DTIC AD0600423: MOISTURE IN SURVIVAL SHELTERS

Research on the following problem areas is given: (1) A study of sources of moisture and condensate in occupied and unoccupied shelters including the effects of climate, ground water, permeability, ventilation, latent heat, dew point, and surface temperatures was made. (2) An investigation of promising methods for reducing humidity, preventing leakage of moisture into shelters and controlling moisture and condensate was conducted. (3) Commercial dehumidifying apparatus for use in survival shelters was evaluated. (4) Chemicals which might be suitable for the absorption of moisture and the control of shelter humidity were investigated. Comparative tests were performed on the basis of the information developed during the above evaluations. Conclusions were drawn and recommendations were made with respect to suitable apparatus and procedures necessary for control of humidity and moisture in survival shelters.
