    To be sure add extra time to allow for heat to penetrate whatever material you are disinfecting or measure actual material temperature and start timer based on that.
    Thanks!
    Thatís useful and seems like it would do the least harm to the mask.

    While a modern mask might not stand up to it in the old days field hospitals boiled cloth bandages, sheets etc. and then hung them in the sun to dry. Potentially infectious materials were boiled to sterilize them.

    Here's a clue as to why professionals may run short on masks. The solution is obvious; if the fools who went out and bought large quantities would just release SOME of them to health authorities the shortage would be solved without needing special production.

    I have seen some people recommending using bandanas if no face masks are available though.
    Certainly better to nothing.
    I was talking about this next season of plowing, some of us wear a lot of hats. Machinist, farmer, rancher, and volunteer fireman to name just a few.

    I know you were.
    I wear multiple hats too!
    I miss working on my grandparents farm and definitely miss tractor time!
    If I ever end up owning a good chunk of land, Iím definitely going to get a tractor and a collection of bandanas :-)

    Exactly!

    One last question if you decided to share 1/2 of your available masks with a hospital, would they take them from a package that has been opened but the bag they are in has been closed most of the time? These were not hoarded but a couple of years on the shelf.

    The reason I ask is because unless you had them on hand for other purposes before this became an issue I'd suggest that panic buying leads to shortages for those who need them and while one box of masks might not seem like much when 10,000 people do the same thing supplies dry up fast.
    I have one of these RZ masks that uses a charcoal filter: M2.5 Mesh Masks - RZ Mask

    Took a bunch of chemo and radiation a year ago and they tell me my immune system is compromised, being close to sixty I think I might be one of the unlucky ones if I got it.

    Seems dryers are in the range of 125-135F (51-57C) so that might work given enough time. Maybe a spray with denatured alcohol first would help (let dry before the dryer!). Thanks.

    Yeah.
    Iíve been thinking of that also.
    I can understand reluctance from a hospital or clinic. Perhaps they can autoclave them or do the 80C for an hour bakeout sterilization.
    I donít have a good answer for opened packages.
    As far as my wife and individuals, it is better to protect them.

    Sterilizing with heat will probably destroy the elastic band. Saturate with 70% alcohol is what I have heard being done, until they disintegrate. In Oregon, the veterinarians have been ordered to give their PPE to the hospitals.

    Not just any mask will do, it must be insured for the task, liability insurance is a bitch. That is a big part of the supply problem. Supposedly that has been waived so the supply should pick up. The hit to the hospitals is just beginning, barely. In 2 weeks they are going to be way busier.

    My Dr. friend is pleading for the public to donate their n95 masks to Kaiser San Francisco. They are running critically short. Unbelievable what's happening right now.

    Being a tight wad farmer I use them again till the elastic disintegrates, I have tried to figure out how to tie on more elastic, but they break next to the staple and are too short.

    I do my part to ease the pressure on the supply chain.

    Maybe the EMS guys can use them, I will ask them, probably they are easier going than the hospitals and I can walk into the EMS barn and talk to the right person. Who knows at a hospital.

    FredC-

    I do know (from second hand but reliable source) that some local healthcare providers are observing a shortage of masks. My guess is the hospitals are burning through them for the acute cases and that's creating strains on supplies to the extent that it's even being felt by other front-line hospital workers (in addition to hording and theft).

    So using my common sense I will say that an opened case of masks with still individually wrapped masks is going to be viewed as far superior to working completely unprotected by any front line healthcare provider with a brain. Anyone sitting on that resource would be doing the system a solid to ask their local hospital if they would accept it.

    I personally would not use a completely open-package mask of unknown provenance. But if I had to treat a patient and my only option was unmasked or grabbing a sealed-package mask of unknown provenance even one that had been sitting around for a while...I'd use it.

    Cut an appropriately sized rubber band and staple it to the mask. I am only trying to reduce the dust I breathe so I will use one for weeks. I have a partial box of 3M N95 masks but they are 20 to a bag, not individually bagged. Purchased about a year ago, not a hoarder.

    SF should set up an anonymous drop-off center with no penalties and no shaming. Bet they'd get at least some of the horded ones.

    Woah woah woah. Letís slow this down.

    N95s ó you canít sterilize them. The technology to sterilize paper stuff is beyond the capability of the home user.

    N95s ó there is absolutely a shortage of these in the hospitals. I can verify this. Hospitals are taking donations. The laws around liability and Ďfor medical useí vs Ďfor industrial useí have been relaxed as of this past week. Hospitals are now allowed to purchase industrial N95s for medical use. If you know of companies with stockpiles available for purchase, please forward them along or post it here. If you need assistance with donations and you are in the northwest, please contact me.

    Politics ó please leave it out of this. I donít care if you vote red or blue. Healthcare workers cannot get masks and folks at the local supermarket are wearing N95s. Politics is the least of our problems.

    Somewhere there is an assembly line for these masks, how is it the general public can buy them before the medical companies can?
