[labnetwork] Question about cleanroom mask policies

Hi Robert,

When we returned to work after the first lock-down, we asked ourselves what to do regarding masks/face covers.
Then I did a very simple experiment to check by myself how effective is a face-cover to contain the particles we generate during normal respiration or talking. See attached summary.

Today our policy is: every user comes with his/her own mask and must put the face cover over it. This "two layers" solution is more than enough inside the clean room (plus as much distancing is possible).

Hi all.
Hope this finds everyone safe.
Now that N95s are starting to become a bit more accessible, there has been some recent discussion within our labs about whether to adopt an N95 mask policy for new users and when distancing is a challenge.
So far we have just been wearing the standard cleanroom style masks.
Just wondering what other labs have been using.

Thanks
