SECTION 4. FIRST AID MEASURES

4.1 Description of first-aid measures
General advice
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.First
aiders need to protect themselves. Show this material safety data sheet to the doctor in
attendance.
If inhaled
After inhalation: fresh air. Call in physician.
In case of skin contact
First treatment with calcium gluconate paste.In case of skin contact: Take off immediately
all contaminated clothing. Rinse skin with water/ shower. Call a physician immediately.
In case of eye contact
After eye contact: rinse out with plenty of water. Immediately call in ophthalmologist.
Remove contact lenses.
If swallowed
If swallowed: give water to drink (two glasses at most). Seek medical advice immediately.
In exceptional cases only, if medical care is not available within one hour, induce vomiting
(only in persons who are wide awake and fully conscious), administer activated charcoal
(20 - 40 g in a 10% slurry) and consult a doctor as quickly as possible. Do not attempt to
neutralise.
