It would be helpful if you as a requestor of information were to more
carefully read the message triggering your request. The phrase you seek
support for is not a statement made by Ralph. Ralph was quoting part of a
suggestion that I made.
At this date and time I have little interest in typing out, once again, the
basis for that. I would merely point out that in the midst of a crisis,
which this is, we sometimes do not have the luxury of waiting for rigorous,
quantitative scientific results on all questions but must apply our best
current understanding of the mechanisms of filtration and particle emission
and distribution.

source(s) attribute this benefit. What are the contraindications for mask
wear? What sort of sequelae might be expected from the blockage of normal
respiration? Are you prescribing this as a medically approved device? Are
you a medical doctor?

assertion that a face mask provides substantial protection to the wearer...
I suggest it would be very useful to explain that, while a face covering may
provide some slight protection to the wearer, its primary function and use
is to significantly reduce viral emissions from a wearer who is infected but
asymptomatic.

will be too complicated be shared in that setting. (This is primarily based
on experiences discussing indoor air quality issues with a heterogeneous
population of building occupants.)
It's their annual blood borne pathogen training class, but we will clearly
need to discuss the issue you raise as well. This is a setting where I feel
comfortable doing this. This is because, I have a history with the group, I
have some idea of what their questions will be ahead of time, and we will
have time for extended questions and answers.
