Can shops still insist on customers wearing face masks?

Well said Shep ? ?

Using the Daily Fail, as respected source did give me a laugh.

As GSM has said, you and your pal have upset a terminally ill poster, shameful!

Various masks were tested under lab conditions by a company affiliated to Cambridge University.

RESULTS:

Penetration measurements for AAC-classified DOS particles between 50 nm and 5 µm are plotted below for samples cut from six commercially available face coverings.

Number penetration of AAC-classified DOS particles through various face mask materials at 160 lpm equivalent through the entire mask
Number penetration of AAC-classified DOS particles through various face mask materials at 160 lpm equivalent through the entire mask

For each penetration value the error bars represent a two-sided 95% confidence interval, which was calculated in accordance with the specifications for particle counting statistics in Clause 7 of ISO 29463-2 (based on the Poisson distribution).

For the range of flows tested in this study, the particle aerodynamic diameter with the highest penetration through the filter materials was generally a few hundred nm. Capture of smaller particles is mostly influenced by diffusion (and mobility diameter), whereas capture of larger particles is mostly influenced by interception and impaction, for which aerodynamic diameter is the most useful measure of particle size.

The impact of interception increases as particle size approaches the fibre width. Comprehensive assessment of woven materials is reliant on the ability to classify particles up to 5 μm, since it is only at this larger size range where filtration efficiency for the cloth coverings approaches 90%. In these samples the particles interact with highly ordered yarns (bundles of fibres) rather than individual fibres, which limits the influence of the interception mechanism.

In contrast, the FFP1 and FFP2 respirators tested in this study comprise matrices of randomly oriented fibres, meaning tortuous air paths and high particle collection. Particle capture is also likely enhanced by loading of static charges in these filter media. While the surgical masks are not electret media and the fibre density is lower, the amorphous matrix of fibres promotes interaction between particles and individual fibres, leading to collection of >90% of 2 mm particles.

Note: since these tests involve particle penetration of material samples sealed by an o-ring in a housing, the results are not representative of an entire face covering with air leakage around the edges.

I hope it's clear that the jury's in on this issue.

Btw, having lived in Sweden for a few years I feel I can say, with some authority, that:

- the population density is far less than the UK

- the population follow government guidance more readily than in the UK

- Swedish people tend to keep their distance from strangers, especially on public transport

She is upset because people like you, peddling dangerous and ill informed information on the Internet, encourage behaviour that puts her and other vulnerable people at risk.

I find your post above absolutely despicable.

I suspect that I may have to withdraw from this thread, before I say what I really feel about the lack of knowledge, understanding, kindness, humanity and compassion, I have witnessed on this thread.

LilacChaser they seem to believe a mask saves them from a virus! You couldn't make it up

Just give it a rest.

Are you the same person?

Don't worry Marydoll, I'm going now.

If I said what I really thought about a certain poster I would be banned. She is indeed utterly despicable and devoid of sympathy and understanding.

Fortunately there are only two mask deniers posting nonsense.In fact, on reflection,I suspect there is only one using two names and taking to him/herself.

I NEVER wear a mask now they are not compulsory. I believe now we have the vaccine we should get back to normal. I will just ignore any rules that a shop has on wearing one because it is no longer the law. Time to start living again. Those who feel unsafe should self-isolate if they want to but for God's sake let the rest of us get back to normal!

! will just ignore any rules
Those who feel unsafe should self-isolate

And there you have it folks. What an awful attitude.

I’m afraid that what the shop requires is their law, and if you don’t comply I hope you are ejected in a public and humiliating fashion. No support for your selfishness here.

He/she has multiplied Parsley. Maybe it was my hint of sex and travel?

Those who feel unsafe should self-isolate if they want to but for God's sake let the rest of us get back to normal!.
A sad reflection of how society has become.
A little compassion wouldn't go amiss. Perhaps, the clinically vulnerable should just be dumped together on a desert island, to allow the rest of society get back to normal.
I wish for normality too!

It is not a matter of feeling unsafe or getting back to normal, for some of us, it IS still unsafe, according to our clinicians. Covid is still around and continues to put us at risk.

Indeed, Marydoll! But hey, as long as "I'm all right Jack" brigade can carry on with their lives without a thought for anyone else, eh?

Or maybe we should all make th we small sacrifice of wearing a mask to make those more vulnerable feel safe and able to rejoin society.

If you are ever ill, vulnerable or marginalised in any way songstress60 and dismissed by others as not worthy of assistance and just fit to stay at home so as not to cause minor (or none in most cases) inconvenience to others I hope you will be hanging your head in shame at your ignorant and selfish attitude.

vintagejazz wearing a mask isnt a small sacrifice though is it

Well yes it is Biscuitmuncher.

Dont be so silly Vintagejazz it completely goes against human nature

In what way Buscuitmuncher?

How is it normal to be masked?

Biscuitmuncher

vintagejazz wearing a mask isnt a small sacrifice though is it

Well, it was for me. Were you to have been involved in a major road accident, or needed urgent heart surgery, major cancer surgery, a serious head injury, my colleagues and I would have made that sacrifice willingly, for anything up to 12 hours at a time, to look after you in our operating theatres.

And before you start, it wasn't because it was my job.
It was because we bloody cared.

And that's what we get in return.

I said it was a 'small sacrifice '. Anyhow you obviously live in a little bubble of your own with no sense of responsibility or concern for your fellow citizens so not much point in trying to debate with you.
