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. Take victim immediately to hospital. Consult a physician.
  In case of eye contact
    Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.
  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
    Material is extremely destructive to tissue of the mucous membranes and upper respiratory tract, eyes, and
    skin., Cough, Shortness of breath, Headache, Nausea
  Indication of any immediate medical attention and special treatment needed
    no data available

Section 5. FIREFIGHTING MEASURES
  Extinguishing media
  Suitable extinguishing media
    Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
  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
    Wear respiratory protection. 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.
  Environmental precautions
    Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the
    environment must be avoided.
  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 contact with skin and eyes. 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
    Avoid contact with skin, eyes and clothing. Wash hands before breaks and immediately after handling
    the product.
  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.
    Splash protection
    Material: Fluorinated rubber
    Minimum layer thickness: 0,7 mm
    Break through time: 30 min
    Material tested:Vitoject® (KCL 890 / Z677698, Size M)
    data source: KCL GmbH, D-36124 Eichenzell, phone +49 (0)6659 87300,     test method: EN374
    If used in solution, or mixed with other substances, and under conditions which differ from EN 374,
    contact the supplier of the CE approved gloves. This recommendation is advisory only and must
    be evaluated by an Industrial Hygienist familiar with the specific situation of anticipated use by our
    customers. It should not be construed as offering an approval for any specific use scenario.
  Body Protection
    Complete suit protecting against chemicals, 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 AXBEK (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).
