authorities. They are available in three thick-
nesses: 7, 14, and 25mm. While they offer
the best resistance to chemical agent pene-
tration, they are quite difficult to use when
performing fine motor tasks. Double latex gloves
are adequate if changed frequently or until
the patient is decontaminated. They should be
changed at least every 20 minutes. Nitrile
gloves also may be used if frequently changed.
Swatch tests results by the US Army SBCCOM
(Figure 7.11) show the wide variation in perme-
ability of various types of gloves. Considera-
tion should be given to wearing two gloves
of different composition since each material
will have different characteristics with different
substances [10].
Likewise, chemical resistant, splash-proof
clothing and shoe covers are necessary in the
decontamination area. They are available from
a wide variety of manufacturers. Figure 7.12
illustrates the chemical permeability for several
different products. The Demron
™
suit [12]
offers a light weight garment for attenuation
of low and medium energy radiation expo-
sure for both first responders and medical
personnel. They come in a wide variety of styles
and are suitable for everyday wear in routine
