Safety Knights

We do both fit testing and medical clearance in house, and I do fit testing as a consultant to others.

There is no certification for fit testing, the person doing the fit testing simply needs to be competent (although OSHA doesn't even say that). Obviously for the medical clearance, you would need a physician or licensed healthcare professional.

I've always done it in-house. You have to be qualified to perform the fit testing, not necessarily "certified" (but that helps to justify your qualification).

As Tim mentioned, you have to have certain credentials to do the medical evaluations.

We do a mix of both. We have a full time occ health nurse and part time doctor doing most of the medical clearances but also have a contract with a provider just in case. For fit testing a contractor comes on site during one of our quarterly ERT trainings to get everyone at once. We also have a machine on site to catch any stragglers or for new hires.

For the fit test machine I had to get some training on because I was only used to the port-a-count. The machine is an OHD that uses controlled negative pressure.

We do fit testing in-house but use an occupational medicine provider for the medical clearance and any additional hazard-specific medical approvals.

We do both. Our nurse takes care of the medical clearance and fit testing
