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?
