Default Be very careful using UV lights.

If you don't know what you are doing. Sterilisation crews are trained and wear protective gear using UVC.
Or like in a hospital sometimes robots are used. C can be deadly, your old blacklight is UVA but with extended
exposure it can cause eye damage.

Since the control board need fixing, I fixed it but it is not as easy to use, I have not used my sigs. tanning beds at work, my white butt skin shows it.
I may have to stroll on down and use them.

This new UVC is showing promise, it doesn't harm human cells but burns the crap out this bug. Its about time we take
this fight to the enemy. Tierd of seeing us hiding and living in fear. Burn em, burn em all.

Read this from the BBC.


“You would literally be frying people,” says Dan Arnold, laughing in disbelief.
Arnold works for UV Light Technology, a company that provides disinfecting equipment to hospitals, pharmaceutical companies and food manufacturers across the UK. Recently, as the global anxiety about Covid-19 has reached extraordinary new heights, he’s found himself fielding some unusual requests.
“We had an enquiry from a private individual about our equipment, saying ‘Well, why can't we just get one of your UV lights and put it up on the exit to the supermarket – people can stand under it for a few seconds before they go in’,” he says.
Among the abundant “health” advice currently swarming around the internet, the idea that you can disinfect your skin, clothing or other objects with UV light has proved extremely popular. In Thailand, a college has reportedly even built a UV tunnel that students can walk through to disinfect themselves.

So is this a good way to protect yourself from Covid-19? And is it true that since “the new coronavirus hates the sun”, sunshine will immediately kill it, as some reports on social media have claimed?
In short: no. Here’s why.
Dangerous rays
Sunlight contains three types of UV. First there is UVA, which makes up the vast majority of the ultraviolet radiation reaching the Earth’s surface. It’s capable of penetrating deep into the skin and is thought to be responsible for up to 80% of skin ageing, from wrinkles to age spots.
Next there’s UVB, which can damage the DNA in our skin, leading to sunburn and eventually skin cancer (recently scientists have discovered that UVA can also do this). Both are reasonably well known, and can be blocked out by most good sun creams.

There is also a third type: UVC. This relatively obscure part of the spectrum consists of a shorter, more energetic wavelength of light. It is particularly good at destroying genetic material – whether in humans or viral particles. Luckily, most of us are unlikely to have ever encountered any. That’s because it’s filtered out by ozone in the atmosphere long before it reaches our fragile skin.
Or that was the case, at least, until scientists discovered that they could harness UVC to kill microorganisms. Since the finding in 1878, artificially produced UVC has become a staple method of sterilisation – one used in hospitals, airplanes, offices, and factories every day. Crucially, it’s also fundamental to the process of sanitising drinking water; some parasites are resistant to chemical disinfectants such as chlorine, so it provides a failsafe.
Though there hasn’t been any research looking at how UVC affects Covid-19 specifically, studies have shown that it can be used against other coronaviruses, such as Sars. The radiation warps the structure of their genetic material and prevents the viral particles from making more copies of themselves.
As a result, a concentrated form of UVC is now on the front line in the fight against Covid-19. In China, whole buses are being lit up by the ghostly blue light each night, while squat, UVC-emitting robots have been cleaning floors in hospitals. Banks have even been using the light to disinfect their money.

At the same time, UV equipment suppliers have reported record sales, with many urgently stepping up production to fill their orders. Arnold says UV Light Technology has run out of all of its equipment already.
But there’s a major caveat.


UVC is really nasty stuff – you shouldn't be exposed to it – Dan Arnold


“UVC is really nasty stuff – you shouldn't be exposed to it,” says Arnold. “It can take hours to get sunburn from UVB, but with UVC it takes seconds. If your eyes are exposed… you know that gritty feeling you get if you look at the sun? It’s like that times 10, just after a few seconds.”
To use UVC safely, you need specialist equipment and training. The World Health Organization (WHO) has issued a stern warning against people using UV light to sterilise their hands or any other part of their skin.

We have been using uv disinfection at a waste water plant for over 10 years. It does NOT destroy an organism, it makes it unable to multiply. We sample before and after the process on a regular basis to prove to the its effectiveness. Regular polycarbonate safety glasses have a UV shield coating on them. The problem I see using them widely is cooling them and their electronic components. It does not take long for them to do their job, our water is in the process zone for 3-5 seconds and then off to the river.

I already posted that as a link a week ago, I'm glad you stole it and made it readable. So you were the first site reporter, Stop stealing my stuff. You give me no credit for anything. Who posted about this first you, no.
That was two weeks ago, I have much more, you could steal.

I don't do that here. Only so I can can look good. Find it yourself. I Ihave much more than that.
You wanna steal it too. Find your own dam articles

Good grief, Argent. I didn't read your previous post, I did read this one and went looking to see what I could find out about UVC, found the link, and posted it. I don't feel that I stole a **** thing from you. Grow up, put on your big boy britches, and get over it. I have no wish to "steal" your thunder and REST ASSURED that I won't bother with anything else you post. Suck it up, buttercup, lose the chip on your shoulder, and you will feel better.

Suck your pants up little man, you don't have the ability to go out and find something even better.
When I have a lot more than that which is very much better. That was only a precursor to my thread post.
Tells me you don't read anything I post, such a good friend you are.

So bring in your trolls I'm sure they are waiting. I didn't post it as read only, because it was malware loaded.that way.
My link wasn't.
