Section 3: Hazards Identification
   Dust may be irritating to eyes and respiratory tract. Ingestion of large amounts of soluble borates may cause
   Emergency Overview:
   toxic effects.
   Primary Routes of Exposure:       Ingestion, Inhalation of dust.    
   Eye Contact:       May cause mild to moderate irritation of the eyes    
   Skin Contact:       May cause slight to mild irritation of intact skin. Irritation is greater if broken skin is exposed.    
   Inhalation:       Dust may be irritating to the nose, mucous membranes and respiratory tract.    
   Soluble borates, if ingested in large quantity, may cause twitching of facial muscles, diarrhea, kidney damage,
   Ingestion:
   shock and coma.
   Acute Health Affects:       May be irritating to broken skin, eyes and respiratory tract.    
   Repeated exposure to small amounts has not been associated with long term chronic effects. Large repeated
