Electrocution: Using electrical equipment, fixed installations and/or portable equipment, especially in the wet conditions associated with shrimp farming, entails the risk of electrocution, electric shock (including dislocation of bones due to violent body reaction from electric shock), and burns. Workers on shrimp farms are exposed to mains voltage (220 volts) and 3 phase industrial voltages (380 volts plus). Electrical devices typically used in aquaculture include water pumps for filling and emptying ponds, aerators to keep pond water oxygenated, lighting installations, and portable equipment and cables
