NFPA 2001 has defined the term "clean agent" as an electrically nonconductive, volatile, or gaseous fire extinguishing agent that doesn't leave a residue once they extinguish a fire. A clean agent fire suppression system is made up of an inert gas or a chemical that's stored during a container and discharge it, when necessary, to extinguish a fireplace in its initial stage. There are many benefits to using a clean agent fire suppression system. These systems are fast, effective, safe, clean, and eco-friendly. The clean agent systems are three-dimensional as well. Most systems can reach extinguishing concentration levels in just 10 seconds or less. Clean agents are designed to suppress the fire while it's still in its initial stage, meaning it will suppress the fire before it grows and enters into the heat/flame stage. The clean agents that are dispersed in a fire suppression system are safe to use in areas populated by humans and are non-ozone reducing with a short or no atmospheric lifetime. There is no costly clean-up once the clean agents have been discharged because they are fast vaporizing gases that do not leave a residue after they dissipate.
