3 - Hazards Identification



SPECIAL INDICATION OF HAZARDS TO HUMANS AND THE ENVIRONMENT

   Harmful by inhalation, in contact with skin and if swallowed.

   Contact with acids liberates very toxic gas. Harmful to aquatic

   organisms, may cause long-term adverse effects in the aquatic

   environment.





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.

   Call a physician.



AFTER EYE CONTACT

   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.



AFTER INGESTION

   If swallowed, wash out mouth with water provided person is

   conscious. Call a physician.

5 - Fire Fighting Measures



EXTINGUISHING MEDIA

   Suitable: Carbon dioxide, dry chemical powder, or appropriate

   foam.



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
