Mounting the UPAS
The UPAS may be used as either a personal breathing zone sampler or it may be
mounted for stationary site sampling.
Mounting the UPAS for Personal Breathing Zone Sampling
In order to collect a good personal air sample, the participant should wear the
UPAS as near as possible to the participant’s personal breathing zone. By placing
the UPAS Sampler in the participant’s breathing zone, it samples the same air as
the participant is breathing.
Personal Breathing Zone is defined as the area immediately surrounding a
person’s nose and mouth where the majority of air is drawn into their lungs. This
zone is the area monitored by the UPAS to aide in determining the presence of
airborne contaminants.
Several possible solutions exist to fit the UPAS to participants:
– A lanyard suspending the UPAS from the participants neck. See Figure 1
on page 5 for the location of the lanyard hole.
– An adjustable harness which holds the UPAS firmly against the partici-
pant’s body over the collar bone.
– An industry safety vest with attachment points for proper breathing zone
mounting.
When fitting the UPAS to a participant, adhere to the following guidelines:
– Always follow the protocol of the agency or organization sponsoring the
air test.
– The UPAS must always be worn outside of clothing.
– Make sure the front of the UPAS device faces outward and does not get
covered or blocked by clothing or other items during the personal sam-
pling period.
– Participants should remove the sampler when they sleep, bathe, smoke,
etc.
– The UPAS Sampler must be shielded from rain and all moisture at all
times.
