| [Fire Fighting] Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion. To extinguish fire, use water, dry chemical, chemical foam, or alcohol-resistant foam. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam. | |
| [Ingestion] Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water. | |
| [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. Wash clothing before reuse. | |
| [Eyes] Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid. | |
| [Storage] Keep container closed when not in use. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. | |
| [Handling] Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in a well ventilated area. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. | |
| [Inhalation] Causes respiratory tract irritation. Can produce delayed pulmonary edema. | |
| [Skin] Causes skin irritation. | |
| [Eyes] Causes eye irritation. May cause chemical conjunctivitis. | |
| [Ingestion] May cause gastrointestinal irritation with nausea, vomiting and diarrhea. | |
