Methodology Assessment for Chemical Hazard Mitigation Technology Evaluations Using Multiple Panel Types

Abstract

This report presents a methodology assessment for chemical hazard mitigation technology testing using multiple panel types.The methodology is used to analyze decontaminant performance and to translate the laboratory results to enable operationally relevant health-based assessments for vapor and contact exposure. A new shim panel (two materials separated by a variable thickness shim spacer) is introduced to quantify the effects of materials configurations that limit fluid access on agent retention and decontaminant performance. This effort employs the retained agent (RA) analysis method, which determines the total quantity of agent associated with a panel (or similar) after a treatment procedure. The methodology assessment includes aspects of verification and validation to establish the reproducibility of the output. A new scale-up calculation is established that utilizes per drop-normalized retained agent data from panels to predict the retained agent response on full-scale assets. Contamination and decontamination evaluations of small assets were performed in this assessment to demonstrate prediction within a factor of 210. Additionally, a calculation for maximum potential dose is introduced that assumes that all agent mass associated with the asset produces vapor or contact exposures, which enables the use of retained agent data to evaluate technologies to health-based decontamination requirements.
