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.
