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
    The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the
    standard EN 374 derived from it.
    Handle with gloves.
  Eye protection
    Safety glasses with side-shields conforming to EN166
  Skin and body protection
    Choose body protection according to the amount and concentration of the dangerous substance at the
    work place.
  Hygiene measures
    Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at
    the end of workday.
