Chemical Warfare Agent Decontamination Efficacy Testing Large-Scale Chamber mVHP (registered trademerk) Decontamination System Evaluation

摘要

The STERIS Vaporous Hydrogen Peroxide (VHP) technology has been used for more than a decade to sterilize pharmaceutical processing equipment and clean rooms. Through a joint partnership, the U.S. Army Edgewood Chemical Biological Center (ECBC), and STERIS Corporation, Inc., a subsidiary of Strategic Technology Enterprises, began the process to co-develop a modified VHP (mVHP) capable of biological and chemical decontamination. Significant improvements have been made through a series of laboratory, chamber-scale, and large-scale efforts. The primary objective of this test was to determine the mVHP system's ability to decontaminate chemical-warfare agent contamination on operationally relevant materials. The decontamination efficacy was compared to the Key Performance Parameters (KPPs) stated in the Operational Requirements Document (ORD) for Joint Platform Interior Decontamination. In addition, tests were conducted at higher challenges, and cross-comparison tests were conducted to enable comparison to the KPPs stated in the ORD for Joint Service Sensitive Equipment Decontamination. The tests were performed between October 2005 and March 2006 in the Engineering Directorate large-scale chambers at the ECBC, APG, MD. The results for the chemical agent studies are presented in this report.
