Manufacturers of vaporizers claim, of course, that vaporizers are safe
to operate. For (I assume) an independent opinion, Gumpp, et al. (2003),
in Germany, found that “By appropriate use there is no risk to the
health of the apiarist.” Their feeling was that the OA vapor quickly
recondenses into an aerosol of tiny crystals, which are less dangerous
than a vapor. They suggest wearing safety goggles, acid proof gloves,
and a disposable cloth dust/mist mask equivalent to NIOSH N95 (“N95”
will be stamped on the front—they cost anywhere from $12-$36 from
Conney.com).
