What term describes the metal connection used to equalize electrical potential between containers during the transfer of flammable liquids?

• A. Bonding wire
• B. Grounding strap
• C. Insulating sleeve
• D. Jumper cable

Answer: (A)

During the transfer of flammable liquids, static charges can build up and cause a spark if the containers are at different electrical potentials. To prevent that risk, a conductive link is placed between the containers so they share the same potential. This is bonding, and the conductor used is a bonding wire. The purpose is to create a low-resistance path that equalizes potential between the vessels, not to discharge to the earth. Grounding would involve connecting to the earth and is a different concept; insulating sleeves prevent conduction; jumper cables are generic battery connections, not the specific bonding method for liquid transfer.
