Some are concerned about Oxalic acid vaporisation producing a great deal
of toxic vapour, but the point of the treatment is that the oxalic acid
re-condenses within the hive very rapidly and coats everything in sight.
Leakage will occur, but it will be a minor amount and the fine crystals
will fall out of suspension fairly rapidly.
If due notice is taken of sealing up the hive and prevailing wind
direction, there should be very little exposure to the operative.
