EXPOSURE


  • INHALATION

  • Ventilation.
    Fresh air, rest.
  • SKIN

  • Protective gloves.
    Rinse and then wash skin with water and soap.
  • EYES

  • Safety spectacles.
    First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION

  • Do not eat, drink, or smoke during work.
    Rinse mouth. Rest.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into covered containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place.
