⚠️ 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.

How do we know TB is airborne?

71 guinea pigs gave their lives between 1956 and 1958 in the eponymous study by Riley et al, getting TB air piped in from some TB patients, to prove TB is airborne.

Influenza is kind of airborne per most doctors. But kind of not.

So....

We need some volunteers.

Will horses be those volunteers that finally lay it all out?

Yes - but none of them lost their lives.

Air samplers were deployed and tracked horses inoculated with Equine influenza virus (EIV).

From the very first day post inoculation (dpi), until the Image
12th day, EIV was found in the air, in this new study.

With no horses, or guinea pigs, hurt in the process.



But sure, influenza's not airborne - if you are the USDA, right, @nirav_maine?

Of course, yet another new study points an accusatorysciencedirect.com/science/articl…

Thank you @BarryHunt008 for flagging this.

@ThailandMedicaX, retweeted by some because of their controversial takes (ahem, their lies?), is saying that FAR-UVC is dangerous because somehow the light will get into the lungs.

Lol.

They are just apparent supplement grifters.

I noticed they were using @NukitToBeSure's excellent torches as their example picture.

Strange to be so selective of an example picture for someone purporting to be an independent news source on health.

Hmm. I helped defend Nukit against charges of Image
racism by a very nasty couple who it turned out just do not like UVC, personally. I wonder....

Yep, ThailandMedicalX has blocked me.

But, it's weird for a purported news source to block someone like me @gorskon

And them blocking me, is probably because Image

You've heard of "The Three Problem." - great book, and excellent Netflix series.

If you want to be avoid catching Covid, you probably have "The Empty Room" situation in the back of your mind.

How long after a room had people in it, can you safely demask?

Measles was thought to be airborne after a child caught measles an hour after the infected child left the same office.

.

Interestingly, you can see the reluctance in blue below to call measles airborne. Much like the WHO with @mvankerkhove researchgate.net/publication/19…In February 1981, a measles outbreak occurred in a pediatric practice in DeKalb County, GA. The source case, a 12-year-old boy vaccinated against measles at 11 1/2 months of age, was in the office for one hour on the second day of rash, primarily in a single examining room. On examination, he was noted to be coughing vigorously. Seven secondary cases of measles occurred due to exposure in the office. Four children had transient contact with the source patient as he entered or exited through the waiting room; only one of the four had face-to-face contact within 1 m of the source patient. The...
which spent millions to rebrand SARS2 as "through the air" rather than airborne.

It is an inconvenient truth that then leads us to the study showing an #EmptyRoom SARS2 infection at 1 hour and 43 minutes, and FOUR HOURS and FORTY-FIVE MINUTES.

In this study, it comes with Experimental evidence suggests that SARS-CoV-2 remains viable within aerosols with a half-life of approximately 1-3 hours, though changes in aerosol microenvironment may shorten viability to minutes. However, it remains unclear how long airborne SARS-CoV-2 can transmit infection. Whole genome sequencing of nasopharyngeal samples obtained from patients on an outbreak unit suggested in-room transmission of the delta variant, AY3 lineage, of SARS-CoV-2 to two patients admitted 1 hour, 43 minutes and 4 hours, 45 minutes after discharge of an asymptomatic infected patient. These findings suggest...

Mum's the word - if @SecKennedy is Mum.

You see, I have been a VERY FOCAL CDC critic. But you can't criticize without listening.

And I have been noticing that that the CDC has been very, very quiet.

NPR noticed as well. Image
This is crazy. Image
Yes, the @CDCgov has been deathly quiet.

90 times last year, versus 4 this year.

This is not MAHA.

This is MASA - Make America Silent Again.

And as one of the CDC's most focal critics? We NEED them to be sharing Public Health information. Image

Fit factor of 250- 4000 versus the normal 100-200 for an N95? Where do I sign up?

Oops, that's here. With me. Starting a build with an Ebay'd Bullard EVA PAPR's filter - and some DIY loving goodness of a heat gun and PVC pipes.

The benefit of this build will be the over 10
hour run-time of the massive battery on the PAPR.
Got a long dental appointment? This will be the answer.
