|Acquisition Program: || Objective: ||The objective of this research is to develop a system for immediate decontamination of surfaces contaminated with biological warfare agents.
|| Description: ||An attack by hostile forces may lead to both exterior and interior surfaces of vehicles, buildings or equipment becoming contaminated with biological warfare (BW) agents. U.S. forces require the means to rapidly decontaminate these surfaces and allow continued and sustained operations. Systems to decontaminate enclosed spaces using a gas or vapor are well known and their efficacy has been demonstrated by numerous tests. Therefore, systems using a gas or vapor are not of interest in this solicitation. The specific focus of this topic is a system that will dispense a liquid to rapidly decontaminate exterior and interior surfaces of forward deployed vehicles and associated infrastructure. The goal of this project is a portable and rapidly deployed solution that will allow continued operations and restoration of operational tempo in the field. This unit may be part of the process of thorough decontamination and subsequent testing that would permit military actions and civilian workers to occupy the decontaminated space for an extended period without any precautions. It is assumed that the normal complement of BW agent or biohazard detection instruments is available, and indicators of the presence of contaminants or level of contaminants need not be part of the proposed system.
The system should satisfy the following requirements: (1) effective (8 log reduction of a 10X8 challenge) on the full range of biological threats, including bacterial and fungal spores, viruses and biological toxins (Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA); (2) safe for the user to dispense requiring minimal personal protective equipment and not requiring evacuation for decontamination of interior surfaces; (3) readily transported to the site of use, including transport on passenger aircraft, with no restrictions due to the presence of hazardous materials or compressed gases; (4) minimal weight and volume; (5) self-contained for maximum mobility, requiring no externally supplied power or materials; (6) readily operated/dispensed; (7) detoxifies rather than sequesters the BW agent, so that there is no biohazard remaining after treatment; (8) environmental friendly, producing no hazardous residues or waste disposal issues; (9) capable of use inside or outside (interior/exterior environments), daylight or dark (i.e., no solar photochemical processes), and in temperatures from -25°F to +120°F; (10) has an extended storage life, minimum two years without loss of decontamination capability; (11) compatible with all materials that may be encountered in military equipment, including personal protective equipment and monitors to detect BW or CW agents; and (12) low cost. The system must comply with the relevant regulatory requirements for manufacture, transport, use and disposal.
Effectiveness against chemical warfare (CW) agents and Toxic Industrial Chemical Materials (TICs and TIMs) is also desirable, provided it does not compromise any of the above properties (1-12 above). This includes complete neutralization of a 10g/m2 load of chemical agent. Materials that have been shown to be effective for biodecontamination include solutions containing hydrogen peroxide and chlorine dioxide; however, any system that meets the stated requirements will be considered.
|| ||PHASE I: Initial research will focus on experiments to demonstrate the technology and formulation, and that the system proposed generates an effective level of decontaminant to potentially meet FIFRA requirements for decontamination. The proposer must demonstrate that the decontaminant is effective against biological agents using appropriate surrogates. Estimation of the system weight, volume, and cost should also be performed.
|| ||PHASE II: The technology developed in Phase I will be incorporated into full-scale, operational prototype units. The prototypes will be tested against suitable simulants for BW agents and, as appropriate and permissible, with live agents. The process to obtain Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) regulatory approval for use in the U.S. should be initiated.
|| ||PHASE III DUAL USE APPLICATIONS: Any additional required testing, including tests against live agents will be performed and effectiveness quantified. This technology will have dual use application both by military forces and first responders. Modified versions may have additional application in military or civilian medical facilities to decontaminate pathogens commonly found on surfaces (a significant source of infections) or remediation against mold in buildings.
