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 contact, immediately wash skin with soap and copious
amounts of water.
AFTER EYE CONTACT
Contamination of the eyes should be treated by immediate and
prolonged irrigation with copious amounts of water. Assure
adequate flushing of the eyes by separating the eyelids with
fingers.

If swallowed, wash out mouth with water provided person is
conscious. Call a physician.
GENERAL INFORMATION
Contamination of the eyes should be treated by immediate and
prolonged irrigation with copious amounts of water.
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
Suitable: Carbon dioxide, dry chemical powder, or appropriate
foam.
Unsuitable: Do not use water.
SPECIAL RISKS
Specific Hazard(s): 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.
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
rubber gloves.
METHODS FOR CLEANING UP

11 - Toxicological Information
SIGNS AND SYMPTOMS OF EXPOSURE
Material is extremely destructive to tissue of the mucous
membranes and upper respiratory tract, eyes, and skin. Depending
on the intensity and duration of exposure, effects may vary from
mild irritation to severe destruction of tissue. 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
larynxand bronchi, chemical pneumonitis, and pulmonary edema. To
the best of our knowledge, the chemical, physical, and
toxicological properties have not been thoroughly investigated.
ROUTE OF EXPOSURE
