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

  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.
    Full contact
    Material: Nitrile rubber
    Minimum layer thickness: 0,11 mm
    Break through time: 480 min
    Material tested:Dermatril® (KCL 740 / Z677272, Size M)
    Splash contact
    Material: Nitrile rubber

    data source: KCL GmbH, D-36124 Eichenzell, phone +49 (0)6659 87300     test method: EN374
    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 and safety officer 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 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).
  Control of environmental exposure
    Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into
    the environment must be avoided.
