ACUTE HAZARDS/
SYMPTOMS
PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Flammable.
NO open flames.
Powder, water spray, foam, carbon dioxide.
EXPLOSION Above 52C explosive vapour/air mixtures may be formed.
Above 52C use a closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT GENERATION OF MISTS!

  • INHALATION
  • Cough. Sore throat.
    Ventilation, local exhaust, or breathing protection.
    Fresh air, rest.
  • SKIN
  • Redness.
    Protective gloves.
    Rinse and then wash skin with water and soap.
  • EYES
  • Redness.
    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
    Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place (extra personal protection: self-contained breathing apparatus).
    Separated from strong oxidants. Well closed. Store only if stabilized.

    UN Hazard Class: 3
    UN Packing Group: III
    Marine pollutant.
