e. Monitoring Port. The monitoring port allows the chemical agent monitor (CAM)
detector inlet to be inserted into the outer compartment by a CAM operator located in the inner
compartment. This allows the CAM operator to determine if there is agent vapor in the outer
compartment. With a negative reading in both the G and H mode (about 10 seconds each), the
operator may determine that a shorter or longer dwell period is required. A second CAM check
for sorbed vapor can then be performed in the inner or second stage compartment.
f. Caulking. Caulking should be applied to all joints to limit uncontrolled air leakage.
g. Paint. Painting the interior and exterior surfaces with epoxy paint is required to
minimize the sorption of liquid and vapor agent.
h. Instructional Signs. Basic personnel processing instructions should be provided on the
outer and inner doors.
i. Clothing Chute or Trash Bag Container. A clothing chute allows contaminated clothing
to be removed from the airlock and discarded outdoors without re-exposure of personnel to the
contaminated atmosphere. As an alternative, plastic trash bags can be placed in the airlock so that
personnel can seal clothing in the bag after removal. The bag is then removed by the next group
entering the airlock. If a clothing chute is not provided, a trash bag container should be provided.
