Cathodic protection by impressed current or galvanic methods are in common use for the protection of corrosion in steel structures such as pipes, tanks, wharves and bridges. Both methods of cathodic protection are electrical processes that involve voltages and currents being introduced into the structures. Occasionally these facilities are situated in hazardous locations involving explosive materials such as flammable gases, explosive dusts or petroleum-based liquids where there is a risk of explosion from sparks caused by electrical voltages and currents. This paper provides an overview of the relevant requirements for hazardous area installations of both impressed current and galvanic cathodic protection systems and provides two case studies of recent projects providing insight into the outcomes.
