TYPES OF
HAZARD/
EXPOSURE
ACUTE HAZARDS/
SYMPTOMS
PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Highly flammable.
NO open flames, NO sparks, and NO smoking.
Powder, AFFF, foam, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT GENERATION OF MISTS!

  • INHALATION
  • Drowsiness. Headache. Nausea.
    Ventilation, local exhaust, or breathing protection.
    Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
  • Redness.
    Protective gloves.
    First rinse with plenty of water, then remove contaminated clothes and rinse again.
  • EYES

  • Safety spectacles.
    First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
  • Abdominal pain. Vomiting.
    Do not eat, drink, or smoke during work.
    Rinse mouth. Do NOT induce vomiting.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Evacuate danger area! Ventilation. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place (extra personal protection: filter respirator for organic gases and vapours).
    Fireproof. Separated from oxidants. Cool.

    UN Hazard Class: 3
    UN Packing Group: II

    CHEMICAL DANGERS:
    Reacts with oxidants.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV not established.


    ROUTES OF EXPOSURE:
    The substance can be absorbed into the body by inhalation and by ingestion.

    INHALATION RISK:
    No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20C.

    EFFECTS OF SHORT-TERM EXPOSURE:
    The substance irritates the skin. The substance may cause effects on the central nervous system.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
