should be incorporated into the test report.
18.2.3 A device to hold the sampling tubes in the breathing zone of the supplied-air
helmet, while not affecting the normal operation of the suit, should be used.
The device is only required for testing oxygen and carbon dioxide
concentrations, and if desired, may be eliminated during other evaluations.

Test Procedure
18.3.1 Test Subjects. This test should be run on each of the three suit testers. The
suit testers' physical sizes should be as listed in Section 11.3.1.
18.3.2 The suit tester should don the supplied-air suit in accordance with the
instructions provided by the DOE contractor. Taping or any relevant
accessories, such as a hardhat or body harness, should be used, and the
supplied-air suit should be supplied with the minimum airflow rate, as
specified by the DOE contractor. The suit tester should stand with his arms
by his sides. The test operator should stop the flow of air, and the suit tester
should begin to remove the supplied-air suit as quickly as possible.
18.3.3 The test will be terminated when any of the following conditions occurs:
The suit tester escapes from the suit. The suit tester should be considered
to have "escaped" when his head is outside of the supplied-air suit. The
test operator should record the time necessary to escape.
The oxygen concentration reaches 16 percent.
The carbon dioxide concentration reaches 5 percent.
18.3.4 The test operator should record the time at which the test was terminated.

Contaminated Supplied-Air Suit Removal Test
19.1
Test Equipment
19.1.1 The degree of contamination incurred when removing a supplied-air suit
following the DOE contractors' normal removal procedures is evaluated
using a fluorescing powder. A suit tester dons non-ultraviolet fluorescing
protective clothing consisting of coveralls, cloth hood, cloth booties, and
gloves. "Before" pictures are taken with ultraviolet (UV) lights to ensure that
there is no UV fluorescing material at the start of the test. The suit tester then
dons the supplied-air suit to be tested, in accordance with instructions
provided by the DOE contractor. The suit tester enters a special test chamber
wearing the supplied-air suit operated at the minimum airflow rate specified
for the supplied-air suit under test. The test operator, reaching through glove-
box sleeves in the side of the chamber, sprays a coating of dry, UV
