So that you won't inhale anything poisonous.
yes gas masks were used
The use of masks goes back to the 1800s when inventors developed masks for the miners and soldiers. We still have our soldiers outfitted with gas masks.
There are several company's selling and inventing new gas masks.
The Germans on the Western Front
In the Metro 2033 universe, the gas masks used by the survivors are commonly referred to simply as "gas masks." They are essential for protecting against the toxic air in the post-apocalyptic underground environment. These masks often have filters that need to be replaced regularly to ensure safety from harmful contaminants outside. The gas masks are a critical piece of equipment for traversing the dangers of the metro system and the surface.

You don't put gas into gas masks. They are used to keep out poisonous gases.
Yes. Horses and dogs used gas masks; however, the animals were often forgotten or had to use simple cloth bags over there noses. Of the few animals used in the war, they had much higher casualty rates partly because they rarely had gas masks. Sometimes 5,000 animals would go in, and only 200 or so would return. They even had special "goggle" to protect animals' eyes from gas, but animals rarely got to use them. Carrier pigeons used fell from the sky because there were never gas masks for them. Nevertheless, mules, hoses, dogs, and yes even sheep and goats had gas masks, but only if they were lucky.
Not all gas masks are compatible with helmets, so some soldiers forgo helmets to wear their masks.
Soldiers in the trenches got gas masks after the need became apparent. Chlorine gas was first used by the Germans on April 22, 1915. Mustard gas was used in 1917. 30,000 died from the gas and 50,000 troops were injured because of gas use. Gas masks did not work with mustard gas because that burns the skin.Here is a first hand account of gas warfare.http://www.eyewitnesstohistory.com/gas.htmhttp://chemicalweapons.cenmag.org/when-chemicals-became-weapons-of-war/
