21. Periodic Maintenance & Checking
Recalibration
WARNING
You must recalibrate the internal pressure sensor any time that your CleanSpace HALO is
exposed to changes in temperature of more than 36°F (20°C). It is best practice to also re-
calibrate if the unit has been in storage, particularly if the storage temperature is not known.
See Section 13 for how to calibrate your respirator.
22. Performing a Quantitative Fit Test
PERFORMING A QUANTITATIVE FIT TEST WITH A HALF MASK
To carry out a quantitative fit test with a Half Mask your specialist mask fitter will require PAF-0025 PortaCount
Adaptor and the accompanying S005-7174 Quantitative Fit Test Instructions . The PortaCount Adaptor is an
accessory that fits between the mask and the exhalation valve and allows the air in the mask to be sampled. It
comes with detailed instructions on how to carry out a quantitative fit test.
PERFORMING A QUANTITATIVE FIT TEST WITH A FULL FACE MASK
Mask fitting must be carried out by a specialist / designated mask fitter . A fit test must be performed during
initial selection of a respirator, or whenever the user’s face changes shape (for instance due to weight gain or loss)
and at least annually. The test is performed using a machine that compares the concentration of particles in the
mask with that in the surrounding atmosphere. One example is the PortaCount Respiratory Fit Tester, made by TSI
Incorporated.
CleanSpace Full Face Masks come with a built-in sampling port and a sampling ball accessory which make it quick
and easy to carry out a fit test.
To set up for the test, do the following.
Firstly, we recommend you remove the inner mask as that makes
access easier.
With the mask off your face, pull
the orange plug from the Sensing
Ball socket. Locate the Sensing Ball which
was supplied with your mask. Fit the Sensing Ball. Push it all the way in.
Note that there are small fins on the stem
of the ball to ensure the correct
orientation.
