TYPES OF
HAZARD/
EXPOSURE
ACUTE HAZARDS/
SYMPTOMS
PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Flammable.
NO open flames, NO sparks, and NO smoking.
Powder, AFFF, foam, carbon dioxide.
EXPLOSION Above 31°C explosive vapour/air mixtures may be formed.
Above 31°C use a closed system, ventilation, and explosion-proof electrical equipment. Prevent build-up of electrostatic charges (e.g., by grounding).
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT GENERATION OF MISTS!

  • INHALATION
  • Ataxia. Cough. Dizziness. Drowsiness. Headache. Sore throat. Unconsciousness.
    Ventilation, local exhaust, or breathing protection.
    Fresh air, rest. Half-upright position. Refer for medical attention.
  • SKIN
  • Dry skin.
    Protective gloves. Protective clothing.
    Remove contaminated clothes. Rinse and then wash skin with water and soap.
  • EYES
  • Redness. Pain.
    Safety spectacles.
    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
    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 let this chemical enter the environment (extra personal protection: A/P2 filter respirator for organic vapour and harmful dust).
    Fireproof. Separated from strong oxidants, acids. Cool. Keep in the dark. Store only if stabilized.

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

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

    CHEMICAL DANGERS:
    The substance can form explosive peroxides. Reacts violently with acids and strong oxidants causing fire and explosion hazard.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV: 50 ppm; 246 mg/m3 (skin) (ACGIH 1993).


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

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

    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 far above the OEL may result in unconsciousness.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    Repeated or prolonged contact with skin may cause dermatitis.

    ENVIRONMENTAL
    DATA
    This substance may be hazardous to the environment; special attention should be given to water organisms, and birds.
    N O T E S
    An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. Check for peroxides prior to distillation; eliminate if found.
