We keep a tube of calcium gluconate gel in the lab first aid kit; it's the recommended immediate treatment (following water wash). Never been used & (according to expiration date) needs to be replaced annually.
Sigma Aldrich MSDS:
FIRST AID MEASURES
Consult a physician. Show this safety data sheet to the doctor in attendance. Hydrofluoric (HF) acid burns require
immediate and specialized first aid and medical treatment. Symptoms may be delayed up to 24 hours depending on the
concentration of HF.After decontamination with water, further damage can occur due to penetration/absorption of the
fluoride ion. Treatment should be directed toward binding the fluoride ion as well as the effects of exposure. Skin
exposures can be treated with a 2.5% calcium gluconate gel repeated until burning ceases. More serious skin exposures
may require subcutaneous calcium gluconate except for digital areas unless the physician is experienced in this
technique, due to the potential for tissue injury from increased pressure. Absorption can readily occur through the
subungual areas and should be considered when undergoing decontamination. Prevention of absorption of the fluoride
ion in cases of ingestion can be obtained by giving milk, chewable calcium carbonate tablets or Milk of Magnesia to
conscious victims. Conditions such as hypocalcemia, hypomagnesemia and cardiac arrhythmias should be monitored for,
since they can occur after exposure. Move out of dangerous area.

Subject: [DCHAS-L] Question on trifluoracetic acid & emergencies
One of the labs on campus asked about having an HF emergency kit for trifluoracetic acid use.
I need the collective wisdom of his group - yes? no? references? (the SDS doesn't mention anything about this)
