Summary

[edit]
Description

The 3M 8511 mask on participants F-28 and F-68.

In both cases, the material of the respirator makes contact with the wearers’ skin close to the tip of the chin, leaving what appears to be a visible gap. However, there was enough subcutaneous fat to consistently seal the mask in participant F-28, achieving the maximum score of 200+ for all tests. In the case of F-68, there was not enough subcutaneous fat to consistently ensure a seal between the respirator and the skin, leading to consistently low fit testing results.
