Thread: Alberta Health's procedural masks.

@AHS_media: "These masks are all safe, certified and meet ATSM Level 1 filtration requirements."

Longtime supplier PRI•MED follows ASTM F2100-11 (2011).

New supplier Vanch follows YY/T 0969-2013.

@Arfarfarf8 @mchatenay @Dave_Khan
There are key differences between the North American and Chinese standards.

ASTM Level 1 requires both Bacterial (3.0 µm) & Particle (0.1 µm) Filtering Efficiency ≥ 95%.

YY/T is silent on anything smaller than 3.0 µm.

Coronavirus average 0.125 µm.

smartairfilters.com/en/blog/compar…
Depending on the English translation, YY/T 0969-2013 requires the nose piece to be "pliable" or "plastic".

Unfortunately, Vanch took that to mean a non-pliable plastic strip in some batches, and a thin twist tie in others.

We need to see:
- AHS purchasing specification for these masks
- how Vanch was qualified as a supplier
- the test results of the pre-purchase samples
- the QC test results before release to front line
cbc.ca/news/canada/ed…
There are both logistical and health concerns with @AHS_media plan to remove the plastic wrappers from the masks here on arrival. Indefinitely.

Logistical: This is 200-500K masks/day. Who is going to unpack them, and where, to keep the masks clean?

Health: Polypropylene extrusion creates VOCs.

Which VOCs, at what levels, from Vanch's mfg process are trapped in plastic wrappers? What are the acceptable levels? What testing is being done before release to frontline workers?

brady.eu/en-eu/related-…

scielo.br/scielo.php?scr…
Get ready for more issues soon.

"They continue to try and procure other types of acceptable alternative procedural masks, including expecting large orders (in the millions) of new types of procedural masks by the end of April."

In my 3rd tweet of this thread, I mentioned some English translations of YY/T 0969-2013 nose piece say "pliable"; others say "plastic". I accidentally posted same screenshot of "pliable" twice.

I don't have full YY/T & ASTM standards to find other differences. Has AHS done so?
AHS risking life w claim Vanch masks on Chinese YY / T 0969-2013 = PRI•MED ASTM F2100-11 (2011).

Coronavirus 0.125 µm particles aren't stopped by a 3 µm filtration standard.

Chinese YY 0469-2011 is closer, but Vanch doesn't make masks to that standard.

I was going to tweet about my early dinner tonight at Palomino (cliché food pics) but just got hit with wall of SWEET sound when I went downstairs to use the washroom, and opened the steel door to basement concert hall.

WOW.

This is "Olde Ghosts" warming up - in this program. My photo with permission of Olde Ghosts 4-piece band warming up (I'd say they're already on fire) as I went to basement washroom at Palomino (shared with underground concert hall).
In the program they are listed as "Old Ghost" which may just be a miscommunication between Palomino mgmt and Band mgmt. Still gets the message across.
I am a nerdy 58-yr-old engineer who surprises people with 2 unexpected traits: a love for good metal, and endless jokes.

On the latter, I am like Leslie Nielsen who could easily get even people braced for his hidden fart accordion to crack up. But I'm not using one....yet.👺
With metal, I was raised with Indian music my parents played, like the Pakeezah soundtrack, until the cassette literally broke.

This is one of the songs from that movie. It builds until Meena Kumari (Indian's Marilyn) dances with those 2 😍 backups.

Kinda proud of myself. Also.. life is hilarious.

I’ve been eating a lot of rich, flavourful food recently, and I went from a salmon/capers omelet at OEB to the passcode protected washroom in food court at Fifth Avenue Place. Took a massive, relaxed dump.

Laughing as I type.
So I’m washing my hands - even had the foresight to take a restaurant napkin to dry my hands and use on the door lever to exit (trust me on this) and a distinguished gentlemen t about 60 walks in.

And visibly buckles, and groans.

I’m trying not to laugh out loud.
I step out of washroom and all of this is hitting me as I walk slowly to exit escalator, down to a bench on 5 Ave, where I am typing this now.

I’m almost crying not to burst out laughing.

And the Punjabi woman security guard sweetly asks me “Are you OK?”

No, Bhenji. I’m not.

