A grounding wire minimizes the risk of ignition by discharging which of the following?

• A. discharges the static charge
• B. increases the static charge
• C. neutralizes the ignition source
• D. reduces air flow

Answer: (A)

Discharging the static charge is what reduces ignition risk. Grounding provides a direct, low-resistance path for static electricity to flow to the earth, so any buildup on people, equipment, or surfaces is released rather than allowed to accumulate. When this charge is kept near zero, the chance of a spark forming in a flammable environment drops significantly, lowering the risk of ignition. The other ideas don’t fit because increasing static charge would raise ignition risk, not reduce it; grounding doesn’t neutralize an ignition source like heat or flame—it's about eliminating static buildup; and reducing air flow isn’t a function of grounding and doesn’t address the static discharge mechanism.
