  Description of first aid measures
  General advice
    Consult a physician. Show this safety data sheet to the doctor in attendance.
  If inhaled

  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.

    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 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, 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).
