Remove contaminated clothing and shoes immediately. Get medical attention immediately. Contact with oxalate salts may cause severe irritation with redness and swelling of the mucous membranes and possibly burns. Get medical attention immediately. Ingestion of oxalates may cause severe internal pain followed by collapse.
Oxalates combine with serum calcium to form insoluble calcium oxalate.
The reduction of available calcium leads to violent muscular stimulation with convulsions, and collapse. Calcium oxalate crystals can form in renal tubules and other tissues. The kidneys may show cloudy swelling, hyaline degeneration and scerosis of the tubules. Acute renal failure may occur due to blockage of renal tubules by calcium oxalate which may cause death. Symptom may appear almost immediately, and death may occur within a few minutes apparently as a result of severe gastricenteritis and secondary shock.
