Abstract

For a compound to be classified as a volatile corrosion inhibitor (VCI), it must possess two basic properties: volatility and ability of the vapour to retard the corrosion rate. VCIs can be used in cases where other protection methods are not feasible or when protection could be very expensive. Usually, most organic compounds giving inhibitive action against corrosion of metals have one or more electronegative atoms (e.g. oxygen, nitrogen, sulphur) in the form of functional groups and/or have an unsaturated bond. Inhibitors for atmospheric corrosion can be used economically only in enclosed spaces. When metal items are in transit, the following protection methods should be considered: protective oils, water or oil based formulations and/or protective packaging. In the manufacture and use of corrosion inhibitors and their products (e.g. VCI paper), workers are occupationally exposed to various chemicals, noise and elevated air temperatures. The concentrations of chemicals in workplace air are dependent on the manufacturing process and equipment used. It is recommended that any plant processing VCIs should have good processing equipment and ventilation. Workers should wear protective clothing, safety glasses and gloves when handling VCI products.
