Question 1 of 27070

To minimize the possibility of an explosion caused by the discharge of static electricity, the vessel should __________.

🔍 Key Concepts

• Static electricity and bonding/grounding on tankers and during cargo transfer • Difference between bonding to ship structure and grounding to shore • Why ignition sources (lamps, flashlights, flame safety lamps) are controlled in vapor-filled or enclosed spaces

💭 Think About

• Which option directly reduces the buildup and discharge of static electricity between the ship and the cargo/shore system, rather than just changing the type of light used? • Is it safer for the ship’s electrical system to be tied into shore’s ground, or for the ship’s own systems and piping to be at the same potential? • Think about standard tanker cargo-handling procedures: what is the usual practice with bonding/grounding before connecting or disconnecting cargo hoses?

✅ Before You Answer

• Verify which method addresses equalizing electrical potential between components in the cargo transfer system. • Check whether connecting a vessel’s structure to shore ground is considered standard practice or a hazard in petroleum transfer operations. • Confirm which options actually remove or reduce static discharge risk, versus only addressing lighting or ignition sources in confined spaces.
