First Aid Measures
【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
【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.

Hazards Identification
【Ingestion】May cause irritation of the digestive tract.
【Inhalation】Causes respiratory tract irritation.
【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
sp along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers.
