A recompression chamber system must have a primary and a secondary air supply
system that satisfy the following requirements.
-
Primary. Sufficient air to pressurize the inner lock
once to 165 feet and the outer lock twice to 165 feet and ventilate
during one Treatment Table 4 (Chapter21).
-
Secondary. Sufficient air to pressurize the inner and
outer locks once to 165 feet and ventilate for one hour at 70.4 scfm.
Capacity. Either system may consist of air banks and/or a suitable compressor.
The primary recompression chamber support system must be capable of pressurizing
the inner lock to a depth of 165 feet. The required total capacity is calculated
as follows.
