Have you seen James Lyons Weiler's article on QUATS

https://jameslyonsweiler.com/2020/10/19/quats-in-schools-and-in-your-home/

One of the many reasons I refuse to fly.

There's an indoor playground I like taking my preschooler to in the oppressive Texan summer. On their Facebook page they showed how "safe" they were being by having a grown man in a full hazmat suit spraying some unnamed cleaning chemical on the playground

It did not go as they planned.

They have since switched to a hydrogen peroxide solution.

I am way more scared of the cleaning chemicals used in gym or church nurseries than any infectious disease. UV lights would be a huge improvement.

This is already a thing. Like, they have robots already that will go into hospitals and flash high-powered UV lights in empty rooms to disinfect surfaces. Also, there has been some research on an intravenous UV light that could be used as a treatment for people with certain diseases...I think that's what Trump might have been referring to but everyone jumped on it as if he was suggesting people drink bleach.

Let's not be too unduly dismissive of chemical disinfectants either.

I love the idea of decreasing toxic chemical use. At work I use plain old 70% rubbing alcohol or hydrogen peroxide for wiping down surfaces--they both seem fairly benign. My daughter worked at restaurant where they use UV light to sterilize the menus, tables, chairs and more. She actually quit the job because of the staff's carelessness with the UV wand. She said many servers would wave it around in hers and people's faces, seemingly w/o any concern for UV light safety (skin cancer, blindness) in mind.

Why didn't osha mention uv in air filters for covid is puzzling? uv in air filters is safe as is internal to the machine. Wonder why vaccine mandate is the only to go

There was discussion early on of performing a dialysis-like procedure that would expose the blood to UV light thus destroying the virus.

My daughter’s dance studio has been using these since spring 2020. The owner thought it was the most cost effective way to deal with COVID and kids.

Noblesse oblige indeed. The Gates Foundation is currently sine qua non of noblesse oblige...

Hair dressers used to put their instruments in a UV like box all the time when I was a kid.

The excimer lamps featured in the article which are eye-safe yet effective are in their (manufacturing) infancy and extremely expensive, hundreds of dollars per, even for low wattage lamps. They *could* be made low cost in the course of time. The lowest I've priced them is in the neighborhood of $400 for a single 10 watt lamp and driver.

Short wavelength LED's are also new and very expensive. However, there are a few Japanese studies showing the far cheaper and readily available (and eye safe) 365nm UVA LED's, a wavelength not normally associated with germicidal activity, actually appear to have a strong germicidal effect. https://link.springer.com/article/10.1007/s11517-007-0263-1

Thank you so much!

We nebulise what inorganic antiseptic we have, all have “safety papers”, one can use as additional “choice” besides UV.

Use for rooms, or inhaled.

Preventive or therapeutic.

Even without some machine doing prevention in room air for ClO2(aq) 0.3% called CDS, chlorine dioxide solution: 10ml/10m² room area.

(Source: COMUSAV’s physicians.)

(Not smellable <0.1ppm, ideal 0.01..0.1ppm.

(Danger: Inhalable only up to 5ppm.

No even slight coughing urge tolerable!

Irritating = self warning.

Damage for >10ppm at alveoli is possible.

So safety margin 10ppm/0.1ppm is nice 100x. And self warning. Show me another….)

Here is the publication that found ClO2 reduces the “absenteism in school children” by factor (!) 2.6 if applied by 0.03ppm in classrooms of one group of schoolchildren vs others without the air “deodorant”.

They used a machine to have reproduceable concentration .03pm, but this is not necessary, imho.

From FFP2 N95 mask “mandates” we know: aerosols are not the culprit. Otherwise they would produce a step down 10days after issued in first derivative of incidence in respect to time, which they did not. Let’s overlay all mask mandate introduction points of time for arbitrary precision.

It’s all the fault of fine droplets suspended in air as some fluid, ballistically shooting 3m on nose blow, cough or sneeze, perhaps some snoring, then sinking down in 40secs.

Fluid: they get perfectly reflected from an “elbow”; or mask as it lifts from skin while sneezing of course. And still shoot 3m unpredictably deflected from elbow or the slit between mask and skin they het out sideways-behind.

So let us use inorganic antiseptics as virtual mask where infections start, 1/5 in saliva glands, 4/5 in throat ring, and only some 1% in upper lungs or nose.

So gargling alone is reaching 99% of primary infection sites.

Inhaling nebulised inorganic antiseptics of course is most effective both for prevention as well as therapeutic. Papers are there for many orthogonally working remedies.

I bought a UV disinfection lamp for this purpose in April 2020. I remember being surprised at the time that it wasn't harder to get one, since it's such an obvious solution to a problem. This was back when toilet paper was still sparse on shelves around here.

As a child when we went to a barber, not a hairdresser, they used to have a UV steriliser cabinet on the shelf to sterilise the tools of the trade , scissors, razors and combs.

Do we have a heads up on this?

“If DNA damage cannot be properly repaired, it will contribute to the amplification of viral infection-induced pathology. Therefore, we aimed to investigate whether SARS–CoV–2 proteins hijack the DNA damage repair system, thereby affecting adaptive immunity in vitro.”

“Together, these data show that the SARS–CoV–2 full–length spike protein inhibits DNA damage repair by hindering DNA repair protein recruitment.”

“This suggests that the use of antigenic epitopes of the spike as a SARS–CoV–2 vaccine might be safer and more efficacious than the full–length spike. Taken together, we identified one of the potentially important mechanisms of SARS–CoV–2 suppression of the host adaptive immune machinery. Furthermore, our findings also imply a potential side effect of the full–length spike–based vaccine. This work will improve the understanding of COVID–19 pathogenesis and provide new strategies for designing more efficient and safer vaccines.”

Stew Peters interviewed an anesthesiologist about this technology a few weeks ago, and mentioned a company that has already been installing 222nm products (faruv.com). Has anyone heard of any such installations? I’m thinking of having them installed at my daughter’s school.

When I started first grade in 1952, my school had UV lights in every classroom. Of course, we had measles, polio, chicken pox, etc. to contend with.
