⚠️ PFAs from 3M ⚠️

🤬N95, N100, PAPR.🤬

Just found this, so giving you a heads up. Source at end.

On a personal note, I know some of you have some of these, and I am both sorry and livid for you.

P100s have PFAs.
( I have a rack of these.)

/1 Image
PAPR - Versaflo, Powerflow. Read for details.

/2 The 3M™ Versaflo™ TR-300+, TR-600, TR-800, and Powerflow™ PAPR motor blowers contain PFAS in certain blower housing components to help manage heat and seal the circuit board, as well as lubricate the motor. This motor blower is sold by itself, as well as in kits where it is paired with multiple breathing tube and headgear options. Some products utilize lithium batteries which may also contain PFAS. The 3M™ Versaflo™ Breathing Tubes BT-20S, BT-20L, BT-30, and BT-40 which are used in certain powered and supplied air system configurations to connect the headgear to the air source, use a...
JFC. 3Ms R, P, and HE filters.

@3M. P100, you greedy jerks?

@NIOSH_TWH @NIOSH - you realize we are going to FOIA you, right? I know you guys read my tweets, so let's get this fixed?

/3 Image
3M’s 7800, 7800B, FF-400, and FF-800.

(I huffed PFAs with P100s, and dodged the bullet on this one so far, as I have the 6800.) In addition, 3M’s 7800, 7800B, FF-400, and FF-800 Full Facepiece Reusable Respirators contain a speaking diaphragm that is used to help provide easy communication for the wearer to those around them. This speaking diaphragm contains PFAS. The FF-400 and FF-800 respirators also have a coating that is applied to the facepieces’ polycarbonate lens to allow for improved paint and stain resistance for easier cleaning. This coating contains PFAS.
@3M - it's the science of poison, not fluorochemistries.

Did you come up with the PR campaign for @DuPont_News's Teflon, the Happy Pan, as well?

Greedy bastards.

Source for all of this. I almost skipped this because I knew the firefighting gear was contaminated. But thought it was a little long for just one product.

multimedia.3m.com/mws/media/2303…
Back in 2021, Sean Lynch of @3M said that surgical respirators did NOT contain PFAs.

Which sounds like a lie as they are EXACTLY what would work good with PFAs to repel blood, etc

But he DID say that some models of their STANDARD N95s may contain some PFAs in the headbands. Image
So, at least the PFAs is not in the filtration? But it is concerning that only 3 years later, their PFA document does not mention N95 headbands.

Did they get rid of the PFAs so quickly? When they are not required to until 2025 (and only piecemeal).

eenews.net/articles/face-…
And, of course, this was in 2021 and 2023, long after 3M supposedly began to phase out PFAs in 2000.

Which was touched on in their testimony declaring minimal health effects.👀

I have been a fan of 3M products, and now am a tad shocked.
pfas.3m.com/3M-to-share-re…
Image
And the trust is gone.

Anyone have the ability to test Filtrete 1900 for PFAs? 👀 Image
Want to help light a fire under 3M?

Hit their chat up on Monday and ask about your favorite 3M respirator to see if it has PFAs in it.

See what doc they provide you. Let's compare notes

And absolutely great point about all of the respirator companies.

Please reply back here what you hear, try to get some sort of formal document.

Also great point.

But my stance is that I want to avoid them as much as possible.

Just like Covid.

There was a study on the #corsirosenthalbox that showed reduction of PFAs through using the box.

Went back and reread it.


The box in question used Jim's TexAir filters.

Here is a link to his filters:
pubs.acs.org/doi/epdf/10.10…
texairfilters.com/filters-for-bo…
Image
Here is the article that covers the PFA study that will be easier to read for most.

To clarify- we don't know if 3M filters, Filtrete 1900, have PFAs or not. But are pushing to get them tested.

I personally have 8 of them where I am living, and I am not
brown.edu/news/2022-12-2…
tossing them until someone does test them.

If I need to replace a set before they are tested or @3M replies? I will be buying Jim's filters based on that study.
And here we go.

@marigoldglitter showing the way by hitting the PPE company annual report.

PFAs in the majority of @DraegerNews products. So, Dragger....got PFAs in your respirators? If so, where?



Image

Thank you @profahnhmc!

I've uploaded a copy to Google sheets. Anyone with this link can open it. NO write access granted.



Let's do an example - Aura. Pay attention, please, as I am not going to look up everyone's respirator.

docs.google.com/spreadsheets/d…
Click on 3 dots (the hamburger).
Click Find and Replace.
Type in aura OR the respirator number. To the right in tiny writing it shows 1/1.
If more then 1/2, click on little arrow to jump to each one.

