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
    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
    impervious 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).
