EXPOSURE
PREVENT GENERATION OF MISTS! STRICT HYGIENE!

  • INHALATION
    		• Abdominal cramps. Cough. Diarrhoea. Laboured breathing. Nausea. Sore throat. Vomiting. Symptoms may be delayed (see Notes).
    		Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest. Half-upright position. Refer for medical attention.
  • SKIN
    		• MAY BE ABSORBED! Redness. After delay skin burns.
    		Protective gloves. Protective clothing.
    		Rinse and then wash skin with water and soap. Refer for medical attention.
  • EYES
    		• Redness. Pain.
    		Safety spectacles, 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 cramps. Diarrhoea. Nausea. Vomiting.
    		Do not eat, drink, or smoke during work. Wash hands before eating.
    		Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give plenty of water to drink. Refer for medical attention.

    PHYSICAL STATE; APPEARANCE:
     LIQUID.




    CHEMICAL DANGERS:
     The substance decomposes on burning producing toxic fumes.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV (as tin): ppm; 0.1 mg/m3 A4, STEL 0.2 mg/m3 A4 (skin) (ACGIH 1997).


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

    INHALATION RISK:
     Evaporation at 20░C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance irritates severely the eyes, the skin. Inhalation of the aerosol may cause lung oedema (see Notes). The substance may cause effects on the thymus , resulting in depression of the immune function.


    PHYSICAL
    PROPERTIES
    Boiling point: 173░C
    Melting point: <45░C
    Relative density (water = 1): 1.17 at 20░C
    Solubility in water: poor
    		Vapour pressure, Pa at 20░C: 0.001
    Flash point: 190░C c.c.
    Octanol/water partition coefficient as log Pow: 3.19
    ENVIRONMENTAL
    DATA
         		The substance is very toxic to aquatic organisms. In the food chain important to humans, bioaccumulation takes place, specifically in fish and molluscs. Avoid release to the environment in circumstances different to normal use.
    N O T E S
    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 is therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered.
