The project which forms the basis for this handbook was an investigation of aerosol behavior in high pressure environments. Deep submergence saturation diving havitats utilize synthetic respirable atmospheres at hydrostatic pressures equivalent to the depth, and allow free diver excursions to the surrounding sea for tasks such as marine research, salvage and mining. During extended submerged operations, recycled respiration gas atmospheres may become contaminated by emissions from construction materials, protective coatings, instruments, control system components, and from occupants and their operations and activities associated with prolonged habitation in a closed environment. The specific environment considered was the helium-oxygen atmosphere used in saturation diving environments for depths to 1,000 feet. In order to proceed in as logical a fashion as possible and yet deal with the several interrelated aspects of the problem simultaneously, a clear statement of goals was necessary. 1 Investigate and extrapolate the possibly altered behavior of aerosols in the helium-oxygen environment. 2 Determine methods for removing potentially harmful aerosols from the environment. 3 Determine possible altered toxicological behavior of aerosols.
