Fire fighting
For small (incipient) fires, use media such as alcohol foam, dry chemical, or carbon dioxide. For large fires, apply water from as far as possible. Use very large quantities (flooding) of water applied as a mist or spray; solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water. Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.
Fire potential
Flammable liquid.
Hazards
Vapor may travel considerable distance to source of ignition and flash back. Emits toxic fumes under fire conditions.

Health.
Exposure effects
May be harmful by inhalation, ingestion, or skin absorption. May cause irritation.

First aid
 
   Ingestion
If swallowed, wash out mouth with water provided person is conscious. Call a physician.
