HAZARDS IDENTIFICATION Specific hazards Rapid evaporation of the liquid may cause frostbite. Vapours are heavier than air and can cause suffocation by reducing oxygen available for breathing. May cause cardiac arrhythmia. 4. FIRST AID MEASURES General advice : Never give anything by mouth to an unconscious person. When symptoms persist or in all cases of doubt seek medical advice. Inhalation : Remove from exposure, lie down. Artificial respiration and/or oxygen may be 1/7

2 necessary. Consult a physician. Skin contact : Take off all contaminated clothing immediately. Flush area with lukewarm water. Do not use hot water. If frostbite has occurred, call a physician. Eye contact : Hold eyelids apart and flush eyes with plenty of water for at least 15 minutes. Get medical attention. Ingestion : Is not considered a potential route of exposure. Notes to physician Treatment : Do not give adrenaline or similar drugs. 5. FIRE-FIGHTING MEASURES Specific hazards during fire fighting Special protective equipment for fire-fighters : pressure build-up : In the event of fire, wear self-contained breathing apparatus. Further information : Use extinguishing measures that are appropriate to local circumstances and the surrounding environment. Cool containers / tanks with water spray. 6. ACCIDENTAL RELEASE MEASURES Personal precautions : Evacuate personnel to safe areas. Ventilate the area. Refer to protective measures listed in sections 7 and 8. Environmental precautions : Should not be released into the environment. Methods for cleaning up : Evaporates. 7. HANDLING AND STORAGE Handling Advice on safe handling : Avoid breathing vapours or mist. Avoid contact with skin, eyes and clothing. Provide sufficient air exchange and/or exhaust in work rooms. For personal protection see section 8. Advice on protection against fire and explosion : No special protective measures against fire required. Storage Requirements for storage areas and containers : Keep container tightly closed in a dry and well-ventilated place. Store in original container. Keep at temperature not exceeding 52 C. 8. EXPOSURE CONTROLS/PERSONAL PROTECTION 2/7

3 Occupational Exposure Limits No information available. Engineering measures Ensure adequate ventilation, especially in confined areas. Personal protective equipment Respiratory protection : For rescue and maintenance work in storage tanks use self-contained breathing apparatus. Vapours are heavier than air and can cause suffocation by reducing oxygen available for breathing. Hand protection Eye protection Hygiene measures : Heat insulating gloves : Safety glasses : Handle in accordance with good industrial hygiene and safety practice. 9.
