⚠️ 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
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."

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.

If you are Covid Aware you have probably been avoiding the dentist. Well, the dental studies have come to you.

This edition? #CovidAwareSoReducingDentalVisits - Water flossing (WF) edition.

Or, as I like to think of it, the Gum Salon.

Thread.
Flossing is necessary for those super tight contact points as you see in the above thread, and is great to remove plaque down 1 mm deep in the gum line (gently).

InterDental Brushes are fantastic and go down 2-3 mm into the gum line to remove plaque.

And WFs in general, are, well, amazing!!

They basically go back and forth with InterDental Brushes on which is better as far as being the top of the food chain for overall cleaning of the space between your teeth.

But.

If you have gum recession, you may have this Image

#CovidAwareSoReducingDentalVisits - less mouth open = less 'vid risk.

I am a GREAT flosser. My family thought we had genetic gum disease.

Below we can see rubber stick on the left, floss on the right, and a InterDental Brush (IDB) in the middle.

See the problem?
/1 Image
A couple more example pics on why I am sick to my stomach thinking of all that money wasted.

We THOUGHT we had great dentists. Not a single one mentioned IDBs, and how the bristles allow all interdental spaces to be reached.

And it gets better!

/2 Image
Image
IDBs actually reach down in between the gum and teeth - 2-3 mm. Floss? Only 1-2 mm.

As plaque grows down into and touches your gums, that's what causes them to get inflamed - and begin to retreat (very simplified).

If you brush that space? Problem solved.

/3 Floss, Interdental Brushes, and Waterpics Use all of them - floss works great for those narrow spaces.  Interdental Brushes (IDB) work great in larger spaces.  Waterpics work great immediately after eating, as you want to wait for an hour eating acidic/sweet just like regular brushing.  It is a mistake to NOT IDB.  Multiple studies indicate IDB is good, including this RCT where IDB was better than flossing (free version - great how to brush) - with people with chronic periodontitis.  Students found IDB to be better.  But IDB is better than rubber picks is better than floss.  IDB way better ...

Covid Aware Teeth

The Calcium Lactate Rinse. Cheap, super easy to do - and it really enhances your fluoride uptake to re-enamel your enamel.

It's just not very well known, despite being very well supported within studies - and very cheap.

Mix 1/8 tsp with 1 oz water. Shake
thoroughly, till the granules disappear. Takes a few or 20 shakes, then just wait. Rinse for 1 minute. Spit out.

Immediately brush with fluoride or fluoride rinse.

There might be a better powder

1/8 tsp

I use the same 1 oz shaker as my stannous fluoride rinse comes in.

(That fluoride rinse was $4 cheaper at my dentist than this $24.

My Prevident 5000 ppm actually did not need a prescription - if bought from my dentist, as a couple of side notes.)

.On the one hand, we have study after study showing 36% or so rate of LongCovid.

On the other, we have the WHO saying the rate of LongCovid is only 6%.

I got curious. What drugs are the WHO smoking - and can I get some?

🧵. Image
My 36% comes from the latest massive meta:
eatg.org/hiv-news/more-…

But what about that 6%?

Turns out it's this old chestnut from 2022.

And there are such major players on it...so many I can't even screenshot them all.

But I fear no title - and neither

jamanetwork.com/journals/jama/… Image
will you.

The problem with this 6%? There are 200+ symptoms in the LongCovid symptoms constellation.

This study focuses on three clusters.

Which is incredibly vague, which is normal for the WHO.

So, after digging through the f***ing supplement, there are a few symptoms Image

COVID is as transmissible as measles?!

"BUT, BUT, measles can infect up to 90% of people they are in contact with!"

So can COVID.

Time to wake up. The lecturer tried to promote sales of a flax oil product, and many elderly people were lured to attend by the promise of free eggs, Xinhua News Agency reported.  He gave three lectures on Jan 10 and 11 in a Tonghua classroom while not wearing a mask, with each lecture lasting about 2.5 hours. A total of 97 people, most of them retirees, attended the lectures in a classroom whose doors and windows were closed, the China CDC report said. The lecturer went to a pharmacy at noon on Jan 10 due to muscle pain and other symptoms, indicating he was likely at an early stage of the disease then, it ...
So, some will be pushing back - always welcome, albeit this is anticipated.

Rnaught is just an estimate.

The famous measles 12-18 is shown below.

But the R0 of 6-8 has the most estimates.
