IRAP-h View is a user-friendly graphical interface for conducting a comprehensive multi-pathway human health risk assessment. It simultaneously calculates risk values for multiple chemicals, from multiple sources, at multiple exposure locations.
Regardless of experience, risk assessors, trial burn planners, permit writers, and toxicologists can readily produce expert results and professional reports. Most of all, they are completing these projects within only a fraction of the time and cost traditionally absorbed during in-depth risk assessments.
IRAP-h View implements the latest U.S. EPA - OSW Human Health Risk Assessment Protocol (HHRAP), ensuring users' step-by-step process meets the criteria set forth in the protocol.
IRAP-h View covers many human health risk assessment guidance and procedures such as:
IRAP-h View incorporates features designed by experienced meteorologists and engineers who routinely work with risk assessment programs. This ensures it meets the practical needs of today's modelers for successful and efficient performance.
Fully integrated GIS-based interface with easy-to-use graphical tools.
Includes the full US EPA database of Compounds of Potential Concern.
Visualize your plot risk results and COPC concentrations.
IRAP-h View contains many features designed to reduce completion of risk assessment projects from months to days. This means significant savings in time, resources, and costs.

IRAP-h View offers a user-friendly graphical interface with intuitive tools for conducting risk assessments. It simplifies the process of performing risk calculations and generating detailed reports. The graphical tools are designed for ease of use, enhancing efficiency throughout the project. Comprehensive output reports provide clear and thorough results, supporting informed decision-making.
Includes the complete U.S. EPA database of Compounds of Potential Concern (COPCs). This database comes fully integrated with fate and transport parameters for each chemical. Users have direct access to this extensive information, enhancing the accuracy of risk assessments. The inclusion of these parameters streamlines the modeling process and supports comprehensive analysis.


Allows you to plot both risk results and COPC concentrations, providing exceptional visualization of your data. These plots enable users to clearly interpret and analyze outcomes. By visualizing risk and concentration data side by side, users gain deeper insights into their assessments. This feature enhances the overall clarity and effectiveness of the risk analysis process.
IRAP-h View enables the analysis of multiple risk receptors, chemicals, and scenario parameters within a single project. This feature allows users to evaluate complex situations more efficiently. By handling multiple variables simultaneously, the tool streamlines the risk assessment process. It provides comprehensive results that account for various factors in a single workflow.


IRAP-h View generates a comprehensive set of tables that summarize risk and concentration values. These tables make it easy for users to quickly access and review their results. The clear organization of data enhances the efficiency of analyzing risk assessments. This feature ensures that all key information is readily available for informed decision-making.
