  In case of skin contact
    Take off contaminated clothing and shoes immediately. Wash off with soap and plenty of water. Consult a
    physician.
  In case of eye contact
    Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.

    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). Do not flush with water.
  Reference to other sections
    For disposal see section 13.

    charge.
    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.
    Never allow product to get in contact with water during storage.
    Recommended storage temperature: 2 - 8 °C

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
    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
    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 contact
    Material: butyl-rubber
    Minimum layer thickness: 0,3 mm
    Break through time: 10 min
    Material tested:Butoject® (KCL 897 / Z677647, 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 and safety officer 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 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.
