3 - Hazards Identification

SPECIAL INDICATION OF HAZARDS TO HUMANS AND THE ENVIRONMENT
Reacts violently with water. Causes burns. Irritating to
respiratory system.

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 EYE CONTACT
Assure adequate flushing of the eyes by separating the eyelids
with fingers.

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
Unsuitable: Do not use water.

SPECIAL RISKS
Specific Hazard(s): Emits toxic fumes under fire conditions.
Explosion Hazards: Container explosion may occur under fire
conditions.

SPECIAL PROTECTIVE EQUIPMENT FOR FIREFIGHTERS
Wear self-contained breathing apparatus and protective clothing
to prevent contact with skin and eyes.

6 - Accidental Release Measures

PERSONAL PRECAUTION PROCEDURES TO BE FOLLOWED IN CASE OF LEAK OR SPILL
Evacuate area.

PROCEDURE(S) OF PERSONAL PRECAUTION(S)
Wear self-contained breathing apparatus, rubber boots, and heavy

No data available.

13 - Disposal Considerations

SUBSTANCE DISPOSAL
For small quantities: cautiously add to a large stirred excess of
water. Adjust the pH to neutral, separate any insoluble solids or
liquids and package them for hazardous-waste disposal. Flush the
aqueous solution down the drain with plenty of water. The
hydrolysis and neutralization reactions may generate heat and
fumes which can be controlled by the rate of addition. Observe all
federal, state, and local environmental regulations.
