First, what is the difference between a Mask and a Respirator?
Why are the legitimate experts on COVID-19 and respiratory illnesses in general say that you must upgrade to a respirator?
What to look for?
I started with cloth masks in the first Wave, around March/April.
Here are the two types I used. I have not provided links to the vendors because I want you to have better, but there are good things to learn about Fit.
Filters I used with my cloth masks.
It is a good learning experience to share, because the lessons about Fit and Filtration carry forward into Respirators.
If you can't afford respirators, government should be supplying you. The cost-benefit for taxpayers is worth it.
Wrapping up the lessons on cloth masks & their filters.
Salespeople use this, but please look at the VALUE of a respirator, rather than PRICE. I don't drive by Starbucks to drop $5 on coffee every day, that I can just switch to respirators.
Reminder that I am speaking as a citizen in a democracy, from bona fide belief, with evidence I believe to support my opinion.
Getting deeper into the Vanch masks.
I did a thread about this in April 2020, and shared this information with several healthcare leaders, unions at various levels, and managers at several facilities.
In my view AHS and Alberta Health responded to the concerns raised by unions and medical associations with deceptive information about this "PPE" to the joint Health & Safety Committee.
I raised this again in Nov 2020, and appreciate the courage of physicians to speak up too.
Disappointed there was no take-up by the NDP despite several efforts. I am not a member of any political party.
Independent journalist @kim_siever did an excellent investigation into the Vanch masks in May 2020, showing:
• quality issues
• Vanch was not the manufacturer, but was laundering spot-market mani-pedi masks
• cronyism and over pricing
Digging deeper into Vanch's Failed Splash Resistance, aka Worker Protection from Bodily Fluids emitted by their Patient.
The Vanch masks failed this, and IMO AHS used more deceptive language to cover this up.
IMO, AHS knows their Vanch masks fail to provide the Splash Resistance their workers expect, but uses deceptive PPE disclosure to risk their lives on that too.
It's like saying condoms with pinholes meet some bogus standard for condoms with or without pinholes.
Summarizing the Vanch mask issues, primarily for engineers & OH&S specialists.
Happy to be politely corrected on this, w good sources, if I am mistaken.
Any discrepancy between what these experts say and what I say, I defer to them.
I'm a generalist, taking you on my own journey from cloth masks, through Blue Leakies™️, a frustrated dive into Vanch masks, and now into respirators.
Like the new bare minimum, KN95 respirator.
I'm also showing you the classical 3M N95 respirator, with the classic cup or dome design.
3M has other options which are more comfortable, and/or fit better, therefore making them more functional.
Pulling you further from masks to respirators, there are many companies outside and inside Canada (hi @CAPPEM2) that make N95 or N95-equivalent, or the emerging CSA standard.
But I was most interested in a NanoMask, from @BarryHunt008's Prescientx
• partly because I have come to know & respect him
• partly because NanoMask is excellent, w full disclosure of test results
So because of development in the 🇨🇦 CSA Respirator Standard and labs to certify products to it (see tweet above with the 3 twitter conversations about that)..
I get why NanoMask is ASTM Level 3 ++
Totally comfortable with its Fit + Filter + Function compared to KN95 or N95.
Now, if you've been doing the math with disposable Blue Leakies which you are getting for $0.50 or so (AHS pays $1.50 each for 40m over 2 years!) you think a $20 mask/respirator is a bad deal.
But the NanoMask lasts a lot longer. Especially if you have 2, and you rotate them.
I got my NanoMask Fri 10 Dec.
• First Sunday I wore it for 5 sweaty hours in library as I made 6 binders for work
• Have worn it 2 - 4 hours/day for groceries, LTC visits, etc until Tue 21 Dec
• Trying different model now
Still like new. I agree with @BarryHunt008's letter.
@BarryHunt008 Now, I have had my eye on the Prescientx Breathe mask (which I can call a respirator) that they're clearing out for a Heckuva deal.
$50 including 500 filters because inventory is being cleared out.
@BarryHunt008 The Breathe Respirator has many wonderful traits:
• High Filtration and Low Breathing Resistance of NanoMask filters
• Wonderful fit of an industrial silicone respirator housing soft as a diving mask
• The harness to attach it to your head....not so good
@BarryHunt008 Not slamming the harness, because as I explained earlier, when governments and ID Docs:
• denied #COVIDisAirborne
• forced HCW to wear Blue Leakies™️
• told the public just distance 6 ft
• then finally cloth masks
• they killed business case for further product development
I just wanted to show the harness problem well enough to show:
• the solution was hanging right around my neck
• from my favourite cloth mask
• instead of trying to go ear loop + lanyard
• just go simple head tie
• with a FLAT work boot lace
So I'm sorry if I push demand past your remaining stock of filters, @BarryHunt008, or housings your supplier has left.
