what it is?

A gas mask is used for chemicals It protects from fumes from paints It does not protect gases that can

absorb to the skin Construction site use them to protect

from welding fumes

What it does?

It protects from toxic gases and bacteria

It forms a seal around your face

It helps the military from gases that they can die from

The S.W.A.T. team also uses it from seeing in the smoke

How it works?

When you breathe it activates the charcoal filter. Then through a charcoal dust filter. Then in to your lungs. But when the charcoal becomes saturates you have to replace it.

Changes over the years

Once the mask was container to a container filled with air but that was to heavy. Then with a mask with no eye protection for different uses. The new gas masks are so much lighter now.
