V        HEALTH HAZARD INFORMATION



Toxicity Data: No Data



Effects of Overexposure: Inorganic fluorides are generally considered to be respiratory irritants. Inhalation will cause irritation of

mucous membranes and the general respiratory tract. Nosebleeds and sinus trouble may develop from chronic exposure. A mild to

moderate irritant of the skin and eyes. Ingestion of fluorides may cause nausea, vomiting, diarrhea and cramp-like pains. Long term

chronic exposure may cause development of fluorosis.



Medical Conditions Possibly Aggravated by Overexposure: Asthma and pre-existing lung diseases are generally aggravated by

exposure.



EMERGENCY AND FIRST AID PROCEDURES:



EYES: In case of contact, immediately flush eyes with water for at least 15 minutes.

SKIN: Remove contaminated clothing, brush material off skin, flush with running water, wash carefully with soap and water.

INHALATION/INGESTION: Remove from area of exposure. Seek immediate medical attention. Induce vomiting.
