From what I've read, temperatures of 55 degrees Celsius and above, for at least 20 minutes, will kill covid-19. In fact, isn't that why people get fevers when they contract covid-19? A fever is the body's way of killing a virus by heating up. Usually, it is only a couple of degrees, so to 37 or 38 degrees.
From what I've read in this thread, these workshop environments get extremely hot for people. I dont think you need to worry too much about masks in those areas, for that reason.
Don't be telling bom to beat himself up, Sokarul, I think his decisions are sound.
Aside from masks, washing hands and keeping surfaces clean, is of equal importance. You dont know exactly how or where your employees contracted the virus.
I've had a couple of covid scares this year.
Most of my debating this year, has been against sovereign citizens who are anti maskers and pro protestors.
