Default Interesting Times

So, I'm researching some ideas regarding the current plague being pushed in another blame Trump scenario. I couldn't give a damn about that. But, I'm in personal self preservation mode. What I am trying to come up with is a positive pressure breathing apparatus.Utilizing UV-C sterilizing lamps. Working exposure seems to be around 2 seconds for effective results . I believe due to my employment scenario even if there is a quarantine. I will be going to work because guess who services the hospital compactor. I've been trying to establish baseline requirements as far as blowers and CFM flow rates without trying to re-invent the wheel . Speedglas adflo helmets trigger a warning at 6 CFM . So, based on my Ouiji Board engineering system I would be golden at 12 CFM. Yup, Highly scientific but I believe still in the ballpark.

Sounds like a good idea.
Why the air flow?

When I was pressure washing I had to have just a little air flow to keep from fogging up the inside.

In the 11 to 23 range you are into PPAP machines . No Uv though .

Like I said this is is seat of the pants engineering. I need enough airflow to maintain positive pressure negating any need to be clean shaven for a seal. But, slow enough airflow to allow incoming air to be sterilized by the UV lamps. Which based on my research so far need at least 2 seconds to treat incoming air. I would prefer 5 seconds as a safety cushion. I'm thinking of running the incoming air through a labyrinth style intake chamber with constant UV exposure after coming through HEPA intake filters.

I been also thinking, that is if things get bad.
UV lamps I think is a good idea.

no one wants to say how long the virus lives on surfaces I'm hearing from 2 hours to 9 days, at that you may need a UV room.


1, 2) pictures
I used this when pressure washing, had to go with full face because safety glasses were useless.

3) picture off the net looks like the way to go, add a positive air flow.

Looks like the KISS principal to me Go raid the local water company for bottles and your good to go. I actually found double bib hoods for around $200. The inner hood bib ties under your arms and allows cooling air to pump in. while the outer maintains a system seal.We still aren't talking bio-warfare garb. But, I think sufficient. Tyvek coveralls supplied air hood and basic pre-op style cleanup procedures. Should give you a chance at staying healthy.

I think it boils down to taking as little risk as possible. We have 2 cases here. Next province over is a port city. They have 27 cases and counting. They welcome immigrants. Most their cases are from Iran 50%, 2% from cruise ships, and the rest from China.

I realized that virtue signalling about how righteous and anti racist you are has a price, when I saw my grandchildren sick all the time. Of course the parents are socialists busy infecting schoolkids with their ideology, so they were incensed. Now they have moved out to Vancouver Island and the kids are healthy and happy. Parents are puzzled, but Marx must have an explanation.
We let people in from countries where they have been in contact with diseases we never heard of, and have no defense against in our immune system. Who cares, medicare is "free"

Not the case in this pandemic, but the same rules we should live by apply.
Stay away from rapid transit, big cities and airports, any area where carriers congregate. In my case, having a full bottle of oxygen on my torch cart is my backup because it kills over 50% of my age group, and pneumonia will do me in. We have enough food and meds to cover us for 4 months. All our bills are paid online, as running around paying bills in offices is another vector for disease transmission.

We are not stockpiling anything, this is our normal winter situation.

Same thing here.

Pretty much the same for us. We try not to HAVE to go to the big city very often.

I THINK that the difference between welding oxy and medical oxy is the price. Are there any other differences?

I used to have some First Aid room stock and one of the things was a Oxy bottle spud to a medical post adapter. When I took industrial First Aid they taught that in an emergency when a person needed oxygen and an med oxygen tank was not present, you could roll the welding cart over and punch a hole in the patients hard hat and put the torch tip through it and set it over the patients face for an improvised mask.

Bottom line is that many a hung over welder has sucked on a torch to feel better and ease his headache and the oxygen did him no harm.

As for risk, I have cancelled my appointment with the shoulder doc, and will do some exercise at home to increase shoulder movement....which is pretty damn good as it is. As I write there are a thousand Chinese heading to the Vancouver and Toronto airports on two flights. When government shows how weak and incompetent it is, we have to look after ourselves.
