Chlorate candle flood system.

Never heard of this system? Let me start out by saying that 688-class submarines do not have this system. But, for both Trident and Seawolf classes, it's a whole different story.

The chlorate candle flood system works identical to the pyro-ammo flood system (In fact they're on the same maintenance index page (MIP) and maintenance requirement card (MRC)). The question, or should I say, the problem is "Who is doing the PMS on the chlorate candle flood system?"

On MIP 5221/017 (in the scheduling aids section) you can see which boats are responsible to accomplish certain maintenance requirements (MRs). Please notice note 2.
1. MRC M-1 is only applicable to SSN 642 and SSN
 645.

2. SSBN 726 Class accomplish MR 1 and MR 2 of
 MRC S-1.

 SSN 21 Class accomplish MR 1 and MR 3 of
 MRC S-1.

 All others accomplish MR 1 of MRC S-1.

* This is a Safety of Ship item.


After reading the scheduling aid (note 2) you might be wondering what MR 1, 2 and 3 of S-1 are. I have included them below.
49 3VPF N 1. Inspect and test pyrotechnic locker flood
 system(s).

 2. Inspect and test chlorate candle storage locker
 flood system.

 3. Inspect and test chlorate candle storage
 locker flood system.


The next thing I want to point out is the maintenance requirement description from MRC S-1 (49 3VPF N).
MAINTENANCE REQUIREMENT DESCRIPTION

1. Inspect and test pyrotechnic locker flood system(s).

2. Inspect and test chlorate candle storage locker
flood system.

3. Inspect and test chlorate candle storage
locker flood system.


Now this is where the problem seems to exist. Everyone onboard knows the torpedoman do #1 (pyrotechnic locker flood system). But, is anyone doing #2 or #3? Should it be the torpedoman or the auxiliaryman? Not sure?

There are several options available for fixing this (e.g., have the torpedoman do it all; have the auxiliaryman do it all; or do a "split-maintenance responsibility" of the MIP and MRC between both work centers). In the case of split responsibility, (approved by executive officer) each work center would omit (department head line out and initial) the MR not applicable to them.

Last but not least, some of the more common discrepancies I see while conducting safety surveys include: missing test plugs, damaged or missing gaskets, missing spanner wrenches and broken glass or no glass over the flood valve. On one unit, the chlorate candle flood system had not been tested in two years!
