Does anybody know of any academic literature around the medium-term (10 hours a day for 5 days) exposure to smoke machines?

@benjojo I only just found this, but my read on it is that "within safe levels, little to no effect".
but assuming safe levels is to assume a controlled environment and experienced stage technicians... which is unlikely to be the kinds of environment that you're experiencing smoke in.
another "bet you didn't know this about me" is that I did stage technician stuff for sound and lighting throughout the 1990s off and on... and I used to experience the worst hayfever symptoms immediately after leaving closed areas where we'd used lots of smoke machines (i.e. daytime rehearsals, and then pop outside to the only green space in the Summer). the older tech claimed that the smoke caused a reaction in the air passages like an irritant and that created a temporary far higher sensitivity to any other conditions.
my bet is more the anecdotal thing I experienced than this large academic doc.

@dee @benjojo the smoke in the entrance area was not very thick, it was more of a consistent haze to make the light show visible. In Halle H it was a light haze, likely because lasers needs less smoke. No idea what's defined as industry standard, but it was not _that_ much. It was longer than a night out though.

We were measuring air quality and was also asking the same question at our habitat.
Links from what someone gathered in the signal group we have.

Effects of theatrical smokes and fogs on respiratory health in the entertainment industry - PubMed
Mineral oil- and glycol-based fogs are associated with acute and chronic adverse effects on respiratory health among employees. Reducing exposure, through controls, substitution, and elimination where possible, is likely to reduce these effects.

Imo the smoke was quite thick on day 1, and the remaining days had less of it.

@Foxboron 2300ppm PM2.5 or something else?

@benjojo
C02, PM 2.5 said 1039 ug/m3

@benjojo Vape fluid tends to be a little different from fog fluid too (hazers tend to be 100% glycrerin, vapes mix that with some propylene glycol)
also i doubt CCC were using them but some hazers (primarily DF50s) are oil crackers
-
@benjojo (the DF50 produces a fantastically beautiful fine haze and also over a long time makes everything sticky in that way that anything kept in a kitchen becomes sticky)
