Abstract:

The Naval Medical Research Institute received a large human pressure chamber complex in 1977 and began human exposures in 1981. An early incident of organic chemical contamination led to an evolution of contaminant analysis, control, and removal. On the suspicion that poor interior paint was the major proble, the chambers were waterblasted and repainted. Many initial attempts to understand the problem were frustrated by incomplete documentation and conflicting analyses. A series of saturation dives were finally performed in 1985 with a certifiably clean chamber. One contamination incident during these dives was quickly recognized and remedied.
