25 -- FIRE EXTINGUISHING SYSTEM AND AGENTS POC Richard Gale (810) 574-7602 E-MAIL: Click here to contact the POC, galer@tacom.army.mil. The Program Executive Officer for Ground Combat Support Systems (PEO-GCSS) is seeking sources for the proposed procurement of an off-the-shelf fire extinguishing system (FES) and agents for use in Army ground vehicle crew compartments. All candidate systems must be retrofittable into current ground combat vehicles. The FES must prevent second degree burns to vehicle crewmen; that is, the exposure temperature less body temperature integrated over 10 seconds should not exceed 2400 degrees F-sec. In use, the crew compartment overpressure shall not exceed 11.6 psi, agent concentrations shall not exceed the no Observable Adverse Effect Level (NOAEL), acid gas byproducts shall not exceed 1000ppm, and oxygen levels shall not drop below 16%. The FES must extinguish all flames within an Army ground vehicle crew compartment. The extinguishant must be effective in extinguishing Class B, Class C, and combination A/B fires. The FES extinguishant(s) and pyrolysis products must be environmentally safe. The ozone depletion potential (ODP) shall be 0.00. All materials must be (US) Environmental Protection Agency (EPA) Significant New Alternatives Program (SNAP) approved/listed. All materials, chemicals, and/or agents released by the FES, should have the lowest possible Global Warming Potential (GWP) and atmospheric lifetimes. If the FES uses electrical-manual activation, the system shall operate on 24 plus or minus 6V DC at 30 amps maximum to activate the extinguishant discharge. The FES shall be capable of operation over the minimum temperature range of minus 25 F to plus 140 F. Minimum storage temperature range for the FES shall be minus 65 F to plus 160 F. The FES shall be fully operational within one hour of the ambient temperature entering the temperature range without any maintenance. The FES effluent shall not cause unacceptable ie., mission impacting, corrosion or equipment degradation. Cleanup of the discharged extinguishant shall be minimized. The extinguishant must be safe to handle and use. Sufficient toxicological data must be available to support the approval process of the Army Surgeon General. The system shall pose no threat to the crew or maintenance personnel. The maximum extinguishant storage volume required to extinguish any test fire shall not exceed a total of 10 liters.