Sorry, folks, we can see the 9211+ Aura is right there.

Scroll to the right


Image
Image
Image
Image
Columns D- F. Labels below.

Aura, 9211+ has "0.01 - 1%" as the "(#1) % PFAS Range"

F029-Flame retardant is the purpose.

Notice Column D?

That is "Date Product No Longer Contains Interntionally-Added PFAS (Reformulation/Discontinuation)".

The blank line means nothing
Image
Image
scheduled. I am sorry.

Not done yet.

Scroll to the right to column K, and check for another vendor, which is the second vendor involved.

Q is 3rd.
W is 4th.
AC is 5th
AI is 6th
AO is 7th

I presume that if there are multiple vendors, they fill in from the left. Image
Let's check for the Aura 9205.

After clicking on the down button, no 9205 is on this list by either Aura or 9205.

Neither is the 9200, the 8511, the Vflex 9105.

One caveat - it appears that 3M is in the process of discovery. The language used is careful to say they may add


Image
Image
Image
Image
more.

An script could be written to check on the most common respirators and alert if one is added. Just in case someone is feeling frisky.

Went to look for the 6000 series.
Tried 6000. Not clicking 2,070 times.

7000001934 is the MPN. It is NOT ON THE LIST.
Image
Image
So, does this work consistently?

I check the Secure Click FF-802. Yes.

So, if you get too many results look for the "MPN" on web sites. 3M calls it the "SAP Product Code", column B.
Image
Image
So NOT ON THE LIST
6800 elasto,
8511
9200
VFLEX 9105

ON THE LIST
Aura, 9211+

HF-800 secure click not on the list - but many of the filter cartridges are. ("Secure Click").
I WILL NOT BE LOOKING UP ANYBODY'S RESPIRATORS.

Please do not ask me. Please ask each other. Please help each other.

I have not eaten breakfast due to pounding on this, and it is 5 pm.

Waffles for dinner because why not.
@crwequine Just added to the thread how to check the 26K long list of products.
How the heck did @profahnhmc spot this?

Bravo!

(pfas.3m .com/ pfas_uses ) -shove those words together.


contains the sentence "To learn more about 3M products that use PFAS*, click here."

Great interview of Ed Yong - I am just covering the C0V1D part.

/1 The Interview Ed Yong Wants to Show You the Hidden Reality of the World Ed standing with his arms folded. His eyes tell you COVID is not over.
You've been clear in saying that C0V1D has not gone away. You ask people to wear masks at your events..... You’ve been clear in saying that Covid has not gone away. You ask people to wear masks at your events. But that attitude is not necessarily where the rest of the world is. How do you think about continuing to take precautions and advising others to do so when it feels as if society has moved on? I do it for a bunch of reasons. Firstly, I have learned that I enjoy not being sick. I know that the cost of long Covid is real and substantial, and I don’t want to run that risk lightly.
"I think it makes a huge difference to them to have the person at the front of the stage wear a mask. It tells them, It’s not weird." . I also know that I have many friends and people I’m close to who are immunocompromised. So for the sake of the people around me, I also don’t want to get sick. When I do events, I wear a mask for those reasons, and because I know that every time I do a talk, while the vast majority of people in the audience have probably moved on, there are going to be other people who haven’t. I think it makes a huge difference to them to have the person at the front of the stage wear a mask. It tells them, It’s not weird. So I do it for that reason, too. In terms of holding this line at a point when a l...

I am sorry if this will upset you. A lot of people depend on NASAL SPRAYS for C0V1D.

I have been iffy on them, but viewed them as "if they don't hurt, why not" but not for me.

There's an analysis
on Reddit that you should read in detail, and make up your own mind.
/1
Here is the link:


Here is a 4 tweet TLDR version.

Here is how it starts - the author goes HARD at the underlying studies. reddit.com/r/ZeroCovidCom…There is no convincing evidence that nasal sprays prevent COVID-19 There is a lot of misinformation out there about nasal sprays preventing COVID-19. Unfortunately, there are no convincing studies showing that nasal sprays prevent COVID-19. The published studies investigating whether or not nasal sprays prevent COVID-19 each have major issues, which I will detail here. I have a PhD in biochemistry and one of my PhD projects was on COVID-19. The main takeaway of this post is that there is no sound evidence that nasal sprays prevent COVID-19. Thus, nasal sprays should not be used for COVID-...
Some pretty harsh language, but to me the important thing is we still have clean air.

