Controlled and ADS User IDs can be viewed via the EPD’s LCD display. Detailed
instructions to display User IDs are given in Section 3.5.
2.1.6 Wearing
an
EPD
The EPD should be worn under the direction of the health physicist. For most
operating conditions it is recommended that the EPD be worn on the outside of
any protective clothing (see Figure 2.5). Note that the button should be facing
outwards.
Wearing the EPD on the outside of protective clothing has the major advantage
that the user can read the EPD’s LCD display and operate the button as required.
Typically, the EPD should be worn on the chest or the waist. The type of outer
protective clothing will determine how the EPD is attached (i.e. the EPD clip or
lanyard). For example, if the protective clothing has no breast pocket (or the use
of a belt is prohibited) the lanyard may be the most practical method of wearing the
EPD.
Figure 2.5 - Wearing An EPD
Note
: The lanyard cannot be fitted without first removing the lanyard plate (see
Section 6.3.1).
When the EPD is worn on the outside of protective clothing, to minimise the risk of
contamination of the EPD, consideration should be given to wearing the EPD in a
suitably-sealed plastic bag.
