Title:
Aerosol Travel through Ventilation Systems
Report Date:
1957-06-11
Abstract:
Polydisperse aerosols of dioctylphthalate with a particle-size range of approximately 1- to 20-u, diameter were passed into two typical ventilation air systems. The effect on particle-size distribution and concentration was studied at various sampling stations throughout the system by means of a jet-Impactor, light-scattering method. In general, aerosol particles larger than 3-u diameter were removed to varying degrees by the system components while smaller particles were essentially unaffected. It was concluded that building ventilation systems could not be relied upon to provide adequate protection from a biological warfare aerosol attack.
