Feasibility of Developing a Human Simulator for CBRN IPE Testing

The U.S. Army Edgewood Chemical Biological Center ECBC evaluates the ability of individual protective equipment IPE to mitigate chemical, biological, radiological, and nuclear CBRN exposures. In support of this, the Respiratory Protection Team ECBC developed and evaluated advanced test systems and methods to better understand respirator performance under operational conditions. The objectives of this effort were to define the requirements for an advanced test manikin for evaluating CBRN respirators and perform a market survey to identity applicable technologies for potential incorporation. The requirements were defined in coordination with the National Institute for Occupational Safety and Health. Features desired included, but were not limited to, a skin-like sealing surface, correct anthropomorphic dimensions, simulation of metabolism i.e., oxygen consumptioncarbon dioxide production, versatility of wave forms for human breathing, generation of heat and perspiration, upper body articulation, movement of face and jaw, simulation of vision, and integrated sample ports. The market survey results were compared with the requirements to assess feasibility and identity the technology gaps. The development of the simulator was divided into three phases, with the Phase I meeting the minimum requirements for fit testing protecapplication. A development plan for the Phase I simulator was outlined.
