1 SAFETY DATA SHEET 1. Identification of the substance/preparation and of the company/undertaking Identification of the product Catalogue No: P20047 ID No.: Product name: Ether solvent BP/BS579 (diethyl ether) Manufacturer/supplier identification Company: VWR International Ltd, Merck House, Poole, Dorset, BH15 1TD, England Telephone : +44 (0) Telefax : +44 (0) Emergency telephone No.: +44 (0) Composition/information on ingredients Chemical characterization Organic solvent Product name: Diethyl ether CAS number: EC-No.: Hazards identification Extremely flammable. May form explosive peroxides. Harmful if swallowed. Repeated exposure may cause skin dryness or cracking. Vapours may cause drowsiness and dizziness. 4. First aid measures - Eye contact: Irrigate thoroughly with water for at least 10 minutes. OBTAIN MEDICAL ATTENTION. - Inhalation: Remove from exposure, rest and keep warm. In severe cases obtain medical attention. - Skin contact: Wash off skin thoroughly with water. Remove contaminated clothing and wash before

2 re-use. Unless contact has been slight, OBTAIN MEDICAL ATTENTION. - Ingestion: Wash out mouth thoroughly with water and give plenty of water to drink. OBTAIN MEDICAL ATTENTION. 5. Fire-fighting measures Special risks: Extremely flammable. Vapour/air mixture explosive. Suitable extinguishing media: Dry powder, carbon dioxide or vaporising liquids 6. Accidental release measures Shut off all sources of ignition. Inform others to keep at a safe distance. Wear appropriate protective clothing. Absorb on an inert absorbent, (e.g. BDH Spillage absorption granules), transfer to a suitable container and arrange removal by disposal company. Wash site of spillage thoroughly with water and detergent. For large spillages liquids should be contained with sand or earth and both liquids and solids transferred to salvage containers. Any residues should be treated as for small spillages. 7. Handling and storage Handling: Do not breathe vapour. Care should be taken to remove any peroxides present before distilling to low volume. Take precautions against static discharge. All electrical equipment must be flameproofed. Do not empty into drains. Unsuitable working materials: zinc Storage: Store at room temperature (15 to 25 C recommended). Keep well closed and protected from direct sunlight and moisture. Store small containers in suitable flammable liquid storage cabinets when not in use. Larger drums (200l) must be kept in purpose-built stores. 8. Exposure controls/personal protection As appropriate to the situation and the quantity handled. Engineering methods to control or prevent exposure are preferred. Methods could include process enclosure or mechanical ventilation. - Respirator: Self-contained breathing apparatus

3 - Ventilation: Fume cupboard, flameproof - Gloves: Nitrile (Change gloves regularly.), PE/EVAL (Silver Shield). - Eye Protection: Goggles or face-shield - Other Precautions: Plastic apron, sleeves, boots - if handling large quantities See section 15 for UK exposure limits. 9.

Stability and reactivity light-sensitive, sensitive to air. Formation of peroxides possible. explosible with air in a vaporous/gaseous state. Substances to be avoided halogens, halogen-halogen compounds, nonmetals, nonmetallic oxyhalides, strong oxidizing agents, chromyl chloride, turpentine oils and/or turpentine substitutes, nitrates, metallic chlorides. Stabilizer: 2,6-Di-tert.-butyl-4-methylphenol (BHT) Hazardous decomposition products: peroxides 11. Toxicological information After ingestion and inhalation: mucosal irritation, euphoria, ataxia (impaired locomotor coordination), inebriation, unconsciousness, coma. Risk of aspiration upon vomiting. Cannot be excluded: respiratory paralysis, death. After long-term exposure to the chemical: lack of appetite, constipation, allergic reactions, dermatitis.

4 Degreasing effect on the skin, possibly followed by secondary inflammation. - After eye contact: Irritation. Further data LD mg/kg oral, rat. LC mg/l inhalation, rat. No evidence of carcinogenic properties. Evidence of mutagenic effects. 12. Ecological information Bioaccumulation potential: low (Log Pow <2). Biological degradability: poor. Low aquatic toxicity. Risk of formation of explosive vapours above water surface. 13. Disposal considerations Chemical residues are generally classified as special waste, and as such are covered by regulations which vary according to location. Contact your local waste disposal authority for advice, or pass to a chemical disposal company. Rinse out empty containers thoroughly before returning for recycling. When recovery and recycling is not possible, incineration in a high temperature incinerator is the recommended method of disposal. 14.
