Good Morning Ladies and Gentlemen,
As you may know, just as ACS/DCHAS operate this important dialogue on various topics of timely interest, so does the American Industrial Hygiene Association (AIHA) operate "catalyst/AIHA" as open discussion for its community.
For those of you who are not members of the AIHA, Jeremy DeWitt, CIH (DuPont Protection Technologies, Midlothian, VA) just posted the following question with an attached reference.
"I am wanting the objective feedback from the (AIHA) community about the Harvard study citing that 3ft is adequate space for social distance in school."
He states, "This study (see attached below) is currently being used as justification for returning children to school in the central Virginia region"
And further states, "The effectiveness seems to be contingent upon effective mask usage. This does not seem to be a realistic layer of protection when dealing with elementary age children."
Any comments you have would be welcome here for DCHAS members to review.
Those of you who are AIHA members might want to comment on "catalyst/AIHA" as well. David M. Lipton, CIH from the NC Division of Public Health (Raleigh, NC) just posted the first reply 30 minutes ago.
Also, in keeping with our current dialogue on "Eyewear," do scroll down to the section of the study which discusses use of protective eyewear to help reduce exposure which is based upon mostly SARs and MERs data. Will non-vented/gas-tight Z877.1+ D3/D4/D5 be the best solution for not only frontline heathcare workers but also the general public?
Be Safe and Stay Well!
All My Best,
