Section 3 - HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Toxic if swallowed. Contact with acids liberates very toxic gas.
Irritating to eyes and skin.Moisture sensitive.
Potential Health Effects
Eye:
Causes moderate eye irritation.
Skin:
Contact with skin causes irritation and possible burns, especially if the skin is wet or moist.
Ingestion:
May be fatal if swallowed. Poison by ingestion. May cause respiratory failure. May cause severe gastrointestinal tract irritation with nausea, vomiting and possible burns. May cause circulatory system failure.
Inhalation:
May cause irritation of the respiratory tract with burning pain in the nose and throat, coughing, wheezing, shortness of breath and pulmonary edema. The toxicological properties of this substance have not been fully investigated.
Chronic:
Chronic inhalation and ingestion may cause chronic fluoride poisoning (fluorosis) characterized by weight loss, weakness, anemia, brittle bones, and stiff joints. May cause kidney injury.
Chronic exposure may lead to liver and lung damage.

Section 4 - FIRST AID MEASURES
Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Inhalation:
Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:

Section 5 - FIRE FIGHTING MEASURES
General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Material will not burn. Wear appropriate protective clothing to prevent contact with skin and eyes. Wear a self-contained breathing apparatus (SCBA) to prevent contact with thermal decomposition products.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
