Proper way to put on a respirator?? Hmm... Let's take a look at my references... Maybe I need more, to get a more in-depth understanding of proper preparation and operation?
glad fuckers like you are getting vasectomies
You need to put your glasses on after you don the respirator.
I don't think it matters which strap you fasten first, as long you do a seal check and it's tight enough so it stays sealed even when you move your head around and bend over.
Here's a scene from Andromeda, which I posted before...
Also, your glasses don't fog up when you're wearing a respirator, like they do when you wear a cloth mask or a loose-fitting earloop mask. But sometimes a filtering facepiece respirator will fog up glassses even if you have it on tight because the exhalation breath comes out from everywhere through the filtering material, even near your glasses.
@lucifargundam I'd love to see them doing that while wearing glasses. :P
