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.
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

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

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.
