Compartment number 2-79-11-A ✔ - 2- deck
79- frame (forwardmost frame of comp is 79)
11- relation to centerline (6th comp on starboard side 1,3,5,7,9,11)
A- compartment
x-ray ✔ - -set when in no danger of attack
- secured during x,y, and z
- eg. ship in anchor in well protected harbor
circle x-ray ✔ - -closed when condition x ray set -may be opened without permission, but closed immediately
yoke ✔ - -maintained at sea during peacetime, and in port during wartime, and in port during peacetime outside of regular working hours
-secured during conditions yoke and zebra
circle yoke ✔ - -closed when yoke is set
-may be opened without permission but must be set immediately
zebra ✔ - -closed when condition zebra set
-once condition zebra is set, no closure (x,y,z) may be opened without permission of DCA
-set prior to leaving or entering port during wartime, also set immediately, without orders when manning general quarters stations
- set to isolate and control fires and flooding when the ship is not at GQ
Mod Zebra ✔ - -closed when an increase in watertight integrity is needed, not req to set entire ship set to condition zebra
-normally set on the DC deck and below (2nd deck)
-all main hatches closed, scuttles left to be open will be logged as such in DC Central
-eg. at restricted maneuvering in low visibility
circle zebra ✔ - -closed during condition zebra
-may be opened during prolonged periods of GQ with permission of the CO.
-opening of fittings allows evolutions like handing out rations, sanitary facilities, etc.
- must be guarded in the event the ship is req to rapidly reset condition zebra
dog zebra ✔ - -applies fittings opening to weather spaces that are not provided with darken ship switches or light traps
-closed from sunset to sunrise when underway
william ✔ - -kept opened during all material conditions of readiness
- applies to all vital sea suctions and vital valves
-secured only when necessary to control damage and CBR contamination
circle william ✔ - -normally kept open
-secured as defense against CBR attack and the spread of damage
