The Seal Check Cap must be removed before entering the contaminated area. The cap blocks the exhalation valve, making it
more difficult for your exhaled air to be expelled from the mask. Failure to remove the cap will lead to a buildup of carbon
dioxide in the mask, which could result in headache or dizziness.
Never leave the Cap in place for more than 2 minutes!
9. Using the CleanSpace Respirator with Full Face Mask
MASK FITTING –FULL FACE MASK
Determine the correct mask size and achieve a good fit prior to using the CleanSpace Respirator.
Mask fitting must be carried out by a specialist / designated mask fitter. The fit must be confirmed by a quantitative fit test.
To carry out a quantitative fit test the specialist / designated mask fitter will require the S005-7174 Quantitative Fit Test
Instructions.
No PAPR can fully protect you if you are not clean shaven. CleanSpace Respirator is not suitable for users with facial hair.
MASK SELECTION GUIDELINES
No set of guidelines can ensure a good fit. Fit must be confirmed with a quantitative fit test.
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.
