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
At times voice communications will be difficult due to high noise level.
a. Cab Crew Tasks
Locate MOPP gear and put on full chemically protective clothing and masks.
Close ECV, outside TALP and outside ambulatory airlock doors.
Circuit breaker on LMS power panel (rear, driver side) must be ON for TQG or equivalent

Continuing start up or operation without correcting problem can damage system.
Monitor gages and hydraulic indicators to verify that all systems are operational.
Ensure that fastener hook and fastener loop are engaged properly on outer ambulatory airlock
Ensure that TALP tunnel fabric is properly latched to TALP airlock door.
Verify that DCS flaps are rolled down and secured or that connectors are in place and secured.
Open vent holes on outer TALP and ambulatory airlock doors by adjusting or pulling back
fastener hook and fastener loop cover so that at least two holes are visible.
Communicate with LMS crew to determine if adjustments to outer TALP, ambulatory airlock
door and DCS connector vents are required.
b. LMS Crew Tasks
