What is the purpose of bonding during transfer?

• A. To improve foam quality.
• B. To accelerate transfer rate.
• C. To eliminate static electricity buildup and reduce the risk of sparks or ignition during transfer.
• D. To reduce water consumption.

Answer: (C)

When transferring flammable liquids, static electricity can build up on the moving liquid and the containers, creating a risk of a spark that could ignite vapors. Bonding connects the source and receiving vessels with a conductive path, equalizing their electrical potentials so charges don’t build up and discharge as a spark. This directly reduces the ignition risk during transfer, making it the main safety purpose of bonding. The other options relate to foam quality, transfer speed, or water use, none of which are addressed by bonding.
