EXPOSURE
PREVENT GENERATION OF MISTS!

  • INHALATION
  • Cough. Sore throat.
    Ventilation, local exhaust, or breathing protection.
    Fresh air, rest. Refer for medical attention.
  • SKIN
  • Redness. Roughness.
    Protective gloves.
    Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
  • EYES
  • Redness. Pain.
    Safety goggles.
    First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
  • Vomiting.
    Do not eat, drink, or smoke during work.
    Rinse mouth. Give plenty of water to drink. 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. If temperature is less than 17C, sweep spilled substance into sealable containers and remove to safe place (extra personal protection: self-contained breathing apparatus).
    Separated from strong oxidants, acids, food and feedstuffs.
    Do not transport with food and feedstuffs.
    UN Hazard Class: 6.1
    UN Packing Group: III
    Marine pollutant.

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

    PHYSICAL DANGERS:


    CHEMICAL DANGERS:
    The substance decomposes on heating or on burning, producing toxic and irritating fumes (phosgene, chlorine and hydrogen chloride). Reacts violently with oxidants, acids, and acid fumes.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV: 5 ppm; 37 mg/m3 (as CEILING) (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.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    The liquid defats the skin.

    ENVIRONMENTAL
    DATA
    This substance may be hazardous to the environment; special attention should be given to water and fish.
    NOTES
    The applying occupational exposure limit value should not be exceeded during any part of the working exposure. Also consult ICSC # 0344 (1,3,5-Trichlorobenzene).
