Which is considered a clean agent that can replace halons?

Halocarbon agents are considered clean agents as they are designed to extinguish fires without causing harm to sensitive equipment or leaving residue behind, making them suitable replacements for halons. Halons, once widely used, have been phased out due to their ozone-depleting properties. Clean agents, such as halocarbons, maintain effective fire suppression capabilities while being environmentally friendly and safe for use in various applications.

Carbon dioxide, while effective in extinguishing fires, does not fit the clean agent category as it can potentially harm personnel in enclosed spaces due to oxygen displacement. Water mist systems are effective for specific fire types and can cool the fire but do not suppress flames in a manner comparable to halocarbons. Class A foams are specifically designed for solid combustible material fires and leave behind a residue, which does not align with the definition of a clean agent meant to leave no trace.
