I went through all of NYU Med School, Mass General, Harvard Med School, and a few workplace-safety equipment companies. No one wanted to give any impression that there was any safe way for a beekeeper to vaporize Oxalic. All said "find another way to kill mites".
I agree, just read the Materials Safety Data Sheets. And, in my opinion, EPA is lax in hand-waving at wearing a mask, which I find beekeepers interpreting that to mean that any disposable, particle filtering mask will suffice. OSHA seems to be missing from this whole issue. It's why I do not favor DIY applications.
