Ingestion
Seek medical assistance.

Inhalation
Remove to fresh air. If breathing has stopped, give artificial respiration. If breathing is difficult, give oxygen.

Skin
Remove contaminated clothing and shoes. Flush with water.

Eyes
Flush with water for at least 15 min., lifting lids occasionally.

Storage
Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Flammables-area.

Handling
Wash thoroughly after handling. Use with adequate ventilation. Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Avoid contact with heat, sparks and flame. Avoid ingestion and inhalation. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.

Inhalation
Vapors may cause dizziness or suffocation. May cause irritation or burns.

Skin
May cause irritation or burns.

Eyes
See Skin.

Ingestion
Causes respiratory tract irritation. Vapors may cause dizziness or suffocation.

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.
