Bonding and grounding are primarily used to prevent which hazard?

• A. Static electricity buildup
• B. Direct short circuits
• C. Gas leaks
• D. Fire spread

Answer: (B)

Bonding and grounding are there to control electrical potential and give fault current a low-impedance path. This keeps conductive parts at the same electrical potential and ensures that if a fault occurs, the current can quickly flow to remove the fault, causing protective devices to trip and preventing dangerous arcing. That arcing is what can lead to ignition, equipment damage, or electric shock. So, the primary hazard these practices prevent is direct short circuits or the dangerous arcing that accompanies faults. Gas leaks and fire spread are addressed by other measures like gas detection, ventilation, and fire- control design, while static electricity buildup is a related but separate concern and not the main purpose of bonding and grounding.
