Which of the following is a statement about bonding during transfers of flammable liquids?

• A. Ground and bond the transfer equipment.
• B. Ensure ventilation is present during transfer.
• C. Use only non-metallic transfer hoses.
• D. Purge the container continuously during transfer.

Answer: (B)

Controlling vapors during transfers is essential. Ventilation helps keep flammable vapors from reaching concentrations that could ignite if there’s any ignition source, including static discharges. Even when bonding and grounding are used to prevent static electricity, without adequate ventilation vapors can accumulate and create a dangerous environment. So, the statement about ensuring ventilation during transfer addresses the key safety measure of reducing vapor buildup, which is why it’s considered the best choice here. The other options relate to bonding or equipment choices, but they don’t address the vapor-control aspect as directly.
