Potential health effects

ACUTE EFFECTS 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. Inhalation of high concentrations of powder, dust, or fume may cause respiratory and nasal irritation, coughing, and difficulty breathing. Inhalation of high concentrations of metallic copper dusts or fumes may cause nasal irritation and/or nausea, vomiting and stomach pain. Inhalation of high concentrations of beryllium dust can cause a condition known as berylliosis which is a form of chemically induced pneumonia causing fever, chest pain, coughing, fatigue, bloody sputum, wheezing and difficulty breathing. These symptoms may be delayed and not appear for up to 2 weeks after an acute high exposure. Ingestion: Ingestion of large amounts of dust may cause nausea, vomiting, constipation, cramps, and or stomach pain.

Potential chronic health

Prolonged or repeated skin contact with dust may cause more severe irritation or dermatitis. Prolonged or repeated inhalation of dust or fume may cause more severe irritation and possibly lung damage. Repeated exposure may cause an allergic skin reaction consisting of itching, redness, swelling, and rash or urticaria (hives) in sensitized individuals. Chronic exposure to very high concentrations of manganese dust has caused nervous system effects including muscle weakness, tremors, and behavioral changes. Epidemiological studies in humans have shown an association between lung and nasal cancers and prolonged occupational exposures to high concentrations of nickel. Prolonged, repeated exposures to beryllium can cause a chronic lung disease characterized by coughing, wheezing and reduced capacity of the lungs which can lead to heart failure.

Medical Conditions Generally Aggravated by Exposure

Exposure to dust or fume may aggravate an existing dermatitis or neurological condition, asthma, emphysema, or other respiratory disease.
