What is the main advantage of using clean agent extinguishers?

The main advantage of using clean agent extinguishers is that they leave no residue after use. This feature is particularly important in environments where sensitive equipment, such as electronics, computers, or valuable documents, are present. Clean agent extinguishers utilize gaseous agents, which effectively suppress fires without the mess and cleanup associated with traditional extinguishing agents, like water or foam. Consequently, they minimize damage to both the fire-affected area and the objects within it, allowing for a quicker and less costly recovery from fire incidents.

The other options describe aspects that may not accurately reflect the unique benefits of clean agent extinguishers. While cost and maintenance are practical considerations, they do not specifically highlight the primary functional advantage of leaving no residue, which is essential in many commercial and industrial applications.
