| First Aid Measures | Back to Contents | 【Ingestion】
Get medical aid. Wash mouth out with 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. | 【Eyes】
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid. |
| Handling and Storage | Back to Contents | 【Storage】
Keep away from sources of ignition. Do not store in direct sunlight. Store in a tightly closed container. Store in a dry area. Keep under a nitrogen blanket. Refrigerator (approx 4 C). | 【Handling】
Use spark-proof tools and explosion proof equipment. Avoid breathing dust, vapor, mist, or gas. Avoid contact with skin and eyes. |
| Hazards Identification | Back to Contents | 【Ingestion】
The toxicological properties of this substance have not been fully investigated. | 【Inhalation】
Causes respiratory tract irritation. The toxicological properties of this substance have not been fully investigated. | 【Skin】
Causes skin irritation. | 【Eyes】
Causes eye irritation. | 【Hazards】
Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. | 【EC Risk Phrase】
