Bonding during transfer of flammable liquids is intended to prevent which hazard?

• A. Static electricity
• B. Electrical shock
• C. Chemical reaction
• D. Temperature change

Answer: (A)

The main concept here is preventing ignition from static electricity during the transfer of flammable liquids. As liquid moves or flows, it can build up static charge due to friction and separation of molecules. If the source and receiving vessels have different electrical potentials, a spark could be emitted when they are connected or disconnected, igniting flammable vapors. Bonding creates a direct conductive path between the equipment so both vessels reach the same electrical potential, eliminating the spark risk. This specifically targets static electricity as the ignition source, not electrical shock, chemical reactions, or temperature changes.
