Safety Data Sheet (SDS) - R114

RECOMMENDED USE: Refrigerant DISTRIBUTOR: Hudson Technologies Company ADDRESS: PO Box 1541 One Blue Hill Plaza Pearl River, NY 10965 EMERGENCY PHONE: 1- 800-501-4376 CHEMTREC PHONE: 1-800-424-9300 INFORMATION PHONE: 1-800-953-2244

EMERGENCY OVERVIEW: Colorless, volatile liquid with ethereal and faint sweetish odor. Non-flammable material. Contact with the liquid may cause frostbite. Overexposure to vapors by inhalation may cause dizziness and loss of concentration. At higher levels, central nervous system depression and cardiac arrhythmia may result from exposure. Vapors displace air and can cause asphyxiation in confined spaces. At higher temperatures, (>250°C), decomposition products may include Hydrochloric Acid (HCL), Hydrofluoric Acid (HF) and carbonyl halides. HAZARD CLASSIFICATION: Gases Under Pressure USDOT Hazard Class 2.2, Non-Flammable Gas SIGNAL WORD: WARNING HAZARD STATEMENTS: Gas under pressure; may explode if heated Harms public heal and the environment by destroying ozone in the upper atmosphere Harmful in contact with skin - may cause frostbite May displace oxygen and cause rapid suffocation. Inhalation of high concentrations of vapor is harmful and may cause heart irregularities, unconsciousness, or death. PRECAUTIONARY STATEMENTS PREVENTION: Do not breathe vapors. Use only with adequate ventilation - never in a closed space. Wear protective gloves. Wear eye protection. RESPONSE: If inhaled: Remove person to fresh air and keep comfortable for breathing.

Immediately call a physician. If not breathing, give artificial respiration, preferably mouth to mouth. If breathing is difficult, give oxygen. Avoid stimulants.

STORAGE: Protect from sunlight. Store in well-ventilated place. Do not heat above 120°F (50°C). Do not store in damp areas. DISPOSAL: Comply with Federal, State and local regulations. Reclaim by distillation or remove to a permitted waste disposal facility CARCINOGENICITY: Ingredients found on one of the OSHA designated carcinogen lists are listed below.

PRODUCT NAME: 1,2-Dichloro-1,1,2,2-Tetrafluoroethane SYNONYMS: R-114, REFRIGERANT 114, CFC 114 INGREDIENT NAME CAS NUMBER WEIGHT % Ingredient Name CAS Number Weight%100 1,2-Dichloro-1,1,2,2-Tetrafluoroethane (CFC-114) 76-14-2 Trace impurities and additional material names not listed above may also appear in Section 15 toward the end of this Safety Data Sheet.

SKIN: Promptly flush skin with water until all chemical is removed. If there is evidence of frostbite, bathe (do not rub) with lukewarm (not hot) water. If water is not available, cover with a clean, soft cloth or similar covering. Get medical attention if symptoms persist. EYES: Immediately flush eyes with large amounts of water for at least 15 minutes (in case of frostbite water should be lukewarm, not hot) lifting eyelids occasionally to facilitate irrigation. Get medical attention if symptoms persist. INHALATION: Immediately remove to fresh air. If breathing has stopped, give artificial respiration. Use oxygen as required, provided a qualified operator is available. Get medical attention. Do not give epinephrine (adrenaline). INGESTION: Ingestion is unlikely because of the physical properties and is not expected to be hazardous. In case of accidental ingestion, get medical attention. Do not induce vomiting unless instructed to do so by a physician. ADVICE TO PHYSICIAN: Because of the possible disturbances of cardiac rhythm, catecholamine drugs, such as epinephrine, should be used with special caution and only in situations of emergency life support. Treatment of overexposure should be directed at the control of symptoms and the clinical conditions.

FLAMMABLE LIMITS IN AIR, UPPER: N/A (% BY VOLUME) LOWER: N/A FLASH POINT: None NFPA HAZARD CLASSIFICATION HEALTH: 1 FLAMMABILITY: 0 REACTIVITY: 1 OTHER: EXTINGUISHING MEDIA: Appropriate for combustibles in the area. SPECIAL FIRE FIGHTING PROCEDURES: The product is not flammable. Use water spray to cool containers. Self-contained breathing apparatus (SCBA) is required if cylinders rupture and contents are released under fire conditions. UNUSUAL FIRE AND EXPLOSION HAZARDS: Cylinders may rupture under fire conditions. CFC 114 should not be permitted to mix with air above atmospheric pressure or at high temperatures, or in an oxygen enriched environment, since under such conditions it can become combustible in the presence of an ignition source. HAZARDOUS DECOMPOSITION PRODUCTS: Under high temperatures, this product can form hydrofluoric acid, and possibly carbonyl fluoride.

IN CASE OF SPILL OR OTHER RELEASE: (Always wear recommended personal protective equipment.) Evacuate unprotected personnel. Protected personnel should remove ignition sources and shut off leak, if without risk, and provide ventilation. Use self-contained breathing apparatus (SCBA) for large spills or releases. Unprotected personnel should not return until air has been tested and determined safe, including low- lying areas. Spills and releases may have to be reported to Federal and/or local authorities. See Section 15 regarding reporting requirements.

NORMAL HANDLING: Always wear recommended personal protective equipment. Avoid breathing vapors and liquid contact with eyes, skin or clothing. Do not puncture or drop cylinders, expose them to open flame or excessive heat. Use authorized cylinders only. Follow standard safety precautions for handling and use of compressed gas cylinders. R-114 should not be mixed with air above atmospheric pressure for leak testing or any other purpose. STORAGE RECOMMENDATIONS: Store in a cool, well-ventilated area of low fire risk and keep out of direct sunlight. Protect cylinder and its fittings from physical damage. Storage in subsurface locations should be avoided. Close valve tightly after use and when empty. Cylinder temperatures should not exceed 52° C (125° F).

ENGINEERING CONTROLS: Provide local ventilation at filling zones and areas where leakage is probable. Mechanical (general) ventilation may be adequate for other operating and storage areas. PERSONAL PROTECTIVE EQUIPMENT SKIN PROTECTION: Skin contact with refrigerant may cause frostbite. General work clothing and gloves (leather) should provide adequate protection. If prolonged contact with the liquid or gas is anticipated, insulated gloves constructed of PVA, neoprene or butyl rubber should be used. Any contaminated clothing should be promptly removed and washed before reuse. EYE PROTECTION: For normal conditions, wear safety glasses. Where there is reasonable probability of liquid contact, wear chemical safety goggles.

ADDITIONAL RECOMMENDATIONS: Where contact with liquid is likely, such as in a spill or leak, impervious boots and clothing should be worn. High dose-level warning signs are recommended for areas of principle exposure. Provide eyewash stations and quick-drench shower facilities at convenient locations. For tank cleaning operations, see OSHA regulations, 29 CFR 1910.132 and 29 CFR 1910.133.
