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


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.
