The correct answer is D) All of the above. All three methods can help reduce the possibility of producing an electrical spark during cargo transfer operations. Using a cargo hose with a built-in electrical bonding wire, connecting a bonding wire between the shore side piping and the vessel, and placing an insulating flange or non-conducting hose in the setup can all help prevent static electricity buildup and the potential for sparks, which could ignite flammable vapors. These methods are recommended and often required by regulations to ensure safe cargo transfer procedures on board vessels and at marine terminals.
