MOPP (protective gear)

Mopp is like a special suit that people wear to protect themselves when there are bad things in the air that can make them sick or hurt them.

First, they put on a big jacket and pants that cover their whole body to make sure no bad stuff can touch their skin. They also wear big gloves and boots to protect their hands and feet.

Then, they put on a gas mask that covers their nose and mouth. This helps them breathe clean air so they don't get sick from any bad stuff in the air.

Lastly, they put on a big hood that covers their head and keeps their face and eyes safe too.

When they wear all of this together, it's called "mopp gear" and it helps keep them safe when there is danger in the air.
