A fire-resistant, essentially halogen-free one part epoxy resin composition, that emits very low amounts of smoke and toxic gas comprises: (a) 100 parts by weight of an organic epoxide compound having an epoxide functionality of at least 1; (b) about 2 to 180 parts by weight of an epoxide hardener; (c) about 0.5 to 40 parts by weight of a film-forming material; (d) about 0.5 to 30 parts by weight of a foaming agent; and (e) about 60 to 230 parts by weight of a substantially halogen-free fire resistant system that includes a mixture of: (1) a smoke suppressant selected from the group consisting of alkaline earth metal hydroxides, aluminum group hydroxides and mixtures thereof, and (2) a phosphorus-containing material preferably encapsulate red phosphore. The composition meets the fire, smoke density and toxic gas emission requirements of ATS 1000.001 specification.
