Material Safety Data Sheet Section 1: Chemical Product and Company Information Identity: RM-TX, RM-HX, UR-TX, UR-HX Hexane Reference Cell. Cell Identity: 'Hex' and 'Tol/Hex' . Manufactured by: Starna Scientific Ltd 52/54 Fowler Road, Hainault, Essex, England. Phone: +44 (0)20 8501 5550. Date of preparation:31 July 2007. Prepared by: John P. Hammond CSci CChem FRSC Section 2: Composition Reference Cell contains: ‘HEX’ Reference Cell contains: Less than 3 ml of n-Hexane ‘TOL/HEX’ Reference Cell contains: Less than 3 ml of n-Hexane containing less than 200 ppm Toluene CAS No: 110-54-3 Section 3: Hazards Identification Under USA regulations, MSDSs are not required for these materials, and the information provided below is additional safety data as a service to our customers. Our reference cells are a fully-enclosed, manufactured item intended as an end-use product for customers. Therefore, our ‘sealed-cell’ references are not classified as a "hazardous chemical" and are not treated as such under the U.S. OSHA Hazardous Communications Rule. ‘Sealed-cell’ references are considered "articles" within the meaning of 29 CFR Section 1910.1200(c), since they are formed to a specific shape or design during manufacture, have an end-use dependent upon their shape or design, and do not release or otherwise result in exposure to hazardous chemicals under normal conditions of use. 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. Signs and symptoms of exposure: none. Medical Conditions aggravated by exposure: none. Section 4: First Aid Measures Under normal circumstances no measures are required for contact with the quartz cell. In the event of breakage of any of cells, wash with water and safely dispose of the quartz pieces. If contact is made with the cell liquid by breakage of the cell, the following apply. Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention immediately. Ingestion: If swallowed, DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything by mouth to an unconscious person. Get medical attention immediately. Skin Contact: Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing. Get medical attention immediately. Eye contact : Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately. Section 5: Fire Fighting Measures In the event of the heat from a fire causing rupture of the quartz cell, the small volumes of the cell contents involved would not contribute to the incident or add any significant risk, and the measures shown below are for reference if the material is involved in a larger conflagration. Suitable extinguishing agents: Carbon Dioxide, extinguishing powder, or water jet. Protective equipment: Wear full protective clothing, and a self-contained breathing apparatus Section 6: Accidental Release Measures Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in section 8. Spill: Due to the small volumes involved and the volatile nature of the contents, it is expected that evaporation will have occurred before any remedial action can be taken. Section 7: Handling and Storage When not being used for measurement, store closed in provided foam filled wooden box. Protect from freezing. Section 8: Exposure Controls, Personal Protection Under normal use, no protective measures are required. In the event of a breakage, the following will apply to any liquid released. Respiratory Protection: none required. Ventilation: none required. Protective Gloves: Chemical resistant gloves. Eye Protection: Chemical resistant goggles. Other protective equipment: Have immediate availability of eyewash. Section 9: Physical and Chemical Properties Appearance: Transparent liquid heat fusion sealed in a quartz cell, 3ml. Boiling Point: 69 °C. Specific Gravity: 0.66 Vapour Pressure (mm Hg): n/a. Melting Point: -95 °C. Vapour Density: (Air = 1): 3.0 Evaporation Rate: (BuAc = 1): 9 Solubility in Water: Insoluble in water Section 9: Fire and Explosion Hazard: Flash point: -23 °C Flammable limits: air % by volume: lel: 1.2 uel: 7.7 Section 11: Stability and Reactivity Stability: stable under normal operating conditions. Conditions to avoid: Avoid contact with incompatible materials if broken. Incompatible Materials: Hexane: Strong oxidisers. Hazardous Decomposition Products: Hazardous Polymerization: Section 12: Toxicology Information Not toxic in available volumes. Oral rat LD50: 28710 mg/kg.  Carcinogenicity: none known . Section 13: Ecological Information Under normal conditions of use, these ‘sealed-cell’ references do not constitute any risk or hazard to the environment. If broken, evaporation will quickly remove any risk of liquid contents reaching ground water, water bodies or sewage system. Section 14: Disposal Considerations Incineration: Never incinerate ‘sealed-cell’ references. Landfill: Never dispose of  ‘sealed-cell’ references as landfill. Recycling: ‘Sealed-cell’ references must be recycled. Contact local Starna dealer for information. Starna Scientific has a recycling protocol for all types of returned ‘sealed-cell’ references. Section 15: Transport Information Land transport ARD/RID and GGVS/GGVE (cross-border/domestic) ADR/RID-GGVS/E Class:None Maritime transport IMDG/GGVSea IMDG/GGVSea Class:None Air transport ICAO-TI and IATA-DGR ICAO/IATA Class: None Section 16: Regulatory information Designed according to EC guidelines: Observe the normal safety regulations when handling chemicals. This ‘sealed-cell’ reference is not subject to classification according to EC lists and other sources of literature known to us. The product is not subject to identification regulations under EC Directives and the Ordinance on Hazardous Materials (German GefStoffV). Section 17: Other information Other: none.
