| 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. | 【Skin】
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. |
| Handling and Storage | Back to Contents | 【Storage】
Keep away from sources of ignition. Store in a cool, dry place. Store in a tightly closed container. Flammables-area. | 【Handling】
Use spark-proof tools and explosion proof equipment. Avoid breathing dust, vapor, mist, or gas. Avoid contact with skin and eyes. Use only in a chemical fume hood. |
| Hazards Identification | Back to Contents | 【Inhalation】
Harmful if inhaled. May cause respiratory tract irritation. | 【Skin】
May cause skin irritation. Harmful if absorbed through the skin. | 【Eyes】
Causes eye irritation. Lachrymator. | 【Ingestion】
Harmful if swallowed. May cause irritation of the digestive tract. May cause nausea and vomiting. | 【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. May polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. | 【EC Risk Phrase】
