Many ships, such as carriers, tankers, and
tugs, have independent diesel-driven fire pumps.
If ships pumps and firemain are damaged, these
diesel-driven pumps can be used to furnish large
amounts of water for firefighting purposes.
LIGHTING SYSTEM
On ships using a.c. generators, the ships serv-
ice and emergency lighting systems are energized
from the generator and distribution switchboards
through a bank of transformers. These
transformers supply power to the lighting system
through the lighting distribution panels.
Lighting throughout the machinery spaces is
supplied from the normal switchboard for the
compartments involved, with some lights in each
space supplied from the alternate switchboard. A
few lights in each compartment are supplied
through automatic bus transfer equipment from
circuits originating at the emergency switch-
boards. A few lights in each compartment are sup-
plied through automatic bus transfer equipment
from circuits originating at the emergency
switchboards.
Automatic type hand lanterns are provided to
supply an instantaneous source of illumination,
in the event of complete failure of the ships serv-
ice and emergency lighting systems. These relay-
operated hand lanterns are installed at vital
stations. In addition to these, nonautomatic type
hand lanterns are also installed at these stations.
An EN1 or ENC in charge of an engineering
space has the supervisory responsibility to see that
the hand lanterns, especially the automatic type,
are not removed except for actual intended use,
and that hand lanterns are available for use at all
times. Although the Electricians Mates have the
responsibility for the maintenance of the hand
battle lanterns, it is the duty of the petty officer
in charge of the space to see that personnel do
not remove the lanterns or use them for
unauthorized purposes.
The EN1 or ENC should also ensure that per-
sonnel have an adequate number or flashlights
available for use should all the lights in an
engineering space go out.
ELECTRICAL POWER PANELS
AND TERMINALS
Power panels are supplied with two or three
sources of powernormal, alternate, and
emergency. These panels are equipped with cir-
cuit breakers or switches which permit the transfer
from one source to another in the event of a
casualty.
Regular electrical outlets are installed
throughout the engineering spaces for use with
small portable tools; multipurpose outlets are in-
stalled in selected locations for use with portable
submersible pumps and portable welding sets.
These outlets are located so that it is possible to
use two portable submersible pumps in any water-
tight compartment. Portable triple outlet ex-
tension cables are provided to permit the
concentration of all submersible pumps in one
area. An adapter provided with these extension
cables permits connection of the submersible
pumps to the casualty power terminals. All this
equipment is stowed in the damage control
lockers.
Engineroom personnel should be trained in the
emergency use and operation of submersible
pumps as well as other damage control equipment.
They should know the location of both normal
and emergency power outlets in their spaces, and
should understand the different methods used to
supply electrical power for operating submers-
ible pumps in the engineroom.
Engineroom personnel should also be familiar
with sources of electrical power provided to the
different power panels in an engineroom. Dur-
ing engineering casualty control drills and during
actual emergencies, the Enginemen should be able
to shift from one source of electrical supply to
another.
BATTLE CASUALTIES
As an EN1 or ENC you will be responsible
for handling battle casualties, you will have to
know the location of isolating and cross-
connecting valves, and recognize which of the
valves are remotely controlled. As a general rule,
personnel safety will be your first consideration
in handling casualties.
Effective control of battle casualties depends
on a good knowledge of the principal engineer-
ing piping systems and related equipment. This
information may be found in the ships Engineer-
ing Casualty Control Manual, in the Damage
Control Book, in the plans of the principle
