What claims have been made regarding the effectiveness of a CAFS system in terms of time and water usage?

The claim that a CAFS (Compressed Air Foam Systems) system can achieve fire suppression using a fraction of the time and water compared to traditional methods is supported by various studies and real-world applications. Specifically, the assertion that CAFS can do the job in one-fourth the time and utilize one-third the amount of water emphasizes its efficiency. This is due to the way CAFS mixes air, water, and foam concentrate to create a blanket of foam that cools and smothers flames effectively.

By reducing the required time and water for suppression, CAFS systems not only enhance firefighting effectiveness but also conserve vital resources, which is crucial during large-scale incidents or in areas where water supply is limited. This efficiency is particularly valuable in modern firefighting strategies, where rapid intervention is key to minimizing damage and ensuring safety.

In contrast, other claims regarding time and water usage either do not capture the full extent of CAFS's efficiency or overestimate the input required, making option D the most accurate representation of the system's capabilities.
