            EXPLOSION 




            EXPOSURE 
            PREVENT DISPERSION OF DUST! 


            INHALATION 
            Cough. Sore throat. 
            Local exhaust or breathing protection. 
            Fresh air, rest. 

            SKIN 
            Redness. 
            Protective gloves. Protective clothing. 
            Remove contaminated clothes. Rinse skin with plenty of water or 
            shower. 

            EYES 
            Redness. 
            Safety spectacles. 
            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. 


            SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING 
            Sweep spilled substance into containers; if appropriate, moisten 
            first to prevent dusting (extra personal protection: P2 filter 
            respirator for harmful particles).

                  PHYSICAL STATE; APPEARANCE:
                  PALE YELLOW CRYSTALLINE SOLID. 

                  PHYSICAL DANGERS:





                  OCCUPATIONAL EXPOSURE LIMITS (OELs):
                  TLV not established. 


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

                  INHALATION RISK:
                  Evaporation at 20°C is negligible; a nuisance-causing 
                  concentration of airborne particles can, however, be reached 
                  quickly. 

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

                  EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
                  Repeated or prolonged contact may cause skin sensitization. 

            PHYSICAL
            PROPERTIES
                  Decomposes below melting point at 241°C
                  Solubility in water: soluble


            ENVIRONMENTAL
            DATA


            N O T E S 
            The substance reddens at 125°C and swells at 139°C.
