filtered through a Corning No. 5840 glass filter or equivalent, which
transmits UV radiation at wavelengths between 300 and 400 nm. A Wratten
No. 2A blocking filter or equivalent should be used over the lens of the
camera. The 2A filter cuts off UV radiation below 405 nm. This filter allows
only the visible fluorescent light to reach and record on the film. The
exposures should be made in a darkened room at 1/25 s at f:8. Kodak Royal
Pan film, ASA 400, or equivalent may be used as the prime recording film,
and Polaroid type 52, ASA 400 or equivalent, may be used for quick test
prints when necessary.
An alternate approach is to use a handheld ultraviolet lamp to scan the suit
tester's clothing and face for the presence of the fluorescent powder. The
location(s) degree of contamination should be recorded on a survey form and
included in the test report.
19.1.10 Miscellaneous. Miscellaneous equipment should be used, such as craft paper
to protect walking surfaces from becoming contaminated and a box used as a
receptacle for the contaminated supplied-air suit after removal. Other items
may be used as necessary.
19.2.1 Dressing Procedure. The suit tester should don the coveralls, cloth hood,
cloth booties, and the initial pair of gloves and tape the cloth hood, cloth
booties, and gloves to the coveralls.
19.2.2 Preliminary photographs should be taken of the suit tester as follows: full
front with backs of hands turned to camera, and full back with palms of hands
turned to camera. Instant photographs also should be made of each pose to
ensure that the subject is not wearing any UV fluorescent material or
equivalent. If the alternate approach is used, the handheld ultraviolet lamp
will be used and the results recorded on a survey form.
19.2.3 A personal air sampler with AA Millipore filters installed should be fitted to
the suit tester with the sampling port as close to test subject's breathing zone
19.2.4 The suit tester then should don the supplied-air suit to be tested, exactly as
given in the supplied-air suit user's SOP. The only exception is the use of
cotton gloves instead of rubber gloves over the initial gloves. Taping of the
supplied-air suit parts should be exactly as given in the DOE contractor's
19.2.5 Powder Spraying. The suit tester should enter the test chamber and connect
the airline to the chamber fitting. The test operator should supply air to the
supplied-air suit at the minimum airflow rate specified by the DOE
contractor. The test operator should put his hands into the glove-box sleeves
and, using the spray gun (or equal device), spray UV fluorescent powder or
equivalent onto the supplied-air suit exterior. The test operator and test
subject should work together to ensure that all surfaces of the supplied-air
