|Aqueous solution prepared in 10% (volume fraction) perchloric acid to contain 4% (mass fraction) Samarium oxide.|
Transparent liquid heat fusion sealed in a quartz cell, 3 ml.
Boiling Point: 100 ░ C.
Specific Gravity: 1.0.
Vapor Pressure (mm Hg): n/a.
Melting Point: 0 ░ C.
Vapor Density: n/a.
Evaporation Rate: n/a.
Solubility in Water: soluble.
|Fire and Explosion Hazard|
Flammable limits: non-flammable.
Extinguishing Media: Same precautions as for water.
Special Fire Fighting Procedures: Same precautions as for water.
Unusual Fire and Explosion Procedures: same as for water.
Conditions to avoid: Avoid contact with incompatible materials if broken.
Incompatible Materials: Perchloric acid is incompatible with acids, combustible materials, metals, oxidizing agents, metal oxides, halo carbons, metal salts, and bases.
Hazardous Decomposition Products: Perchloric acid: can produce acid halides and oxides of chlorine.
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 of cells, 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 container. Dispose of the quartz pieces as you would for any broken laboratory glassware.
Precautions to be taken in Handling and Storing: none.
Ventilation: none required.
Protective Gloves: Chemical resistant gloves.
Eye Protection: Chemical resistant goggles.
Other protective equipment: Have immediate availability of eye wash.
