            INHALATION 
            (see Ingestion). 
            Local exhaust or breathing protection. 
            Fresh air, rest (see Notes). Refer for medical attention. 

            SKIN 
            MAY BE ABSORBED! Redness. Roughness. Yellow staining of the skin 
            (further see Inhalation). 
            Protective gloves. Protective clothing. 
            Remove contaminated clothes. Rinse skin with plenty of water or 
            shower. Refer for medical attention. 

            EYES 

            Safety goggles. 
            First rinse with plenty of water for several minutes (remove contact 
            lenses if easily possible), then take to a doctor. 

            INGESTION 
            Nausea. Vomiting. Palpitations. Collapse. Sweating. 
            Do not eat, drink, or smoke during work. 
            Rest. Refer for medical attention. 

            SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING 
            Evacuate danger area! Do not allow to dry out. Sweep spilled 
            substance into containers. Wipe up remainder in sand or other inert 
            material, then remove to safe place (extra personal protection: 
            complete protective clothing including self-contained breathing 
            apparatus). 
            Fireproof. Separated from combustible and reducing substances, food 
            and feedstuffs. Cool. 
            Unbreakable packaging; put breakable packaging into closed 
            unbreakable container. Do not transport with food and feedstuffs.

                  PHYSICAL STATE; APPEARANCE:
                  YELLOW CRYSTALS (SEE NOTES). 

                  PHYSICAL DANGERS:
                  Dust explosion possible if in powder or granular form, mixed 
                  with air. 

                  CHEMICAL DANGERS:
                  May explosively decompose on shock, friction, or concussion. 
                  May explode on heating. Shock-sensitive compounds are formed 
                  with alkalis, ammonia and most metals. The substance 
                  decomposes on heating producing toxic gases including nitrogen 
                  oxides (see Notes). 

                  OCCUPATIONAL EXPOSURE LIMITS (OELs):
                  TLV not established. 


                  ROUTES OF EXPOSURE:
                  The substance can be absorbed into the body by inhalation, 
                  through the skin and 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 may cause effects on metabolism , resulting in 
                  very high body temperature. Exposure may result in death. 

                  EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
                  Repeated or prolonged contact with skin may cause dermatitis. 
                  The substance may have effects on the peripheral nervous 
                  system. The substance may have effects on the eyes , resulting 
                  in cataracts.

            ENVIRONMENTAL
            DATA
            This substance may be hazardous to the environment; special 
            attention should be given to water organisms. 

            N O T E S 
            Use all available methods for reducing body temperature. Because of 
            its explosive properties, the compound is used in the form of a 
            water paste. UN 0076 applies to the dry compound. CAS 25550-58-7 
            applies to unspecified isomers of dinitrophenol. Transport
