The invention is directed to a chemically active fire suppression composition, comprising a propellant comprising a fuel and an oxidizer, the propellant capable of generating inert gas; and an environmentally innocuous chemical fire suppressant capable of generating fire suppressive reactive species. The combination of physically acting fire suppression agents and chemically acting, environmentally innocuous fire suppression agents results in a highly effective, environmentally innocuous fire extinguishing composition that has low ozone depletion potential (ODP), low global warming potential (GWP), and high suppression efficiency.
