EXPOSURE
STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
  • INHALATION
    		• Cough. Laboured breathing. Shortness of breath. Sore throat. Symptoms may be delayed (see Notes).
    		Local exhaust or breathing protection.
    		Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.
  • SKIN

    		• Protective gloves.
    		Remove contaminated clothes. Rinse skin with plenty of water or shower.
  • EYES
    		• Redness. Pain.
    		Safety spectacles, 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

    		• Do not eat, drink, or smoke during work.
    		Rinse mouth.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment (extra personal protection: P3 filter respirator for toxic particles).
    		Separated from strong oxidants. Keep in a well-ventilated room.

    PHYSICAL STATE; APPEARANCE:
     WHITE TO YELLOW CRYSTALS OR POWDER , WITH CHARACTERISTIC ODOUR.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating and on burning producing toxic and corrosive fumes. Reacts with oxidants.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established.


    		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 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. Inhalation of the aerosol may cause lung oedema (see Notes). Medical observation is indicated.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     The substance may have effects on the liver, kidneys, nasal passage and thyroid gland , resulting in impaired functions or tissue lesions.
    PHYSICAL
    PROPERTIES
    Boiling point: 208°C
    Melting point: 63°C
    Solubility in water: none
    Vapour pressure, kPa at 78°C: 1.33
    		 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.0
    Flash point: 107°C
    Octanol/water partition coefficient as log Pow: 4.15
    ENVIRONMENTAL
    DATA
         		This substance may be hazardous to the environment; special attention should be given to fish. In the food chain important to humans, bioaccumulation takes place, specifically in aquatic organisms.
    N O T E S
    Toxicology is based on 1,2,4-trichlorobenzene. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered.
