I had to stop as pedestrian lights in Essendon while I was driving on Friday. A woman crossed the road in front of me wearing a mask tied over her face. When she was walking directly in front of my car I noticed that I could see right through the mask from one side to the other. It was touching above her nose and under her chin but the sides were right away from her face. Not sure what it was achieving.Quote:

Most of my postings regarding masks in the dust forums would indicated I don't think much of their efficacy at preventing airborne bits from getting inside you and I also maintain this position with regards COVID19. However, with wood dust it matters little whether we touch our faces or not. Also wood workers don't need to signal/remind everyone else around them "hey right now we're in a dangerous environment".
Most of the problems with antibacterial masks are over use which let's then get soggy, saggy baggy and dirty. The way around this is to replace them but we can't afford to do this right now. Hence it may well eventually come down to rolling our own.
Just like wood work I think clean antibacterial masks for someone without symptoms are a last resort after doing everything else. When I have to go the GP next week am I going to wear a mask - you bet. But I will also wash my hands before and after, change and my clothes when I get home, carry and use hand santizer, sit well apart from other patients in the waiting room, and by wearing a mask this could incentivise other patients to keep away. Do I wear one at home - nope.
Just like woodworking the issue with antibacterial masks is too many users treating them as silver bullets.
The odd slight cough or two and clearing of the throat will keep them away, particularly if you are wearing a mask.... :;Quote:

I have a 3M silicon P2 mask (and a couple of new ones in packets) that I use for dusty jobs like sanding, changing dust bags, fireplace cleaning etc, but I also have a box of 10 disposable P2 masks with exhaust valves that I bought a few years back. The silicon masks will keep out cat farts and ammonia smells because they are an excellent fit. I'm wondering if I can disinfect the disposable masks by spraying some metho on them? It shouldn't leave any residual should it? Same question for the silicon masks.
Yep metho spray and then hang the masks outside in full sunlight for some added UV treatment.Quote:

Errr, well, actually, on the day it wasn't the cat...it was me after a particularly nasty curry :B. But I have cleaned up an even nastier cat's mess with no blow through.Quote:

I have some reservations about the efficacy of face masks. Bob has already alluded to, actually stated, some problems. That related to the fit of the mask and the mask's longevity, which is not very long at all. One particular aspect that has not been touched upon, unless I have missed it in which case I apologise, is that the mask should not be touched with your hands. This is the WHO's recommendations on face mask usage and application.
When and how to use masks
I would be surprised if more than one in ten people comply with all those recommendations. I am guessing, completely, that some would be worn until you can ring them out. :oo:
Realistically I think you would only be able to use the same mask for one day. That in itself would be a huge demand for masks. I would be surprised if there were the resources to cope.
One final comment on the hygiene aspect is that detergent and/or soap and water seems to be as effective as killing the skin borne germs so are we over-thinking with the santiser option? Perhaps we are talking convenience with sanitisers, but realistically, for many of us, how much are we going out and about in the current climate?

This is a link that summarises the nature of the illness based on what has already happened, mainly in Wuhan. Interestingly it reflects much of what has been discussed on this thread. Has The Conversation been reading our Forum? :)

The HUGE demand by all sectors of the population is why the DIY masks has kicked off. The DIY movement also reduces the drain on use of real masks by plebs so they can be used by the medical community.Quote:

For the general population that are not infected the efficacy of any mask is more in its appearance and reducing hands touching nose and mouth so these can be cleaned and reused.
There is lots more than DIY masks going on
My son is working with a local paediatrician on a DIY face shield for doctors using a 3D printed head band and a replaceable clear plastic shield.
An easy way to re-use tight weave cotton fabric masks is to soak then in dilute bleach for a few hours and then hang them in the sun for a day or two. Then with a dozen or so masks they could be replaced every half day or so, or when you need to go out and use them.
Well unless you have a serious stash of food or grow your own sooner or later one has to go to the supermarket or pharmacist and maybe the petrol station. when hand sanitiser comes in really useful.Quote:

The message still needs to get out that masks are just a poofteenth of a % effective and wearers can't disregard social distancing, hand washing with soa\p or other requirements - just like wood working masks are not a silver bullet.
And when you get really desperate.
