EXPOSURE
STRICT HYGIENE!

  • INHALATION
  • Burning sensation. Cough. Sore throat. Shortness of breath.
    Local exhaust or breathing protection.
    Fresh air, rest. Refer for medical attention.
  • SKIN
  • Redness. Pain.
    Protective gloves.
    Remove contaminated clothes. Rinse skin with plenty of water or shower.
  • EYES
  • Redness. Pain. Severe deep burns.
    Safety goggles, or face shield.
    First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
  • Sore throat. Burning sensation. Abdominal pain. Abdominal cramps. Nausea. Vomiting.
    Do not eat, drink, or smoke during work.
    Rinse mouth. Do NOT induce vomiting. Give nothing to drink. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Collect leaking liquid in sealable containers. Cautiously neutralize spilled liquid with weak alkaline solution, e.g. disodium carbonate. Then wash away with plenty of water.
