where radiological work is performed.
White plastic PVC pipes and junctions are used to create a
support structure for a heavyweight clear plastic
contamination containment (glove bag). The glove bag
measures approximately 2 ft wide x 2 ft high x 3 ft long.
The glove bag has four glove ports, which allow the
installation of four sets of heavy rubber gloves for
Radiological Workers #1 and #2. The bag is suspended
from the PVC pipes by "bungee" cords.
Inside the glove bag is a valve, with two shutoff valves
installed on both sides. The valves are installed on PVC
pipe, which penetrates the glove bag. The penetrations are
taped, to ensure a good seal.
Normally a polyethylene (poly) bottle would be connected
to the glove bag, to collect any liquid released inside the
bag. In this exercise, the poly bottle is intentionally not
installed.
Radiological rope barrier and standard signs (which
intentionally contain improper wording or incorrect color
combinations) surround the posted area, which measures
about 15 ft x 15 ft square. One exit, with step-off pad, is
provided, through which the actors enter the area.
Directly beneath the glove bag is a simulated area of high
radiation called a "hot spot," with a standard label filled-in
to indicate the dose rate. A yellow lead blanket is provided
to cover (shield) the "hot spot."
The simulated job, which is controlled by a Radiological
Work Permit (RWP), is valve removal by Radiological
Workers #1 and #2, supported by a Radiological Control
(DOE RadCon) Technician, a Quality Inspector, and a
DOE Representative.
