3 - Hazards Identification
SPECIAL INDICATION OF HAZARDS TO HUMANS AND THE ENVIRONMENT
Irritating to eyes, respiratory system and skin.
4 - First Aid Measures
AFTER INHALATION
If inhaled, remove to fresh air. If not breathing give
artificial respiration. If breathing is difficult, give oxygen.
AFTER SKIN CONTACT
In case of skin contact, flush with copious amounts of water for
at least 15 minutes. Remove contaminated clothing and shoes.

separating the eyelids with fingers. Call a physician.
AFTER INGESTION
If swallowed, wash out mouth with water provided person is
conscious. Call a physician. Do not induce vomiting.
5 - Fire Fighting Measures
CONDITIONS OF FLAMMABILITY
Water hydrolyzes material liberating acidic gas which in contact
with metal surfaces can generate flammable and/or explosive
hydrogen gas.
EXTINGUISHING MEDIA

foam.
Unsuitable: Do not use water.
SPECIAL RISKS
Specific Hazard(s): Combustible liquid. Emits toxic fumes under
fire conditions.
SPECIAL PROTECTIVE EQUIPMENT FOR FIREFIGHTERS
Wear self-contained breathing apparatus and protective clothing
to prevent contact with skin and eyes.
