Safety Science and Technology, EarlyView.This flame‐retardant epoxy composite realizes synergistic fire suppression via gas‐phase and condensed‐phase dual mechanisms. In the gas phase, phosphorus‐containing radicals trap active H· and OH· radicals to interrupt flame combustion chain reactions. In the condensed phase, Fe species act as Lewis acid co‐catalysts to promote char formation, and the
