Transport facilities and wastewater treatment plants are experiencing increased concentrations in air pollutants emitted from sewage and which is diffused into the air. The wastewater pollutants have an acute smell and create problems for workers at the plant and residents of adjacent areas.

Chlorine, which is a very toxic gas, is stored in various water treatment facilities such as swimming pools, thermal spas, spas etc. The possible leakage of chlorine into the atmosphere creates problems over a wide area from the source of the leak. Risk management of such cases includes amongst other means the installation of emergency systems for the immediate treatment of the leakage.

Corrosion can affect integrated circuits, electronic circuit boards, control relays, transformers, motor control systems, control device systems and finally every type of electrical or electronic equipment. This corrosive effect develops mainly in certain parts which are particularly sensitive: terminals, contacts, IC connectors, windings and electrical systems.
