Which of the following measures is NOT effective in reducing static buildup?

Increasing loading speed is not effective in reducing static buildup because it can actually exacerbate the problem. When loading liquids, a higher loading speed tends to generate more turbulence and agitation, which can result in an increased likelihood of static charge accumulation. This is especially true with non-conductive fluids, where rapid movement and splashing create friction, generating static electricity as the materials interact with each other and with container surfaces.

On the other hand, the other measures listed are effective in managing static buildup. Tank cushioning helps minimize the impact that liquid has on tank walls, reducing splashing and turbulence. The relaxation period allows any generated static charges to dissipate safely before transferring or handling the liquid. Reducing flow splashing decreases the chances of static generation by limiting the movement of liquid against surfaces that can create friction. Each of these methods focuses on promoting safer loading and handling conditions by controlling or reducing the factors that lead to static electricity.
