| First Aid Measures | Back to Contents | 【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】
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. | 【Skin】
Get medical aid immediately. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. | 【Eyes】
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. |
| Handling and Storage | Back to Contents | 【Storage】
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. | 【Handling】
Wash thoroughly after handling. Use only in a well ventilated area. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation. |
| Hazards Identification | Back to Contents | 【Inhalation】
May cause severe irritation of the respiratory tract with possible burns. | 【Skin】
Causes skin irritation and possible severe skin irritation especially if the skin is wet or moist. | 【Eyes】
Causes eye irritation and possible burns. | 【Ingestion】
May cause severe gastrointestinal tract irritation with nausea, vomiting and possible burns. 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. Acute oral toxicity tests have shown lethality with central nervous system signs in mice. | 【Hazards】
When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards. | 【EC Risk Phrase】
