OT: Covid-19 personal protection ideas, and related

the first time mankind has been confronted with a dangerous disease with a long (and silent) incubation period, a relatively high infection rate *toge ther* with a great deal more understanding of how infections work. Every re sponse created prior to COVID19 is instantaneously obsolete

you actually think no-one planned for a pandemic for which we have no medic al cure? C'mon.

Silly easy tip that emerged from Scottish Gov TV piece today. Have a bottle of sanitizer , or as that is Scotch Mist around here, a small bottle of methylated/denatured spirit , hidden but easy access near the front door but on the outside of yur house. Everyone who enters uses some on their hands before touching the door and entering.

Coronavirus: Tech firm Bloom Energy fixes broken US ventilators By David Molloy Technology reporter

30 March 2020

A Californian company that usually makes green-energy fuel cells is due to deliver 170 repaired ventilators to Los Angeles later on Monday after transforming its manufacturing process.

An engineer at Bloom Energy downloaded the service manual and taught himself how to dismantle and rebuild them in a day, the Los Angeles Times reported. ...

Elsewhere in California, personal injury lawyers are boning up on the technical aspects of ventilators in case one or more of the repaired life saving ventilators should fail.

In the U.S., good deeds rarely go unpunished.

Bloom has been asked to repair about 200 Ventilators that have been sitting in a warehouse in my state. So, obsolete ventilators sitting somewhere is possible.

We heard that there are disinfecting gizmos being made.

I wonder if these ideas would work:

1. Germicidal lamp. e.g. from an HVAC system.
2. Hydrogen peroxide, say 17%. Delivery methods: nebulizer, hand spray

Both are hazardous. I built a UV-C light source >500 W probably for work. neat design. The lamp was about 8" x 8" made from a snaked 1 cm tube. power source was a very large neon lamp transformer. Eye and skin damage possible.

I use 17% Hydrogen peroxide at home to clean up blood stains. It works a lot better than 3%. Your skin will turn white. baking soda is use for accidental skin contact.

Can the longer wavelength UV lamp be used for detection? Somebody gave be a UV lamp that could be used for body fluid detection such as urine.

re-using any disposable mask has to really be a problem.

I was watching a Korean doctor talking about mask usage and he said you should wear one. He also said that if the virus gets trapped on the outside of the mask, breathing raises the temperature and humidity and may kill the virus.

The message of not wearing the masks is to make more available for health care workers and discourage hording.

I've used the 3M 8511 at home, so I have an almost full box. I also have a half-face cartridge respirator.

20% water, 80% alcohol is just as effective as 100% alcohol, but doesn't evaporate as fast.

Or use some glycerol.

Or use some Aloe Vera, if you can find some growing (we have lots). Peel the fleshy leaves and the inside is transparent goop you can mash. It's a good moisturiser, too.

Most methods for making anti-viral masks DO NOT WORK. There are some good studies showing what does work, and how well. This is one example:

Dunno, but Medtronic has opened the design documents for its certified products:
