Section 4. FIRST AID MEASURES
  Description of first aid measures
  General advice
    Consult a physician. Show this safety data sheet to the doctor in attendance.
  If inhaled
    If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician.
  In case of skin contact
    Wash off with soap and plenty of water. Consult a physician.
  In case of eye contact
    Flush eyes with water as a precaution.
  If swallowed
    Do NOT induce vomiting. Never give anything by mouth to an unconscious person. Rinse mouth with
    water. Consult a physician.
  Most important symptoms and effects, both acute and delayed
    To the best of our knowledge, the chemical, physical, and toxicological properties have not been
    thoroughly investigated.
  Indication of any immediate medical attention and special treatment needed
    no data available

Section 5. FIREFIGHTING MEASURES
  Extinguishing media
  Suitable extinguishing media
    For small (incipient) fires, use media such as "alcohol" foam, dry chemical, or carbon dioxide. For large
    fires, apply water from as far as possible. Use very large quantities (flooding) of water applied as a mist or
    spray; solid streams of water may be ineffective. Cool all affected containers with flooding quantities of
    water.
  Special hazards arising from the substance or mixture
    Carbon oxides
  Advice for firefighters
    Wear self contained breathing apparatus for fire fighting if necessary.
  Further information
    Use water spray to cool unopened containers.

---

Section 6. ACCIDENTAL RELEASE MEASURES
  Personal precautions, protective equipment and emergency procedures
    Avoid breathing vapors, mist or gas. Remove all sources of ignition. Beware of vapours accumulating to
    form explosive concentrations. Vapours can accumulate in low areas.
  Environmental precautions
    Prevent further leakage or spillage if safe to do so. Do not let product enter drains.
  Methods and materials for containment and cleaning up
    Contain spillage, and then collect with an electrically protected vacuum cleaner or by wet-brushing and
    place in container for disposal according to local regulations (see section 13).
  Reference to other sections
    For disposal see section 13.

Section 7. HANDLING AND STORAGE
  Precautions for safe handling
    Avoid inhalation of vapour or mist.
    Keep away from sources of ignition - No smoking.Take measures to prevent the build up of electrostatic
    charge.
  Conditions for safe storage, including any incompatibilities
    Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Containers which are
    opened must be carefully resealed and kept upright to prevent leakage.
  Specific end use(s)
    no data available

Section 8. EXPOSURE CONTROLS/PERSONAL PROTECTION
  Control parameters
  Components with workplace control parameters
  Exposure controls
  Appropriate engineering controls
    Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and
    at the end of workday.
  Personal protective equipment
  Eye/face protection
    Face shield and safety glasses Use equipment for eye protection tested and approved under
    appropriate government standards such as NIOSH (US) or EN 166(EU).
  Skin protection
    Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique
    (without touching glove's outer surface) to avoid skin contact with this product. Dispose of
    contaminated gloves after use in accordance with applicable laws and good laboratory practices.
    Wash and dry hands.
    The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and
    the standard EN 374 derived from it.
  Body Protection
    Impervious clothing., Flame retardant antistatic protective clothing, The type of protective
    equipment must be selected according to the concentration and amount of the dangerous
    substance at the specific workplace.
  Respiratory protection
    Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator
    with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup
    to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air
    respirator. Use respirators and components tested and approved under appropriate government
    standards such as NIOSH (US) or CEN (EU).
