    PHYSICAL STATE; APPEARANCE:
     COMPRESSED LIQUEFIED GAS , WITH CHARACTERISTIC ODOUR.




    CHEMICAL DANGERS:
     On contact with hot surfaces or flames this substance decomposes forming toxic and corrosive fumes.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established.
    MAK not established.


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation.

    INHALATION RISK:
     A harmful concentration of this gas in the air will be reached very quickly on loss of containment.

    EFFECTS OF SHORT-TERM EXPOSURE:
     Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the central nervous system, cardiovascular system , resulting in cardiac disorders.
