Section 5. FIRE-FIGHTING MEASURES
  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 protective equipment for fire-fighters
    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
    Use personal protective equipment. 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.
  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).

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
    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. Store in cool place.
    Store under inert gas. Moisture sensitive.

Section 8. EXPOSURE CONTROLS/PERSONAL PROTECTION
  Personal protective equipment
  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).
  Hand 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.
  Eye 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 and 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.
  Hygiene measures
    Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at
    the end of workday.
