Adjust the distance of the Power Unit to
the back of the neck to suit the type of
work to be undertaken.
For example, if the job involves rapid
movement (e.g., running up stairs) it
may be preferable to set the Power Unit
more snugly against the neck. If looking
up a lot, it may be more comfortable to
wear the Power Unit more loosely by
setting further back from the neck.
To move the Power Unit toward the
neck, steady the mask with one hand
and press on the back of the Power Unit
with the other. Clicking will be heard as
the adjust mechanism tightens.
To move the Power Unit away from the
neck, press and hold the Adjust Buttons
on both sides and push Power Unit away
from neck.
Ensure adjustments are symmetrical.
10. Entering and Exiting the Contaminated Area
Prior to entering the contaminated area
1. Don as per section 8 or 9 depending on mask type.
2. Ensure Seal Check has been completed.
3. Ensure the Power Unit is breath responsive.
4. Ensure no alarm is sounding.
5. Noisy Environment. Apply special precautions set out in Section 11. Working in Noisy Environments.
In the contaminated area
1. Do not remove the CleanSpace Respirator until you have vacated the contaminated area unless you have pressing
health reasons to do so (for instance you are experiencing dizziness and believe removing the respirator while leaving
the contaminated area may help).
2. Leave the contaminated area immediately if any of the following conditions occur:
a. Any part of the system is damaged
b. Airflow into the mask decreases or stops
c. The battery or filter alarms are triggered (even if only the audible or only the visible alarm triggers)
d. Breathing becomes difficult
e. Dizziness or impaired vision
f. Smell or taste of contaminants
g. Face, eyes, nose or mouth become irritated
h. It is suspected that the concentration of contaminants may have reached levels at which the CleanSpace
Respirator may no longer provide adequate protection.
Exiting the contaminated area
Specific exiting and decontamination procedures should be part of the workplace respiratory protection program. Follow
those procedures, together with the instructions below when removing the CleanSpace Respirator.