Which is good, because it boils down to only 2 studies saying that nasal sprays work, per them. 5. Summary/TLDR and final thoughts Unfortunately, many people including covid influencers have fallen for the grift of nasal sprays preventing COVID-19. Some such influencers have promoted these nasal sprays for free and helped spread the misinformation that they prevent COVID-19. Unlike with nasal sprays, there is ample, sound evidence that high-quality well-fitting respirators, ventilation and air purification prevent COVID-19. The human clinical trials testing whether or not nasal sprays prevent COVID-19 are garbage, and to my knowledge there are only two! Please don't lower your covid...

Guillain-Barre Syndrome linked to poultry eggs? H5N1?!

The BBC had a good article from February 3 that talks about how these Indian states' cases are linked to campylobacter jejuni, a bacteria. It IS the most common root-cause, globally.

And IT is commonly found in poultry. AVOID CHICKEN AND EGGS RIGHT NOW SIGN showing for the country of India in a tweet from @alwaysmadesh. Due to Guillain-Barre Syndrome.
"Campylobacter jejuni infection is the common associated microorganism (25–40%), followed by cytomegalovirus (6–15%), Mycoplasma pneumoniae (3–21%), and Haemophilus influenzae (1–9%)"

BTW - Cytomegalovirus is also an airborne virus - that just happens to cause brain cancer.
Mycoplasma pneumoniae - also airborne.

And...drum roll please...Campylobacter jejuni also airborne.

Don't get me wrong - jejuni most definitely is also fecal-oral, no question.

But it's also airborne.

Sampled from the air below. Figure 7. GCN/m3 results using microorganism-specific primers. These microorganisms were chosen for their pathogenic and opportunistic nature. Samples 1–12 indicate the WWC collections in House A, 1R–12R the WWC collections in House B and 1F–12F the filter collections in House A.

Just a little bit closer to acknowledging H5N1 is airborne.

3 vets asymptomatic, + for bird flu antibodies. Did not wear respiratory gear or glasses.

Did wear gloves and coveralls - so rules out fomites.

One practicing in states with NO H5N1.

Vets get very close to /1 No seropositive practitioner knew that they were working with dairy cattle with known or suspected HPAI A(H5) infection. None of the seropositive practitioners reported wearing respiratory or eye protection while providing veterinary care to cattle. Neither respiratory or eye protection is recommended when working with uninfected animals in regions without confirmed cases; however, safety goggles and a respirator are recommended when working with uninfected animals in regions where there are confirmed or potentially infected animals (4).
Among 150 bovine veterinary practitioners, three had evidence of recent infection with HPAI A(H5) virus, including one who only practiced in two states (Georgia and South Carolina) with no known HPAI A(H5) virus infection in cattle and no reported human cases (1,2); this practitioner reported no exposures to animals with known or suspected HPAI A(H5) virus infections. These findings suggest that there might be HPAI A(H5) virus–infected dairy cattle in states where infection in dairy cattle has not yet been identified, highlighting the importance of rapid identification of infected dairy cat...
aerosol sources. Aerosol orifices.

This lines up with previous studies.

Latest Pew Poll.

Or an exercise on "How well did Biden disappear C0V1D?"

On one hand, 21% of Americans still view C0V1D as a major public threat 21% of Americans still view COVID as a major public threat.
On the other hand, still masking?

6% of Democrats
4% Americans
2% Republicans

Guess when Biden took over on the graph? On the other hand, still masking? 6% of Democrats 4% Americans 2% Republicans Guess when Biden took over on the graph?
Yes - pretty much as soon as Biden took over, he began disappearing C0V1D.

BTW, the last poll was by yougov - masking was at 12% last year. On the other hand, still masking? 6% of Democrats 4% Americans 2% Republicans Guess when Biden took over on the graph?

What do we need to do to make every healthcare worker in the world understand that flu is airborne?

Get IPC on board.

Let me introduce you to Dr. Zahir Hirji, President of @IPACCanada at #IPAC2023.

Where do we know him from?

That's a very interesting question.

/1 Image
In 2006, Dr. Tellier wrote an article in the CDC EID explaining that influenza was airborne via aerosols.

Quite nicely done.

pmc.ncbi.nlm.nih.gov/articles/PMC33…
Dr. Zahir Hirji and some other IPC doctors from the Canadian HUGE University Health Network disagreed.

Right back you, Tellier - in 2007.
