Physical hazards

System (HMIS) None National Fire (NFPA) Protection Association Mixture. Not rated. HUMAN THRESHOLD RESPONSE DATA (IDLH) Value(s): for nickel and silver is 10 mg/m. The IDLH for cobalt is 20 mg/m. The IDLH for copper, lead and tin is 100 mg/m’. The IDLH for chromium is 250 mg/m°.

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 severe 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. The metal fume may also produce influenza-like symptoms, known as metal fume fever. Symptoms of this reaction may include metallic taste, runny nose, nausea, fever and chills. These effects usually disappear within 24 hours, but may be delayed in onset. Exposure to high concentrations of chromium dusts or fumes can cause severe respiratory and nasal irritation. Ingestion Ingestion of large amounts of dust may cause nausea, diarrhea 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. Chronic exposure to dust or fume may also lead to the development of permanent, severe, obstructive or fibrotic lung disease characterized by coughing, wheezing, and shortness of breath. Repeated exposure may cause an allergic skin reaction consisting of itching, redness, swelling, and rash or urticaria (hives) in sensitized individuals. 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. Ingestion of large amounts of cobalt may affect the heart, but this type of exposure is not anticipated under normal occupational conditions. Prolonged or repeated exposures to chromium dusts or fumes may cause perforation of the nasal septum, bloody nose and other symptoms of severe nasal irritation. Epidemiological studies in humans have shown an association between lung and nasal cancers and prolonged occupational exposures to high concentrations of nickel. 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. Long-term exposure to silver at high concentrations can produce a condition called argyria, which is a bluish-gray pigmentation of the skin and other body tissues. This effect is not known to be associated with any toxic effects.

Medical Conditions Generally Aggravated by Exposure

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