| [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. Extinguishing media: Use agent most appropriate to extinguish fire. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam. | |
| [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. Wash clothing before reuse. | |
| [Eyes] Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. | |
| [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. Refrigerator (approx 4 C). | |
| [Handling] Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. | |
| [Ingestion] May cause gastrointestinal irritation with nausea, vomiting and diarrhea. The toxicological properties of this substance have not been fully investigated. | |
| [Inhalation] May cause respiratory tract irritation. The toxicological properties of this substance have not been fully investigated. | |
| [Skin] May cause skin irritation. The toxicological properties of this material have not been fully investigated. | |
| [Eyes] May cause eye irritation. The toxicological properties of this material have not been fully investigated. | |
| [Hazards] During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. May explode when heated. | |
