Why must batteries be disconnected before structural repairs?

Why must batteries be disconnected before structural repairs?

• A. To improve battery life during repairs.
• B. To avoid tripping the circuit breaker unrelated to repairs.
• C. To comply with insurance requirements.
• D. Electrical damage or accidental airbag deployment.

Answer: (D)

The main idea is to prevent unintended airbag deployment and protect the electrical system during repairs. Airbags and their control module are designed to fire in response to specific electrical signals and sensor inputs. When you’re cutting, grinding, or moving panels, wiring and connectors can be disturbed, creating shorts or stray voltages that could trigger deployment or damage sensitive electronics. By disconnecting the battery, you remove power from the airbag system, eliminating the energy source that could cause an unexpected actuation and protecting components from electrical damage. It’s not primarily about preserving battery life, avoiding a circuit breaker, or meeting insurance paperwork—safety and preventing accidental deployment are the driving reasons.
