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. Do not induce vomiting.

SIGNS AND SYMPTOMS OF EXPOSURE
ALDRICH - 229814 www.sigma-aldrich.com Page 3
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. Material is extremely destructive to
tissue of the mucous membranes and upper respiratory tract,
eyes, and skin. 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. To the best of our knowledge,
the chemical, physical, and toxicological properties have not
been thoroughly investigated.
ROUTE OF EXPOSURE
Skin Contact: Causes burns.
Skin Absorption: Toxic if absorbed through skin.
Eye Contact: Causes burns.
Inhalation: Toxic if inhaled. Material is extremely destructive
to the tissue of the mucous membranes and upper respiratory
tract.
Ingestion: Toxic if swallowed.
TARGET ORGAN INFORMATION
Kidneys. Heart. Bones. Nerves. G.I. System. Teeth.
