Hazards Identification Emergency overview COMPRESSED GAS. State of matter: gaseous Colour: colourless Odour: faint odour, ether-like Potential health effects Acute toxicity: Ingestion may cause gastrointestinal disturbances. Irritation / corrosion: May cause slight irritation to the eyes. May cause slight irritation to the skin. Not irritating to the eyes. Not irritating to the skin. Assessment other acute effects: Based on the available information there is no specific target organ toxicity to be expected after a single exposure. Sensitization: The chemical structure does not suggest a sensitizing effect. Chronic toxicity: Carcinogenicity: The chemical structure does not suggest a specific alert for such an effect. Repeated dose toxicity: Repeated exposure to the substance by dermal administration leads to effects similar to those found after single exposure. Repeated exposure to the substance by inhalative administration leads to

2 Revision date : 2012/07/31 Page: 2/7 effects similar to those found after single exposure. Repeated exposure to the substance by oral administration leads to effects similar to those found after single exposure. Reproductive toxicity: The chemical structure does not suggest a specific alert for such an effect. Teratogenicity: The chemical structure does not suggest a specific alert for such an effect. Genotoxicity: The chemical structure does not suggest a specific alert for such an effect. Signs and symptoms of overexposure: Overexposure may cause:, coma, lethargy, confusion, cardiac disorders, dizziness, tremors Symptoms can appear later. Potential environmental effects Aquatic toxicity: There is a high probability that the product is not acutely harmful to aquatic organisms. Degradation / environmental fate: Not readily biodegradable (by OECD criteria). 3. Composition / Information on Ingredients CAS Number Content (W/W) Hazardous ingredients >= <= % HFC-134A 4. First-Aid Measures General advice: Immediately remove contaminated clothing. If danger of loss of consciousness, place patient in recovery position and transport accordingly. Apply artificial respiration if necessary. Never induce vomiting or give anything by mouth if the victim is unconscious or having convulsions. If inhaled: Keep patient calm, remove to fresh air. If difficulties occur after vapour/aerosol has been inhaled, remove to fresh air and seek medical attention. If not breathing, give artificial respiration. If necessary, give oxygen. If on skin: Wash off thoroughly with ample water. If symptoms persist, seek medical advice. Cover thermal burns with sterile dressing. If in eyes: Immediately wash affected eyes for at least 15 minutes under running water with eyelids held open, consult an eye specialist. If swallowed: Ingestion is not likely in the available physical form. If ingested, seek medical attention. Note to physician Treatment: Treat according to symptoms (decontamination, vital functions), no known specific antidote. 5. Fire-Fighting Measures Flash point: Autoignition: > 750 C Not determinable.

3 Revision date : 2012/07/31 Page: 3/7 Lower explosion limit: Suitable extinguishing media: water spray, carbon dioxide, foam, dry powder Unsuitable extinguishing media for safety reasons: water jet Additional information: Use extinguishing measures to suit surroundings. not determined Hazards during fire-fighting: carbon monoxide, carbon dioxide, hydrogen fluoride, The substances/groups of substances mentioned can be released in case of fire. Protective equipment for fire-fighting: Firefighters should be equipped with self-contained breathing apparatus and turn-out gear. Further information: Dispose of fire debris and contaminated extinguishing water in accordance with official regulations. Sealed containers should be protected against heat as this results in pressure build-up. Cool endangered containers with water-spray. 6. Accidental release measures Personal precautions: Use personal protective clothing. Ensure adequate ventilation. Environmental precautions: Do not discharge into the subsoil/soil. Do not empty into drains. Cleanup: Dispose of absorbed material in accordance with regulations. For large amounts: Pump off product. For residues: Allow to evaporate. 7. Handling and Storage Handling General advice: Ensure thorough ventilation of stores and work areas. Provide good room ventilation even at ground level (vapours are heavier than air). Handle and open container with care. Protect against heat. Protection against fire and explosion: Keep away from heat. Vapours are heavier than air. Storage General advice: Keep in a cool, well-ventilated place. Keep away from heat. Keep at temperature not exceeding 50 C. Storage incompatibility: General advice: Segregate from foods and animal feeds. Segregate from combustible materials. 8. Exposure Controls and Personal Protection

4 Revision date : 2012/07/31 Page: 4/7 Personal protective equipment Respiratory protection: Wear respiratory protection if ventilation is inadequate. Self-contained breathing apparatus. Hand protection: Chemical resistant protective gloves Eye protection: Wear face shield or tightly fitting safety goggles (chemical goggles) if splashing hazard exists. General safety and hygiene measures: Wearing of closed work clothing is required additionally to the stated personal protection equipment. Avoid contact with the skin, eyes and clothing. Do not inhale gases/vapours/aerosols. When using, do not eat, drink or smoke. Hands and/or face should be washed before breaks and at the end of the shift. At the end of the shift the skin should be cleaned and skin-care agents applied. 9.
