⚠️ 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.)

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?

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.

@neiljshaw - — a few tips on your excellent article from a clean air advocate

"Consider Wearing a Mask" ?

No, "It is incredibly important to wear a well-fitting mask such as a N95, KN95, or KF94, for the best protection."

You two are doing Image
public health with this article.

Public health is best done with simple clear instructions.

No:
"These masks act as a barrier, reducing the spread of respiratory droplets when people talk, sneeze or cough."

Yes:
"These masks act as a HEPA air cleaner for the face,
cleaning the air of respiratory aerosols when people breathe, talk, sneeze or cough."

The barrier carries the idea of an immovable wall. Unable to be penetrated by things like oxygen and CO2 - which feeds antimaskers.

As an who debunks antimaskers, it is

As an anonymous clean air advocate, I've put a bit of thought into how to present, well, my expertise.

If someone were to say, "How do I know you know what you are talking about? Are you a doctor, or a virologist?"

To which, I would say...."No, but that's a good thing.
/1
I have focused on aerosol and masking science. Because it is those fields that give us the most information on how airborne particles, aerosols, get from Person A to Person B.

My expertise is derived from the great studies of Dr. Lindsay Marr, MacArthur recipient. Dr. Prather,
double National Academy member, Dr Milton, inventor of the Gesundheit, aerosol scientist and medical doctor; Dr Coleman whose group found that duckbill N95s captured 98% of emitted respiratory aerosols, and more excellent individual aerosol scientists.

I am not a fan of nasal sprays to stop The 'Vid, but I respect you having it as a layer in the Swiss cheese package.

But, some people have said they got bloody noses.

While at the ER yesterday, I picked up a pretty good at home technique. Let our $1,000 lay-out

save you money.

Use tongue depressors to make a nose pinch clamp.

Leave it on for 30 minutes. Still a problem? Two sprays of Afrin, and re-apply nose pinch clamp. Wait 30 minutes.

Still a problem? Cotton balls sprayed with Afrin, clamp, 30 minutes

Afrin- in generic form is $3.32 at Walmart.

Also, put a ice compress at the back of the neck, while doing the above.

"Cooling the nape of the neck is said to induce reflex constriction of the mucosal vessels of the nose"

A study demonstrated 100% PERFECT protection against SARS2 w/ readily available KF94s

✅ 181 HCWs
✅ 1 got SARS2 antibodies, but an epi investigation -> the infection happened elsewhere.
😡 The final checkpoint was March 2021. N95s only became freely available 1 month later
/1 FDA: N95 masks, now plentiful, should no longer be reused  By MARTHA MENDOZA and JULIET LINDERMAN  (Associated Press)  April 23, 2021 12:44 p.m.  Medical providers may soon return to using one medical N95 mask per patient, a practice that was suspended during the pandemic due to deadly supply shortages
What is described in the tweets
in the USA.

Korean study:
jkms.org/DOIx.php?id=10…

This is in comparison to a Swiss study during the same rough time-frame. A study which did NOT show the same excellent results, but dismal results. Why?

The Swiss had the same sort of fit testing,

pubmed.ncbi.nlm.nih.gov/35123572/ Results: We enrolled 3259 participants from nine healthcare institutions, whereof 716 (22%) preferentially used FFP2. Among these, 81/716 (11%) reported a SARS-CoV-2-positive swab, compared to 352/2543 (14%) surgical mask users; seroconversion was documented in 85/656 (13%) FFP2 and 426/2255 (19%) surgical mask users. Adjusted for baseline characteristics, COVID-19 exposure, and risk behaviour, FFP2 use was non-significantly associated with decreased risk for SARS-CoV-2-positive swab (adjusted hazard ratio [aHR] 0.8, 95% CI 0.6-1.0) and seroconversion (adjusted odds ratio [aOR] 0.7, 95% CI ...
PPE monitoring.

What was the big difference?

Are N95s/FFP2s inferior to KF94s?

No, it was supply - and other reasons.

Thread of debunking the myth that "babies should not be masked."

A baby uninfected is better than a baby infected.

If you oppose masking babies, you are immediately for infecting babies.

Let's get to it. A most excellent instruction page on how to mask babies.  Suck it antimaskers.
This solves an equity problem.

Not everyone has the money or technical skill to build a baby buggy PAPR.

Just like not everyone has the money to buy an adult PAPR.

Are you for people on SNAP being able to protect their babies? Or not?

Most can rustle up the money to buy some uber cute baby masks!

This is the link from the baby zine.

These need to be fit tested.

Now, let's get into the good stuff. The "OMG Laz has gone too far! We've got him!"

You better bring your A game.