I just love the Breathe. It was worth me learning & fighting through 2:20 limit on Twitter videos, to show how to fix the harness, for existing & new owners.
This was my labour of love tonight.
Full use of my skills, and my sleep.
#Omicron will need us to learn, and apply to the very best, every tool in the shed to prevent our province/country/planet from being overrun by the nastiest mutation of #COVID19 yet.
Be safe, everyone.
Here are the 3 slides I was working with tonight to summarize the Vanch mask issues
In Alberta, babies under 1 year old are getting clobbered by Respiratory Syncytial Virus (RSV), and it is overloading our children's hospitals:
• Hospitalized at 36x the rate of average Albertan
• Hospital & ICU at 3x rate of COVID in babies under 1
Typical LaGrange-style quote in reporting by @JenLeeCBC:
"In a statement emailed to CBC News, a spokesperson said the hospital is seeing an increase in respiratory admissions, which "aligns with seasonal trends.""
Expecting mothers should speak with their family physician or obstretician (like @FionaMattatall) about getting vaccinated during their pregnancy to protect their newborns. (I'm not a doc)
RSV shots are $1000 each, but perhaps other immunizations.
Both last year and this year, peak weekly flu shots administered was in week 42:
• This yr, only 243,207
• Last yr, 330,264
Many of us are now off from school or work for the Xmas holidays. Good time to get vaccinated. It should help you for January return to school or work.
3-min video posted 31 Oct 2024 by Liricom & Plenary shows what they expect provincial taxpayers to build + operate for them between airport & "Grand Central Station".
Before I get into pros and cons, let me just help you figure out their bizarre colours:
🟧 for Calgary Airport Downtown Express track that is at grade or in the 80th Ave tunnel
🟦 Teal (close enough) for stations
🟨 for track that is elevated from Bow River near zoo to Crowchild
Why does it need to be elevated from south shore of Bow River near Zoo, to Downtown West End before Crowchild?
Because CPKC wouldn't let them stay parallel at grade though downtown. Needed to be elevated to not interfere with freight loading/unloading at grade.
When UCP claims their elevated track & station #GreenlineYYC design through Beltline into Downtown is better than tunnels, but🚩won't release a single rendering, others will.
😱
Visit @yycbeltline web page, where each image is labelled. You barely recognize the streets after.
@yycbeltline Beltline Neighbourhoods Association tries to recreate Dreeshen's claim that only one "non-driving lane" on 10 Av would be affected (after multi-year construction probably closes the whole street) by rendering only a single column for the track and two columns for station.
@yycbeltline They use structural designs from Sunalta, which is 15 m above ground, but have to render two columns straddling reduced 10 Ave to support Beltline station.
Sunalta station is supported by an enclosed building, with interior stairs, escalators & elevator.
Confirmation GoA's plan for Green Line into downtown is terrible:
• no press conf
• nowhere in press release do they state where it crosses the rail tracks, or meets 7 Ave
• only 1 high level map - no renderings or closeup on downtown
• no AECOM quote
@TheBreakdownAB @GregGinYYC @DuaneBratt @CWalcottYYC @jasmine_mian @JyotiGondek @cspotweet @AdamMacVicar @LiveWireCalgary @GreenLineYYC Rick Bell's "exclusive" claims the crossing into downtown is at 2nd Street SW, but I refuse to link to that propaganda. @LiveWireCalgary has always provided excellent, deep journalism on #GreenLine and they confirms the crossing AND the cheap blindside.
@TheBreakdownAB @GregGinYYC @DuaneBratt @CWalcottYYC @jasmine_mian @JyotiGondek @cspotweet @AdamMacVicar @LiveWireCalgary @GreenLineYYC Some quick work with Apple Maps 3D views shows crossing into downtown at 2 St SW requires:
• elevation over a circular ramp and vehicle bridge across the tracks to parkade
• crossing two Plus 15 pedways
• a third Plus 15 medway just north of 7 Ave
My concern about privacy, like everyone's email address shared with everyone else in the group, have been resolved with the oddly-named "See all event details" access permission, which doesn't even show the guest list.
But there are still other privacy concerns I want to check.
Obviously, the owner of the shared calendar would have to know the email addresses of the PFC members who want to subscribe to it.
I don't know if any one of the subscribers can see who the other subscribers are, or their email addresses.
