I'm not sure I understand this argument. Are you speaking of sick people coming into the hospital during this pandemic or overall? Because I can ensure you, many hospitalizations are not due to a lack of PPE. Broken hips are not caused by a lack of PPE; myocardial infractions are not caused by a lack of wearing gloves; nor is a person falling into a diabetic comma caused by not wearing PPE. But, if you're talking abo…

People are making their own masks. There is no shortage of DIY masks. They have always been able to do that but, medical people and government leaders waited months in the USA to tell them to do that. Other countries already proved that wearing masks all the time helped protect you. Medical people are telling the public not to wear gloves. The reasons they give and examples are detached from reality. There is a video…

This. If you change your gloves whenever you would normally wash your hands, then I fail to see why cross-contamination risk would be any higher with gloves.

My question was not about the effectiveness of N95 masks in a vacuum, it was correcting your assertion that the people that have died in the hospital, did so because they didn't wear N95 masks. It is possible to wear an N95 mask incorrectly, or to contaminate yourself during the putting on/taking off process. The idea that N95 masks inherently make you immune to exposure is ridiculous. The people that died in the hos…

I think it's pretty simple. If you don't get the virus, you don't go to the hospital or die in the hospital. If you wear an N95 mask, according to the best data available, you have a 91% smaller chance of catching the virus. Yes, it's possible to make mistakes donning and duffing. However, that same meta-analysis also showed a large benefit for community use of masks, so actual use, not perfect use. To the extent tha…

Stopped reading after this. It's not.

People were told face masks don't work by the officials. This actively harmful lie was propagated since they wanted to save the PPE for health care workers. The problem with this approach is that one asymptotic/mild cashier can undo the work of a thousand health care workers.

It also fostered distrust among anyone able to see the elementary contradictions in their arguments.

The Czech 3D Printer company Prusa has been on it for a while: https://www.prusa3d.com/covid19/ and they have been open-sourcing the design. You can print it on a 3D printer. Based on that design (and others) makers in Germany have started organizing, so that people can either request shields or supply shields. Organized on Slack and into local distribution hubs. We hace started sharing supplies and even got discount…

What is the point of 3d printing something that clearly needs to be mass-produced in great quantities? Maybe it "feels good", but it's just too slow. I'm honestly not sure why people don't just use plastic food wrap as a cheap improvised alternative for face shields. It's lightweight, readily available, disposable, fits over any attire and does not restrict visibility.

These kinds of parts can actually be mass produced. You could probably make 3500 face shields in less than a week with 10 printers. The mass produced Prusa i3 printers actually use quite a few 3D printed parts, and they made over a hundred thousand.

It is a bit sad that so many people miss or forget these important lessons in HS chemistry :P

Wasn't even told that about those things in HS chemistry in my time in my country, not sure why - considered too dangerous knowledge by educators? Only found out about it on 4chan and gasped on how easily we could have accidentally injured ourselves while cleaning our dorm bathroom.

I learned about it through The Anarchist Cookbook. They don't teach you in high school not to transport gasoline in a styrofoam container.

For what, though? And I'm 100% being honest here, what is the specific situation you are envisioning that requires a face shield in your home? In a medical setting, shields are typically used in conjunction with eye goggles and respirators when performing procedures that have a tendency to cause or be around splashing body fluids. Outside of someone sneezing or spitting on you directly, I can't think of an analogous…

You store it in your home, then wear it when you go line up for food in case the person next to you turns and coughs or sneezes.

Imagine being at the gas pump, and the person next to you sprays gasoline at you. A faceshield might keep your face from getting soaking wet, but if you smell the fumes, it hasn't prevented exposure to your sinuses or lungs.

Except you can't smell a virus.

Touching one's mask is infinitely better than the alternative of touching one's face, and in the case of a non-symptomatic individual wearing a mask to reduce outbound infectious particles has no bearing at all. The whole 'masks are too hard to use' thing was a horror perpetrated by gov't officials afraid of private individuals hoarding masks.

> Touching one's mask is infinitely better than the alternative of touching one's face That depends entirely on if there is a viral build up on the outside of the mask. Discouraging people from using N95 masks was specifically to avoid the private hoarding of masks. But discouraging use of other masks (and N95) by the public is because they do not protect you if they are used wrong. When any air passed around a mask,…

> Unfortunately, any help that wearing a mask would offer to the wearer is often countered by the false sense of security that they bring

Today's cars are extremely safe. Are you saying that they actually increase accidents because it gives people false sense of security? Should we remove some of the protections, for example the seat belt, because that would make people drive more carefully?

Because best data to date is that sterilization procedures damage the mask in ways that render it unsafe. When someone comes up with data finding a safe way to do so, the masks won’t go in the trash. In the meantime, I’d you have the masks to spare, you -should- be using them safely. Masks are pointless if you use them in a way that will get you sick.

This is untrue. Stanford Medicine released a study around March 22. The TLDR is 70°C heat for 30 mins. Avoid alcohol, it kills the static charge in the mask fibres. https://m.box.com/shared_item/https%3A%2F%2Fstanfordmedicine...

No, THAT’s untrue. Look at your own link. You can sterilize the mask to preserve its filtration ability, but no one has shown it maintains fit. A poorly fit N95 is no protection at all, which is why hc workers get formally fit tested when starting a new gig. Which is why That link makes “no one knows what it does to fit” one of its top line bulletpoints.

> manufacturing in the US and China Mixed feelings about this. What happened to the reports that Apple suppliers were essentially using slave labour to build their products in China? I didn't see any response at all from them - do they care? https://www.businessinsider.com/apple-forced-uighur-labor-ip...

I'd be more concerned about Chinese suppliers who have privately said they would supply faulty equipment related to corona virus to the US.

Can you provide a source for that? It smells of a rumour people might spread to sow mistrust.
