Old Technology could breath new life into Restaurants and other close contact businesses...

In a Duh moment several of my colleagues and I may have just come up with a plan to allow close contact businesses to function safely.

Hospitals use what is called a negative pressure room for patients who have infectious diseases. These operate on specific air flow patterns, controlled humidity, and UV lights which the air is pulled through to kill any virus.

Several Companies manufacture UV lights to be used above head high with slow updraft fans to kill the viruses in the air. They run about $175.00 and two can cover a room that is 100' X 30'. A series of these lights and fans in any restaurant could effectively capture and kill viruses that are airborne. These lights can also be fitted with covers that open automatically to the floor and seating areas every hour to kill surface viruses if the narrow band UV bulb is used.

Narrow band UV bulbs are safe for human exposure if it is monitored and intermittent.

We can add to this structured air flows so that air is drawn downward at walls and floor level around the room. This would pull the viruses downward to the floor where the air handler can push them out above the lights after filtration. You could also incorporate a High Output Light chamber (these are kind of pricey) to disinfect the air rapidly as it passes through the chamber. These were used in TB segregation wards so that the staff was not breathing the same air as the patients.

The technology is out there to bring America back on line quickly. The simple light and circulation fans can be installed in a day.

 
 
Had these ships used UV chambers in its ventilation system many of the infections never would have happened. Ships are notoriously bad for recycling air without venting it.

EUV shorter than 100nm burns skin for a reason. I for one don't want to live in a laboratory all my life. You are talking about a major investment for a business to do all of that. Worse, living in a sterile environment actually LOWERS your resistance and immunity making you more susceptible and dependent within that environment!

And in the worst cases in the country ........High rises.....using POSITIVE AIR in the rooms.....through AC systems that don't have these UV or ionization filter systems...................

Spreading like crazy...........I said this a long time ago when this first started.

You are damned if you do...........damned if you don't...........

If a REAL PANDEMIC COMES.........and these systems don't have them.........well we aren't gonna have enough body bags to stack the dead.

This one is turning out to be only slightly worse than the dang Flu.

Your point is well taken. Where is the happy medium? There is really no perfect answer for this. I guess isolating those who are most susceptible is the primary answer but how do we slow the spread until we gain herd immunity while not killing ourselves or our economy?

To get ourselves some snacks :banana:
Damn, I suddenly have an intense craving to go to a Drive In theater. We have one here on the outskirts of town in Valparaiso, Indiana. I went there quite a few times when our parents took us there in the early to mid 1970's, and I went there once by riding my bike!?! and met my friend there, who biked MUCH farther than I did, to see Jaws in the summer of 1976. They let us in, we sat at a bench by the food stand, with plenty of speakers surrounding us. I haven't been back since, but probably WILL go again as soon as they re-open. Thanks for bringing back fond memories of this. I also went to Drive In theaters quite a few times when I lived in the Phoenix, Arizona area. These trips all occurred in the 1980's except for the last time, around 1997, when I saw the first Scream film.

Yep. And your "happy medium" brings to mind an old and silly joke. What would you call a psychic with a huge grin on their face? A happy medium.

Maybe, maybe not to the point of UVC Lighting to kill Corona: 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.
However, it's not quite as good as we might have hoped. In a recent study – which looked at whether UVC could be used to disinfect PPE – the authors found that, while it is possible to kill the virus this way, in one experiment it needed the highest exposure out of hundreds of viruses that have been looked at so far. The amount of ultraviolet required varied widely, depending on factors such as the shape and type of material the virus was on.
“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.”
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.

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.

So maybe.., maybe not?
