(7)
Loosen two threaded knobs (5) on inner TALP airlock door (2).
To prevent death or injury to personnel from contamination, ensure NBC SHELTER
PRESSURE gage reads at least 0.5 iwg.
(8)
Open holes on vents (8) of door (2) by pulling back fastener hook and fastener loop cover.
(9)
Locate inner ambulatory airlock door in LMS (1, figure 2-41).
(10) To install inner ambulatory airlock door (1), LMS crew member no. 1 takes position inside
ambulatory airlock (2).
(11) LMS crew member no. 2 stands inside ABS (3) and positions door (1) with timer (4) facing into
ambulatory airlock (2).
(12) LMS crew member no. 2 places metal tab (5) on bottom of door (1) into fabric loop (6) on bottom
of door opening (7), and positions and supports door (1) for assembly from inside ABS (3).
(13) LMS crew member no. 2 starts fitting reinforced cable on door opening (7) around frame of door
(1) from bottom up.
(14) LMS crew member no. 2 carefully secures fastener hook and fastener loop tape on each side of
door (1) working from bottom of door (1) to top until secured.
(15) LMS crew member no. 1 engages five spring clips (8) on door (1) to secure frame of door (1) to
ambulatory airlock (2).
(16) LMS crew no. 1 enters ABS (3) through door (1), closes it, and opens holes on adjustable vent (9)
of the door (1) by pulling back fastener hook and fastener loop cover until NBC SHELTER
PRESSURE gage (located on rear control panel in LMS) reads 0.5 iwg.
(17) LMS crew waits for cab crew to complete installation of outer TALP airlock door.
(18) Remove airlock pressure gage (1, figure 2-42) from rear of LMS. Install gage between
ambulatory and TALP doors using two fastener hook and fastener loop straps. Pass straps
through D-rings on airlock wall and bring to front of gages. Pass straps through slots and attach
fastener hook and fastener loop.
(19) Attach three air lines: ABS inlet line (2) to quick disconnect at gage (1) input (top center), TALP
airlock line (3) to quick disconnect at litter gage input, and ambulatory airlock line (4) to quick
disconnect at ambulatory gage input.
(20) Ensure airlock pressure gage (1) is level (front to back) and not tilted.
NOTE
Light set and medical chests are stowed on HMT.
NBC recirculation filters are stowed in LMS.
(21) After cab crew signals that outer TALP door is installed, begin purging airlock.
(22) Carefully open TALP door (2) and insert TALP rails (6) into entrance way. Slide slotted plate (7)
on TALP rails (6) into place between backing plate and inner TALP airlock door threaded knobs
(5). Do not tighten knobs (5) until outer TALP door is installed.
(23) Outer TALP airlock door vents should be adjusted to achieve a pressure of 0.3 iwg within TALP
airlock. Communicate with cab crew to have them adjust outer TALP airlock door vents as
necessary. Allow TALP airlock to purge for approximately three minutes. Using CAM, open side
zipper (9, figure 2-40) and check if airlock has purged sufficiently. If contamination is present,
remove CAM and close zipper (9). Allow another minute or so to pass before performing another
CAM check. Continue to check until no presence of contamination is detected.
