Total flooding system is defined as which of the following?

Total flooding systems are about saturating the entire volume of an enclosed space with an extinguishing medium so every part of the fire area is reached at the required concentration. The foam option fits this idea because it describes releasing foam into a compartment and allowing it to fill the space completely, creating a blanket that cools the fuel and displaces or suffocates the fire. This contrasts with ideas of just applying agent locally at the fire, using a dry chemical in a non-flooding scenario, or focusing on enclosing structures without flooding the space.
