How long does a Walter Kiddie Fire Extinguisher typically last when in use?

The duration of a Walter Kiddie Fire Extinguisher in use is typically around 8 to 15 seconds. This timeframe is essential for flight attendants to understand as it dictates how quickly they need to act in an emergency situation. During those crucial seconds, the user must aim the extinguisher at the base of the fire and use sweeping motions to maximize effectiveness. Knowing that these extinguishers only provide a limited discharge time reinforces the importance of swift and decisive action when using the equipment against a fire. Additionally, it emphasizes the need for training and practice to ensure that all personnel are familiar with the device's operation and can react appropriately under stress.

In contrast, durations outside the 8 to 15 second range do not align with the operational characteristics of standard fire extinguishers like those from Walter Kiddie, thus making them less applicable in this scenario.
