forecastle. In letting go the anchor, the brake operator
must wear goggles while handling the brake.
Ring buoys with a line and light attached must be
available for use when a sea ladder or a Jacob’s ladder
is being used.
LIFELINES
Personnel are not permitted to sit or lean on the
lifelines at any time. Lifelines are safety barriers to
prevent personnel from falling or being washed over the
side. When lifelines are removed for any purpose, the
officers and petty officers concerned are required to
ensure that emergency lines are rigged and that everyone
has been cautioned to keep clear. While working over
the side in port or at sea, personnel must wear life
jackets, safety harnesses with safety, and tending lines
attached, and a safety helmet.
When the ship is underway and a crew member has
to work outside the lifelines, permission must be
obtained from the commanding officer.
At sea, weather decks of ships can be extremely
hazardous, particularly aboard small ships. At any
moment, the sea can submerge the main deck to a depth
of several feet or a wave may come unexpectedly over
the bow or fantail.
If your duties do not require you on the main deck,
do not go there. Be aware of any locations on deck that
present any tripping hazards. Line handlers should stand
at least 6 feet away from the block through which the
line passes. Always stand clear of the bights of a wire
rope or a line.
During heavy weather, don't go on deck unless the
officer of the deck gives you permission. Then, work in
pairs and wear inherently buoyant (kapok) life
preservers, safety harnesses, and safety lines.
CRANES, CAPSTANS, WINCHES,
AND WINDLASSES
Only trained personnel and those who have been
authorized specifically by the first lieutenant are
permitted to operate cranes, capstans, winches, and
windlasses. Except in an emergency, operation of the
machinery must be supervised by a responsible officer
or petty officer. The method of operation and all
necessary special instructions must be posted at the
place of operation.
Experienced personnel must always supervise the
topping and lowering of booms. Before making any
repairs or replacing any of the gear, personnel should
always lower the booms on deck. Chapter C6, Volume
2 of OPNAVINST 5100.19 (NAVOSH Program
Manual for Forces Afloat) contains safety precautions
on cranes, capstans, winches, and windlasses.
LUBRICATING WEATHER DECK
EQUIPMENT
LEARNING OBJECTIVE: List and explain the
importance of lubricating weather deck
equipment.
All weather deck equipment must be lubricated
properly to ensure protection against wear and weather
elements. This section deals with the lubrication of the
boat davits, standing rigging, running rigging, and the
like.
WARNING
All greases, lubricants, and cleaning
compounds are hazardous materials. Avoid
prolonged skin contact and always wear
goggles when using these materials. Use in a
well-ventilated area.
BOAT DAVITS
Inspect boat davits as required by the Planned
Maintenance System (PMS) schedule. Follow the
regular lubrication of the mechanical parts as outlined
in the individual manufacturer's manual and PMS. Coat
the davit wire rope falls, gripes, and latch-releasing
devices with grease. Be sure to apply grease thoroughly
to the areas where saltwater would form a pocket.
Examples of these areas are next to shackles buttons or
cramps, and around the thimble.
STANDING RIGGING
All exposed wire, whether galvanized or not, must
be covered with some surface coating for protection
against the weather. For wire in standing rigging not
subject to wear, weather protection is the only important
consideration. The Maintenance Requirement Card
(MRC) lists the preservatives needed. You can get them
by submitting a supply requisition to the supply
department.
RUNNING RIGGING
Wire rope for running rigging, as on cargo winches,
must be covered with a mixture that provides
lubrication as well as protection against the weather. A
preparation of graphite and grease makes an excellent
covering for running wire if no prepared mixture is on
hand.
