Which of the following is NOT a feature of a clean agent extinguishing system?

A clean agent extinguishing system is specifically designed to suppress fires without causing damage to sensitive equipment and environments. The key characteristics that define clean agents include the fact that they do not leave any residue after being discharged, making them ideal for use in data centers, museums, and other locations where residue from traditional agents might cause harm.

The components of a clean agent system are engineered to be non-corrosive, which is vital for protecting valuable electronic and mechanical equipment. Additionally, these systems are effective against electrical fires, offering a safe and efficient means of extinguishing flames without the risks associated with using water or other extinguishing agents that may conduct electricity.

The requirement of a water supply, however, does not align with the principles of clean agent systems. Clean agents are designed to operate independently of water sources, as they work through gaseous agents that are released to smother the fire. This independence from water is essential in environments where water could actually exacerbate the situation—particularly in electronic or critical data environments. Therefore, the absence of a requirement for a water supply distinguishes clean agent systems from other types of systems that rely on water or foam for fire suppression.
