Which option is NOT part of the official Thermal Containment Bag usage steps?

• A. Use the bag to extinguish directly without device
• B. Pour water into bag through Velcro closure
• C. Don Fire Proof Gloves
• D. Place device into TCB

Answer: (A)

The key idea is using the Thermal Containment Bag to safely manage a thermal event by containing the device and cooling it from within. Donning fireproof gloves protects you from the extreme heat as you handle the hot device. Placing the device into the bag seals it off from the cabin and crew, helping to contain heat and any fumes. Pouring water into the bag through the Velcro closure provides controlled cooling to prevent reignition and further heat buildup inside the containment. Using the bag to extinguish directly without the device is not part of the official steps because the bag’s purpose is containment and cooling from within, not acting as a stand-alone extinguisher on the fire.
