When should a total flooding system be used?

A total flooding system is designed to discharge its extinguishing agent throughout an enclosed space to achieve a concentration that effectively suffocates a fire. This method is most effective in areas where a total flooding setup can ensure the entire volume of the protected space is filled with the extinguishing agent, allowing for rapid and complete coverage of the fire.

The correct context for the use of a total flooding system is within a permanent enclosure, such as a room or a structure with defined walls and a ceiling. This containment allows the agent to work effectively without dispersing into areas that are not at risk. Proper sealing of the enclosure is critical to maintain the concentration necessary to extinguish the fire.

In contrast, other situations such as handling flammable liquids, responding to surface fires in open areas, or emergency evacuations do not align with the optimal use of this type of fire suppression system. For example, flammable liquids often require specific suppression methods tailored to risky fire behavior unique to those materials, while open areas do not provide the containment needed for total flooding, as the agent would not remain concentrated. Emergency evacuations typically prioritize safe exit routes and may not involve active firefighting measures in the immediate response phase.
