Study on Overpressure Protection System of Air Contaminations for Mobile Medical Shelters

Abstract

A design of overpressure protection system is presented for the mobile field medical shelters. The system compositions, structures and installations were comprehensively designed and manufactured by the modular analysis method according to the characteristics of defensive logistic operations for chemical, biological, radiological and nuclear air contaminations to the mobile field hospital. The effects of overpressure protection system were verified through a series of experiments on different shelters, which showed that more than 300 pascals overpressure could be achieved in the separate expanded shelters, and more than 100 pascals overpressure could be achieved in the interconnected expanded shelters. The experiments indicate that the overpressure protection system can meet the demands of relevant protection standards, and can provide effective protection for the medical shelters under suddenly CBRN contamination attacks.
