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.
Inhalation: Dust may be severely irritating to the nose, mucous membranes and respiratory tract.
Ingestion: Ingestion may cause vomiting, pain, violent muscular stimulation, convulsions, collapse, and death.
Soluble oxalates remove calcium from the bloodstream. This interferes with the central nervous system
Acute Health Affects:
causing violent convulsions and death. Large amounts of copper salts are toxic when ingested.
Prolonged exposure to oxalates can lead to kidney failure resulting from calcium oxalate precipitation in renal
