"First aid for a unique acid, HF: A sequel," Chemical Health & Safety, Eileen B. Segal, American Chemical Society, January/February 2000, pp. 18-23, has some advice down to 2%
62 FR 61928-61933, November 20, 1997 - revised 12/4/03, 12/14/11 has bits of information because the CPSC is proposing to require child resistant packaging for anything containing more than 0.5% of any elemental fluoride and they specifically mention rust removers and glass etching kits.
But I have nothing in my file about precautions at 0.1% HF. I would, however, generally agree that having the stuff on hand and using that product as a training opportunity would be a good thing.

I'm not a physician here, but here's my take:
Honeywell's guide does give cutoff concentrations to define "dilute."

Subject: [DCHAS-L] HF concentration and gluconate gel
I received a cold call for gluconate gel kits this morning that I sent on to departmental CHO's. Someone asked if they should have kits available for low concentrations of HF (<0.1%).
Does anybody have a HF "cutoff" where they don't require/recommend kits be immediately available in the laboratory?
