EXPOSURE
PREVENT GENERATION OF MISTS!

  • INHALATION
  • Burning sensation. Cough. Sore throat.
    Ventilation.
    Fresh air, rest. Refer for medical attention.
  • SKIN
  • MAY BE ABSORBED! Redness. Burning sensation. Pain.
    Protective gloves. Protective clothing.
    Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
  • EYES
  • Redness. Pain.
    Safety goggles or face shield.
    First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
  • Abdominal cramps. Burning sensation.
    Do not eat, drink, or smoke during work. Wash hands before eating.

    PHYSICAL DANGERS:


    CHEMICAL DANGERS:
    The substance decomposes on heating, producing toxic and corrosive fumes including hydrogen chloride (see ICSC # 0126).

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV not established.


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

    INHALATION RISK:
    No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20C.

    EFFECTS OF SHORT-TERM EXPOSURE:
    The substance severely irritates the eyes, the skin and the respiratory tract.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    PHYSICAL
    PROPERTIES
