4. FIRST AID MEASURES

A. Eye Contact ○ Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. ○ Get medical attention if irritation persists. B. Skin Contact ○ Wash off immediately with soap and plenty of water. ○ Seek immediate medical attention/advice. Remove and wash contaminated clothing before re-use..

C. Inhalation ○ Move to fresh air. If breathing is irregular or stopped, administer artificial respiration. ○ Seek immediate medical attention/advice

D. Ingestion ○ Do NOT induce vomiting. Drink 1 or 2 glasses of water. ○ Never give anything by mouth to an unconscious person. ○ Call a physician or Poison Control Center immediately. E. Most important symptoms and effects, ○ both acute and delayedprolonged or repeated exposure can cause:, Vomiting, Diarrhoea, Abdominal pain, Rats exposed to 1-methyl-2-pyrrolidinone at a concentration of 1 mg/L as an aerosol for 10 days showed depletion ofhematopoietic cells in the bone marrow and atrophy of the lymphoid tissues of the thymus, spleen, andlymph nodes

F. Physician’s Attention ○ No any special antidotal medicine is available now, should suit the remedy to the case.5. FIRE FIGHTING MEASURES

A. Autoignition temp ： 395℃

B. Flammability Limits in Air Upper / Lower : No data available / 5.9 vol %

C. Suitable Extinguishing Media ： ○ Dry sand, foam, carbon dioxide, or dry chemical powder extinguisher should be used D. Special hazards arising from the substance or mixture ○ Carbon oxides, nitrogen oxides (NOx)

E. Advice for firefighters ○ Shut off fuel as much as possible Evacuate unnecessary personnel to safe area. ○ Fire fighters should wear proper protective clothing

5

6. ACCIDENTAL RELEASE MEASURES

A. Personal precautions, protective equipment and emergency procedures ○ Use personal protective equipment. ○ Avoid breathing vapors, mist or gas. ○ Ensure adequate ventilation. ○ Remove all sources of ignition. Evacuate personnel to safe areas. ○ Beware of vapours accumulating to form explosive concentrations. Vapours can accumulate in low areas.

B. Environmental precautions : Prevent spilt solution from entering sewers, watercourses, rivers, or fields

C. Methods for Cleaning Up: ： ○ When the leak is small, wipe it with cloths. Leave the cloth in the draft, and burn it off after solvent has evaporated. ○ When the leak is large, try to stop the flow with cloths, and collect the spilt solution in an empty container as much as possible.

7. HANDLING AND STORAGE

A. Precautions for safe handling ○ Be careful in handling the container, and protect it from damages. ○ Wear proper protective clothings. ○ Use only in the well-ventilated area. ○ Seal the container after handling. ○ Avoid contact with oxidizing agents or reductants. ○ Shut off all sources of ignition. ○ The electric facility should be explosion proof ○ When moving the solution through pipings, ground the metallic part of the apparatuses, pipings and containers to prevent generation of electrostatic charges. ○ Pay attention to ventilation. This vapor is heavier than air, and easily stays at low position. ○ Do not expose to UV light. Use under tungsten or yellow light. ○ Solution should not remain in piping when it is not used. ○ Water facility should be installed at every place where the solution is used. It should facilitate measures in case of adhesion or contact with eyes.

B. Conditions for safe storage ○ Keep the container sealed, and store in a cool and dark place. ○ Keep away all sources of ignition. Do not heat. Do not let it evaporate without a reason. ○ Store in well-ventilated area.

C. Others : Follow all national and local regulations.

8. EXPORSURE CONTROLS/PERSONAL PROTECTION

B. Appropriate engineering control : When handling, try to use closed apparatuses, equipment or partial ventilator

C. Personal protective equipment○ Respiratory Protection: Under conditions of frequent use or heavy exposure, respiratory protection worn.○ Eye Protection: Safety glasses, splash resistant wear.○ Hand protection: fire-resistant clothing, gloves.○ body protection: fire-resistant wear protection
