TLV Permissible exposure limits have not been established for this product. Toxicity for animals Chronic effects on humans Acute oral toxicity (LD50): 30000 mg/kg [Rat]. (IRON) CARGINOGENIC EFFECTS: Not available MUTAGENIC EFFECTS: Not available. TERATOGENIC EFFECTS: Not available. DEVELOPMENTAL TOXICITY: Not available. There are no chronic effects if used in its purchased form; however, if product is used in a manner that generates fumes, long term (chronic) overexposure to iron oxide fumes can lead to siderosis (iron deposits in lung). Siderosis will clear in time, when exposure to iron and its compounds ceases. Acute effects on humans Abrasive to eyes and skin.
