Correct me if I'm wrong, but I believe that the USDCT was planning on
using scatol as a drysuit inflation gas.  There were several documented
instances where, due to the natural over production of this gas,
spontaneous combustion was observed when oxygen was inadvertently
released into the drysuit. Unlike HPNS scatol is very common when HFS
are involved in dive operations.  This is a particular problem after
NSS-CDS socials.
