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. 4-45