@tylerblack32 @TheBreakdownAB @KmarkovCTV @picardonhealth @JenLeeCBC @MurrayManera @JSJamato @gabefabreau @drDavidKeegan @amandalhu @CalgarysChild @MarciaOnTheGo pbs.org/newshour/show/…Ali Rogin: Dr. Nagata, thank you so much for joining us. Social media children, lots of questions, few answers. What did your study find? Jason Nagata: We followed 12,000 preteens over three years and we actually found big rises in social media use. So during that period, social media on average increased from seven minutes a day to over 70 minutes a day. So a tenfold increase. And in our analysis, we actually found that rises in social media from year to year among these 9 then 10 then 11-year olds were actually associated with future depressive symptoms in the following year. So I thin...
Ali Rogin: So what you're saying is that you found the correlation here to be with social media use leading to more depressive symptoms, not the other way around. You're saying that depression doesn't necessarily indicate use of social media? Jason Nagata: Yes. In our study, were able to follow these same 12,000 kids year to year. So were able to look at both their depression and their social media use every single year. And so we could look at patterns in their use. And we found that those kids who had big spikes in their social media use from year to year then subsequently had bigger sp...
Ali Rogin: And talk to us about the size and the scope of this study. This sounds massive. How did you track this many children and has that been done before? Jason Nagata: So, yeah, the data comes from the Adolescent Brain Cognitive Development Study. It is a national study that follows these 12,000 kids from over 21 different states, study sites across the U.S. and it's funded by the National Institutes of Health and is I think one of the largest studies on child development and social media and brain health ever.
Ali Rogin: That's such a fascinating ancillary piece of information that you found in looking at this data. I do want to ask though, what is your advice for parents with the understanding that this data brings us to. Jason Nagata: Yeah, we actually looked at parent actions for rules and monitoring in the study and we actually found that the biggest predictors of kids screen use was actually their parents screen use. And as a new parent I think it's really important to practice what you preach. So if you're going to tell your kids to put down their phones to important that you role model g...

🧵 Alberta's Reigning Queen of deceptive cherry-picked public health stats, Health Min LaGrange, was back at it Monday, this time over measles immunization.

Bonus Topic: Where is the source for the widespread claim that airborne measles is only infectious up to two (2) hours? Screenshot from Goa 5 May 2025 press release, where Health Min LaGrange made the same claim in the YouTube press conference: [below is the quote verbatim, but I would put sarcastic quotes around "facts"] "Quick facts • Currently, appointments in the central zone are available within one day, while in the south zone appointments are available usually within one to two days. • Following increased efforts to educate Albertans on measles and the importance of immunization, there has been a significant rise in immunizations across the province. Since March 16, there has been a 67...
Excerpt from GoA lengthy web page on measles "How measles spreads Measles is an extremely contagious disease, spread easily through the air. You do not need to be in direct contact with someone who is infected. You can get measles just by passing through a room or location where a person who is infected was up to 2 hours before. The person who is infected does not still need to be there to put you at risk of disease. Measles can also be spread through coughing, sneezing, yelling, singing and breathing."
@TheBreakdownAB @JMeddings @PfParks @LukaszukAB @JenLeeCBC @GosiaGasperoPhD @Mark_Ungrin @dupuisj @DrFiliatrault @TimmCTV Let me provide the links for the above two graphics:

@TheBreakdownAB @JMeddings @PfParks @LukaszukAB @JenLeeCBC @GosiaGasperoPhD @Mark_Ungrin @dupuisj @DrFiliatrault @TimmCTV On the deceptive, cherry-picked measles immunization stats, LaGrange said "Since March 16, there has been a 67% increase in comparison to last year."

Let's look at actual graphs & data tables.

I was just treated TERRIBLY by @HyattCalgary. Manager just denied me service in restaurant for some vague reasons behind:

“None of the staff are comfortable with you and want to serve you.”

Huh? You just lost polite, loyal 20% tip customer. Maybe my friends too.

See you never.
The VP who oversees the restaurant was not on, but I left my business card.

My @Hyatt loyalty card, which shows zero as it has not updated for my purchases since February, when my car died, and I found walking there convenient. High prices, but matching food & service (!) Image
@Hyatt Now, I don’t care about my points, as I will never visit @HyattCalgary again, for any reason.

I won’t spend much time with the VP if he or she calls me. This is their problem to solve, not mine. I’ll get nothing from it either way - I’m gone.

Dear @CalgaryPolice and other smart people. I'm looking for 2 things:
• video of press conference and written response by Chief @neufeld_mark to Dreeshen's stupid announcement early Dec 2024
• GoA policy & evidence to get sites approved for photo radar

calgary.ca/cps/traffic/ph… x.com/DevinDVote/sta…
@CalgaryPolice @neufeld_mark I didn't know until now of this formal 12-month pilot while looking for more information related to my witnessing a cop nearly killed on Centre Street @ Samis Road on Sat night by a speeder who pulled over, then zoomed away.

@reportrix @MBellefontaine

cbc.ca/news/canada/ca…
@CalgaryPolice @neufeld_mark @reportrix @MBellefontaine I always knew Dreeshen's announcement, served in a "No Cash Cow" BBQ apron with Beef on a Bun for reporters, was colossally stupid.

I learned it kicked in on 1 April.

Will talk on record about my direct personal experience from this Saturday night.
