Section 3: Hazards Identification
   Soluble oxalates are harmful if swallowed. They precipitate calcium from the bloodstream causing violent
   Emergency Overview:
   muscular stimulation, convulsions, collapse, and death.
   Primary Routes of Exposure:       Ingestion, Inhalation of dust.    
   Eye Contact:       May cause moderate to severe irritation of the eyes.    
   Skin Contact:       May cause moderate to severe irritation of the skin.
