| [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] 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. 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. Store in a cool, dry, well-ventilated area away from incompatible substances. | |
| [Handling] Wash thoroughly after handling. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Do not ingest or inhale. | |
| [Ingestion] Harmful if swallowed. The toxicological properties of this substance have not been fully investigated. May cause central nervous system effects. | |
| [Inhalation] The toxicological properties of this substance have not been fully investigated. | |
| [Skin] Causes skin irritation. | |
| [Eyes] Causes eye irritation. | |
| [Hazards] Contact with metals may evolve flammable hydrogen gas. | |
