Please set me straight. I must have missed something. My impression is that a cloth or paper mask, as generally available, when worn properly over the mouth and nose will effectively protect other people from the egress of your spume. These masks are not designed to prevent the ingress of SARS-CoV-2 for which a fitted mask would be necessary. The egress of the small amount of the possibly virus-laden spume that escapes around the edges of your non-fitted mask is diluted over the 6-foot distance that you maintain from other masks wearers. This dilution effect is enhanced by an outside breeze or by effective ventilation of inside spaces. Isn't a goal of controlling this pandemic is to keep the viral load to which you are exposed as small as possible and to break the transmission link between people with simple mask plus distance behavior?

The rules are all here where John told us:

 

https://www.dhhs.vic.gov.au/facemasks-covid-19    the crux is:

 

You must wear a face mask when you are leaving your home unless you have a lawful reason for not doing so. =46rom 11:59pm 11 October you must wear a fitted face mask that covers the nose and mouth. This cannot be a face shield, bandana, or scarf on its own. A face mask needs to be worn covering both your nose and mouth.

 

A fitted face mask is now required instead of other face coverings because it provides better protection. As restrictions ease and movement increases, the effectiveness of a face mask is even more important.

A face mask includes any paper or textile covering designed or made to be worn over the nose and mouth to protect the wearer. It does not have to be medical grade and you can make your own. There are instructions on how to make a mask on the Department's website - How to make a mask. (There is a live link here to directions on what polyester materials to make a mask out of, the dimensions, etc.)

 

=46rom 11:59pm 11 October you cannot wear a face shield on its own. You can wear a face shield with a face mask.. If you have a lawful reason for not wearing a face mask, you can choose to wear a face shield on its own. A face shield means any film made from plastic or other transparent material designed or made to be worn like a visor, covering the wearer's forehead to below the chin area and wrapping around the sides of the wearer's face, to provide the wearer protection.

Hi,

 

So how do we define "proper"? Does it mean the mask has to be externally validated to a certain standard? N95 etc? Especially if the cops on the street have to enforce this then needs to be some easy to identify metric.

 

 Faceshields are easily distinguished but a scarf or bandana tied over nose and mouth vs a "proper" but homemade mask may be not obvious? Just curious. 

 

 PS  Sorry I was too lazy to read the Melbourne regulation!  Maybe it says what proper is!

ALL,

If you had not heard or read, effective Monday, October 12, 2020, Victoria, a federal state in southeastern Australia, has banned face shields, scarves and bandanas under the Melbourne COVID restrictions.  =46rom the Department of Health and Human Services (Victoria) advice, those items no longer meet the test of effectively covering the nose and mouth.  Beginning 11:59 PM local time, on Sunday, October 11, 2020, the police can begin fining those people wearing an improper face covering $200AU ($144.67USA).  Everyone must leave his/her home or other place of residence wearing a proper mask unless an exemption applies.  The Chief Safety Office has recommended a face mask with three layers as the best option.

Do you think that could happen in the United States?

Be Safe, Secure & Sound in Judgement, Vigilant as Always, and Stay Well!

Have a Restful Weekend if you can.
