In terms of electrical safety, why is static control important during the refueling process?

Static control is essential during the refueling process primarily to prevent the ignition of flammable vapors. When fuel is pumped or transferred, friction and movement can generate static electricity. If sufficient static charge builds up, it can discharge, leading to sparks that might ignite any flammable vapors present in the vicinity. This is particularly critical because fuel vapors are often heavier than air and can accumulate, creating an explosive atmosphere. Implementing static control measures, such as grounding and bonding equipment, effectively dissipates any electrostatic charges, significantly reducing the risk of ignition and thus enhancing safety during refueling operations.

While other options may touch on various aspects of fuel management, they do not address the primary safety concern of preventing fire hazards which is the fundamental purpose of static control in this context.
