This paper examines the smoke emission and properties of polypropylene and flame retarded polypropylene injection moulded plaques. The prepared samples were irradiated in a Stanton Redcroft NBS type smoke box with an incident radiant energy of 2.5 W/cm 2 . Nucleating agents were also introduced to increase the particle size of the smoke produced. The conclusions reached from this work on the emission of smoke in a non‐flaming mode were that as the flame retardant additive content was increased, the optical density decreased, thus extending the time for escape. The emission of smoke from these polymers subjected to other radiant sources and in a flaming and non‐flaming mode is being investigated further.
