I addressed the long-term mask wearing with management last week.
We were discussing how we were going to proceed when we go back to work. They were talking about n95 masks.
I brought up that it's, often, 100-120 degrees and humid on the floor. The masks are fine for people in the pulpits who are sitting in chairs a d pushing buttons but the masks won't last 30 minutes on the floor. Even if they do it'll be very difficult to breathe in them, and they'll fog our safety glasses, in those conditions.
We have face shields that attach to our hard hats that cover our entire faces. They're not as effective as masks in normal conditions but I think that it's a good compromise.
