A new methodology for estimating nerve agent (Sarin (GB)/VX) casualties as a function of time: Implementing the human response injury profile nerve agent methodology

The Human Response Injury Profile (HRIP) methodology uses time-based progressions of underlying symptoms and their severity changes over time to determine user-defined casualty and fatality estimates from chemical, biological, radiological, and nuclear (CBRN) events. This paper provides an overview of the implementation of the HRIP nerve agent methodology for use in estimating casualties resulting from Sarin (GB) and VX exposure. The article describes inputs, human response, and the casualty estimation processes. Additionally, examples are provided to show how multiple exposure routes can be combined to estimate the composite injury and resulting casualty effects.
