Ontario is going to reopen schools on schedule in September. High school students will attend on alternating day with class sizes limited to 15. Elementary students will go back full time with a maximum classroom size of 24 and be cohorted for all classes, lunch and recess. The education minister said they cannot guarantee two meter separation between desks. Grades four and above will have to wear masks inside the schools.

This is absolutely nuts.

If your glasses are fogging up, breath is coming out and not properly sealing. I don't see much of a difference.

The difference is water vapor vs droplets. Those masks with a one way seal and no carbon filter allow raw breath to escape. Fog coming from around a mask is just water vapor, not droplets. Water vapor is unlikely to have virus particles because it is gaseous. Water droplets will have virus particles in it.

From the cdc....

An N95 respirator with an exhalation valve does provide the same level of protection to the wearer as one that does not have a valve. The presence of an exhalation valve reduces exhalation resistance, which makes it easier to breathe (exhale). Some users feel that a respirator with an exhalation valve keeps the face cooler and reduces moisture build up inside the facepiece. However, respirators with exhalation valves should not be used in situations where a sterile field must be maintained (e.g., during an invasive procedure in an operating or procedure room) because the exhalation valve may allow unfiltered exhaled air to escape into the sterile field.

On edit, I have used these before which is why I'm familiar with them. They help quite a bit when working in hot, confined spaces with a lot of dust or particulates, like when I grind fiberglass in an enclosed compartment. They aren't meant for pandemic social distancing.....

A lot of folks probably have never worn a mask up until this point. You think they realize that those ports are harmful? Does someone piss in your wheaties every morning?

We are doing something similar in a few months.
Would you be so kind as to recommend (effective & comfortable) ones from say. . . Amazon?
Also, would spray alcohol be the recommended disinfectant for one?

I've been dealing with my main machine acting up and have to head into San Bernardino today. So let me take a look this weekend and see what Amazon has but anything based on 3M's 7500 series is golden. I keep thinking I should have gotten a full face for ease of use. If you're sporting a beard or goatee affair you may have to trim it for adequate seal. Safety first you know.

I clean mine with disinfectant wipes, you'll need to carry some. Alcohol is drying and will age it faster.

Saw some people wearing masks with an exhaust port. What selfish bastards. Those ports don't filter your breath, they just make it easy to exhail and keep your glasses from fogging up. They are meant to protect the person wearing one, not those around you. Sure, it might contain droplets from a sneeze, but cough and breath droplets are flying right out.

Yeah if this shit is aerosolized which I suspect from infectivity rates it's frustrating. That's why throughout this entire clusterfuck I've worn a respirator. I spent to many years in the OR fixing idiots to assume anything they do would protect me. But I do roll my eyes when I see some of their reindeer games.

Wow, that’s scary! I just watched a Delta airlines video showing how they clean the airplane so Thorough using a special fogging mist every night and carefully wiping down all the surfaces. Be nice if it were believable. I don’t trust that is very detailed work and so much can be missed . All the little areas and seat belt details . You gotta do it yourself to be sure

Canada's covid alert app was released today... for Ontario only. Almost two months late lol. I just installed it, looks like everything is done over bluetooth. It's telling all devices that come within bluetooth range what its id is. If you tell the app you have covid it will send notifications to all devices that you came in contact with in the past two weeks.

Florida announced it is halting trumpvirus testing because of the hurricane approaching. The whole state. Rarely is the whole state impacted by a storm, and this isn't much beyond a cat 1. Sure, some coastal areas could see disruption, but not the whole state.

The fish are rotting on the beach down there.

I thought they were leaving west coast(of florida) testing sites open, did that change in the past couple hours?
