Potential health effects

ACCUTE EFFCTS Eye Dust or fume can cause irritation consisting of redness, swelling, and pain. May cause conjunctivitis with repeated exposures. Skin Material not expected to be absorbed through the skin. Contact with dust may cause mild irritation consisting of redness and/or swelling. Inhalation Harmful if inhaled.

Prolonged or repeated inhalation of dust or fume may cause an allergic type of asthma reaction characterized by wheezing, coughing, and extreme breathing difficulty in sensitized individuals. Chronic exposure to lead can cause kidney damage, anemia, reproductive effects, developmental effects and permanent nervous system damage in humans including changes in cognitive function. Epidemiological studies in humans have shown an association between lung and nasal cancers and prolonged occupational exposures to high concentrations of nickel. Epidemiological studies in humans have shown an association between increased incidences of lung and skin cancer and prolonged exposures to high concentrations of arsenic. Arsenic is classified as a known human carcinogen.
