What type of fire suppression system uses the local and total flooding method?

The CO2 systems utilize both local and total flooding methods for fire suppression, making them particularly effective in enclosed spaces. In the local flooding method, CO2 can be concentrated in a specific area to suppress flames and prevent further fire spread, which is useful for protecting specific equipment or sections. The total flooding method involves filling an entire room or area with CO2 to displace oxygen and effectively smother the fire. This dual approach allows CO2 systems to be flexible in application depending on the fire's nature and location.

In comparison, water-based systems primarily use water and are more suited for general applications rather than localized suppression. Foam systems, while effective for flammable liquids, do not typically use flooding methods in the same way CO2 does. Dry chemical systems excel in rapid suppression of various fires but rely on interrupting the chemical reaction rather than the flooding method employed by CO2 systems. This highlights the unique advantages and functionalities that CO2 systems offer within fire suppression techniques.
