What is the purpose of bonding and grounding pumps and hoses during operations?

The correct answer addresses the critical safety measure of bonding and grounding in operations involving pumps and hoses, particularly when dealing with flammable materials such as heating oil. The purpose of bonding and grounding is to provide a pathway for static electricity to discharge safely. During the transfer of fluids, especially in environments where volatile substances are present, static electricity can accumulate due to the movement of the liquid through hoses and pipes. If this static discharge occurs in the presence of flammable vapors, it can lead to ignition and potential fire hazards.

By bonding the pump and hose, operators connect them electrically, reducing the risk of electrical charge buildup. Grounding ensures that any static electricity that does build up is directed away from the equipment and the surrounding environment, further enhancing safety. This practice is essential not only for meeting safety regulations but also for protecting equipment and personnel involved in the transfer process. Thus, the bonding and grounding of pumps and hoses serve a vital function in preventing static electricity buildup, making it the correct reason for their implementation during operations.
