The substance is irritating to the eyes and respiratory tract. Inhalation of fumes may cause metal fume fever. Ingestion could cause effects on the kidneys and liver. The effects may be delayed. Copper itself does not burn. The finely divided Copper powder may burn in the air or become an explosion hazard. POISONOUS GASES ARE PRODUCED IN FIRE, including Copper fumes and Copper Oxides. Use water spray to keep fire-exposed containers cool. The primary metals of concern in terms of galvanic corrosion contact with Copper are aluminium and zinc. Large differences in the thermal expansion rate between Copper and these metals may cause additional problems. Also, avoid using Copper and some brass fasteners with aluminium, zinc and most ferrous metal.
When heated, CuO decomposes to release oxygen and serves as an oxidizer in reactive composites and chemical looping combustion. Other instruments have shown either one or two decomposition steps during heating. We have confirmed that CuO decomposes at slower and higher heating rates in two steps. The thin layer of copper oxide is a protective cover which protects Copper from further oxidation. Thus, this copper oxide does not burn as it already reacts with the air's oxygen. CuO primarily uses copper salts and compounds, but it finds use in other applications, such as pottery glazes, to produce blue, green or red colours. Its use in fireworks and pyrotechnics produces a moderate blue colour when used with chlorates and other chlorinated oxidizers such as perchlorates. Copper is one of a few metallic elements with a natural colour other than grey or silver. Pure Copper is orange-red and acquires a reddish tarnish when exposed to air.
