            FIRE FIGHTING 
            FIRE Not combustible but forms flammable gas on contact with water 
            or damp air. Highly flammable when finely divided. Forms flammable 
            gas on contact with water or damp air. Many reactions may cause fire 
            or explosion. 
            NO open flames, NO sparks, and NO smoking. NO contact with water and 
            incompatible substances (see Chemical Dangers). 
            Special powder, dry sand, NO other agents. NO water. 

            EXPLOSION Risk of fire and explosion on contact with water and 
            incompatible substances (see Chemical Dangers). 

            In case of fire: cool drums, etc., by spraying with water but avoid 
            contact of the substance with water. 


            EXPOSURE 
            PREVENT DISPERSION OF DUST! 


            INHALATION 

            Avoid inhalation of fine dust and mist. 
            Fresh air, rest. Refer for medical attention. 

            SKIN 

            Protective gloves. 
            Remove contaminated clothes. Rinse skin with plenty of water or 
            shower. Refer for medical attention. 

            EYES 
            Redness. Pain. 
            Safety goggles. 
            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. 
            Refer for medical attention. 

            SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING 
            Remove all ignition sources. Sweep spilled substance into 
            containers. Do NOT wash away into sewer. Carefully collect 
            remainder, then remove to safe place. Do NOT absorb in saw-dust or 
            other combustible absorbents (extra personal protection: complete 
            protective clothing including self-contained breathing apparatus). 
            Fireproof. Separated from incompatible substances (see Chemical 
            Dangers). Dry. Keep under inert gas. Keep under petroleum oil. 
            Airtight. Unbreakable packaging; put breakable packaging into closed 
            unbreakable container.
