Alex,
Acknowledging that it is necessary to tape the top of the cloth face mask to the face under the eyes verifies that when exhaling air from inside the mask that air is forced into the eyes. Since the size of the Corona Virus organism is about 125 Nano Meters (1.25X10 E 7 meters) a large population of the organisms that are present in the breathing zone may pass through the minimal filtration provided by cloth or paper mask.
Those organisms that were not inhaled by the wearer and retained in the lungs will be exhaled. Since the exhaled air will take the path of least resistance most of those organisms will bypass the mask fabric and will be forced directly into the eyes and the mucus membranes of the eyes infecting the mask wearer.
Therefore, apart from the fogging issue, we should ask people wearing these ill-fitting face coverings to at least carry a roll of tape with them and apply tape as described every time they don the mask.
In my opinion this practice would not be inconvenient and would increase the effectiveness of this rather dubious personal protection device dramatically.

Hello,
Some researchers here say they can't wear a mask and goggles/glasses at the same time because they fog up the lenses. A piece of cloth medical tape across the top of the mask to make a seal will fix that problem. Wearing a face shield is another solution. Hope this helps.

Subject: [EXT] [DCHAS-L] PPE Excuses for Non-Compliance
Hi All
As a part of new COVID19 safety policies rolling out at the Broad Institute, we've also decided to actually enforce our PPE policy of wearing a lab coat and safety glasses when working in a lab. Part of the fall out are a lot of excuses that we're hearing from researchers on why they're not complying.
I was hoping that you all could help me brainstorm additional excuses that you all have heard from students, researchers about why they aren't wearing the appropriate PPE.
I want to be ready with responses to each of these excuses. So I thank you in advance for your time with this.
Kind regards,
Pauline Serrano
