IRAP-h View 5.0

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 within the protocol.
