When unscheduled maintenance is identified and the facility
does  not  have  a  manned  dive  in  progress,  then  the  required
maintenance  will  be  treated  as  scheduled  maintenance.  T h e
maintenance action will be scheduled maintenance periodicity code
preceded by a "U" (i.e., US-2).  Unscheduled maintenance identified
while the facility has a manned dive in progress is dependent upon
the HAZCAT of the equipment involved as previously discussed in
Section 3,  paragraph 2,  of this chapter.
Further  guidance  on
managing  and  conducting  such  maintenance  is  provided  in  the
paragraphs that follow.
3.5.2
Manned-Operations Failure Management Planning (FMP).
As previously discussed in Chapter 2, Section 6, failure management
planning (FMP) is required for HAZCAT II items.
Such  planning
requires the integration of the following:
Emergency procedures.
o
o
Maintenance procedures.
o
Spare parts availability.
o
Further, failure management planning (FMP) involves:
Analyzing HAZCATs.
o
Review of emergency procedures.
o
Review
of
maintenance
mechanism
&
control
o
responsibilities.
Establishment of approved maintenance procedures.
o
Review of spare parts availability & maintenance.
o
Personnel indoctrination & Training.

3.5.3
Manned-Operations  Failure  Management  Maintenance
(FMM).  FMM involves the actual implementation of the FMP.  T h e
following steps outline the procedures for conducting FMM.
a.
Step  1  in  FMM  is  the  initiation  of  the  applicable
emergency procedure (s).
When the chamber occupants have been
isolated from the immediate danger,  the  secondary  life-support
system is known to be functioning properly, and the situation is
firmly under control the unscheduled maintenance can be initiated.
b .  Step 2 in FMM is the control of maintenance operations.
This involves strict liaison between the Dive Watch Supervisor and
the  Maintenance  Supervisor.
The  Dive  Watch  Supervisor  is
responsible  for  ensuring  that  the  system  is  lined  up  so  that
maintenance can be conducted, re-entry control initiated and tag-
out procedures followed.  The Maintenance Supervisor is responsible
for providing the maintenance check-off sheets and ensuring that
the proper materials, tools and people are ready to conduct the
maintenance.
Prior  to  conducting  the  maintenance  action  the
Maintenance Supervisor must receive an approved REC sheet signed
by the Dive Watch Supervisor.
