Thread: CoronaVirus ==> Empty Shelves

We did LOTS of testing in our clean rooms regarding the transfer of dust particulates from operators to various parts of the lab.
Counteracting that was that we had to control exposure to nasty acid vapours in other parts of the labs.

Instead of cross flow we used positive pressure down flow chambers to create air curtains to separate people from samples and negative pressure down flow chambers to separate acid vapours from people. We also used transparent plastic curtains and clear polycarbonate sheet to separate some spaces. It got very complicated really quickly.

We only needed about 100 fpm to protect samples from the small amounts of dust generated by a full PPEd operator but for the acid vapour air curtains we used up to 800 fpm. I'm pretty sure they don't worry too much about air flow in hospitals.

I believe plane air goes down over passengers into slots in the floor before it's refiltered..

Maybe that's what wait staff need to wear. Even better, they could operate a pair of those arms you see in Nuclear labs.

Sounds like Trump might be gearing up to fire Fauci. Some failed politician in CA tweeted something about time to fire Fauci, and Trump retweeted it. Fauci will be answering questions on C-Span at 10am AEST tomorrow.....if he hasn't been sacked by then.

Can't have people contradicting the despots/tyrants edicts.

They are doomed.

Aspects of your suggestions are not as silly as it sounds.

Just as wood working fine dust can be controlled by the use of ventilation the same could be applied to restaurants and I reckon I could set up a restaurant whereby the transmission of any breath base bug could be very significantly reduced.

1) diners wash/sanitize their hands when entering

2) Social spaced seating goes without saying - diners 1.5m apart. Maybe even only 1m apart depending on the efficiency of 2)

3) Vertical airflow curtains - a bank of HEPA Filters covering the whole ceiling dumping clean air down over diners to vents in the floor and recycling it back to the HEPA filters.

4) Chefs, kitchen hands and wait staff in PPE - apron mask, gloves and face shield.

5) Air flow curtains between chefs and food being prepared

6) Food covered immediately after cooking and uncovered only at the table in front of diner.

I'm surprised no one has set such a thing up - could be a good marketing opportunity.
The PPE could be theme styled eg punk, goth, renaissance, space age, grunge, wild west, etc could even be fun!

BobL, a dining experience like that sounds a little unromantic

Not exactly the most romantic night down the local French restaurant tho.

But I certainly get were your heading Bob.

Cheers Matt.

Dunno, my understanding is that latex, leather, masks and whips are highly desirable by some people?

BTW SWMBO is thinking of doing a mask with 3D embroidered/crocheted corona virus models handing off the front of the mask?

Geez, missed that obvious one (for some people!)

Today's spreadsheet attached.

Points to note

• I do not trust the figures from China, Iran, Russia, or Brazil. Maybe not Japan either.
• The Stans are now starting to appear in the 1000-2000 cases list
• Algeria doesn't quite have 2000+ cases but their death rate is top of the chart at 15.8%
• Spain, Italy and France are all slowing on both counts, but still have awful double digit death rates, as do UK, Belgium, Netherlands
• Germany's death rate is <¼ of the other big Euro nations
• Australia continues to slide down the cases list (-5 to 31) and is at or near the bottom in the other metrics
• Europe has 46% of world cases but 66% of the deaths. Euro nations with 2000+ cases are 7% of world pop.
• USA has 36% of world cases and 20% of the deaths. USA is 4% of world pop.
• The entire rest of the world (89% of world pop) has 19% of world cases and 14% of the deaths.
• If you don't have C19 then the safest place to be is probably right here (or NZ). IPM is relatively low at 250/mill, and if you do get it the death rate is one of the very lowest. All other countries with a lower IPM than Australia have a higher death rate, except Russia (and that will change).

been dreaming up money making ideas....
1 cheap pens engraved with Ruby Princess
2 coffee mugs...the same as above.
3. ditto teaspoons
I think I am on a winner, esp at next year's cruise ship markets

I think you might find Carnival management will be re-naming that vessel at the first opportunity.
