SECTION 6: Accidental release measures
  Personal precautions, protective equipment and emergency procedures
    Use personal protective equipment. 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.
  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.
    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.
    Storage class (TRGS 510): Flammable liquids
  Specific end use(s)

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
    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).
  Control of environmental exposure
    Prevent further leakage or spillage if safe to do so. Do not let product enter drains.
