As part of the qualification of the International Space Station (ISS) Fine Water Mist (FWM) Portable Fire Extinguisher (PFE) several test methods were developed to determine against stored energy sources. The most challenging of these devised stored energy fire test methods proved to be the Li-Ion battery fire test scenario. The intended use of new water based PFE technology on the Orion Crew capsule spurred the need for the same type of evaluation focused on the sources of stored energy slated for use on Orion. Laptops were identified as a realistic potential source for potential stored energy fires requiring a modified li-ion battery fire test scenario. In addition to open test cell (ambient oxygen concentration) testing to evaluate new proposed PFE performance, sealed chamber (20.9 & elevated oxygen concentration) testing was also performed. Chamber testing included combustion product sampling at various fire progression points for analysis and application to Orion emergency equipment design and response planning. Fire extinguisher stored energy fire test methodology was modified and testing performed. Initial tests indicated ignition of the magnesium cases was possible and further testing was performed to assess the damage potential of the new risk as well as the use of new Water Spray PFE as a means to combat this type of fire. The new Water Spray PFE technology proved effective in extinguishing laptop stored energy fires and much was learned in the way these types of fires progressed., Findings indicate potential Mg ignition mitigation strategies to be further investigated.
