Effects of Overexposure                                                  
  INHALATION:  Major potential route of exposure.  Minimal effects have  
			observed at levels below 1000 ppm.  Dizziness, drowsiness,
			and throat irritation possible at levels above 1000 ppm.  
			Unconsciousness and death at levels above 10,000 ppm.     
			Blood pressure depression, cardiac sensitization, and     
			ventricular arrhythmia can result from exposure to near-  
			anesthetic levels.                                        
                                                                         
  EYES:  Liquid can cause slight, temporary irritation with slight,      
	    temporary corneal injury.  Vapors can irritate eyes.            
                                                                         
  SKIN:  Prolonged or repeated contact with liquid can cause freezing of 
	    skin tissue, defatting, and dermatitis.                         
                                                                         
                                                                         
  INGESTION:  Single-dose toxicity is low to moderate.  If vomiting      
		    should occur, the liquid can be aspirated into the lungs,  
		    which can cause chemical pneumonia and systemic effects.   
		    Human psychotropic, gastrointestinal, and central nervous  
		    system effects possible.                                   
                                                                         
                                                                         
-------------------------------------------------------------------------
Emergency and First Aid Procedures                                       
  INHALATION:  Remove to fresh air.  If breathing has stopped, administer
               artificial respiration.  Seek medical attention.          
                                                                         
  EYES:  Flush eyes for at least fifteen minutes with clear water.  If   
         irritation persists, seek medical attention.                    
                                                                         
  SKIN:  Wash with soap and water.  For frostbite, seek immediate medical
         attention.                                                      
                                                                         
  INGESTION:  DO NOT INDUCE VOMITING!  Give 2 glasses of water and       
		    immediately seek medical attention.
