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
Eye Contact: May cause moderate to severe irritation of the eyes.
Skin Contact: May cause moderate to severe irritation of the skin.
