A Solid-Solid Hybrid Gas Generator Fire Suppression System

This Phase 2 proposal addresses the advanced development and commercialization of a novel solid-solid hybrid gas generator fire suppression technology to replace the ozone depleting Halon 1301 for total flooding applications. Mainstream's solid-solid hybrid gas generator technology will result in the delivery of chemical extinguishing agents to the fire in addition to the inert gas agents. This technology has several advantages over state-of-the art gas generator fire suppression technology. First, the system will be significantly smaller and lighter than current gas generator systems because it results in chemical, in addition to physical, extinguishment of the fire. Second, the entire hybrid gas generator material is stored in a single storage vessel as a solid, compared to other hybrid systems which require a separate pressure storage vessel. Third, the hybrid gas generator material has acceptable atmospheric and toxicological properties, unlike other hybrid gas generator systems that use the agents HFC-227ea., HFC-236FA, or CF3I.
