Surface engineering refers to a wide range of technologies designed to modify the surface properties of metallic and non-metallic components for decorative and/or functional purposes.
Some surface engineering sites hold significant quantities of substances and preparations that are toxic. These include cyanides, dichromate and chromium trioxide. These may be held as raw materials, in tank or as waste.
Use of some of these substances can lead to lung damage such as work-related asthma from the use of 2-pack (isocyanate) paints.
Isocyanate (typically in 2-pack paints) is the most common cause of occupational asthma. It also causes dermatitis. It affects workers spraying 2-pack (2 k) isocyanate paints in industries like engineering and motor vehicle repair.
Risks to health can be greatly reduced where exposures to fumes and airborne chemicals is controlled.
