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.

FIRST AID
MEASURES
General
advice
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)
Thanks
