1/ If your school is closed and trying to reopen (or if you& #39;re open and want to keep it that way), some resources:

2/ Knowing when to open is hard, too. We recommend basing it on metrics of community spread.

3/ Not sure what to look for at your school?

Here are 20Q every parent should ask (w/ @CorsIAQ @etgall @KimberlyClev +) https://twitter.com/i/status/1286655120609103873">https://twitter.com/i/status/...

4/ Not sure how much ventilation you should be targeting for your school?

We teamed with @ShellyMBoulder to come up with some targets for school classrooms

5/ Not sure how to achieve these air exchange rates? There are a couple of good, low-cost options.

One good one is opening the windows

6/ You can also achieve this through the use of portable air cleaners.

op-ed with @CorsIAQ on this approach here https://www.washingtonpost.com/opinions/2020/07/27/we-can-must-reopen-schools-heres-how/">https://www.washingtonpost.com/opinions/...

7/ Not sure how portable air cleaners work? Our team wrote up a short technical (but not too technical) white paper.

8/ But you don& #39;t have to read the technical report. We worked with @ShellyMBoulder to build a simple tool to help you pick the right portable air cleaner for your classroom #gid=1882881703">https://docs.google.com/spreadsheets/d/1NEhk1IEdbEi_b3wa6gI_zNs8uBJjlSS-86d4b7bW098/edit #gid=1882881703">https://docs.google.com/spreadshe...

9/ Think it can& #39;t be done?

I had the pleasure of presenting to @MayorSiddiqui and Cambridge Public Schools on Friday and learned that they assessed ventilation in classrooms using our guide, and are using portable air cleaners (w/ HEPA), too https://abs.twimg.com/emoji/v2/... draggable="false" alt="👏" title="Applaus-Zeichen" aria-label="Emoji: Applaus-Zeichen">https://abs.twimg.com/emoji/v2/... draggable="false" alt="👏" title="Applaus-Zeichen" aria-label="Emoji: Applaus-Zeichen">https://abs.twimg.com/emoji/v2/... draggable="false" alt="👏" title="Applaus-Zeichen" aria-label="Emoji: Applaus-Zeichen">

10/ Many other schools also doing this.

Here is one using a balometer to measure ventilation rates.

Not sure what this is, or how to do it? Our guide breaks this down into 5 steps: https://schools.forhealth.org/ventilation-guide/">https://schools.forhealth.org/ventilati...

11/ Ventilation and filtration are one component of a larger risk reduction strategy.

Masks are a must!

What about buses? music? recess? sports?

Our report covers all of this: https://schools.forhealth.org/risk-reduction-strategies-for-reopening-schools/healthy-activities/">https://schools.forhealth.org/risk-redu...

12/ Here& #39;s a simple graphic with some key tips to stay #SchoolSMART

S--> Stay home when sick
M--> Mask up
A--> Air purifier in every room
R--> Refresh indoor air
T--> Temporary classrooms
