Do you mean who would do the test or who would have it done?I'm still trying to figure out who would fit test a paper mask?
We used to get fit tested at work, but they eventually stopped doing it. I have no idea why it was stopped.
An outside company would come in once a year and do a pulmonary test, you had to take a deep breath and exhale as hard as possible in to a machine hooked to a computer. I think it measured your lung capacity.
After that test they would fit you with a N95 mask, instruct you how to fit it properly and then spray a saccharine mist. If you could smell the nasty sweet smell you didn't have a good seal, and they would instruct you how to readjust the mask.
I have no idea why they used saccharine other than the nasty smell and I have no idea what size the particles/molecules of saccharine.
Of course if you had facial hair or gross facial deformities you would never get a proper seal. And yes you could get a seal good enough to not smell the saccharine.
