are "MSA" on the outside and "M3C2" on the inside. What type of filter does it use?

It's not a "gas mask" as far as being a military issued item - it's an industrial safety respirator, not that it's a bad thing. That is an MSA Ultra-Twin mask. Look for MSA "Comfo" filters - GME-P100 is the all-purpose SHTF filter that you want. GMC-P100 is a good filter also but doesn't protect against ammonia and probably a few other industrial chemicals.
MSA also sells the same general mask for LE riot control, so there are adapters for a 40mm threaded filter as well as a threaded cap to fit the off-side. I don't like that those masks come standard without a nosecup, and you definitely can get some fogging especially in humid environments. Nosecups are available but likely as expensive as what you paid for the whole mask. |

Quoted:
Brain do check the mask's sealing integrity by physical inspection and having an opened bottle of ammonia close to the sealing parts of the mask. Make sure you have the proper filter first. Some places specifically to inspect and clean to insure mask integrity are the seal between the cartridge holders and the mask itself, the o rings in the cartridge holders, and the exhalation valve which is critical on ANY mask (the cover just pops off). If it was me I'd probably check the voicemitter gasket/o ring as well - the voicemitter is that yellow thing you can see through the slots on the front of that round plastic piece, and it has an o ring between it and the plastic piece. |
