EXPOSURE
PREVENT GENERATION OF MISTS! STRICT HYGIENE!

  • INHALATION
  • Blue lips or finger nails. Blue skin. Cough. Dizziness. Headache. Laboured breathing. Sore throat.
    Local exhaust or breathing protection.
    Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
  • MAY BE ABSORBED! Redness. Pain (further see Inhalation).
    Protective gloves. Protective clothing.
    Rinse and then wash skin with water and soap. Refer for medical attention. Wear protective gloves when administering first aid.
  • EYES
  • Redness. Pain.
    Face shield or eye protection in combination with breathing protection.
    First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
  • Abdominal pain. Blue lips or fingernails. Blue skin. Dizziness. Headache. Laboured breathing.
    Do not eat, drink, or smoke during work.
    Rinse mouth. 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. Do NOT let this chemical enter the environment (extra personal protection: self-contained breathing apparatus).
    Separated from combustible and reducing substances, strong oxidants, strong bases, food and feedstuffs. Tightly closed. Cool. Dry. Keep in a well-ventilated room.
    Do not transport with food and feedstuffs.

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

    PHYSICAL DANGERS:


    CHEMICAL DANGERS:
    The substance decomposes on contact with strong oxidants, sulfuric acid, reducing agents, acids or bases producing toxic fumes , causing fire and explosion hazard. Attacks some forms of plastics, rubber, and coatings.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV (as TWA): 2 ppm; 11 mg/m3 (skin) (ACGIH 1991-1992).


    ROUTES OF EXPOSURE:
    The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.

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

    EFFECTS OF SHORT-TERM EXPOSURE:
    The substance irritates the eyes, the skin, and the respiratory tract. The substance may cause effects on the blood , resulting in formation of methaemoglobin. Medical observation is indicated.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    The substance may have effects on the liver and blood , resulting in liver injury or anemia.
