Posted by Regret What's the difference between "All Particulates" and "Multi-Contaminant"? |
Posted by SodoSyco I would like to share that it is good to keep filters in a bag so they don't absorb things in the air when not in use. I have heard this from both my welding instructor and the guys at the weld supply store. We use P100's. |
Posted by ZenCanadian One other note on this subject... to wear one of these properly means no facial hair... a beard, even trimmed up can allow enough of an opening to let the bad stuff in. |

Posted by SuchundFind Depends on the mask, and you can test it as you might know. |
Posted by Send4Help Technically ZenCanadian is correct. If any of you are Fire I or II certified you will know you cant get certified unless you are clean shaved. There have been many court rulings upholding this (ie: http://aerospace.c...s/FST481beards.pdf). |
Posted by SuchundFind Ok, I am just NBC certificated, I am also certificated to test NBC masks. As the armed forces most of the times are above any court rulings, I don't know any of them and really don't care about them. |
Posted by CatAndTie Is a short beard considered stubble or 5 o'clock or more like a trimmed beard? My stubble comes through quick, so does that mean I am leaving a gap big enough to affect my mask? |
Posted by Send4Help Simple answer... Maybe? The best thing to do is to try a simple breathing test... Take off the filters of the mask and cover the inlets of your mask with your palms (or plastic wrap, etc) to stop the intake of air. Without putting on more pressure then the straps would normally push against your face try to breath in. If you feel/hear air coming in around the mask/beard area then you should consider a shave, if not you are probably just fine. The actual standards would normally call for a clean shave, but again, we arent really dealing with something that is going to be affected by an extra 5 parts-per-trillion that can slide in under a mostly closed system. |
Posted by SuchundFind So where are again is the big difference between the soldier in the field and the urban explorer? |
Posted by SuchundFind Actually this is how the soldiers test there masks every time they get them ready. So where are again is the big difference between the soldier in the field and the urban explorer? |
Posted by Them I'm in an area of the country with a number of abandoned paper mills. I know those are pretty toxic, is that one of the places where a full face mask might actually be necessary? |
