| [Fire Fighting] Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam. | |
| [Fire Potential] Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. | |
| [Ingestion] Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. 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. | |
| [Skin] Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. | |
| [Eyes] Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. | |
| [Storage] Store in a tightly closed container. Keep under an argon blanket. Refrigerator (approx 4 C). | |
| [Handling] Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Container should be opened by a technically qualified person. Use only in a chemical fume hood. | |
| [Ingestion] Causes gastrointestinal tract burns. The toxicological properties of this substance have not been fully investigated. | |
| [Inhalation] May be fatal if inhaled. Causes chemical burns to the respiratory tract. | |
| [Skin] Causes skin burns. | |
| [Eyes] Causes eye burns. | |
| [Hazards] Contact with metals may evolve flammable hydrogen gas. | |
