Thread: The C. Virus and human reaction

Saw this recently in the Ottawa Citizen.

This fellow provides a whole new take on educating your kids at home during school closure and social distancing and isolation. It’s a good read.

Randy, I'm happy for you. That goes a long way to explain why you're still single.

If anyone has a 3D printer you might find this interesting:

I would have a hard time using these in a situation that needed more than a surgical mask.

Riding the bus or a subway ok but not in a situation where a heppa is needed. A couple of reasons.

1. both guys in the video have beards. Don't try to sell me a mask having a beard!

2. I like the idea that the masks can be heated in hot water to form fit but then every mask would have to be fit tested.

3. This brings up that even every major manufacturers models should be fit tested. If we change from brand X to Brand Y we have to be refit tested for brand Y even though we passed for brand X. Open source is cool but every printer/manufacturers model would have to be separately fit tested.

4. Where are these common parts such as valves coming from? You could print a million masks but if you didn't have the check valves what good are they?

I would trust these similar or less that the mask my mother could sew out of cotton material with elastic ear straps.

It's my understanding that the process makes the valves.

I think that the idea is to be able to make masks for yourself for things like being on buses, stores etc. However I'm not trying to over think these kinds of things. I don't have a printer and I just maintain distance between myself and other folk.

About beards---when I was in the Navy, beards were allowed, but when I was in Submarine School, the petty officer who was teaching about the OBA (Oxygen Breathing Apparatus) had a full beard and he pointed out that if he was ordered back to sea that the beard would be the first to go as it wouldn't allow a good fit of the OBA.

Just common sense in my mind.

Yes, depending on what type of facial hair you are sporting it can interfere with the proper fit of a mask. Masks come in different sizes, at least they did where I worked, and had to be fitted to your face. Beards were a no no onboard a ship because you could not get a good seal when using the MSA Chemox breathing Apparatus. It used chemicals to produce oxygen to breath.

The OBA of the past looked very similar to your MSA:
