Which practice best reduces the risk of accidental ignition during ground handling?

• A. Use a safe arming/disarming protocol.
• B. Keep wires exposed to monitor voltages.
• C. Work in a cluttered space to maximize efficiency.
• D. Ignore safety protocols and rush to launch.

Answer: (B)

The situation tests the idea that knowing the electrical state of the system in real time lowers ignition risk during ground handling. When you have wires exposed for voltage monitoring, you can directly observe whether circuits are truly de-energized and spot any unexpected voltage or insulation fault before you touch anything. This visibility helps you avoid arcs, heat, or sparks that could ignite flammable propellants or vapors in the area. In practice, voltage monitoring points let the crew verify a safe electrical condition before handling components, so you’re actively preventing an energy source from becoming a ignition trigger. Other options would promote unsafe conditions or fail to provide this immediate safety check, making ignition hazards more likely.
