2.24.2.11 Static Operation With Internal Power - Switchover From Non-NBC To NBC Conditions.
During NBC mode of operation, ensure EPG switch, power panel, circuit breakers (OUTLET
ASSY, HEAT/COOL, NBC/VENT, INSTM CONT, LTG/INTERCOM) and NBC fan remain
ON. ESS MODE selector switch must be on VENT, HEAT or COOL.
To prevent injury to ears, hearing protection is required.
Do not hit LMS or ABS windows. Windows may crack or break.
NOTE
To reach over pressure in ABS as quickly as possible and to prevent contamination,
communications between LMS crew and cab crew are essential. A method of communication
should be established as early as possible (possibly prior to mission). This can take the form
of voice communications, hand signals, field phones if available, or a combination of any of
these methods.
At times voice communications will be difficult due to high noise level.
a. Cab Crew Tasks
(1)
Locate MOPP gear and put on full chemically protective clothing and masks.
(2)
Ensure that ECV engine is running with EPG switch set to ON.
If any engine indicators come on during system start up or operation, use over rides as
necessary and proceed to troubleshooting (Chapter 3, Section II) to take corrective action.
Continuing start up or operation without correcting problem can damage system.
(3)
Monitor gages and hydraulic indicators to verify that all systems are operational.
(4)
Close ECV, outside TALP and outside ambulatory airlock doors.
(5)
Ensure that fastener hook and fastener loop are engaged properly on outer ambulatory airlock
door.
(6)
Ensure that TALP tunnel fabric is properly latched to outer TALP airlock door.
(7)
Verify that connectors are secured.
(8)
Open vent holes on outer TALP airlock door by adjusting or pulling back fastener hook and
fastener loop cover so that at least one hole is visible.
(9)
Communicate with LMS crew to determine if adjustments to outer TALP door vents and, if
applicable, DCS connector vents are required.
