I’ve seen a few posts on the difficulties with donning & doffing PPE correctly with COVID19. Don’t forget the CDC Trained Observer program is aimed at high-risk PPE situations. Details here: https://www.cdc.gov/vhf/ebola/hcp/ppe-training/trained-observer/observer_01.html
We used this program when I worked in the Middle East to train many staff as trained observers, for both MERS-CoV and Ebola. It works. Trained observers give everyone a second set of trained eyes on them as they don & doff safely.
My own Powerpoint version of the program is available here to use, re-use, modify, and share for free (CC0 – public domain licence): https://drive.google.com/file/d/1e-YavM7-Zi-W9De52MHw5AKrSsOsjK5Q/view
Sample PPE checklists as MS Word documents, to use, re-use, modify, and share for free (again CC0 – public domain licence) are available here: https://drive.google.com/file/d/1ch6sNacG9w_wDl__WJGmQbCKVQUjbhl1/view
