TL;DR: There’s more to “masks” than one may think initially and, as the endless papers continue streaming out of academic journals and Google Scholar, contrary to popular belief, the pandemic that started in 2019 hasn’t ended?
CPCs can be used to measure very small particles. In the context of pandemic denialism, and unmitigated viral evolution, it has become increasingly important to wear good quality PPE, especially in the context of Long COVID.
In other words, the SARS-COV-2 COVID pandemic is becoming increasingly high stakes, sort of like that tiny, rookie unit conversion error on Mars. How do we know one error can substantially affect your fit factor? Well…
Due to the flood of low-quality PPE (cough surgical masks) that came out in 2020, people have increasingly sworn off taking any measures, (see also: survivorship bias), despite the fact people in NIOSH, MSHA, and the Bureau of Mines, have, since the Progressive Era, taken great pains to ensure masks work through qualitative fit testing, quantitative fit testing with lab equipment, and since 1987, portable quantitative fit testing with the PortaCount condensation particle counter.
(If those links weren’t enough to convince you that this is a Progressive Era issue, this one will.)
Makes you wonder why CPC fit testing isn’t everywhere, huh? Okay, I haven’t answered my question, future lawyers can answer that (if there even is a future…), but hey, at least antimaskers can’t deny PortaCount fit testing, unless they want to deny 100 years of occupational safety research. As an added bonus, with CPC, you won’t be the person who sticks their glasses under their full-face respirator.
TL;DR: Sticking glasses in your respirator = simple unit conversion error = you ending up on Mars, or something, idk
With that being said: Please keep /m/CPCSupport about CPCs and mask fit testing. There are other places to discuss COVID. Heck, you can create your own magazine, or post to the #covid hashtag on the Fediverse microblog.
