SECTION 3 - HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Appearance: white crystals powder. Caution! May cause respiratory and digestive tract irritation. Causes severe eye and skin irritation.
Target Organs: No data found.
POTENTIAL HEALTH EFFECTS
Eye: Causes severe eye irritation.
Skin: Causes severe skin irritation.
Ingestion: Ingestion of large amounts of fluoride may include salivation, nausea, vomiting, abdominal pain, fever, labored breathing. Exposure to fluoride compounds can result in systemic toxic effects on the heart, liver, and kidneys. It may also deplete calcium levels in the body leading to hypocalcemia and death. Fluoride can reduce calcium levels leading to fatal hypocalcemia.
Inhalation: May cause respiratory tract irritation.
Chronic: No information found.

SECTION 4 - FIRST AID MEASURES
Eyes: 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. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
Ingestion: 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: Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Notes to Physician: Treat symptomatically and supportively.

SECTION 5 - FIRE FIGHTING MEASURES
