Why each option
FM-200 (HFC-227ea) is the widely adopted clean-agent fire suppressant that replaced halon gas after halon was banned for ozone-depleting properties.
FM-200 is a hydrofluorocarbon (HFC-227ea) clean agent that suppresses fire by absorbing heat without depleting oxygen or leaving residue. It was developed specifically as a halon replacement after the Montreal Protocol restricted halon use due to its ozone-depleting characteristics. It is safe for use in occupied spaces and for protecting electronic equipment.
CO2 suppresses fire by displacing oxygen and is dangerous to occupants, making it a different class of suppression agent, not a direct halon replacement for occupied spaces.
SO2 (sulfur dioxide) is a toxic gas and is not used as a fire suppressant or halon replacement.
Ozone is a reactive oxidizer - it is actually what halon damages - and is never used as a fire suppression agent.
