Proper bonding of two containers together minimizes the possibility of static spark near flammable vapor. Which action is described?

• A. Bonding
• B. Grounding
• C. Ventilation
• D. Insulating

Answer: (A)

Equalizing electrical potential between two conductive containers prevents a spark when flammable vapors are present. Bonding creates a conductive path between the containers so charges can flow freely and reach the same voltage, eliminating a potential difference that could jump as a spark during transfer or movement of liquids. Grounding would drain charge to the earth, which helps, but the action described focuses on making the two containers have the same potential rather than directing charge away to ground. Ventilation reduces vapor buildup but doesn’t address static discharge between containers, and insulating would keep charges from moving, which can maintain or worsen a dangerous potential difference.
