What could be a consequence of using improper filling techniques that allow static charge to build?

Using improper filling techniques that permit the buildup of static charge can significantly increase the risk of fire and explosion. When liquids, especially flammable or combustible materials, are transferred or filled improperly, they can generate static electricity due to friction and flow dynamics. If the accumulated static charge discharges, it can create a spark. In the presence of flammable vapors or residues, this spark could ignite fires or lead to explosive situations, which poses severe safety hazards in industrial settings.

Other choices reflect misleading outcomes of improper filling techniques. Increased efficiency, improved product quality, or no significant impact do not align with the serious hazards associated with static discharge risks. These incorrect perceptions may contribute to negligence in handling procedures, underestimating the potential for catastrophic incidents that can arise from improper practices.
