What characteristic distinguishes clean agents from other extinguishing agents?

Clean agents are distinguished by their non-flammability, meaning they do not support combustion. These agents are specifically designed to extinguish fires without leaving any residue that could damage sensitive equipment or materials, making them ideal for protecting electronic devices and valuable property.

Unlike other extinguishing agents, which can leave a residue (like foam or powder), or are water-based (which can contribute to damage), clean agents offer a clean, effective way to suppress fires without adding to the cleanup burden post-incident. Additionally, clean agents are effective against various types of fires, including electrical fires, thus ensuring safety in environments where electrical equipment is present.
