Easing-out lines, when appropriate, must be
rigged immediately upon rig hookup to prepare for a
possible emergency breakaway.
Personnel in the immediate area of the transfer
station must wear construction-type safety helmets,
equipped with quick-acting breakaway devices. Chin
straps must be fastened and worn under the chin. Safety
helmets will be color-coded as follows:
WHITE Officers, CPOs, and supervisors
WHITE (with green cross) Safety Officer
YELLOW Rig captain
GREEN Signalmen and phone talkers
BROWN Winch operators
PURPLE Repair personnel
RED Line-throwing gunners (or bolo heavers)
WHITE (with red cross) Corpsmen
BLUE Deck riggers and line handlers
ORANGE Checkers and supply personnel
GREY All others
Except forklift truck operators, topside personnel
who are engaged in handling stores or lines or who are
in the transfer area must wear properly secured, orange-
colored, inherently buoyant, vest-type life jackets with
collars. Forklift truck operators will wear inflatable life
jackets fully ready for use: life jacket in front, opened,
with the yoke over the head (except actual inflation).
Personnel rigging aloft or working outboard of
bulwarks or safety chains must wear a properly secured,
orange-colored, inherently buoyant, vest-type life jacket
with a buttonhole in the back cover to permit concurrent
use of the safety harness and safety and working line.
(See Naval Ships' Technical Manual, chapter 077, for
details for use with a safety harness.)
Personnel at a transfer station must wear a one-
cell flashlight (or green chemical light), whistle, and sea
marker (fluorescent) on the outside of their life jacket
during night replenishment. Flashlights need not be
lighted except at the discretion of the commanding
officer. Chemical lights must be lighted, and are not to
be discarded over the side during hours of darkness,
during the replenishment, or until completely
Personnel involved in cargo-handling operations
on both the delivering and receiving ships must wear
Additional safety precautions to be observed
during fueling can be found in NWP 14.
THE SEAMAN ALOFT
LEARNING OBJECTIVE: Describe the
rigging used for going aloft.
As a Seaman in the deck division, you will be
involved in painting or doing repairs while working
either aloft or over the side. To do these tasks safely, you
must be able to correctly rig and use both the
boatswain's chair and the stage. You must also know the
safety precautions involved in working aloft or over the
The boatswain's chair is a hardwood seat attached
to a double bridle of stout line, as shown in figure 4-29.
It is always bent to the gantline by a double becket. A
length of slack end is left hanging, as shown, for use in
securing to masts or stays aloft.
For a straight drop, as when painting down a mast,
rig the chair for self-lowering. When you are coming
down a mast, you will often find that the ladder takes
you only to the crosstree. You must be hoisted from
there to the truck by personnel on deck. When there is
no way of getting to the truck by ladder, a dummy
gantline usually is left reeved from the crosstree up
through the sheave at the truck and back to the crosstree.
The dummy gantline makes it unnecessary for anyone
to climb the topmast to reeve a chair gantline through.
You must never let the end get away from you and reeve
