FW: Gas Tank

["Scott Dickson" <sdickson@ksu.edu>]

When work (such as welding) needs to be done on underground fuel storage
tanks they are first completely drained and allowed to vent for a period to
allow any residual fuel to volatilize.  Then some dry ice (solid CO2) is
placed in the tank which sublimates (goes from solid to vapor state) and
displaces any oxygen that is necessary for combustion.  I assume this would
also be applicable to a Healey tank.
