AFTER INHALATION
If inhaled, remove to fresh air. If not breathing give
artificial respiration. If breathing is difficult, give oxygen.
AFTER SKIN CONTACT
In case of skin contact, flush with copious amounts of water for
at least 15 minutes. Remove contaminated clothing and shoes.
Call a physician.
AFTER EYE CONTACT
In case of contact with eyes, flush with copious amounts of
water for at least 15 minutes. Assure adequate flushing by
separating the eyelids with fingers. Call a physician.
AFTER INGESTION
If swallowed, wash out mouth with water provided person is
conscious. Call a physician immediately.

11 - Toxicological Information
SIGNS AND SYMPTOMS OF EXPOSURE
Inhalation may result in spasm, inflammation and edema of the
larynxand bronchi, chemical pneumonitis, and pulmonary edema.
Symptoms of exposure may include burning sensation, coughing,
wheezing, laryngitis, shortness of breath, headache, nausea, and
vomiting. Material is extremely destructive to tissue of the
mucous membranes and upper respiratory tract, eyes, and skin.
Symptoms of fluoride overexposure may include salivation,
nausea, vomiting, abdominal pain, fever, and labored breathing.
Fluoride ion can reduce serum calcium levels possibly causing
fatal hypocalcemia. Prolonged exposure to fluoride dusts,
vapors, or mists results in perforation of the nasal septum.
Chronic effects include excessive calcification of the bones,
ligaments, and tendons. Symptoms may be delayed up to 24 hours
depending upon the fluoride ion concentration. 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. To the best
of our knowledge, the chemical, physical, and toxicological
properties have not been thoroughly investigated.
ROUTE OF EXPOSURE
Skin Contact: Causes burns.
FLUKA - 86872 www.sigma-aldrich.com Page 3
Skin Absorption: May be harmful if absorbed through the skin.
Eye Contact: Causes burns.
Inhalation: Material is extremely destructive to the tissue of
the mucous membranes and upper respiratory tract. May be harmful
if inhaled.
Ingestion: May be harmful if swallowed.
