What is the first step when using the Thermal Containment Bag?

• A. Extinguish fire and cool device for at least 15 minutes
• B. Don Fire Proof Gloves
• C. Place device into TCB
• D. Pull red loop to remove strap and expose Velcro

Answer: (A)

The first step is to extinguish any fire and cool the device for at least 15 minutes. Stopping the blaze and bringing the temperature down reduces the immediate danger to you and prevents the heat from driving further damage or re-ignition as you begin containment. Once the device is no longer burning and has cooled, you would proceed with protective handling and containment steps—such as donning fireproof gloves if needed, placing the cooled device into the Thermal Containment Bag, and then using the bag’s closure (pulling the red loop to remove the strap and expose the Velcro) to seal it. The other steps are important for protection or proper sealing, but they come after the heat has been addressed.
