Hazardous Polymerization: will not occur.

Health Hazard Data
Route of Entry - Inhalation: no (sealed cells).
Route of Entry - Skin: no (sealed cells).
Route of Entry - Ingestion: no (sealed cells).
Health Hazard acute and chronic: Due to the small size and volume of the sealed cells and the
complete sealing of the materials in quartz cells the only contact that can be made to
the chemicals is through the breakage of the cells.  The quartz shards would be more hazardous
and must be handled as with any glass breakage.
Direct skin contact will cause skin irritation.

Signs and symptoms of exposure: none.
Medical Conditions aggravated by exposure: possible skin irritation.
Emergency and First Aid Procedures: In the event of breakage of any ofcells, wash with water
and safely dispose of the quartz pieces.

Precautions for Safe Handling and Use
Steps if material Released/Spill: In the event of breakage of any of cells, wash with water
and safely dispose of the quartz pieces.
Waste disposable method:  The only waste generated by the breakage would be the quartz
Dispose of the quartz pieces as you would for any broken laboratory glassware.
Precautions to be taken in Handling and Storing: none.

Control Measures
Respiratory Protection: none required.
Ventilation: none required.
