TYPES OF
HAZARD/
EXPOSURE
ACUTE HAZARDS/
SYMPTOMS
PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION Above 88C explosive vapour/air mixtures may be formed. Risk of fire and explosion (see Chemical Dangers).
Above 88C use a closed system, ventilation.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT GENERATION OF MISTS! STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
  • INHALATION
  • Blue lips or finger nails. Blue skin. Dizziness. Headache. Nausea. Unconsciousness. Weakness.
    Ventilation, local exhaust, or breathing protection.
    Fresh air, rest. Refer for medical attention.
  • SKIN
  • MAY BE ABSORBED! (Further see Inhalation).
    Protective gloves. Protective clothing.
    Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
  • EYES

  • Safety goggles.
    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. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Rest. 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 absorb in saw-dust or other combustible absorbents (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    Separated from combustible and reducing substances, strong oxidants, strong acids, food and feedstuffs.
    Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
    PALE YELLOW OILY LIQUID , WITH CHARACTERISTIC ODOUR.

    PHYSICAL DANGERS:


    CHEMICAL DANGERS:
    On combustion, forms corrosive fumes including nitrogen oxides. Reacts violently with strong oxidants and reducing agents, causing fire and explosion hazard. Attacks many plastics. Forms explosive (thermally unstable) substances or mixtures with many organic and inorganic compounds like oxidants, aluminium chloride with phenol, potassium hydroxide anhydrous or with small amounts of methanol, aniline with glycerol, phosphoruspentachloride, nitric acid, sulphuric acid, potassium.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV: 1 ppm; 5 mg/m3 skin (ACGIH 1992-1993).
    PDK: 3 mg/m3 (USSR 1986).


    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 20C; on dispersing, however, much faster.

    EFFECTS OF SHORT-TERM EXPOSURE:
    The substance may cause effects on the blood cells , resulting in formation of methaemoglobin. Exposure could cause lowering of consciousness. The effects may be delayed. Medical observation is indicated.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    The substance may have effects on the blood forming organs. It may have effects on the liver.

    ENVIRONMENTAL
    DATA

    N O T E S
    Use of alcoholic beverages enhances the harmful effect. Depending on the degree of exposure, periodic medical examination is indicated. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Do NOT take working clothes home. On distillation, do NOT evaporate to dryness because of the explosion hazard.
