As long as it doesn't dissolve the bees I should think the hive would cope

With my 10 years experience, no.

Oxalic acid is stored in plastic bottles. No softening.

The OA itself isn't going to affect the plastic at all.

However, vaporising OA in a poly hive needs extreme care and forethought.
Because the hot vaporiser tool can do lots of damage to the plastic mouldings.
Its not impossible.
Just not quite the same as a wooden hive.

Having been raised on a market garden and used trays of burning sulphur inside vinery glasshouses, sprayed formaldehyde on the glass, poured formaldehyde onto trays of potassium permanganate to fumigate and encountered a multitude of other nasties I wonder just how hazardous vapourising oxalic while out in the fresh air really is?

So do you still do the above?

Or shifting bales of mouldy hay from one end of the barn to another? (he's dead now from farmer's lung)
I was thinking ,more of the proximity whilst playing a blowlamp over a piece of copper pipe

Speaking as someone who got sensitized to the isocyanates in polyurethane paints after just one night's spraying with the wrong grade of face mask .. and having suffered the consequences for the last 25 years ... You don't want to take the risk to find out !!

I learnt breath protection late, too. A really good mask is a trivial investment in the scale of things. I think of my hands. A bit like pargyle, but less seriously, one application of lacquer thinner and ten years of peeling. Can still see the thin spots a bit, decades later.
