Principle Routes of Exposure

Inhalation? Yes Eye Contact? Yes Skin Contact? Yes Ingestion? Yes Inhalation: Exposure to this product may cause irritation to the nose, throat and other respiratory areas. Prolonged exposure may cause silicosis, disabling and potential fatal lung diseases. Silicosis usually develops gradually over 20 years of exposure. The early symptoms of silicosis are not specific so the development of illness may not be detected until its advanced stages. Evidence of silicosis can normally be seen on an X-ray. Eye Contact: Exposure to airborne dust may cause immediate or delayed irritation or inflammation. Powder of splashes of wet product may cause effects ranging from moderate eye irritation to chemical burns and blindness. Skin Contact: Exposure to dry product may cause drying of the skin with consequent mild irritation. Dry product contacting wet skin or exposure to wet product may cause from moderate damage to severe skin burns. Effects can be delayed until hours after the exposure has ended. Some individuals may exhibit a sensitisation/allergic response possibly due to trace amounts of chromium (VI). That may appear in a variety of forms ranging from a mild rush to severe skin ulcers. Ingestion: Internal discomfort or ill effects are possible. CARCINOGENICITY: Crystalline silica is classified by the IARC and NTP as a known human carcinogen and considered to be a carcinogen by the state of California (Preposition 65). Inorganic cobalt compounds cause cancer in experimental animals and are classified as A3 by ACGIH. Chromium oxides are on IARC Group 3 and ACGIH A4 lists of carcinogens. Chromium (III) oxide is not classified as a human carcinogen by ACGIH and by IARC. MEDICAL CONDITIONS WHICH MAY BE AGGRAVATED BY INHALATION OR DERMAL EXPOSURE: Pre-existing upper respiratory and lung diseases.
