PRE-FIRE PLAN:
Steering Room
2-94-0
Contents of Space Hydraulic steering pumps, hydraulic oil, electric motors, vent fans. Adjacent Spaces Forward: Above: Below, Sides and Aft: Forward:
Tunnel Weather deck Ballast tanks 3-94-1 & 2 Ballast tanks 4-86-1 & 2, tunnel 2-86-0, array leakage tank 3-92-2
Manual Closures Escape scuttles 1-97-1 & 2, WTD 2-94-0, intake vent 1-92-1, exhaust vents 1-90-2 and 1-91-2. Power Shutoffs Secure ventilation panel P412, switch #2 at 2-72-0. Secure power to steering gear panel EP408 at EDG switchboard 01-10-2 and at panel P413. Secure power to panel at MCSC panel 2-54-3. Secure light panel L128-6 at 2-61-2 next to aft MSCS WTD. Fire Fighting Gear Fire stations #11 & #10 1-72-1 & 2 (extra length of hose required on starboard side), #16 2-82-0, AFFF nozzles & foam, CO2 fire extinguisher in DC Locker. Class of Fire Possible class "B" fire from hydraulic oils. Possible class "C" fire from electric motors. Two classes may combine. Fire Fighting Secure power, make manual closures. For a known class "C" fire, enter from tunnel with CO2 extinguisher wearing SCBA. Apply CO2 to source of fire. For class "B" or unknown fire, lead out hoses from stations #11 & #10 1-72-1 & 2. Rig AFFF nozzle to starboard hose, install fog applicator on port hose. Lead both hoses to port scuttle, cool down decks with water from both hoses. Cool scuttle, open scuttle and immediately discharge AFFF into space through water curtain from fog applicator, cooling decks while changing foam drums, reseal scuttle, set re-flash watch. Cleanup De-water space with bilge pump or submersible electric pump. Two lengths of hard rubber suction hose with a foot valve may be needed to reach the space as the nearest submersible pump power outlet is located aft of the main deck DC locker. Hazards Combination of AFFF and hydraulic oil will make deck of space extremely slippery for cleanup. Operations Assume the total loss of the steering systems. Rig for chain fall steering. Evacuation To evacuate space exit: • There are to Emergency Escape Haches in the overhead at (2-99-2) and (2-99-1`). • Forward to Manual Watertight Door (3-94-0) into tunnel access that leads to motor room
