How To Throw Out The Trash!
This, my friend, is part of the chores
you had to do to have that many people living in a steel tube. Just like blowing
the sanitary tanks.
What we have is it step by step procedure for shooting the TDU. Trash Disposal Unit. It's a small torpedo tube affair, with a ballvalve in the end. That's how they
dump the trash. Weighted it goes straight to the bottom. Now days, I believe that is kept to a minimum.
TDU FLUSHING PROCEDURE:
MAN JA PHONE AT BCP, TDU, AND PIPING SPACE.
OPERATE TDU USING FOLLOWING PHRASEOLOGY AND STEP BY STEP PROCEDURE;
