    Wear respiratory protection. Avoid dust formation. Avoid breathing vapors, mist or gas. Ensure adequate
    ventilation. Remove all sources of ignition. Evacuate personnel to safe areas. Avoid breathing dust.
  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
    Sweep up and shovel. 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). Keep
    in suitable, closed containers for disposal. Contain spillage, pick up with an electrically protected vacuum
    cleaner or by wet-brushing and transfer to a 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

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.
  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 particle
    respirator type N100 (US) or type P3 (EN 143) 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).
