PROTECTIVE MASKS AKA GAS MASKS

[LetFreedomRing 5,754]

Protective Masks will protect you from airborne gases, liquids, dusts and contaminates that must be breathed in or get into your eyes to affect you.  Are you likely to need one?  Are you likely to need any of the gear you currently have or stockpiling?  It sure is nice to have if you do need it especially for the budget minded cost and effectiveness of this particular model which I have chosen for myself.  This is also effective against CS aka tear gas which is used in people control such as a possible Red Flag raid.

I have looked into gas masks a little bit on line and comparing units.  One kind did mention nuclear particles.  I thought this was a great idea as someone could set off a nuke upwind of you and force you to breath through a mask for some time.  Is this mask nuclear rated?  

 

My local military surplus store has a whole section of military gas masks.  I guess I will have to write down each name and type and try to check them out on line.

I agree and would highly suggest getting one rated for NBC, Nuclear, Biological, Chemical and make sure the filters are as well.  The Israeli M15 above is rated as such.  It will use the Israeli filters or any filter with a standard 40mm thread like the NATO filters.

...... I heard that surplus gas masks are actually bad because they have most likely been on the shelf for a long time, usually past their expiration date, which apparently gas masks and their attachments do have, oddly..... And best to get an American one because an Israeli one is in another language and that if you do not use your gas mask properly, you can get sick and even die..... Ditto with getting a Russian one for the same reason, as well as because the Russian gas masks have asbestos in it.... ? But was informed that as far as getting a surplus gas mask goes, that it's better than getting no gas mask, but surplus is not recommended, supposedly.... And that it should be an NBC gas mask, I think it's called. ? Nuclear, Biological, and Chemical.... I just need it for the chemical part, like for riot police attacks like the spray that they use and stuff like that.... Are there any such masks that you recommend for that??

This claims to be rated for gas so it should actually be effective against CS / tear gas.

Thanks, @ LetFreedomRing !! But it says that it is for costume purposes, according to the reviews, and to avoid if using it for actual gas mask purposes.... ;/

You can find a bad review of any product as anything man made can eventually have a production or quality control problem.  What is more important in the rating system is what the majority of the reviews and ratings show on average.  Also there are differences in surplus items.  There is surplus used damaged or undamaged, surplus new but close to or past recommended usage / expiration dates, and then there is new surplus that is within recommended usage and expiration dates or recently manufactured.  The mask I purchased and posted about in the beginning of this thread is new surplus recent manufacture from where I purchased it and well within recommended usage dates.  All of these things need to be taken into consideration when buying surplus items.  Simply being surplus is not an indicator of itself that something isn't good and still useful for it's purpose.  The most important thing of all about any mask is the filters, that they are within their expiration date.  As long as the filters are good and the mask isn't damaged and fitted properly, it should work just fine.

The proof of the mask is in the breathing.

So ... why not test your mask?

 

These people give a recipe for making homemade tear gas: https://www.wildernessarena.com/supplies/weapons/how-to-make-homemade-tear-gas

I haven't tried it. I can probably get a good substitute by having a meal at my local Indian restaurant and ordering the vindaloo curry.

@ Doug1943 , Do physical stores actually sell gas masks, or is it only online stores??

All the NBC filters I've been able to find have 'P100' particulate filters, which are just as effective (against particulates) as the dust filters you can get for construction grade facemasks at Home Depot/etc. They do not filter out viruses, per say. IIRC, the average virus is about twice as small as the particulates P100 is rated to filer out. From what I've been able to determine, any filter that could reliably filter particles as small as viruses would require powered ventilation, as human lungs would not be strong enough to draw sufficient air through it.

That being said, P100 will still filter out (or at least slow down) some virus, which makes killing what does get through easier on your immune system. Also, few viruses survive very long outside the human body, and its likely a filter that at least delays the virus getting through will help kill them with time before they get through. Also additionally, some viruses can only survive in human mucus (such as sneeze spray or human waste), and the filter will stop those particles from getting through. So a P100 filter is lightyears better than nothing, just not a guarantee.

My (theoretical) solution to improve the virus prevention ability of filter masks is you build an inline silver mesh (I'm thinking an additional screen made of a wad of silver chainmail) or a UV light exposure chamber (UV light in the spectrum of 240-280nm is what is used in/on medical equipment to simulate the anti-microbial properties of sunlight). Most of the UV lights you can get as flashlights and such are not within this range, and will either be less effective as an antimicrobial or not at all. Generally speaking, if it doesn't advertise the spectrum, its going to be in the high 300's, and I wouldn't rely on it to kill anything unless I had nothing else. If I had to guess, I'd say if it can give you a sunburn, it will kill viruses, and if not, it won't.

Just food for thought, really.

You may be on to something!  Hey, if I had a few million dollars handy, I'd hire a qualified medical researcher to examine the feasibility of your ideas, and then, if they looked viable, fund a start-up anti-virus mask company.  Although probably some other b*******d has thought of it first and is ready to begin production.

If so, no one has put it on the market yet. I looked

I bought a handful of medical grade UV LEDs that I'm gonna build something with (they aint quite cheap!). I just don't have the resources or know-how to test it.

I think viruses, as opposed to bacteria, are hard to study outside of very specialized laboratories. You can cultivate bacteria, or see if this or that method keeps them from growing, but

viruses are another matter.

I did a quick scan to see if anyone else had thought of incorporating UV into a mask and came up empty, but that was just a Google search.  Later on I'll look on JSTORE, the database of academic papers, and see what I come up with.  (If you come across a paper that looks really good but is behind a paywall, I might be able to get access to it via  my academic account with JSTORE.) In the meantime, these links are interesting:

Here's the email of an Australian medical researcher re. masks and viruses  - she co-authored one of the papers above; the address is 10 years out of date, but it can't hurt to email

her and raise the idea of a UV-filter in a mask. What with progress in miniaturization, and longer-life batteries, something that was not practical ten or twenty years

ago might be practical today.

I wonder how much trouble/expense it would be to get a patent on the idea as quickly as possible? https://en.wikipedia.org/wiki/Patent
