At Vogtle 1&2 we are in the same situation with having the same mask with the only difference between the two masks is the rubber or mesh 5-point head harness. We have challenged that with MSA. We do conduct two separate fit tests for the different harness types. What we have proposed was going to one harness type to reduce the time spent on fit testing personnel. We were wanting tor replace the rubber harness with the mesh speed harness. MSA recently confirmed that OSHA has given verbal approval for mesh harnesses on the negative pressure masks. Translation: we'll finally be able to replace all the rubber harnesses with mesh harnesses on the respirators and go down to one full-face fit test! MSA is waiting for the product Matrix from NIOSH. When we get that information back from MSA, I will be happy to share that with you.

The two style masks are made of the same rubber material and have identical face seals. The only difference between the two masks is the rubber or mesh 5-point head harness. Question: Does any other plant have a similar situation with their respiratory equipment? Do you conduct two separate fit test, because of different material in the head harness? Please respond on your style equipment and how you conduct your fit test.
