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.

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

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?

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.

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

Line Graph and Table of Total hospital admissions, ICU admissions, and deaths among laboratory-confirmed COVID-19 cases in Alberta by age group, 2024-2025
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.""

Likely untrue, despite the vagueness.

cbc.ca/news/canada/ca…
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.

Alberta is projected to have its worst influenza vaccine coverage since 2010-2011.

9 weeks into this year's flu shot campaign, we're at 19%. Last year, we were at 23%.

This whole season's coverage projects to 22%.
• last yr 25%
• 2011/12 was 23%

alberta.ca/stats/dashboar…Line graph of cumulative weekly immunizations showing at week 50 of this year's campaign (9 weeks in) 929,380 shots administered so far, which is only 90% of last year's 1,037,278 at the same time.
Line graph of cumulative weekly immunizations showing at week 50 of this year's campaign (9 weeks in) the coverage for all ages is 18.9%
Line graph of cumulative weekly immunizations showing at week 50 of last year's campaign (9 weeks in) 1,037,278 shots administered so far
Line graph of cumulative weekly immunizations showing at week 50 of last year's campaign (9 weeks in) the coverage for all ages was 22.7%.
Seniors 65+, at week 50, 9 weeks into the campaign:
• This year, only 49.2% coverage.
• Last year, 59.4% coverage.

LaGrange's arrogant, deceptive decision to cut off community medical clinics obviously figures largely in this drop.

cbc.ca/news/canada/ca…2024 vaccine coverage for certain ages at week 50, showing only 49.2% for age 65+
2023 vaccine coverage for certain ages at week 50, showing 59.4% for age 65+
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. Column graph of weekly flu shots administered, showing in week 42: • This yr, only 243,207
Column graph of weekly flu shots administered, showing in week 42: • Last yr, 330,264

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".

For free.

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

alberta.ca/release.cfm?xI…Screenshot of bottom of press release where you would normally see multimedia or backgrounder. Instead, "Related Information" only has  "map of proposed downtown elevated route".
1-page PDF with 2 maps on it - previous route and GoA proposal - that are so small and high level you cannot see the "map of proposed downtown elevated route" as touted in the press release link.
@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.

livewirecalgary.com/2024/12/13/pro… LWC has asked for a copy of the report done by AECOM for further review. A response has not yet been provided.  Calgary city council has also not seen the details, according to several councillors. City admin had apparently not seen the AECOM report before the province released details.  “We have not received the AECOM report before (Minister) Dreeshan ran to (Postmedia columnist) Rick Bell,” wrote Ward 8 Coun. Courtney Walcott via text.  In an official statement, the City of Calgary said that until council had the opportunity to review the report, including alignment and costing, they coul...

With PFC film members leaving Xitter, in last week's PFC, I promised to look into a shared calendar to potentially replace this Community.

Fiona (or anyone else we decide) can create a Google Calendar just for PFC, and share it with specific people.

🧵

support.google.com/calendar/answe…"Share a calendar with specific people" section from link.
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. "Control access to your calendar & individual events" table from link.
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.
