Didn't wear mask
Comments (8)Well, let's try again. I wrote a long answer, hit Preview Message, and it completely disappeared!!! Anyway, I hope you'll be OK, since I did worse than you. Started leaf casting last summer, it had no warnings on the bag, so I figured it was safe, until I researched it further (about 2 months later!). Oops. I was outside and tried not to breathe it in, still I'm sure I inhaled some. Although I'm far from being a doctor, I believe you normally would have to do that for quite some time before it's too dangerous. I'm thinking that because my husband used to work in a dental supply place, some people there developed Silicosis, but they were the ones who worked with the powders for many years and didn't wear the masks they were supposed to. So I'm hoping we both know better now and dodged a bullet! :)...See MoreMore experts say Americans should probably start wearing masks.
Comments (121)" Making your own face mask? Some fabrics work better than others, study finds " This study, non peer reviewed and non published that's touted all over NBC is, sorry, looking at the issue in the wrong way. They studied how various materials can filter out the virus, which is tiny teeny, 03 micron. Sounds like this means that they're trying to prevent incoming viruses from infecting the person who wears the mask. However, one primary mode of transmission is through face-to-face interaction. Fact is that in normal interaction, speaking, coughing, sneezing, the virus is ensconced in droplets --- these droplets are way, way bigger than what Segal tested. Therefore, 1. The point is to look at how to prevent EMITTING these virus carrying droplets, that is, the wearer prevents transmitting his/her infection to others. And this is where face covers are extremely efficient: They block the spit droplets from leaving the mouth of an infected person. 2. So, any meaningful tests of protective mouth covers needs to test such droplets. 3. Yes, there is evidence that such droplets that are emitted by talking, sneezing, coughing can become aerosolized, ie become tiny, the size of what Segal tested. However, again, this can be prevented by emitting droplets in the first place. Super frustrating to see some anesthesiologist's unpublished, non-peer reviewed "study" be all over the Internet....See MoreCleaning Lady Refuses to Wear Mask
Comments (86)It isn't practical to test everyone, all the time to determine who is or is not a carrier on any given day. It's not even practical to test everyone who feels like they had covid 19 and are recovered. It's not cost effective. Just like it is not cost effective to drug test 100K welfare users at a cost of 1M to catch the 1000 who might test positive on any given day, thereby saving 300K. Do the math. To be economical, one parses sparse resources to where you will get the most bang for your buck. Not sure that all these people who feel like they should be an exception to the rule are liberal or conservative. In fact, they are just folks who get off breaking rules in some cases. Don't get me started on folks I know who work in retail and have to argue with people saying their dog is a "support animal" so that they have to bring them into a store. Or any number of safety rules that I have had to enforce that someone argues for because their case is special. No dogs allowed in the park but my dog is special, no collecting of plant material but I just took one small flower, etc. If the rules don't apply to everyone, that isn't fair. And if everyone gets to break the rules, then they serve no purpose. Rules help people survive living together in groups. Stores have safety rules. "Don't climb on the shelves" for example. Does that impede your civil rights? Perfectly reasonable for businesses to employ safety rules to keep their customers and employees safe. Also perfectly reasonable for an employer than to ask that their workers comply with safety rules. I had to handle lots of hazardous materials in science lab and in landscaping. I got in trouble if I didn't follow company safety regulations. I never felt my civil right were being trampled on. See someone get thwapped in the eye once by a branch ricocheting off a tree being cut down, and you'll never again whine about having to wear safety goggles when using a chainsaw, even if said goggles are hot as blazes....See MoreKN95 mask?

Comments (17)Here's how the hospital my son works at fits N95's. After putting on the mask, user enters a positive air unit. An odor is introduced into the unit and the user adjusts the mask so the odor cannot be detected through the mask by the user. If the mask is adjusted or removed by user once out of the positive air unit, the procedure is repeated. According to my son this mask is near but not quite 100% effective when this procedure is followed. It is also hot, uncomfortable, and restricts air intake for user somewhat. And snowflakes complain that the common cloth and paper masks that most everyone uses are uncomfortable. They have no idea what uncomfortable is. BTW, my son's hospital had a ward devoted to COVID in the spring. It was reduced to half ward this summer, and the remaining half designated for COVID was half full, so a quarter ward. As of last week the ward was half full of COVID patients so the whole ward will probably designated COVID shortly. He also has a co-worker with COVID who has been intubated for 2 months and is not expected to recover....See More- 4 years ago
