Ingestion : Very large doses can cause vomiting, diarrhea, and prostration. Dehydration and congestion occur in most internal organs. Hypertonic salt solutions can produce violent inflammatory reactions in the gastrointestinal tract.
Skin Contact : May irritate damaged skin; absorption can occur with effects similar to those via ingestion.
Eye Contact : Causes irritation, redness, and pain. (For salt concentrations greater than the normal saline present.)
