3 - Hazards Identification
SPECIAL INDICATION OF HAZARDS TO HUMANS AND THE ENVIRONMENT
Harmful by inhalation, in contact with skin and if swallowed.
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
In case of contact, immediately flush eyes with copious amounts
of water for at least 15 minutes.
AFTER INGESTION
If swallowed, wash out mouth with water provided person is
conscious. Call a physician.

SIGNS AND SYMPTOMS OF EXPOSURE
To the best of our knowledge, the chemical, physical, and
toxicological properties have not been thoroughly investigated.
ROUTE OF EXPOSURE
Multiple Routes: May be harmful by inhalation, ingestion, or
skin absorption. May cause irritation.
12 - Ecological Information
No data available.
13 - Disposal Considerations
SUBSTANCE DISPOSAL
Treat a dilute basic solution (pH 10-11) of the material with a
50% excess of commercial laundry bleach. Control the temperature
ALDRICH - 119318 www.sigma-aldrich.com Page 3
by the addition rate of bleach and adjust pH if necessary. Let
stand overnight. Cautiously adjust solution to pH 7. Vigorous
evolution of gas may occur. Filter any solids for burial in a
chemical landfill. Precipitate any heavy metals by addition of
sulfide and isolate for burial. Additional equivalents of
hypochlorite may be needed if the metal can be oxidized to a
higher valence state. For metal carbonyls, the reaction should be
carried out under nitrogen. Observe all federal, state, and local
environmental regulations.
