NAF® S 125 is a UL Recognized and US EPA SNAP Listed gaseous extinguishing agent. NAF® S 125 Engineered Systems are UL Listed. NAF® S 125 is suitable for use in rooms, vaults, enclosed machines, containers, storage areas and wherever fixed enclosures are present. It is an electrically non-conductive media, it can therefore be used to protect electronic and delicate equipment. After discharge NAF® S 125 does not require the clean-up of the protected enclosure, making it extremely useful in applications where damage by other extinguishing methods would be prohibitive. NAF® S 125 has a low order of toxicity. At typical design concentrations it can be safely used to protect normally occupied areas. The NAF S 125® formulation includes a patented additive that reduces the levels of decomposition by-products normally generated by halocarbons during extinguishment and enhances extinguishing performance (inter alia US Patent No. 6,402,975 and EU Patent No. 630,278).
