With fume hoods operating in a given room. Let‰??s say you have 8 hoods in a space that is approx. 40 ft x 40 ft (I‰??m guessing, but it‰??s not far from that). 4 hoods on two opposite outer walls. Hoods draw air towards them, I believe fresh 1x use air comes down in the middle of the rooms - so I imagine air flow is middle to edge. Does that mean that all protected people need to be towards the center of the room - facing the hoods? Do the hoods extend the 6‰?? required distance (as they are giving velocity to the air in the room)? Would face shields help here at all? I have a lot more here but I‰??ll stop at that and see where this goes. Didn‰??t mean to pirate this thread - but it‰??s about safety and reopening so just thought I‰??d add some questions.
Along these same lines, is anybody thinking about public bathrooms? That to me is one of the biggest worries when re-opening. How do you keep those spaces with dead air and lots of multi touch surfaces clean. I know you are only there for a small amount of time (no lingering allowed during pandemics) but it‰??s still worrisome. And throughout a day you may visit more than once. Just saying

> One of the difficult aspects of sheltered life during the coronavirus pandemic has been our inability to make plans. It is hard to plan when there is so much we just do not know, such as when we can next travel on a plane, when we can start seeing friends and extended family in person again, and if and when an event still on the calendar will occur. We also do not know yet when we can restart research in our laboratories.
> ...
> In developing these plans, we are thinking hard about the way the laboratories operate, how people work, how they navigate and travel to and from the buildings, etc., and we are being purposeful about designing plans that will enable research to be performed and, at the same time, ensure everyone‰??s health and well-being. As we do this, it struck me: This is the perfect time and opportunity for all PIs to take a careful look at how they operate their laboratory and to ask, is this the safest way? Might not this, the key moment when a careful process of laboratory reopening is being developed to deal with the pandemic, be the best opportunity to improve the broader culture of safety in our laboratories?
