What action should you take if you hear crackling from a PED Lithium Battery?

• A. Extinguish flames and drizzle water over PED
• B. Do nothing
• C. Move device to rear galley
• D. Deactivate the device

Answer: (A)

Hearing crackling from a PED lithium battery signals a potential fire risk due to thermal runaway, where the cell overheats and can ignite. The best action is to extinguish any flames and dribble water over the device to cool it down. Water works as a heat sink, absorbing the heat from the burning or hot cells and helping to prevent propagation to other cells, which reduces the chance of reignition and spreads of smoke or gases. This direct cooling and suppression of the flame address the hazard at its source. Doing nothing leaves the fire to grow, which can rapidly become more dangerous. Simply moving the device to another location does not extinguish the fire or cool the battery, and could spread smoke or heat to other areas. Deactivating the device might stop the current, but it does not remove the heat or extinguish active flames, so the risk remains.
