A modified YOKE is sometimes used at sea when cruising independently in good weather and calm seas and in port in peacetime. In the modified condition, YOKE fi+ttings above the waterline are left open to improve ventilation and habitability. All other XRAY and  YOKE  fittings  shipwide  will  be  closed  unless logged on a case-by-case basis as discussed earlier. An alternative to the setting of ZEBRA shipwide is the setting of modified ZEBRA. An example of the setting of modified ZEBRA would be setting Zebra on the DC deck and below only if the area the ship was transiting  was  a  known  or  suspected  hazardous navigational  area.  This  would  provide  a  higher survivability stance than condition YOKE. At the same time modified ZEBRA is less restrictive in the rest of the ship and will more readily allow the accomplishment of other operational requirements. Modified ZEBRA may result as an upgrade from condition YOKE or as a downgrade from condition ZEBRA. SPECIAL CLASSIFICATIONS Circle XRAY and YOKE. These fittings are access fittings to battle stations and compartments containing equipment that require periodic checks or fittings that must be opened for ammunition transfer, as well as some systems. Circle  XRAY  and  YOKE  fittings  are  normally closed when condition XRAY or YOKE are set. They may be opened without special authority when going to or  securing  from  general  quarters,  transferring ammunition,  during  periodic  space  or  equipment checks,  or  during  operation  of  damage  control equipment.  Circle  XRAY  and  YOKE  fittings  are marked with a black X or Y in a black circle. They should be secured once passage is complete. Circle ZEBRA. These fittings are closed when condition ZEBRA is set. They may be opened with the permission  of  the  CO  only.  This  would  be  during extended periods of general quarters for the preparation and distribution of battle messing, to provide access to sanitary facilities, to ventilate battle stations, to transit from squadron ready rooms to the flight deck, and to allow limited access throughout the ship as the CO prescribes. Open Circle ZEBRA fittings must be guarded so they can be closed immediately because the ship is still in a battle station position when ZEBRA is set. Circle ZEBRA fittings are marked with a red Z surrounded by a red circle. DOG ZEBRA. These fittings are secured when condition ZEBRA is set and whenever the ship is set for “darken ship,” which is a night steaming condition, not a material condition. During darken ship these fittings and closures are closed to prevent light inside showing to the outside. DOG ZEBRA fittings are marked with a red Z surrounded by a black letter D. NOTE Darken ship is a night steaming condition, not a material condition. WILLIAM. These fittings are vital sea suctions, ventilation fittings valves serving vital equipment, and valves that must be open to maintain mobility and fire protection.  WILLIAM  fittings  are  open  during  all material conditions. They are secured only to control damage, contamination, or to repair equipment served. WILLIAM fittings are marked with a black colored letter W. Circle WILLIAM.  These fittings, like WILLIAM fittings, are normally open but are secured for protection in  CBR  attack.  Fittings  that  are  marked  with  this classification are those that provide ventilation opening to the outside of the ship. Circle WILLIAM fittings are marked with a black W surrounded by a black circle.
