In the original spirit of Paul's thread, I thought some of you might enjoy this one...
So one of the guys in our Maintenance Dept. the Electrician Superintendent (very recently appointed to that position) actually came up with this homemade device to disinfect an entire room using Ultraviolet light. It's a pretty simple thing... four tubes, some circuitry, and a timer. Some documented experimentation determined 25 minutes of exposure to the UV rays killed or inactivated viruses and bacterial media. So they got to work and built a couple of these contraptions to be used in the event of an outbreak our offices and facilities needed to be sterilized quickly. You just plug it in, put the protective glasses on, set the timer, and leave the room until it's done. So far, we've been spared the worst of this pandemic here in Southwest Virginia. We hope never to need these things, but iffn' we do, they're ready to go.
