industry event - contingency plans

[LIPTONW@detroitedison.com]

A recent industry event, involving personnel and area contamination, occurred 
when individuals attempted to disconnect a clogged hose that had been used to 
pump a radioactive sludge with an air driven pump.  The hose was still 
pressurized, and sprayed highly radioactive sludge.  It's my understanding 
that, although the persons involved thought that they had depressurized the 
hose before disconnecting it, there was residual pressure trapped by the clog. 
  
 
My question is:  Does anybody have a contingency plan for disconnecting a 
clogged hose which is or may be under pressure?  Such a plan would probably 
involve disconnecting the hose within a containment.  I'd appreciate any 
information on how such events are managed.  Please respond via RADSAFE or 
directly to me."
