Caution! May cause eye, skin, and respiratory tract irritation. Hygroscopic (absorbs

moisture from the air). The toxicological properties of this material have not been fully

investigated.

Target Organs: No data found.

Potential Health Effects

Eye: May cause eye irritation. Causes redness and pain.

Skin: May cause skin irritation. May cause an allergic reaction in certain individuals.

Ingestion: May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May be

harmful if swallowed.

Inhalation: May cause respiratory tract irritation. May be harmful if inhaled.

Chronic: No information found.





                         Section 4 - First Aid Measures







Eyes: In case of contact, immediately flush eyes with plenty of water for a t least 15

minutes. Get medical aid.

Skin: In case of contact, flush skin with plenty of water. Remove contaminated clothing and

shoes. Get medical aid if irritation develops and persists. Wash clothing before reuse.

Ingestion: If swallowed, do not induce vomiting unless directed to do so by medical

personnel. Never give anything by mouth to an unconscious person. Get medical aid.

Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If

breathing is difficult, give oxygen. Get medical aid.

Notes to Physician: Treat symptomatically and supportively.





                      Section 5 - Fire Fighting Measures







General Information: As in any fire, wear a self-contained breathing apparatus in

pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a

fire, irritating and highly toxic gases may be generated by thermal decomposition or

combustion. Substance is noncombustible.
