TYPES OF
HAZARD/
EXPOSURE
ACUTE HAZARDS/
SYMPTOMS
PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Extremely 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.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT GENERATION OF MISTS!

  • INHALATION
  • Cough. Dizziness. Drowsiness. Sore throat. Unconsciousness. Vomiting.
    Ventilation, local exhaust, or breathing protection.
    Fresh air, rest. Refer for medical attention.
  • SKIN
  • Dry skin. Redness.
    Protective gloves.
    Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
  • EYES
  • Redness.
    Safety goggles.
    First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
  • (Further see Inhalation).
    Do not eat, drink, or smoke during work.
    Rinse mouth. Do NOT induce vomiting. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Evacuate danger area! Consult an expert! 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. Do NOT wash away into sewer (extra personal protection: filter respirator for organic gases and vapours).
    Fireproof. Separated from strong oxidants. Cool.

    UN Hazard Class: 3
    UN Packing Group: II

    PHYSICAL STATE; APPEARANCE:
    COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

    PHYSICAL DANGERS:
    The vapour is heavier than air and may travel along the ground; distant ignition possible, and may accumulate in low ceiling spaces causing deficiency of oxygen.

    CHEMICAL DANGERS:
    Reacts violently with oxidants causing fire and explosion hazard.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV not established.


    ROUTES OF EXPOSURE:
    The substance can be absorbed into the body by inhalation of its vapour.

    INHALATION RISK:
    A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20C.

    EFFECTS OF SHORT-TERM EXPOSURE:
    The substance irritates the eyes and the respiratory tract. Swallowing the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis. The substance may cause effects on the central nervous system. Exposure at high level may result in unconsciousness.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    The liquid defats the skin.
    PHYSICAL
    PROPERTIES
    Boiling point: 63C
    Melting point: -140C
    Relative density (water = 1): 0.7
    Solubility in water: none
    Vapour pressure, kPa at 38C: 41
    Relative vapour density (air = 1): 2.9
    Relative density of the vapour/air-mixture at 20C (air = 1): 1.8
    Flash point: -26C
    Auto-ignition temperature: 253C
    Explosive limits, vol% in air: 1.2-6.9
    ENVIRONMENTAL
    DATA

    N O T E S
    Environmental effects from the substance have not been investigated adequately. High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area.
    Transport Emergency Card: TEC (R)-534
    NFPA Code: H1; F3; R0.
