Principle Routes of Exposure

Eyes, inhalation, ingestion Signs and Symptoms of Overexposure: Prolonged inhalation of cobalt dust, fumes or mist may cause serious respiratory illness. There are references in literature associating cobalt with interstitial fibrosis, a disease that can be fatal. Eyes: May cause irritation. Skin: May cause irritation. Single prolonged contact is essentially non-irritating. Repeated exposure may cause allergic dermatitis, usually occurring in the skin areas of friction. May cause cross-sensitivity to Chromium and Nickel. Ingestion: Amounts of ingested incidental to industrial handling are not likely to cause injury. Single dose oral toxicity is low. Ingestion of significant amounts of cobalt has been reported to have potential for causing blood, heart, thyroid and pancreatic damage. Inhalation: Inhalation may cause an irritation of the respiratory organs of sensitive persons resulting in obstruction of airways. Chronic Exposure: Prolonged inhalation of cobalt dust, fumes or mist may cause serious respiratory illness. Chemical Listed as Carcinogen or Potential Carcinogen: Classified A3 (Proven for animal.) by ACGIH. Cobalt is an OSHA Select carcinogen. NTP Report on Carcinogens lists only cobalt sulfate as "Reasonably anticipated to be a human carcinogen". See Toxicological Information (Section 11)
