CBRN & S10/GSR

A question for the aficionados: while the S10 & GSR is great at keeping back the tear gas in a hut are their filters able to prevent virii passing through? Obviously contamination can occur from ill-fitting masks and bad drills BUT what is the efficacy of the filters for virii?
 
It won’t stop everything, Cyanogen Chloride (CK) a blood agent will destroy a canister in 30 minutes.

As for viruses they are minuscule and I suspect they would easily pass through a filter, but that’s a best guess.

Are you posting this from Wuhan?

Why not ask DSTL Porton Down yourself, after all nothing about CBRN protection is classified or anything?

The S10 was replaced by something else a few years ago, by the way.

I found a company that sells respirators which have filter canisters that are meant to deal with viral agents like SARS and Ebola:


The industry standard seems to be N95 filtration - it stops 95% of airborne particles, including viruses.

Nah for viruses you want a disposable paper mask like they issue here to escort suspected Covid-19 cases... I mean I feel so safe as the Doctors wear fuçking full Dustin Hoffmann monkey plague suits...

The GSR is 10000 times better than the S10 in terms of protection from airborne particules, and a secondary filter for biological contaminants, which is no secret, but I will not talk any more on that. It should, in theory, offer protection against viruses, however, as Dingerr said, there are agents that seriously deplete the protective properties of the system, and it makes no 100% claim against ALL contaminants, only those known and tested, and obviously, the GSR is only as good as the end user. Canisters still need changing etc
 
Just get your handkerchief out and urinate on it, then hold it over your mouth and nose.

It won't help at all, but it will make me laugh.

I assumed this question related to the Corona virus. For actual CBRN use then the respirator is part of a system including the protective suit, vaccines, medical treatment, defence against enemy delivery systems, and detterance.

In 1991 Saddam was deterred by US nuclear weapons - and did not use chemical or biological weapons.

That’s not a bad attempt at a regain, but it’s still an epic fail.

As long as the main mask is in a serviceable condition, then its the filter which is the important part. As long as its got at least a P3 code it should hold viruses out, as far as I can remember.
There are new commercial P3 filters with the nato 40mm thread available on fleabay or amazon, have a google.

They were talking about COV on Radio 2 t'other day and the efficacy of masks.

The Professors opinion was: If they think they have something people should mask up, and that in general to be useful a mask needs to be fitted to the user.

An old bloke called in with comment: He suffers from a chest complaint caused by his old job that results in severe breathing/lung problems if he is not wearing a mask when even just out and about wandering around town breathing in daily pollution. He wears an N99 mask made by Cambridge masks to military standards/specification.

Check out N99 vs. N95, they function and fit better.

Right, so a f uckload of ARRSERs will be walking about town in ressies, face veils, hankies, shemaghs, masks of all kinds, bags and bin liners with holes cut out for eyes, and all smelling of piss. We're gonna be loved aren't we?

A step up from this I suppose, though in retrospect the piss stains would possibly encapsulate and kill any random, airborne bacteria.

the smelling of piss will be nothing new for the more elderly and incontinent members of the site. ;)

These seem popular



Amusing yes but when you think about it, it is effective for some vectors, eg; a virus clinging to water (phlegm) particles in crowded, enclosed places such as trains or busses. I'm no expert but it seems that touch / contact with contaminated surfaces is the principle vector which combined with our habit of touching our faces a lot (2000 times a day on average) leads to an easy way in for the virus. Gloves and regular hand washing work well for this.

The other way in is the "air born" vector, the virus needs something to grab onto to transit through the air, dust particles and water particles. Most "surgical" type and dust masks will catch the dust and water in the air and the virus should be caught with it.

The obvious problem with this is that people will use the mask and gloves over and over and could contaminate themselves with a mask or gloves that caught the virus days or weeks ago. Disposal at regular intervals is important.

Her plastic bottle will provide some protection and while she looks ridiculous, it's better than being dead.

I may combine mine with a tinfoil fedora.

I've proffed a quantity of these 3M™ A1 Gas and Vapour Filters 6051 along with some full face respirators - just in case it goes to rat-shit... any good or should I flog 'em on fleabay and try and find some more filters for the GSR's that might have been left in a safe place i've forgotten about?

I like that, typical Asian ingenuity, fcuking excellent. When you consider people are wearing these when doing patient/infected handling it is damn fine.



I note that the kiddy is double masked too. I read something t'other day about soaking substandard, or already used face masks in a saline solution to make them more effective. Simply make a salt water solution, soak masks in the solution and then hang them to dry. If a gobbit of virus infected snot or phlegm coughed up by someone then hits your mask it dissolves the salt, this encapsulates the snotty gobbit and kills the virus. Simples.
