Which type of system floods an enclosure with agent?

• A. Total flood
• B. Local protection
• C. Fixed aerosol
• D. Portable application

Answer: (C)

Flooding an enclosure with agent means releasing an extinguishing substance so that it permeates and fills the entire space, not just a localized spot. A fixed aerosol system does exactly this: it uses permanently installed release devices that discharge a fine aerosol into the room, quickly distributing throughout the enclosure to reach every corner. This is what makes it the best fit for “flood an enclosure with agent.” Local protection targets a specific area or item, not the whole room. Portable application relies on handheld cylinders and can’t achieve a full-space flood without manual intervention. While total flood can involve filling an area with a substance, fixed aerosol is specifically the system designed to flood the entire enclosure with an aerosol.
