Which step is included in handling a PED Lithium Battery incident?

• A. Remove any external electrical power from the device
• B. Leave device powered
• C. Do not log anything
• D. Ignore incident

Answer: (A)

Removing external electrical power from the device is the step that cuts off the energy feeding the battery, which is crucial in a PED lithium battery incident. When a lithium battery is stressed or damaged, continuing to power the device from a charger or other external source can keep the battery heating and may worsen a thermal runaway or ignition. Unplugging or disconnecting the power source reduces heat generation and gives responders a safer, clearer situation to manage.

Leaving the device powered keeps energy flowing into the battery, maintaining the risk of further heating or ignition, so it’s not the safer option. Not logging anything or ignoring the incident avoids proper reporting and follow-up, which are necessary parts of handling such incidents.
