Gas generator development for fire protection purpose

High effective Halon fire protection systems were introduced as a technical standard during many years. Because these substances are harmful to the oz one layer, this technology was prohibited. Looking for alternatives in a fi rst step INERGEN or CO2 pressure gas systems were applied, which show stron g disadvantages with respect to extinguishing efficiency and toxicity. As a consequence a new gas generator concept is proposed, based on the idea to produce N-2 by a chemical reaction out of a solid gas generator. The techno logy enables small units of low mass with suitable escape characteristics o f the gas. Within the presented work test results of a model formulation ar e described and discussed.
