  1. Typically the expiration issue is straps and bands losing elasticity due to perishing.

  2. Oh hey guys, I JUST remembered… I have a stockpile of 55 million masks that you need

  3. Here’s out CDC’s guidelines, written 20FEB2020 on this issue of using expired masks during Covid-19.


    TL;dr Yes, they’re probably going to be fine, but they are no longer considered NIOSH-approved. If there are no other options use them.

  4. I bet they are glad they didn’t follow the Marie Kondo method.

  5. Would a hermetically sealed N95 package still be good after 17 years? Is there a reason it would go bad? Any science people here?

  6. This is why you rotate stock

  7. Better then nothing I would imagine?

  8. “We need more masks!”

    *Snaps fingers* “Wait, didn’t we get a metric shit ton last outbreak?”

    “Yea, we certainly wouldn’t get an imperial shit ton.”

  9. Going to chime in here as a filter engineer. Masks are likely a meltblown polypro or polyester. They last a LONG time as long they not, say, stored in direct sunlight. I don’t know about expiration dates for such things, but even after they start to physically degrade (see the dust!) they would be very effective for this purpose, and certainly *WAY* better than nothing. Even if you have to jury-rig new elastic.

  10. Stockpiling was smart, but in retrospect, should have been rotated out as expiration was reaching its date. Can’t blame them, so lesson learned moving forward

  11. CANADA. We will show the world how we can come together and defeat this. Excluding all of those idiot parents letting their kids play on playgrounds and having to have to go on that coffee date.

  12. It sure beats washing a dirty one to re-use, as President Trump has suggested.

  13. Considering I’m a health care worker re-wearing a single use N95 mask over and over so I can hopefully keep myself and my clients safe from coronavirus, I say just use the fucking masks there’s nothing wrong w them.


    An actual health worker.

  14. The masks themselves should be in good condition. The main breakdown is in rubber and elastic parts such as straps. UV exposure is also bad so hopefully they’ve been stored in the dark.

    Old masks are better than no masks.

  16. The way I see it, a less effective mask still beats no mask

  17. WOW if this is true then well fucking done.

  18. CDC/NIOSH believes the following products, despite being past their manufacturer-designated shelf life, should provide the expected level of protection to the user if the stockpile conditions have generally been in accordance with the manufacturer-recommended storage conditions and an OSHA-compliant respiratory protection program is used by employers. In alphabetical order, these models are (manufactured between 2003-2013):

    3M 1860
    3M 1870
    3M 8210
    3M 9010
    3M 8000
    Gerson 1730
    Medline/Alpha Protech NON27501
    Moldex 1512
    Moldex 2201

    N95s that are past their manufacturer-designated shelf life are no longer considered NIOSH-approved, as all manufacturer-designated conditions of use must be met to maintain the NIOSH approval.
    In times of increased demand and decreased supply, consideration can be made to use the N95s listed above past their manufacturer-designated shelf life when responding to COVID-19.

    This preliminary information from the NIOSH study suggests certain N95 models beyond their manufacturer-designated shelf life will be protective. CDC recommends that N95s that have exceeded their manufacturer-designated shelf life should be used only as outlined in the Strategies for Optimizing the Supply of N95 Respirators.

    Reports detailing the performance results of stockpiled respirators sampled from stockpile facilities are available on the NIOSH webpage.

  19. Doug Fords gonna sell em on Amazon to NY and use the money to buy a Casino.

  20. N95 masks have a shelf life of 8 years. Source: Worked at Crosstex International, a medical supply manufacturer.

  21. The people in the Ontario government who ordered these are looking like geniuses right about now.

  22. It’s only the rubber straps that can degrade from age or exposure to sunlight. Not insignificant since the mask needs to fit tightly to your face, but pretty easy to tell if it’s OK to use or not. Good chance most are useable, and if not, you’d think they could rig new rubber straps easy enough.

  23. I work at A major hospital in Toronto. I got an email from my boss this morning (and he never emails on weekends) that I’m gonna be tasked with repairing PPE next week. He might have been referring to this, but I guess I’ll find out tomorrow!

  24. They’re expired and the elastics often break.

    Source: Wife is a doctor and has used them. Many elastics broke.

    Also, no government allocated funds to *manage* the stockpile. How you manage it: you bring in the new stuff and distribute the oldest stuff. Sort of like how you put the new milk at the back of the fridge while you use up the stuff you bought last week. Basically the masks sat in storage for 17 years. Fucking stupid and awful.

  25. Everyone’s so concerned about the elasticity, hell, stick a clean one *under* the one with good elastics… geezus, duct tape it to your friggin face if you have to.

  26. What’s the worst that could happen if they are expired

  27. Usability? How about “better than nothing!”

  28. I’m going up the attic to see if I have any stocks of useful stuff in my house.

  29. Dug up one of my old emergency kits from my basement the other day and sure enough it had an N95 mask that was 5 years out of date. Apparently those masks do degrade over time. However, a degraded mask is still better than no mask at all.

  30. they should really have a procedure of cycling them through the hospitals or something before the expiration and purchasing to keep the stocks up

  31. German military is doing something similar. The masks are out of date so they need to be tested one by one. Testing one masks takes two people 12 minutes. You need 2 million people working a 10-12 hours shift one day to test 55million.

  32. Considering medical staff globally is going without masks or reusing masks, in many cases, I’m guessing an expired medical mask would be better than what they have now, which is literally nothing at all in some cases.

  33. That’s like 45 for each person in Canada.

  34. “Hey guys, guess what I found!”
