Who was that masked man?

To the dump, to the dump to the dump dump dump… as the loan arranger sang while riding into the sunset with a dustbin on the back of his horse.

On the home front, Mrs S has picked up an unpleasant 48 hour tummy bug. No idea where from. We haven’t been going out much over the last seven weeks except for essential purposes and have been doing the whole physical distancing / wearing gloves and masks. I had the same thing on Wednesday / Thursday and I’m pretty good about washing my hands and personal hygiene. So it must be something we ate. This led me to flush out things like the butter dish, clean the fridge and eliminate any food borne vectors as much as possible. Which is all you can do under the circumstances. She’s on the mend, poor lamb and will be fine by Tuesday.

This post is about masks (again)

Having actually worked in the front line in a hospital, we were used to wearing masks, and I even got a severe wigging on one occasion for picking up a filter, rather than a surgical mask while doing my OT (Operating theatre) placement several decades ago. The guy below reinforces what I was always taught, that the standard surgical mask is just as effective, if not slightly more so, than the much-vaunted N95 respirator.

Of course those selling N95’s will tell you different, but they are wrong because all face masks leak around the edges. The only way to get containment is with a full, air sealed Level A Hazmat suit with an independent air supply and / or filtration. The all over type with big hoods and clear panels. Or an aqualung respirator with positive pressure.

Besides, if you’re working in OT, the standard surgical mask is way more comfortable and doesn’t chafe or leave nasty red marks on your face after only half an hour. All any mask will do because, as I have said before, a masks primary purpose is reduce the radius of infection. Which is why surgeons and operating theatre staff wear surgical masks plus disposable clear face shields. Masks to contain the droplets that we all emit when breathing, and face shields to prevent backspatter from possibly infected patients. Prior to HIV and MRSA, highly infectious patients were rare, so wearing a face shield was not as common as nowadays.

One thought on “Who was that masked man?”

  1. Just a question out of pure curiosity Bill, I can’t find any information on how good a DIY mask would be. The ones I use for the building work on my house are rated FFP3, they don’t leak around the edges because of a large rubber gasket which shapes to the face and they have a filter. I’m interested how FFP ratings compare to N95. I do know the DIY masks are about 15 times the price.
