Learning Objectives: When you finish this chapter,
you will be able to
Identify the communications devices used
during damage control evolutions.
Recognize the purpose of communications
devices used during damage control evolutions.
Communications are vital to the damage control
organization. Without good communications, the entire
organization could break down and fail in its primary
mission. The size and complexity of the surface ships
govern the design of DC communications systems

communications systems are as follows:
All the systems listed below are explained in
detail in chapter 4 of this TRAMAN.
Ships service telephones
The X40J is an emergency damage control
communication system. Its employed in the event of
primary, auxiliary, and supplementary communications
circuit failure. The X40J is composed of both portable
(salt and pepper line) and permanently installed
The general announcing system (1MC) is
integrated with a system of alarm signals. The signals
override the microphone control stations and are
intended to notify the ships crew of imminent danger.
These alarms, in order of priority, are as follows:
2. Chemical attack
4. Flight crash
The OOD/conning station sounds this alarm signal
when there is a possibility that the ship will run into a
pier, run aground, or another waterborne unit will strike
the ship. All hands should move away from the area of
impact and brace for shock. After a collision, all hands
set material condition ZEBRA and are prepared to
control fires and flooding.
Chemical Attack Alarm
The chemical attack alarm signal is sounded by the
OOD/conning station, DCC, and automatically by the
chemical agent point detection system (CAPDS) on
