Comments

Harmful if swallowed; [MSDSonline] Acute copper poisoning after ingestion can cause liver injury, methemoglobinemia, and hemolytic anemia. Acute renal failure may result, secondary to massive hemoglobinuria. [Goldfrank, p. 1259] Classified as category I for skin and eye irritation (corrosive); Category II for acute oral and dermal exposure (moderate toxicity); Category III for acute inhalation exposure (low toxicity); Positive results in dermal sensitization studies; [Reference #2] May cause irritation; Harmful by ingestion; [Alfa Aesar MSDS] See "Copper."
