       Fediverse mask geeks. I'm wearing a 3m 7502 half face respirator. I have a 6055 A2 filter, with a 5935 P3 filter clipped on top. I've generally been happy with it. But today, when using an angle grinder. I could smell the angle grinder, even tho I was wearing the mask.Is this a case of:A) badly fitted mask?B) wrong filterC) filter life exceeded.The P3 filter in the outside is grey, suggesting it is catching something. (It was previously more black).

       @quixoticgeek Is that a particulate mask? Or does it include organic gases? You may be smelling a gas generated by the heat of grinding and not any dust.

       @tomjennings read the original toot. It has a P3 filter for particles. And an A2 filter for organic solvents.

       @quixoticgeek D'oh, it was so obvious I clearly read it and did not register. Apologies.
