The Bag is designed to be used as a precautionary measure. If a (PED) Personal Electronic Device or other device shows signs of catching on fire such as higher than normally experienced heat coming off of the device, an electrical burning smell, smoke, etc. The user of the EFCS would dawn the provided thermal-guard gloves and any other optional personal protective equipment place the item in question inside of the EFCS , seal it closed and arm the suppression system by removing the arming pin. If the item in question has already caught on fire it is the discretion of the user of the EFCS to determine the safest practice to get the device inside of the bag. It may be necessary to use other means to extinguish the fire prior to picking up the device depending on how far the fire has escalated. As always it is best practices to move all unnecessary personnel and possible ignition sources away from the device to avoid injuries.
The suppression system is charged with an FAA recommended aqueous agent referred to as Cold Fire A.S.
