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
But the City doesn't tell you the $17m/yr is a mortgage payment, of which only the interest portion is operating revenue.
The City lies to you these are all Lease Payments.
On this mortgage, at best the City is getting a breakeven. The City is showing no Interest Income on it.
Let's pretend this is a lease:
• payments starting at $17m/yr
• rising at ridiculously low 1%/yr
• as if CSEC is an affordable housing client needing a rent cap.
CSEC gets ALL the revenues of $1.2b of taxpayer dollars, custom-built, for only $17m/yr.
🧵 Stampede Park Arena aka "future Culture & Entertainment District Event Centre"
City of Calgary's presentation of the financials is deceptive:
• overstating direct benefits to City
• overstating CSEC investment
• understating City investment
• especially from Reserves
Citizens of Calgary do not get a referendum on the deal. In fact, "public consultation" was limited to an announcement on 25 April 2023, releasing this deceptive report.
Our "Referendum" is the Provincial Election Monday 29 May, and its advance voting.
How is City's report deceptive?
• Pretends $316m worth of CSEC mortgage repayment over 35 yrs is upfront capital investment
• Hides the fact the City needs another $316m up front to build arena complex - from Where?
• Disguises $17m/yr of mortgage payments as Lease Income
@JorgeDe83010797 Hi. The other night we chatted briefly about locomotive axle bearings on @MriyaReport and I decided to get up to speed on it a bit. If you want to chat about this on the Spaces, let me know. I can cover generally while you dive deeper.
@JorgeDe83010797@MriyaReport This video goes deeper into the assemblies. I gathered from the Spaces that Russia does not make the bearings themselves, but was curious about their domestic capability for fabrication and maintenance of all parts of the axle box, or even the bogeys.
Let me know if I misunderstand.
• 2 wheels + axle + gear = WAG = wheel set
• 2 or 3 wheel sets assembled into bogey aka truck(?)
• axle box contains the (tapered) roller bearing and transfers load to axle
• have to track roller bearing wear & replace
🧵 Gov of Alberta's Backdoor Prohibition
on School Mask Mandates
IMO, this is the policy holding back EPSB and other school boards in mandating masks in any school, for any period of time, no matter how bad the outbreak.
How is a 6 Sep 2022 Policy a collateral attack on a 26 Oct 2022 Decision?
Because Justice Dunlop made it clear in August that Minister Lagrange would have to enact a Regulation to prohibit masks, not just write a letter and threaten school boards.
