IG-541 Summary

IG-541 is an eco-friendly fire extinguishing agent listed as "IG-541 (N₂: 52%, Ar: 40%, CO₂: 8%)" by the National Fire Safety Standards (NFSC 107A) and the American Fire Protection Association (NFPA 2001).

characteristic

· As a substitute for halon extinguishing agents, developed countries have researched and developed alternative drugs and systems since 1994 and used them since 1994.
· Electrically non-conductive
· No residue after evaporation
· The main principle of extinguishing fire is to block oxygen.
