Fire.
Flash Point,°C
39
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
Combustible liquid. Vapor may travel considerable distance to source of ignition and flash back.
Hazards
Emits toxic fumes under fire conditions.

Health.
Exposure effects
Harmful if swallowed, inhaled, or absorbed through skin. Symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. Inhalation may result in spasm, inflammation and edema of the larynx and bronchi, chemical pneumonitis, and pulmonary edema. Material is extremely destructive to tissue of the mucous membranes and upper respiratory tract, eyes, and skin.

First aid
 
   Ingestion
If swallowed, wash out mouth with water provided person is conscious. Call a physician.
   Inhalation
If inhaled, remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen.
   Skin
In case of contact, immediately wash skin with soap and copious amounts of water. Remove contaminated clothing and shoes. Call a physician.
   Eyes
In case of contact with eyes, flush with copious amounts of water for at least 15 minutes. Assure adequate flushing by separating the eyelids with fingers. Call a physician.
