> >It would be helpful if AIHA or ACS could release a statement on the use of cloth masks in laboratories.

The problem I see with this relates to most of the issues you mention: the definition of "laboratories" is so broad that developing a statement beyond the broad advice that CDC produces is a significant challenge. Even within a chemistry department, organic labs, analytic labs and teaching labs present three very different risk scenarios and people are likely to be moving seamlessly among them. I've had enough experience with trying to develop a glove usage policy for a diverse lab setting to wonder if we'll get much further with masks. This is particularly true since, as you point out, the purpose of cloth masks is unclear, both to safety professionals and the public.

There is also the down side of cloth masks as with any PPE, to consider:
1. fogging of eyewear, whether prescription or safety
2. developing and maintaining an awareness of the importance of proper fit
3. interference with verbal clear communication with labmates
4. identifying appropriate decontamination and reuse protocols for the masks after use (someone compared a used mask to a used diaper, without the color indicator to indicate a contamination problem)

Thanks for helping us to think through this challenge.
