Explore the science behind how gas masks work, and how the technology protects us from airborne threats and pollutants.
--
You might think of gas masks as clunky military-looking devices. But in the near future, we may need to rely on these filters as part of our everyday lives. In addition to emerging diseases, wildfire frequency has more than tripled, and climate change has increased toxic ground level ozone. So how do these masks work, and can they protect us from airborne threats? George Zaidan investigates.
Lesson by George Zaidan, directed by Michael Kalopaidis, Zedem Media.

@henrythepotatohead 19 дней назад

Hate to be that guy, but technically, the bonds for nitric oxide and nitrous oxide are depicted incorrectly: 1) Nitric oxide has more of a double bond + a free radical (•N=O), though the radical can sometimes be depicted as a third bond (drawn as a dotted line, NOT solid line!) to show "resonance". This dotted line is shown correctly for ozone as it resonates between (O=O-O) and (O-O=O), thus the structure can be "averaged" to give a dotted line throughout the ozone molecule. 2) Nitrous oxide can be drawn as (N=N=O) or (N≡N-O), but NOT a single bond (N-N-O)!

Yeah, I kind of see your point. They’re both man made horrors and both have the chance to wipe us off the planet. Although I think the whole “duck and cover” method of those nuke drills were a lot less useful than knowing about and having access to masks and other modern advanced filtering technology. Hopefully we can stop climate change like how we’ve worked to disarm our nukes. Humanity usually finds a way to prevail in these situations, even when it seems too late.

It honestly looks like an exaggeration, at least in the US. Wildfire number is pretty consistent according to the United States Environment Protection Agency, bouncing around 70,000 per year since they started watching in the 1980s. The area burnt has gone from about 3 million acres to about 8 million, but that's nothing compared to the 2.4 billion acres of US land. Some states even averaged proportionally less land burned since 2002. Maybe it's a bigger concern somewhere else, but it's not very concerning where I'm looking.

@RWMAirgunsmithing 17 дней назад

The van der waal force might be what clumps aerosols together but this is not part of the filtration principles. Air filters work by interception, impaction, diffusion (brownian motion) and electrostatic forces (depending on the media, aerosols and media condition). Your analogy of representing the media with a forest is spot on, it is how I explain things to my customers, a 1 micron particle going through 1mm of media is like a fly flying through 1km of forest (roughly speaking), the odds are practically nil that it will make it across but the air can still blow through.

A kinda_dystopian-ly_animated video that talks casually about the world being orange, people wearing masks everyday and everywhere being the norm, and fires happening constantly, in large scale, and near your house, with its smoke haunting every single part of the city. That's probably the scariest and most effective argument I have seen regarding air pollution. If the numbers really show that that's our near future, I'll be very convinced that this is a priority. I don't wanna live in that world. Suddenly, I see the importance of being able to breathe without getting sick, to breathe without a mask (they're sooo uncomfortable), and to have a blue sky.

Imagine fighting in WWI before anyone knew about gas then the German unleash it on you. You have no idea what is happening as everyone is dying around you then it hits you.
