> What a tool was being used for 2 months ago isn't relevant It is very relevant. These face shields wouldn't protect anyone from airborne/aerosol pathogens or viruses. They have a very specific purpose and that isn't one of them. If you're talking about adapting construction grade shields (like used for painting, etc) for medical use -- sure. But you aren't going to use a face shield as a replacement for a face mask…
I'm certainly open to the idea that fluid mechanics are complicated and somehow air currents are going to do unhelpful things, but until I find someone with a paper on the topic I'd much rather be talking to someone wearing a face shield than not.
Plus obviously wearing a face shield will protect against self-inflicted infections from a contaminated finger.

Given that they probably would cost $1 to $5, and take almost no space to store, it wouldn't be a terrible thing for people to have a few if they want them. How many people have a $20 multi-tool that stays in a drawer somewhere? Or some bags of rice "just in case" that end up getting thrown in the trash after being forgotten about in the cabinet for 5 years? It may not be a terrible thing if some percentage of people…
It's not about the money. PPE like face shields are specifically used during procedures that involve significant bodily fluid, like intubation, which is the process of pulling or pushing a tube down a patient's esophagus. Going to to the grocery store does not require a shield. Secondly disposable medical equipment, when used properly within a healthcare environment, is extremely wasteful. For most consumable items u…
This is reusable, easy to sterilize w alcohol.

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.

What does it say? It seems to me that pretty much every society has struggled to deal with this. Perhaps because it isn't something that has many reasonable direct analogues in our collective experience? It is very easy to spot deficiencies after the fact. Much harder to spot them before.
It says that there's massive inequality?

#366The 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.

Isn't it very clearly printed on the bottle in your country? Here (I assume this is an EU regulation) it says "WARNING! Do not use together with other products. May release dangerous gases (chlorine)."
Here's a couple of typical labels in the US: https://i5.walmartimages.com/asr/2025dfde-c877-4043-b91d-978... https://i5.walmartimages.com/asr/05122787-1991-4084-869e-755...

There are almost 200 pages of EU rules and guidance in the first document [bottom of 1], and some hundreds more pages in related sections of that site.
That said, the cheap-brand bleach in my cupboard has a word-for-word translation into Danish of the English text, and a consistent layout, and there's some merit in that.

Your question was about the effectiveness of N95 masks. Hopefully I've resolved that for you. As for the effectiveness of face shields, I don't have data on that, I just said it was likely to be effective, since it blocks larger droplets from hitting your face or being inhaled. There's no luck involved, I purchased a face shield almost two months ago, although I usually just wear mask+goggles, gloves if necessary whe…
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…
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 that there is a problem with improper use, we should be teaching people how to use them instead of telling people not to wear them.
I never said wearing a mask made you immune. Seatbelts don't eliminate your risk either, but at this point only very backwards people drive a car without one.
BTW, as of today, COVID is the leading cause of death in America.

Sure. But for an equal amount of effort, raws and manpower you could get much more out of traditional manufacturing, much quicker. The product is a very simple stamp, with very simple dies with little wasted material. Perfect for traditional production methods. It's great people with machines are contributing to the effort, and empowering/informing individuals to be able to do so as well. But it's just done simpler t…
This is all great in theory, but in reality there are hundreds of thousands of these parts being delivered to hospitals right now, and they came from lots of people with lots of 3D printers at their houses, hackerspaces, and printer farms. We can definitely talk about what would have been better and more efficient, but in the meantime people need this stuff today .
It makes tons of sense for people with 3d printers to print as many as they can now because they can get them in the hands of people now. But once dedicated manufacturing comes online, that capability is going to be quickly become irrelevant.
The comment I replied to seemed to suggest individuals were printing 10s of thousands of these per day which is clearly not true. Thousands of individuals are printing a few each day which is vastly different.
