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.
If inhaled
If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician.
In case of skin contact
Wash off with soap and plenty of water. Consult a physician.
In case of eye contact
Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.
If swallowed
Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.

Exposure controls / personal protection

Exposure controls
Appropriate engineering controls
Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at
the end of workday.
Personal protective equipment
Eye/face protection
Safety glasses with side-shields conforming to EN166 Use equipment for eye protection tested and
approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin protection
Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique (without
touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves
after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The
selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard
EN 374 derived from it.
Body Protection
impervious clothing, The type of protective equipment must be selected according to the
concentration and amount of the dangerous substance at the specific workplace.
Respiratory protection
For nuisance exposures use type P95 (US) or type P1 (EU EN 143) particle respirator. For higher
level protection use type OV/AG/P99 (US) or type ABEK-P2 (EU EN 143) respirator cartridges. Use
respirators and components tested and approved under appropriate government standards such as NIOSH
(US) or CEN (EU).
