“They passed their mask fit test. Why are we checking again?”

Watch MaskFit+ Specialist, Mario, explain why knowing how to perform a user seal check matters beyond the testing session.

For employers and H&S teams: if an employee reports a failed seal check, would their supervisor know what to do next?

“But their mask fit-test certificate is still valid!” 😳
That doesn’t mean their mask or respirator is sealing properly today.

A loose strap, poorly positioned nosepiece or even a change in facial dimensions can affect the seal.

That’s why fit testing and user seal checks serve two very different purposes.

And why employers need to make sure employees AND supervisors understand both.

HOW did your employees end up booked for the WRONG fit test?

It usually starts with choosing qualitative or quantitative testing before confirming the hazard, protection level and mask or respirator. Here’s how to get the order right.

That box of masks in storage may not be ready for your next fit-testing session.
Watch what employers need to check and tell us: when did you last review your equipment?

“It’s still an N95. What’s the big deal?”
“N95” is a classification, not a complete product identifier. If purchasing records, inventory labels and fit-test records do not clearly identify the approved product, an employee could unknowingly receive a different mask.

Reusable respirators add even more decisions involving facepieces, filters, cartridges, cleaning, maintenance and replacement.

Read the article to learn what employers should standardize so the equipment issued after mask or respirator fit testing matches the equipment documented during it.
