Section 3: Hazard Identification


May be harmful by inhalation, ingestion, or skin absorption.  To the best of
our knowledge, the toxicology of this chemical has not been fully investigated.

Eye: Causes eye irritation.

Skin: May cause skin irritation.

Ingestion: May be harmful by ingestion.

Inhalation: May be irritating to mucous membranes and upper respiratory tract.

Section 4: First Aid Measures


Eyes: Rinse with copious amounts of water for several minutes, removing contact
lenses, if any, after the first 1-2minutes and continue flushing for several
more minutes.  If irritation occurs, seek medical attention, preferably an
ophthalmologist.

Skin: Immediately wash with plenty of soap and water.  Remove contaminated
clothing and shoes.  Seek medical attention if irritation persists.  Wash
clothing before reuse, and discard items which cannot be decontaminated,
such as shoes, belts and watchbands.

Ingestion: No emergency medical attention needed.

Inhalation: Move victim to fresh air.  If effects occur, seek medical attention.

Notes to Physician: There is no specific antidote. Treat symptomatically and
supportively.
