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.
