Guidance on Safe Use
Administrative data
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.
If inhaled
If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a
physician.
In case of skin contact
Take off contaminated clothing and shoes immediately. Wash off with soap and plenty of water. Consult
a physician.First treatment with calcium gluconate paste.
In case of eye contact
Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.
If swallowed
Do NOT induce vomiting. Never give anything by mouth to an unconscious person. Rinse mouth with
water. Consult a physician.
