combination. Before doing so, the custodian may, if he
so desires, conduct an inventory of the stores in the
Grand Master Key
The supply officer is required to maintain in his
custody a grand master key, which will open all locks
in groups I, II, and IV. It will NOT open locks in group
III. If authorized by the supply Officer, duty supply
officers or duty petty officers may pass the duplicate
key between them when the number of supply officers
aboard is such that the senior petty officers are required
to set as department duty officers.
GROUP IV All of the ships service activities
(barbershop, tailorshop, laundry, cobbler shop, and
photographic shop) when cash sales are not made
through them, or no material for cash sale is stowed
therein. When the latter conditions exist, these sprees
are placed under group III.
Each lock in group IV must have an original key
different from the keys to other spaces. It must be kept
by the person in charge of the space during working
hours. After duty hours, the person in charge of the
space must turn the key over to the duty petty officer for
safekeeping in the key locker in the supply office. A
duplicate key for each space is safeguarded in the same
manner as for group I.
The supply officer or the
designated assistant retains in his custody a master key
(original) to all locks in group IV. The supply officer
retains the duplicate master key in his custody.
Figure 6-4 illustrates typical custody with regard to
keys. Study and become familiar with it.
Sets of locks containing locks for group I, II, and
IV supply spaces, are available in various sizes to meet
the requirements of different ships. When a single
series padlock set is inadequate to meet the needs of
large ships, more than one set may be used. For
example, one set for group I and a second set for groups
II and IV.
