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
    Take off contaminated clothing and shoes immediately. 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.

    Carbon oxides, Hydrogen chloride gas
  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 vapours, 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.
    For personal protection see section 8.
  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 exposure - obtain special instructions before use.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
    For precautions see section 2.2.
  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.
    Recommended storage temperature: 2 - 8 °C
  Specific end use(s)
    A part from the uses mentioned in section 1.2 no other specific uses are stipulated

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
    Tightly fitting safety goggles. Faceshield (8-inch minimum). Use equipment for eye protection
    tested and approved under appropriate government standards such as NIOSH (US) or EN
  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
    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 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).
  Control of environmental exposure
    Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into
    the environment must be avoided.
