That video is suitable for non-harmful dust. It's completely incorrect for infection control. Donning: He starts by cupping the front of the mask with his bar

That video is suitable for non-harmful dust.
It's completely incorrect for infection control.
Donning: He starts by cupping the front of the mask with his bare hand! This is wrong.
Doffing: He starts by cupping the front of the mask with his bare hand! This is wrong. He's touching the infected part of the mask with his bare hands.
- exolymph 7y agoNow explain viral load.
- DanBC 7y ago80% of healthcare professionals are infected from incorrect doffing procedure. Health care professionals who were using correct PPE have died because of failures in doffing procedure.
- exolymph 7y agoOkay, make the perfect the enemy of the good instead. Whatever.
- DanBC 7y agoNo. Incorrect doffing isn't merely going from "best" to "good", it's going from "best" to "actively harmful".
- cameldrv 7y agoPlease clarify that. If virus gets on my mask, most of it would have gone in my nose if there were no mask. Even if a tiny portion of it transfers to my hands while doffing, it’s safer on my hands than in my nose. I can also wash my hands after and during doffing as you say. You say that most infection in hospitals happens during doffing, but that’s precisely because the PPE is very effective at keeping the virus out of HCW’s noses. If they had leaky PPE, they would be getting infected while wearing it. It might be that doffing is 1/50 of the risk of going in unprotected, but at the viral loads in a COVID ICU, you’re that 1/50 is still a huge risk. For an average person in lower risk environments, proper doffing may be valuable at reducing risk, but I strongly suspect that just wearing a mask cuts risk a whole lot.
