C-4 Protective Mask
A C-4 protective mask is a mask that helps people protect their face from harmful things. It is a special kind of mask that soldiers and other people wear to make sure that they do not breathe in any dangerous things like chemicals, gases, or smoke.
The mask has a special filter that helps clean the air before it goes into the person's lungs. This filter is like a big straw that you put in your mouth. When you suck through the straw, it takes the bad stuff out of the air and leaves only the good stuff for you to breathe in.
The mask also covers your whole face, like a big hat that you wear on your head. It has straps that go around your head to keep it in place so that you can move around while wearing it.
When people use a C-4 protective mask, they can breathe safely even if there is bad stuff in the air. It helps protect them so that they don't get hurt or sick from breathing in the dangerous things.
