Abstract : This report documents the results and findings of dead air space tests on the chemically protected deployable medical systems (DEPMEDS) conducted at Fort Indiantown Gap, PA. The DEPMEDS are composed of various size overpressurized chemically protected shelters connected by viaducts. Designed by the U.S. Army Natick Research, Development and Engineering Center (NATICK), the shelters provide a clean air conditioned atmosphere to treat wounded personnel in a chemical warfare environment. NATICK requested the U.S. Army Chemical Research, Development and Engineering Center's support to identify any dead air spaces, because these spaces would be a potential chemical agent vapor accumulation location, and threaten the collective protection of the shelters. Initially, a smoke generator was utilized to observe the air flow patterns within the DEPMEDS, and suspect dead air space locations were identified. However, subsequent dissemination of sulfur hexafluoride into the ventilation system of the shelter indicated that no dead air spaces were present. This report includes a few suggestions to improve the air circulation of the DEPMEDS, namely elimination of the interior shelter liners and using doors between the viaducts connecting the various shelters.
