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. Prevent build-up of electrostatic charges (e.g., by grounding). 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
  • Cough.
    Ventilation, local exhaust, or breathing protection.
    Fresh air, rest.
  • SKIN
  • Redness.
    Protective gloves.
    Remove contaminated clothes. 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
  • Drowsiness. Laboured breathing. Nausea.

    Rinse mouth. Do NOT induce vomiting. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    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.
    Fireproof. Separated from strong oxidants. Cool. Keep in the dark. Well closed. Store only if stabilized.

    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. As a result of flow, agitation, etc., electrostatic charges can be generated.

    CHEMICAL DANGERS:
    The substance can form explosive peroxides. The substance may polymerize under certain conditions. Reacts with strong oxidants causing fire and explosion hazard.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV: 300 ppm; 1010 mg/m3 (as TWA) (ACGIH 1992-1993).


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

    INHALATION RISK:
    A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20C.

    EFFECTS OF SHORT-TERM EXPOSURE:
    The substance irritates the eyes, the skin and the respiratory tract. Swallowing the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    PHYSICAL
    PROPERTIES
    Boiling point: 83C
    Melting point: -104C
    Relative density (water = 1): 0.81
    Solubility in water: none
    Vapour pressure, kPa at 20C: 8.9
    Relative vapour density (air = 1): 2.8
    Relative density of the vapour/air-mixture at 20C (air = 1): 1.16
    Flash point: -6C (c.c.)C
    Auto-ignition temperature: 310C
    Explosive limits, vol% in air: 1.2-4.8 (at 100C)
    Octanol/water partition coefficient as log Pow: 2.86
    ENVIRONMENTAL
    DATA
    This substance may be hazardous to the environment; special attention should be given to the water.
    NOTES
    Check for peroxides prior to distillation; render harmless if positive.
