We use cloth face masks along with face shields and social distancing.


In order to accommodate safe practices we alternate personnel every two weeks  half on half off.
6 feet apart.

Don't know how much more can be done. Any suggestions?

And how will splash goggles interface with face masks so that both are effective without one interfering with the other's function?

EXTERNAL Exercise Caution

Good morning,

 

What is the latest about wearing cloth mask while doing lab work? Does anyone know of a good article? Pros and cons.

 

Regards,  yamy

> In fact, just compiling a list of coronavirus-related issues that should be addressed  would be valuable. 

I'll throw one in: An issue I am concerned about in regard to reopening any public area is the cloth mask protocol. Cloth masks are community health measures rather than personal safety measures, so I would be reluctant to impose OSHA style expectations on the use of cloth masks by the public. On the other hand, I can imagine that these masks are likely to become reservoirs for many contaminants beyond the Covid virus.

I think that we face a major challenge in maintaining the quality of the cloth masks if we ask people to wear them in public areas while relying on the wearers to maintain them. I suspect that professional laundry services will be required to assure co-workers and the community that the masks are being appropriately cleaned.

A related question is: Are labs public areas? Few academic labs I have seen have security protocols that control who enters them and it will take a significant change in both protocol and culture in change this situation.

Thanks for asking an interesting question.

- Ralph
