The gas mask is an integral part in individual protection, but it is only a component, so why do you need it?
There are many reasons, and the some of the reasons are assuming a natural disaster of some sort. Smoke from forest fires and factory fires are probably two very prominent reasons. Living near pesticide/chemical plants or near biological waste or nuclear waste areas, are also facts that might lead you to consider buying a gas mask. Other valid reasons include outbreaks of virulent disease, leaks from chemical plants, and leaks from reactors.
Please note that gas masks filter the air you breath, They DO NOT produce oxygen and should not be used in closed off environments that have low oxygen levels. A further warning, a gas mask does not protect from radiation, but it only prevents the breathing of radioactive particles, such as from a reactor breach or a dirty bomb.
That said, what kind of mask should you get? As far as a gas mask is concerned there are many variables. So how do you know how to choose the right one?
Let’s see some options.
The Old Soviet Series of Masks
The most common mask in the world is probably the old soviet series of masks. These masks are simple to use and inexpensive. They come in several sizes and are not a bad choice for those with minimal training.
