How long does a lavatory fire extinguisher discharge when activated?

The duration for which a lavatory fire extinguisher discharges when activated is between three to five seconds. This short discharge time is specifically designed to limit the amount of time passengers and crew are potentially exposed to fumes, while still effectively suppressing fire in the lavatory area.

The brief discharge duration aligns with safety protocols, ensuring that the extinguisher can be used quickly and effectively in an emergency situation. This is critical in maintaining the safety and well-being of passengers and crew on an aircraft. Understanding the operational characteristics of onboard fire safety equipment is essential for flight attendants, as it equips them with the knowledge needed to respond effectively in the event of a fire.
