As an engineer who has had to use respiratory protection against mainly asbestosis I and many other filtration specialists have been absolutely appalled regarding the dithering and false info regarding masking up.
It is well worth anyone reading the truth of filtration and masks and particles including virues in the article by the Association of Heating and Ventilating engineers Association. This article is far more clarifying that any I've seen before. Heating engineers have been exposed to asbestos particles before they were enlightened re the fact that asbestos kills. The individuals that succumbed to asbestos lived months or years in misery. Asbestos fibres can be seen by the naked eye but mostly cannot be seen and those miniscule molecules are the dangerous ones that even 2.6% of them can get through the very efficient filtration material that is incorporated in a P3 filter.
The 'half' face respirator is usually of silicone rubber with the replaceable filters screwed or clipped into it. It can be up to 97.6% efficient against contaminants getting into the airways,
All engineers who have to know their stuff re masks must have been absolutely appalled re the false info that has been dished out for months by those who should know but probably do know better.
You may have notice the goal posts have been moved several times now |Borris says put a mask on but not a P3 one because we want them for the front line! The New York Times doctor's article exposes the lies and says the advice to not wear a mask because it does not protect has 'backfired'.
If people cannot see more masks are being worn when amongst others they must be very unobservant. Self preservation is paramount these days more than ever before. I've said it from day one of this crisis, any mask is better than no mask at all.
Of course a mask is better than none! it’s shocking how many people are not wearing masks here.all I have to do is think of my children the thought of someone coughing on me and being able to do nothing because I don’t have a covering on is awful.I would not risk not wearing a mask it’s better to be covered than not
I wear a face mask all of the time, my best friends funeral was last week, he died of coronavirus four days after being tested positive!
It’s awful a family friend died here as-well it’s not worth it as restrictions change people’s attitudes are changing not many are wearing a mask where I am
Some of us have a more acute sense of self preservation. I must have breathed some asbestos in but coughed it up in my twenties as a none smoker. At 79 doctors even now write down as a heating eng you must have handled asbestos? Yes I say right under our feet at this hospital in the ducts! When we knew the deathly dangers we wet all asbestos after of course putting a good mask on but not these thin things but a silicone half face mask with two P3 filters.
I'm sorry to hear that......My son's pal died a few months ago at about 56 with asbestosis. I just received a reply knocking the fact that any mask is better than none. The writer said asbestos is different to this virus.... Well of course I am well aware of that but I still say that if there is a chance that any virus particles stick to any fibre barrier in front of the breathing airways then there is a good chance that the infection will not get to the alveoli in the lung.
How many people breath only through their nose? I would wager not many but the nose is a far better filtration system than the trachea...... I still say any mask is better than none but the next best protection is the P3 mask...... Nothing less if you can get one and afford one.
So sorry for your loss
I read a truthful article by a lady doctor NY Times = Telling folks mask don't protect has backfired. This mumbo jumbo from UK 'the advisors' may have prompted the Association of Heating and Ventilating Engineers to put forth their 'paper' which can be seen on the net re the facts about filtration of the 'VIRUS' The article is a very comprehensive one which I hope will finally make mask compulsory in places where contact is unavoidable. Such places would be any space within walls when any other person has been before they enter that space.
Does the public know that the latest research re tuberculosis that a person does not need to cough to emit that mico bacteria if they themselves have pulmonary TB?
